Zero, by Way of a Hundred

This episode of *Risk of Ruin* examines short-selling through the lens of John Hempton’s experience with Valeant Pharmaceuticals. Valeant, once a $200 billion company, collapsed after Hempton exposed its fraudulent business model of price hikes and hidden ties to Philidor, a mail-order pharmacy that conspired to overcharge insurers. Despite being certain of the fraud, Hempton endured a painful ride as Valeant’s stock rose from $130 to $260 before crashing to $15–30. The key lesson is that having an edge is not enough; you must manage risk of ruin. Hempton uses tiny position sizes (under 1%) to avoid being wiped out by a stock’s temporary rise. He also emphasizes the importance of finding many frauds globally, using computers to scale. The current market, with millions of inexperienced retail investors, amplifies opportunities for short sellers. Hempton’s success transformed his small Australian fund into a major player, but he warns that shorting requires patience, discipline, and a focus on negatively correlated returns. Ultimately, the episode highlights the balance between exploiting an edge and surviving the volatility inherent in shorting fraudulent companies.

[Music] You have an edge. There's a stock out there that might be trading to $300 million and it's worth nothing. It's an edge. The question is, is it an exploitable edge and how do you exploit it without risk of ruin? [Music] Risk of ruin is a podcast about gambling and life and their intersection. I'm John Reader. This is episode 23 Zero by Way of 100. [Music] If you follow the financial markets or if you've ever seen the Netflix documentary titled "Druck Short", then you know the name "Valient Pharmaceutical". In the summer of 2015, "Valient Stock Traded" for about $250 a share and then eight years later, it was like $25. That's quite a reversal so let me detail some of the highlights from the ride down. First, "Valient's Entire Business Model" which was like "Martin Screly" on steroids, came under intense public scrutiny, then "Short Sellers Accused the Company" of using a shady third party to juice sales numbers. There was an emergency conference call to try to keep the share price up. The CEO was eventually fired, some prior year earnings were restated, a handful of people either went to jail or paid fines for misconduct. Also the name "Valient" became toxic for investors, Congress, the public and even other healthcare companies like CVS. So eventually they changed the name of the company to Bouch Health. "Valient" is probably the biggest and best win for short sellers over the course of the bull market. Critics of the company alerted the market to wrongdoing and they made money on their bets. One of the short sellers was John Hempton. He runs Britey Capital in Australia. "Valient" was one of the seminal events in my life. For those that don't know, "Valient" was a very big American pharmaceutical company, peaked out at well over 100 billion market cap, almost 200 billion. And it was a company that bought other companies for their drugs and raised their prices. And in fact it had no real other business model. The first thing it did when it bought a pharmaceutical company was sack all of scientists. They were all the cost structure. All they wanted to do was raise prices. And the problem with that is it's a highly decaying model. If you don't keep churning out research papers, you can't expand the label on your drugs. If you don't keep developing stock, you won't wind up with the best drugs. And at some point, "Valient" started baking its accounts. We're very, very good at determining fake accounts. It just struck us that "Valient" was obviously bullshitting. And yet, you know, there were hundreds of, well not hundreds, but dozens of big name US investors that thought that "Valient" was the best stock in the world. And the market approved them right. You know, "Valient" went up and then it went up some more and then it went up some more. And as they started baking their accounts or baking the story, it went up further. Right? So this was a classic situation where they were baking their accounts, they were baking everything. The stock was going up and everybody on Wall Street that had picked the stock early thought that they were genius. And they were marketing themselves as geniuses. And along comes this little fund from Australia that, for honest, only a few cognizant he had heard of and said the Empress wearing no clothes. And it turned out, yeah, the Empress wearing no clothes and a couple of the people associated with "Valient" have now gone to prison. Right? Now, before that, we were a fund in Australia that had interesting results. But we were operating from a beach suburb in Australia, on die. We had no Wall Street pedigree. We didn't look like anybody special. And there was a question about the sustainability of it. And after that it was like, hey, these are the giant killers. So we had a combination of fairly good numbers and we had been very publicly right for the right reasons. And being very publicly right for the right reasons, about the same time I hired a sales guy who was highly competent. And the combination worked exceptionally well. So yes, you know, "Valient" was a central event in my life because it helped us raise money to the right reasons. And if you're going to manage money, it does help to manage a lot more than a little bit. Right? So before "Valient", what we had was a nice business for a small business. And after "Valient", what we had was a very nice business. The smoking gun in the "Valient" case, the revelation that sent the stock price tumbling, was the company's relationship with a mail order pharmacy called "Philidor". You can think of "Philidor" as a dedicated sales channel, which allowed "Valient" to offload scummy tactics to a third party. For instance, maybe "Valient" had a branded skin cream that sold for hundreds of dollars per tube. But there was also a generic that sold for like ten bucks. Well, "Philidor's" role was to push the expensive cream and stick insurers with the tab. So in simple terms, "Philidor" and "Valient" conspired to fleece insurance companies and by extension fleece people that pay for insurance. But the kicker, and my favorite part of the story, is while "Philidor" was supposed to be helping "Valient" stick it to insurers, the CEO of "Philidor" couldn't help himself. So he decided he should probably steal at least a little from "Valient". This is "Preet Bharara" at a press conference when he was US attorney for the Southern District of New York. Specifically today, we have arrested and charged two men, Gary Tanner, a former senior executive at "Valient" and Andrew Davenport, the founder and CEO of "Philidor". We alleged that these two men participated in a fraudulent scheme to illegally use "Philidor" as essentially a vehicle for personal profit and self-dealing. As alleged, these two men reported to be arm's length business counterparts, Tanner "Valient" and Davenport with "Philidor". But they were in fact, we alleged, partners in crime. "Philidor" is only important for our purposes because it shows the fundamental reliability of people. And that reliability is core to John's strategy. If you find some folks running one scheme, the odds of finding them in another scheme increase by a lot. People are amazingly dependable. Anyway, before October 15th, 2015, almost no one had heard of "Philidor". Even though more and more "Valient" sales were flowing through "Philidor", they'd never been mentioned in a "Valient" filing. But John found them. People don't have 600-person staffed entities that they don't disclose at all. You couldn't find anything out about it online. And when we started digging, it was pretty clear that they didn't want us digging. John mentioned "Philidor" to the journalist, Rady Boyd and the short seller, Andrew Left, which set in motion a chain of events that would eventually tank "Valience" share price. On October 15th, John wrote a cryptic blog post that didn't say much more than just the word "Philidor". Then, on October 19th, Rady Boyd published an article linking "Valient" and "Philidor". Finally, on October 21st, Andrew Left issued a report calling "Valient" the next "Enron". The rest is history. The usual problem we have with shorts is you've found them lying three or four times. And now, you don't know when they're telling the truth. It's a general rule, actually, in the stock market, that if you talk to the management of a company and you believe what they say, almost every company looks like a buy. Now, every now and again you catch the management team lying. And once you've caught them lying, if they tell you X, Y, Z, you don't know whether to believe them anyway. So, we've caught "Valient" on three or four small lies and then we found "Philidor". And "Philidor" was obviously a big lie, but we didn't have any particular understanding of it. We knew it was key in some respect because it was so large and so well hidden. Now, I actually did pass the information on to Rady Boyd and Andrew Left. I regret passing it on to Andrew Left. I got nothing back from him and I was hoping to because he was a fellow short seller. But he also gzumped me a little bit on the short. And I was actually quite upset with it in respect. Rady Boyd, I passed it on to as a journalist. And journalists, you do not expect them to give you anything back. And the whole thing about journalists is that they're meant to do their own research and publish it. And there have been several insider trading cases where journalists have told investors what they're going to write. When I passed it on to Rady Boyd, because he was a journalist, I didn't expect anything back and I didn't get it, Rady acted with utter integrity. Now, when I passed it on, I knew it was big. I knew it was important and I didn't understand it at all. It's like, imagine you had stumbled on this massive industrial plant in Norway where the Nazis had huge amounts of security around it, where vast amounts of money are being spent. And you can't work out what it's doing in that case, which is a very famous case. It turned out to be a heavy water plant and was the beginning of maybe a Nazi atomic bomb program. If you had stumbled on it, you would know it was big and important. But realistically, there were probably only 200 people in the world. that could work out what it was. I wasn't one of those 200 people. But to give Roddy credit, Roddy would down about 85% of it any worth it out himself. I framed the valiant episode to make short-selling sound easy. Just find a shady company, dig up some dirt, watch the price collapse, profit. But reality is always more complicated. Let's look at this another way. In May 21st of 2015, valiant was still marching towards its all-time high and it would be another six months before Filador became public. On that day, John tweeted, "Okay, I confess. Valiant is one of many shorts, mostly pharma that I wish I had never heard of. Still short, but hard to profit from here." We entered at about 130. There was a little bit more added at 160 or 70, but never enough that we were squeezed out. The stock went to 260. At one stage, valiant was one of the biggest losers in my portfolio. We had it absolutely nailed and we were very sure we were right. I eventually exited the shorts at prices between about 15 and 30. It worked out okay, but it still had that characteristic of fraudulent companies, which is fraudulent companies go from 10 to 0 or in this case 130 to 30, veer in numbers that you don't understand. We started with the story of valiant because it illustrates the promise and the pitfalls involved in shorting stocks. It was life-changing for John Hempton and it was also a roller coaster ride. He's been at this a long time and he's seen a lot of these things, so he's going to walk us through what these short ideas look like and we'll also see how valiant fits the broader type. In Perth in West Australia and also in Vancouver, there is a large industry doing fake gold stocks. The idea is that you peg a whole little land, you tell people that it's got gold and you're not really mining for gold, you're really mining for money on the floor of the stock exchange. These people bring to mind Matt Twain's famous definition of a gold mine, which is a hole in the ground with a liar on top. Now imagine you know for sure that one of these gold companies that claims to have a million ounces in the ground has no gold at all. You can actually know that for sure in certain ways, if there's gold in them, there are hills, there's gold in the creek below the hill. If you hire a professional planner and you go and pan the creek below the hill and you don't find any gold, then you know for sure that there's no gold in the hill. In fact, you don't even need to hire a professional planner. All you need to do is contact the local regional, you know, country town librarian and there'll always be history of the area, you know, that somebody's written and the librarian would love to talk to you and they'll give you a history of the gold panning in the area. There's always one and if there's no history of successful gold panning in the area, then you know there's no gold in the hill. Okay, so now you know there's no gold in the hill. You have an edge. It's an edge. Suppose you have done this and you decide, okay, now they've got this edge. I'm going to short 5% of my, well, use the gambling term, my role, you know, my gambling role or 5% of my portfolio in this stock. Most of the time the stock is going to go to zero and over a two to three years you'll add 5% to your portfolio and if you can do that four or five times a year, you're Warren Buffett, right? Because, you know, index plus 15 is better than Warren Buffett. Sounds pretty good except it doesn't work that way and the reason it doesn't work that way is that the one thing you know about this guy is he's a liar. He's already lied and told you that he has a million ounces and there's a fairly good chance that he's going to lie until he has 10 million ounces. You know, finding a million ounces of gold is hard, finding 10 million ounces of gold is even harder. Lying about a million ounces isn't that hard and lying about 10 million ounces is no harder than lying about that. Now if the market believes him, this stock that you've decided is a short 5% of your wealth in or 5% of your role in if you wish to be a gambler is going to go up 10 fold. And so instead of being 5% short, you're now 50% short. Except he had a problem which is the capital has gone from 100 to 55 because you've just lost 45% of your bankroll and so you're now over 90% short. And if you 90% short a single name your good friends at Robin Hood or Interactive Brokers or in our case Morgan Stanley and JP Morgan are going to put you out of business and they're going to put you out of business on the stock on which you're right. And so what you have is an edge but it's an edge that's exceptionally dangerous to exploit. So that's the problem and it's not much different than the gambling problems we cover. The issues are find an edge, figure out how much to bet and stay in the game. Addressing those issues also means solving a bunch of related puzzles that we'll get into. But the first question for any gambler or investor is always should I play at all? Because you don't have to play this game, you can always go find something else. Maybe there's something with a better edge or less volatility. And to be fair, lots of managers actually have thrown in the towel on shorting stocks. We've decided the pleasure just isn't worth the pain. But I think the simplest way to illustrate the potential of shorting is that if you want returns that beat the market and you want returns that are uncorrelated to the market, one way to get there is to make some bets which are actually negatively correlated to the market. So if the whole market dumps your shorts go up and you can buy discounted quality companies. There are entire books written about this kind of thing but John recommends the book "Expected Returns" by Auntie Elmainen of AQR. One of the attractions of the stock market is that you can get an enormous number of bets per week. Although take my gold mining example, the typical path to zero for that gold mine is five to ten years. It's actually not a very good return. The only functional part of that return is that it's a negatively correlated return. If you have an asset that actually breaks even over a cycle but is negatively correlated and you pair it with an index, you'll do just fine. Thank you. There's a lovely book on that incidentally. One of the best books I've ever read which is called "Expected Returns". Now the expected returns book makes it absolutely clear what the value of an even slightly negative return but very strongly negatively correlated asset is and the answer is a lot. And it's a quite a good book on how you might think about the portfolio construction. You've probably gotten an email at some point typing a "can't miss" stock that you've never heard of. You look at the email for less than a second and then hit delete. Even if the email doesn't look overly scammy, which usually they do, the very idea of marketing stocks randomly via email is a red flag. Well John gets those same emails but he doesn't delete them. But very early on in the piece I discovered, I guess what you'd call early 2000s penny stock frauds. And the early 2000 penny stock frauds were, well, it was really ridiculous. It was stuff that was sent to you in spam emails. Really crappy stuff. And it turned out that you could short $5,000 worth of these things but you couldn't short $50,000. And I started a little TA account, personal account, where I systematically started shorting these things. And I realized that you could turn $30,000 into $500,000 pretty quickly doing this. But you couldn't turn $500,000 into $5 million because you became scale-in. Now, but what this taught me was that there was a massive sort of underlying scummy part of the stock market. When we started looking for the bigger caps, it was interesting, but originally it was hard to do. Again, I thought that we could probably work out how to scale it to $30 or $50 or $100 million, which was an interesting number. But it wasn't going to make a very big fund. And then two things happened. One thing that happened was we just got much, much better at finding these things with computers. And that turned our scale limit from, say, $30,000 to $300. But that required an enormous effort. It required that we go completely global. The big, heriordacious goal of trying to find every fraud stream in the world in stock markets. The second thing that happened was the market went up. And then it went up some more. And eventually vast numbers of retail investors with absolutely no edge jump in the market. So at the moment, during the crisis, something like 40 million people in the United States opened retail banking, breaking accounts. And I remember the last time that happened, it was sort of dot common in that time. It was sort of 2 million people open retail banking accounts, of which I was one. And when I looked back at what I was doing, I was like, "Oh, I'm so sorry. did when I first opened my retail-broken account. I looked you in the I and say I was a goddamn idiot. And the only reason that I didn't blow up was that I did it in 1994 rather than in say 1999. And I had read enough books by 2000 to realize that it was all going to end in tears and I had reject appropriately. But when I look at the people that opened in 1999, they all looked like they were geniuses for a couple of years and then they all looked like there were zeros. Now that's what happens when two million people open retail-broken accounts. This time it's 40 million people. The amount of people that are gambling on crappy stocks where they have no age is extraordinarily large, larger than any time in human history. The way I described the stock market at the moment is it's a market in which people investing companies in which they've never heard of recommend along the internet by people that they've never met. Sometimes with money that they don't have. So yeah, what we thought was going to be a small opportunity because of history and because of computers became a big opportunity. Remember from John's Goldmining example that one of his goals is to make sure that no single name can hurt too much. So his position sizes are very small, less than 1% per company, but that also means he needs a lot of companies to short. I want to find every fraudulent Goldmining company in the world. And actually don't care if I'm wrong a little bit. And the sort of example is if I can short say one fifth of one percent of that hypothetical Goldmining company I talked about, but I go and find all these friends. All the people he hangs out with, all of the people he does, all the people he's involved with. Joe's a fraudster, it's likely the five best friends that Joe has are also fraudsters. Rather than short 5% in Joe's fraudulent Goldmining company, I'd probably prefer short 20 bips in Joe's fraudulent Goldmining company and 25 of these best mates. The process of generating short ideas is part pattern matching from years of experience and part technology. The solution one for us is just find all of these people and the way that we find them is with computers. Right. The job is there are three underlying assumptions. The first assumption is once a scammer or ways a scammer. And that's mostly true that I can assure you that I can show you successful businessmen that are completely honest that started life as scammers. But again, it's true on a probability basis. The second assumption is if you hang out with scammers, you're probably a scammer. And again, that's statistically mostly true, but it's not admissible in a court of law. Right. And it's not admissible in a court of law for a very good reason, which is the doesn't constitute proof in any particular way. But as I said, it's pretty identifiably the case. In some sense, you know, my standard or following a person is the Territops. It's a US Supreme Court standard for when it was acceptable for a policeman to pull over a car, which is do you have a reasonably articulable suspicion? Right. And the third assumption is if you invest in scammers, you'll mostly lose money. And I invert that, which is if you short scammers, you'll mostly make money. That makes sense in theory. But how does Brian T actually do this in practice? We have some software vendors who come from inside the beltway and sell to government agencies in the US with three letter acronyms. And their problem is roughly our problem, which is that the way that they might track terrorists or the way that they might track criminals is by relationships between people. And so we're actually the first financial institution to be clients of these, of one of these companies. Now, I'm going to tell you that at least part of what we have is vaporware, meaning we can do maybe 25, 30% of the job that way. But if you come back in two years, it might be 65% as a job that way. And in three years time, it might be 85. And when it gets there, we will get more computerized. But it's there's multiple tools. And a very simple tool is that I, for instance, signed up to every penny stock newsletter in the world in about 20 years ago. And I have a database of about one and a half million now penny stock newsletters. It's certainly over a million. I haven't looked at the number. And these are letters sent by people we knew to be scumbags in say 2005. That database is getting more and more organized than it's getting more and more organized with computers. But I'm going to confess that if the penny stock newsletter came to us in the year 2002, it's a it's in a disorganized structure. And if it came to us last year, it's in a very organized structure. Right? The computer programs just get better over time. And I wish I had been more organized in 2002 about how to do this. But I wasn't the other day. I was reading an article about a crypto scam where the perpetrators ran off with a million dollars. And by the time they were charged with fraud for that incident, you know what they were doing? They were running another crypto scam. Again, people are amazingly reliable. If you know enough geology to work out X is a fraud. Our assumption is that if the person's done a fraud, the next stock is also a fraud. And we can be mistaken on that. Right? We will put a short on based on a person alone. But the person alone we have fairly heftily determined was a fraud. The first time he was around, which might have been 15 years ago. No one is going to win every bat. So when you lose, it's important to be able to figure out. If you are wrong or just unlucky, basically, should you make the same bat the next time around? The first way we're wrong is that we're not wrong. It just goes from 10 to 0, beer, a hug. And the second way we're wrong is that we're actually just wrong. Like, you know, this gold money really does have gold in it. Right? For this drug that we're short really does work. And if I break down the sort of long history of the firm, we have far more type A errors than type B errors. Moreover, the type A errors hurt us far more. And the reason for this is, imagine I'm short this gold wine. I think it's a complete fraud. It has a market cap of 2 million out, a 500 million, and it has 2 million out ounces. Well, if it's a complete fraud, then it should go to 0. But the problem with it going is that it could go to 0 via 10X because if they're baked 2 million ounces, they might as well bake 10 million. If it's a real gold wine, it's not going to go to 0. In fact, it's going to double. Right? And it will double as they take the gold out of the ground, distributed it in cash to you. But it's not likely to go up 10X. And the reason it's not likely to go up 10X is that it's really, really, really hard to find 2 million ounces of gold. And it's extremely unlikely that the guy that found 2 million ounces of gold and is completely real is going to turn around and find 10 million ounces because it's really, really, really hard to find 10 million ounces of gold. That sort of stuff doesn't happen twice to the same person. Well, not very often. Right? So the net effective which is, I'm far more likely to lose money on the stock if I'm right than if I'm wrong. A real world example of this idea is the Bankrupt German company Wirehard. You can think of Wirehard as roughly twice the size of Theranos and about 20 times as malicious. By the time Wirehard collapsed, they had a former Libyan intelligence officer stocking journalists. And they also got the German regulator to file criminal complaints against those same journalists. If a stock goes from $10 to $0, they are $100, I'm going to lose money on it. And the reason I'm going to lose money is when it's $60, the position is now to be so I'm forced to cut it some. And when I cut it, I think that I make a loss. And you might think this is a big problem, but it isn't. The biggest loser in the history of my firm was a very big German fraud. Could Wirehard was probably the biggest fraud in European history. It blew up spectacularly in 2020. And everybody seems to think that I was very clever for working out that Wirecard was a fraud. But I promise you I wasn't. I worked it out in 2009. At that point, the stock was 9 euro and it peaked at 191 euro. And last time I looked it was 7 euro cents. Wirehard went to the moon and then it came back to Earth. On the way up, there was only one thing that could be done about it. It wasn't that bad. And the reason was that we covered the little bit every year on the way up. And so whilst we started 1% short and the stock went up from 9 to 190, which sounds like we should have lost 20% of the fund. It turns out we lost about 4.5% of the fund over a decade. That's 40 bits a year. And at some point or other, your clients are going to ask you and the ones that did ask us to explain it. And we actually went through it. And later that just makes us look smart. Right, because we spent quite a lot of time with the most sophisticated case of the Vow clients explaining the disease. and all of that makes me look very smart and retrospect, but thanks I'd prefer a refund. And I knew it was going to blow up sometime. I just thought, you know, in 2000s, can I tell it, well that's the year in 2011. I thought, well that's the year in 2000. And by 2019, I was scared to add to it on the way down. And the reason I was scared to add to it on the way down is that it hurt me so much on the way up. Right? Because by this stage, this was something that had beaten me around the years. And the end was nine, you know, they had they had investigations into them. They had audit reports. There was $1.8 billion that nobody could seem to find in the Philippines turns out 1.8 billion was never there. Right? But nonetheless, it was getting to the end. And I should have just been throwing more and more and more money at the show. And I was scared. Some of the people I approached for this podcast bristle at the idea that what they are doing is gambling. They think of gamblers as people that buy lottery tickets, not people that make careers offer pitable edges. But John agreed to come on the podcast precisely because it's about gambling. He's curious if any of the gamblers that listen might have ideas about how to better manage his position and sizeings or how he could remove the motion from the process. He's open to the idea that gamblers might have some understanding of math that could help him. Although he's already considered and discarded some of the obvious ideas. For instance, he's thought about whether he can make bets in proportion to his edge, i.e. Kelly bets. But the wire card example shows why full Kelly bets would be a tough road. But it means that somebody in my position can't bet Kelly. And the reason they can't bet Kelly is that their business will not survive a Kelly betting process. I'm not even sure they can bet half Kelly. If you've got an edge in order to exploit it properly, at least at size, you would need to be able to quantify it. I find that very hard. But you'd also need clients that can accept what you're doing and are prepared to come along for a very wild ride. A reasonable question might be, if Bronti can stay short a stock for a full decade when it's gone 20 x in their own direction, are they even capable of giving up? We have a hard rule which says that if we've lost five percent, now remember, it's very hard for us to lose five percent on a single net. And the reason it's very hard is that our typical sizing is sort of 50 bits. But we have a hard rule that says if you lose more than five percent on a single name, yeah, you just give up on that name forever. We've never hit the hard rule. Not once. The closest we've ever come is wire card. But the hard rule is still annoying. We have given up on names because the most common reason we give up on a name is imagine a typical biotech fraud that has a market cap of 250 million or 12 million of cash. And it's telling you about this drug that it's going to make and you know that it's not going to work. But the Wall Street doesn't know and the stock goes from 100 million to 400 million. And then because it's a hot stock, they raised 200 million. So now it's 600 million dollar company with 200 million of cash. And then the stock halves, it's still a 300 million dollar company with 200 million of cash. And we have to get up, right? Because by being a fraud, the company turned real. So yeah, we've given up on names like that as well. But we don't not watch. We would prefer watch with computers. And the reason we would prefer watch with computers is that that deep personalizes anything I can do to sort of be emotionalized. It's a good thing. But the goal here would be to watch it because you don't know where the people are going. And maybe they got away with it this time, but that doesn't mean that they'll get away with it next time. The other thing is we've occasionally gone back. We've had one of those companies then spend two cents the cash. So they're now down to only having say 70 million of cash. And most of that cash has been spent on salaries for the senior execs. So they've just lifted 130 million. And then they had another hot drug and they're suddenly a billion dollar company. And I want my computer to flag that. But there are several reasons for keeping the bit small. One is that you don't know the optimal bet. That's why it's half-kelly, the third-kelly. But the second reason for keeping the bit small is the emotionalized. And if it de-emotionalized is that you can come back more and more times, I want to use computers. I want to use math to find positions. And the reason I want to use all of that stuff is so that I don't have to feel like it's me against the world. Right? Because the moment I start thinking it's me against the world, I'll get depressed. I'll also make bad decisions. One name that John actually has given up on is Tesla. There's an old saying on Wall Street that if you mixed originally attributed, I think, to Charlie Munger, which is that if you mixed turds with raisins, they're still turds. Elon Musk is the single best example of turds mixed with raisins I've ever seen in my life. Elon Musk bought a company that made from his brother that made solar roof tiles and put a whole lot of roof tiles on houses and pretended that they were solar panels and faked the demonstration. I can't even imagine doing anything so fraudulent. But Elon Musk is also the CEO of a company that took a rocket up to the space station and then landed it on a barge in the middle of the Atlantic Ocean. I can't ever imagine having that much achievement. And the problem with Elon Musk is you have one of the most bizarrely fraudulent promoters I've ever seen attached to one of the most successful CEOs I've ever seen. And he's what you might call turds mixed with raisins. And the problem here is when I see the turds I short it. And because once you've seen somebody lying once, our slogan is once a scumbag always a scumbag, second slogan is if you hang around with scumbags, you're probably a scumbag. And Elon looks like a scumbag at one side of the mirror and on the other side of the mirror he genuinely looks like a genius. And maybe Elon is that sort of once in a generation scammer, real person, genius developer fraudster all rolled into one. And yeah, when I found Elon lying, I shorted him and I lost money. I'm not the only one. Right. And then I had to question my assumption of once a scumbag always a scumbag because the guy is also the CEO of a guy that of a company that took a rocket the space and landed it on a barge. You know, the guy has more achievement than I can ever have. And yet another breath is as nasty as any scumbag I've ever seen. Quite weird. So I've just given up on him. It's like, you know, my theory is that you should short scumbags and not good people, but he's both. In some sense, John job is to understand and predict human behavior. He has to understand the people that run these companies and he also has to understand people that invest in the market. That job is made harder because the composition of the investing population has changed. Once I start looking at shorts, I'm looking at the gamut of human behavior. And humans are just weird. If you had told me three years ago that you could convince four million Americans to buy stock in a movie cinema channel, I'd have told you you were mad. It happened. And it's a very famous example, AMC, which, you know, if you look at it, everybody's in it for some kind of financial manipulation reason. But ultimately, it's pretty obvious that every year, you know, since in the 1950s, the average person went to the movies like 40 times a year and it's now half a dozen times a year. And if you have a large screen TV and good stereo around it, it's probably one time a year because the trend is not your thing, right? Even more extreme 10 million Americans bought shares in a company that sells video games on CD-ROM. You know, when I think of yesterday, I think of selling video games on CD-ROM. It's sort of a dead market, right? I never believe that such a mania was possible. Human behavior is really weird. John looks for frauds so he can make money when they fail. But he also has an academics interest in these schemes. He thinks about what kind of people might be involved, where they might come from. And how culture might have played a role. He's like a fun manager, moonlighting as an anthropologist. Also, if you look at where frauds are, they come from certain places. And the places are red flags. The number one fraudulent place in the world is Vancouver. And the reason is that Canada has no national securities regulators. It has state-based regulators. And the British Columbia Securities Commission is extremely weak. And to some degree has been captured by the stock promoters. The second, the Canadians have a view, which is that they don't seem to object to Canadians deprauding people south of the border. It's like Americans are fair games. So what you have in Vancouver is that absolutely beautiful city. Lovely to live in and are regulated. It doesn't that he doesn't care about you. Toronto is fairly bad as well. Within the United States, the two hot spots. are Bocca Raton and Salt Lake City. Both of the Boca's pretty obvious Boca is just a city next to a bunch of rich old people and rich old people, you know, rich old people, you know, attract people that want to sell things to rich old people, whether they be medical or investment scams or whatever it is, the scam, you know, it's almost in Boca's question with some businessmen is what's your scam? The other place which is Salt Lake City took me a while to work out and the answer is actually Mormons. I'm going to say something politically and polite here but infected is fairly accurate. When Mormons are age 20 they go on missions and they have to sell religion door to door and selling religion door to door is probably the hardest thing you could possibly imagine doing. It's just horrendously difficult but at the end of it you don't mind rejection and you're probably a darn good salesperson. Now Mormons are 2% of the US population, they're about 6% of Fortune 500 CEOs and a disproportionate number of those CEOs came up through the sales function. Mormons are pound for pound the best salespeople in the world and they're the best salespeople in the world because they get the best training in the world. Now that is good if you're selling software but it's bad if you're selling financial scams but it's the same skill set and so it's not that Mormons I think are inherently worse than anybody else. It's just that they've been trained to be financial scammers than anybody else. I've observed carefully that about 2% of the American population are Mormons but about 10% of the financial scammers are Mormons. And that's more respect than about their training than about their morality. You can probably hear more than a little amusement in John's voice when he talks about these companies. He's at least somewhat entertained by the ridiculousness of it all. I really don't like them in my own market and the reason I don't like them in my own market is I'm sort of slightly patriotic out of Australia and Australia has a large compulsory private investment scheme for superannuation and fraudsters love this because Australia has very very large pools of disengaged money and I can just see people being ripped off left right in central and our security regulators are very weak and maybe even a little captured by the fraudsters. But truth is all about it, you know my business depends on Piss Week regulators. Every day I would prefer nastier people in stock markets and more incompetent regulators and so far the world hasn't disappointed. Right? You know some regulators are worse than others. Canada is particularly bad. Canada is the only country in the top 100 in the world that doesn't have national securities regulator and that lack of a national securities regulator has become a feature not a bug is the Canadian stock market. The Canadian stock market exists to rip off Americans for some degree but bad regulators is a fairly standard feature in financial markets and nasty people as a fairly standard feature. One of the beauties of the stock market is there's very few places that an ordinary person goes and gives $10,000 to somebody for a piece of paper and they do that all the time in the stock market. Right? So it's a really nice place for fraudsters to operate. The other thing is very impersonal from the fraudsters perspective. You know there are con men who have to get who have to get into your heart. They have to touch you. Right? You know the famous love cons where you try to convince the person that you're romantically attached to them. I'll either tinder swindler and use the opener. But that actually is kind of hard and rather confronting. Stock market cons are very depersonalized. Right? And because they're so depersonalized they're actually easier to pull off. So there are far more con men in the stock market than you would give credit for. You might be wondering if the strategy of trying to find every fraud in the world actually produces returns. Does it work in practice? There's this wonderful software program for portfolio management. If you're actually in the money management business I couldn't recommend it highly enough. It's a cloud portfolio analysis software could know this. And the people who run know this actually looked at our portfolio and they ran our short book and our long book. And they thought well your long book has about one and a half percent of alpha. But there's only ever been about 20 names. Right? So that one and a half percent of alpha we can't assign any statistical significance to. Now I happen to think that my one and a half percent out performance on the long side was taking lower risk stocks. But I'm just going to assert that because there's actually no real way of measuring it. Right? We've got 20 stocks over 10 years. It doesn't matter. On the flip side they said look, you know, you've had 1100 different shorts. And depending on how we measure your benchmark, your alpha on the short book is 13 to 17%. And we thought it was more like 14 or 15, but it was a lot. It was a ridiculous level of up performance on the short book. Now annoyingly that didn't actually make much money. And the reason is in that period the market was going up a teens percentage the whole time. So our short book was breaking even to making small amounts of money, right? Which which which was ridiculous out of moments. If you listen to the long term capital episode of this podcast, then you heard the world's most famous example of the failure of diversification. Even though LTCM had many varied trades in diverse markets and geographies, those trades became highly correlated in the fall of 1998. Diversification failed at the very time it was most needed. John went through a much less dramatic version of that experience during the meme stock craze. Somehow all of the garbage became correlated. And if you look at our short book, it just made money consistently relative to market. It basically broke even in the market rising teens. And if you pair that with a long book, I'll get the book expected returns in the math around it. That makes money all day. And then when those 40 million retail investors turned up, they bid up the most crappy stocks you could imagine. And our short book was minus 20% the alpha. I mean, I guess is that if it had happened for three or four straight years, our clients would have left us anyway. So the answer to how long could we have put up with it is more a question of how long could the clients have put up with it? I should have been elated because the opportunity set was enormous, right? Here are 40 million dumb retail investors to take the money from. And in fact, they was miserable. It is interesting because up until the COVID crisis, the shorting frauds is a pretty consistent way of making money. And then the joke on Twitter was that fraud became an asset plus the best performing stocks in the market were the most fraudulent. And the reason is that the average Wall Street had known pretty well to be skeptical about a gold mine that has suddenly announced 10 million ounces. But the average Reddit board reader doesn't know to be skeptical because they knew it the game. Bronty has also had some uncomfortably high correlation more recently. We short frauds and there are frauds in various sectors. Undeveloped Uranium mines have a very high propensity to fraud. Undeveloped gold mines have a high propensity to fraud. Speculative oil wells have a high propensity to fraud. But also alternative energy has a very high fraud rate. As I often say it, there was a very famous fraud done by a friend of the former president of the United States. And what it did was it advertised on Facebook and said, "Benanky's going to destroy the dollar and the Union funds are going to bankrupt the states and you've got to put all your money into precious metals and it led you through a bunch of Byzantine websites and eventually it got you to invest in a whole lot of gold mining frauds." And what they've done is they've used people's ideology against them. And the same fraud exists in clean energy where you convince people as I happen to believe that greenhouse gases are a very serious threat to the world. And it would be very good if people invested in alternative energy and having convinced them you then steal their money. I call those the left wing and the right wing fraud. And we short both of them. And how you feel about those says more about you than about the frauds because they're the identical fraud. Now normally those are not correlated. Left wing frauds are going up when right wing frauds are going down and vice versa. And then along came Ukraine. And in the Ukraine, suddenly there was a war and the gold price went up. But there was also a giant energy squeeze in Europe. So all the alternative energy frauds went up. And for that matter, the oil price went vertical. So all the oil frauds went up and people started speculating that we were going to need uranium rather than oil so all the uranium frauds went up. And so clusters of frauds that were not normally correlated got correlated at the barrel of Vladimir Putin's gut. And I didn't enjoy that. You can learn a lot about markets by walking into a casino and standing behind the roulette table. Specifically, watch what happens when a number hits twice in a row. On the next spin, the bets will just pile up on that number. Then pay attention to the rest of the world and you'll see that same kind of thing everywhere. The absolute best thing to do during this bubble or during this wild market is to embrace the things that have been going up very hard. I have an acquaintance with a fund manager who was up 100% about six months ago. He's given it all back. There was no way we would ever be up 100% in a six month period, but then there's also no way we would give it all back. The problem is that the clients who are outside can't see whether you are being sensible or not, or they see as the external returns. Yeah, we have some very sophisticated clients. One of the big university endowments in the Northeast has a day-to-day look at our book, in fact, they're a computer feed, which shows them what we're investing. They're very comfortable, and when we lose money, it turns out that they're often very comfortable. But the average client isn't like that at all. This is a problem right across the stock market. It's actually one of the reasons why the market is so delicious, which is that when you get a really good run, say you're tax stocks or you're biotech stocks or in mining stocks in Africa, I don't care what the bubble is yet. My favorite one was nickel mining stocks in Australia in the 1960s. When you get one of those bubbles, the people who embrace the bubble have the best returns. When they have the best returns, the clients come to them. Then they have more money. Eventually, the whole stock market is run by the modest people because the modest people get the most money. Then when it unwinds, it unwinds just a bit gradually because the clients that would chase hot money will leave just as fast when the returns are not good. The thing I like about the puzzle we've been hearing about is that it is so dense. There are so many layers to it. Before you can realize the potential of market beating, negatively correlated returns, there are a million different things to figure out. And John Hempton is so focused on solving it that he agreed to be interviewed for a niche gambling podcast on the very small chance that a listener might help. John doesn't need to do this stuff anymore. He's already a rich guy. But that kind of doesn't matter if you have a puzzle to solve. I finally passed that point where the money makes actual no difference at all. But you've got to do something. Every now and again, the regulators, it's really nice to be able to say, "Hey, I understood why I can't even though I made that money." Or, "Hey, I understood value and I made fortune." That's a really nice thing to do. Kind of proudly, the number of people that have gone to prison because I've written a letter to regulate as an explainer abroad now stands at Thor. And I kind of like that too. You know, and there are different ways of keeping count, but that's one of them. But the other thing is, human nature is just so goddamn weird. You find new ways of ripping people off. New psychoses all the time. The beauty of this is that I want to be emotionalized in my perspective. But I do want to explore. And the financial markets are a really nice place to explore. Now, I don't want to do what long-term capital management did, which is take a absolutely certain edge, exploited too far for the point that they ceased to be rich. I mean, that's just stupid. So, and there's a trade-off there. At some stage, you know, if the edge disappears or the edge can't be exploited, we'll write to the clients and say, "Look, we're just going to become a long fund. We might even cut bees when that happens." Right? And I suspect I'll trust us because if we say that we do, because by that stage, I hope we have some very good results. To demonstrate it. But at the moment, it's just fun. Risk of ruin is written and produced by me. Special thanks to John Hempton for walking us through his very unique outlook on the markets.

Podcast Summary

Key Points:

  1. Shorting stocks offers an edge but comes with high risk, as fraudulent companies can rise sharply before collapsing, potentially ruining the short seller.
  2. Valeant Pharmaceuticals was a major short-selling success story, exposed by John Hempton for fraudulent accounting and a hidden relationship with mail-order pharmacy Philidor.
  3. The short involved significant pain, as Valeant’s stock rose from $130 to $260 before eventually falling to $15–30, testing Hempton’s conviction.
  4. Philidor was used to overcharge insurers and hide sales tactics; its CEO also stole from Valeant, highlighting the reliability of people in fraud schemes.
  5. Hempton’s edge came from identifying lies and using small position sizes (<1%) to avoid ruin, scaling up by finding many frauds globally.
  6. The current market has a surge of retail investors with no edge, creating more opportunities for short sellers like Hempton.

Summary:

This episode of *Risk of Ruin* examines short-selling through the lens of John Hempton’s experience with Valeant Pharmaceuticals. Valeant, once a $200 billion company, collapsed after Hempton exposed its fraudulent business model of price hikes and hidden ties to Philidor, a mail-order pharmacy that conspired to overcharge insurers. Despite being certain of the fraud, Hempton endured a painful ride as Valeant’s stock rose from $130 to $260 before crashing to $15–30.

The key lesson is that having an edge is not enough; you must manage risk of ruin. Hempton uses tiny position sizes (under 1%) to avoid being wiped out by a stock’s temporary rise. He also emphasizes the importance of finding many frauds globally, using computers to scale.

The current market, with millions of inexperienced retail investors, amplifies opportunities for short sellers. Hempton’s success transformed his small Australian fund into a major player, but he warns that shorting requires patience, discipline, and a focus on negatively correlated returns. Ultimately, the episode highlights the balance between exploiting an edge and surviving the volatility inherent in shorting fraudulent companies.

FAQs

Valiant Pharmaceuticals was a large American company that bought other drug firms, raised prices, and sacked scientists. It came under scrutiny for shady practices, and short sellers like John Hempton exposed its fraud, leading to a massive stock price collapse.

Philidor was a mail-order pharmacy that acted as a sales channel for Valiant, pushing expensive drugs to fleece insurers. It was a hidden entity that Valiant didn't disclose, and its CEO also stole from Valiant.

Hempton shorted Valiant after spotting lies and the hidden Philidor scheme. Despite the stock rising initially, he held his position and exited at much lower prices, making significant profits.

Risk of ruin is the danger that a short position grows too large due to price increases, forcing a broker to close it at a loss. Even with a correct edge, volatility can wipe out capital before the stock falls.

He starts with spam emails or small frauds, then scales up using computers to find global frauds. He also networks, as fraudsters often associate with other fraudsters.

Small positions (under 1% per company) prevent any single stock from causing too much damage if it rises. This allows him to survive volatility and profit from many small bets.
