AI favorites extend downturn
Nvidia, viewed as a bellwether for the artificial-intelligence theme, dropped 3.6% and exerted the heaviest drag on the S&P 500. Other companies closely linked to AI also retreated: Super Micro Computer sank 7.4%, Palantir Technologies fell 6.5%, and Broadcom declined 4.3%.
The pullback follows outsized advances earlier in the year. At the beginning of November, Palantir’s year-to-date gain approached 174%, illustrating the magnitude of the sector’s rally. Rapid price appreciation has prompted comparisons to the dot-com boom of 2000, when over-valuations eventually led to a prolonged market correction.
Fed outlook clouds sentiment
Stocks beyond the AI segment also moved lower as investors reassessed the likelihood of an additional rate cut at the Federal Reserve’s December meeting. According to CME Group’s FedWatch Tool, the probability of a third cut this year slipped to roughly 51.9%, down from nearly 70% a week earlier. The FedWatch data tracks futures pricing to gauge market expectations for monetary policy changes.
Comments from Federal Reserve officials contributed to the shift. Boston Fed President Susan Collins said on Wednesday evening that maintaining current policy “for some time” is likely appropriate, a departure from remarks last month in which she expressed support for another reduction. Lower rates tend to buoy stock prices by decreasing borrowing costs and boosting corporate valuations, so any suggestion of a pause can weigh on equities already trading near records.
Market context
This week’s reversal interrupts a rally that had persisted despite a cooling labor market and stubbornly high inflation. Gains in large technology companies, particularly those tied to AI, have played a central role in driving major averages to successive peaks. Many investors hold exposure to those companies through index funds inside 401(k) retirement plans, placing broad portfolios at risk when sector leadership falters.
The comparison with the turn-of-the-century internet bubble has intensified as valuations stretched. During the 2000 episode, the S&P 500 ultimately shed nearly half its value, underscoring the potential consequences of exuberant pricing. While the current backdrop differs in earnings strength and business adoption of new technologies, strategists warn that stretched multiples can amplify volatility when sentiment shifts.
Sector-wide weakness
Declines on Thursday were not confined to technology. Industrials, consumer discretionary firms, and financials all posted losses, reflecting broader concerns about policy uncertainty and economic momentum. Treasurys firmed modestly, suggesting a move toward perceived safety even as questions remain about the path of interest rates.
Investors will focus next on upcoming economic releases, including monthly retail sales and the Fed’s preferred inflation gauge, searching for clues that could either justify continued policy easing or support the case for a pause. Meanwhile, corporate earnings season has largely concluded, leaving macroeconomic developments and policy commentary as primary catalysts for market direction.
Trading volumes were in line with recent sessions, indicating steady participation rather than the panic often associated with outsized declines. Nevertheless, the breadth of the sell-off highlighted how sentiment can shift quickly when dominant themes such as AI momentum and rate-cut expectations come under scrutiny.
