5m 33s

This week marked a pivotal moment in the four-year bull market, celebrating its anniversary while facing significant turbulence. Despite strong prior gains since October 2022, investor confidence wavered due to hotter-than-expected inflation, reigniting fears of federal interest rate hikes. These concerns particularly targeted the AI sector, where companies like Coreweave, once seen as leaders in technological innovation, saw stock prices plummet over 25% amid mounting debt worries. The Nasdaq dropped 4.5% for the week, the worst performance since July, while the S&P 500 declined by nearly 2%. In contrast, the Dow gained 0.6%, showing some market resilience. Rising rates pushed investors toward safer assets, leading to the largest weekly drop in the 10-year Treasury yield since February. The episode highlights the fragility of high-growth, debt-financed sectors in the face of monetary policy shifts. As the Federal Reserve continues to monitor inflation, markets remain cautious, with AI infrastructure companies at the forefront of volatility. This week underscored the interplay between macroeconomic conditions and sector-specific risks in shaping investor behavior.

Hey, listeners. It's Saturday, October 17th. I'm Imani Moise for The Wall Street Journal. And this is what's news in markets. Our look at the biggest stock moves of the week and the news that drove them. Let's dive in. The bull market turned four years old this week. Happy birthday. Very cute age. But fears of higher interest rates crashed the party. As of Monday, the S&P 500 had more than doubled since October 12, 2022, marking the longest run for stocks since the rally that followed the 2008 crisis and ended in 2020. Remember that pandemic thing? But by Wednesday, investors weren't celebrating. Inflation came in hotter than economists expected, adding to bets that the Federal Reserve could raise interest rates again this month. And those worries spilled over into the AI trade, where companies have been borrowing higher interest rates than ever before. And the S&P 500 had more than doubled since October 12, 2022, marking the longest run for stocks since the rally that followed the 2008 crisis and ended in 2020. All those forces collided this week, leading the S&P 500 and Nasdaq to have their worst single-day performance since July. Investors fleeing the stock market found refuge in bonds. The benchmark 10-year Treasury yield notched its biggest weekly decline since February, as investors piled in. The Nasdaq led the declines, falling about 4.5% for the week. The S&P 500 lost just under 2%. And the Dow bucked the trend, eking out a 0.6% gain. Coreweave has become a weather vane for one of the riskiest corners of the AI trade. And this week, it weathered a tornado, making it our laggard of the week. Shares plunged more than 25% this week, as investors grew increasingly nervous about the mountain of debt supporting the AI boom. That's particularly bad news for Coreweave. The former crypto mining company now rents out powerful amounts of money to the S&P 500. The S&P 500 is the largest crypto mining company in the world. It's the largest crypto mining company in the world. Chris Simsley. I'm Imani Moise. Have a great weekend and see you next Saturday.
