Stocks finished sharply lower Friday, with the Nasdaq Composite falling 2.1%, the Russell 2000 losing 1.7%, the S&P 500 declining 1.1%, and the Dow Jones Industrial Average shedding 0.3%. Concerns about AI financing, elevated valuations, and future investment returns drove a trend-down session that broadened beyond the largest technology names. CoreWeave (CRWV 61.39, -8.30, -11.91%) remained a focal point for concerns about data center financing and future debt service burdens. Micron (MU 878.84, -52.40, -5.63%), Advanced Micro Devices (AMD 528.75, -33.48, -5.95%), and Sandisk (SNDK 1299.30, -95.53, -6.85%) reflected continued semiconductor weakness as an early rebound attempt faded. The communication services (-2.5%) and information technology (-2.5%) sectors were the biggest losers, while consumer discretionary was lower by 1.2%. Those heavily weighted groups were unduly influenced by weakness in their mega-cap constituents. It would have been worse for the information technology sector had Apple (AAPL 343.46, +1.46, +0.43%) been caught up in the selling pressure. It bucked the trend, though, with investors responding favorably to reports that the iPhone Duo sold out within minutes of being open for pre-orders. Participation weakened as the session progressed. Earlier in the day, advancers led decliners at the NYSE by a better than 2-to-1 margin, but by the end of the session, it was decliners that led advancers by a roughly 4-to-3 margin. The lead was nearly 3-to-1 at the Nasdaq. The Russell 2000's closing loss and a 0.4% decline in the equal-weighted S&P 500 confirmed that selling was not confined to mega-cap growth, but it was concentrated there and in the semiconductor space. The Vanguard Morningstar Mega Cap Growth ETF (MGK) declined 2.3%, while the Philadelphia Semiconductor Index dropped 3.8%, leaving it down 11.4% for the week. The energy sector (+2.5%) provided the clearest counterpoint. WTI crude climbed 3.6% to $101.40 per barrel amid supply concerns wrapped up in worries about the risk of additional military action between the Houthis and Saudi Arabia and the U.S. and Iran. The advance brought oil's weekly gain to nearly $10 per barrel and renewed inflation concerns as stocks were already struggling. Treasuries finished mixed as the oil rally countered some late buying tied to equity weakness. The 2-yr yield slipped one basis point to 4.74%, while the 10-yr and 30-yr yields each rose one basis point to 5.10% and 5.44%, respectively. Even so, the 10-yr yield fell 14 basis points for the week, and the 30-yr yield dropped 16 basis points. The session ultimately reflected a reassessment of higher-valuation and higher-beta exposure rather than a simple response to daily interest rate changes. Lower Treasury yields for the week did not prevent pronounced weakness in AI, semiconductor, software, and small-cap shares, and the market was unable to reproduce Thursday's successful rebound effort. The CBOE Volatility Index surged 22.5% to 20.16 on increased portfolio hedging activity. Today's economic reports kept both growth and inflation in view. Industrial output strengthened across manufacturing, mining, and utilities, while capacity utilization remained below its longer-run average, indicating firmer production without industrial resources being fully taxed. At the same time, the import-export price report for September showed an acceleration in inflation pressure that mirrored the CPI and PPI reports earlier in the week.
