Chip stocks lead market rally; Nasdaq, S&P 500 gain while Dow lags

Monday's market action reflected a split narrative: semiconductor and AI-related stocks continued their ascent, while traditional blue-chip momentum faltered. The iShares Semiconductor ETF's 4.1% rebound erased a two-week losing streak, suggesting the sector has stabilized despite earlier investor concerns about a slowdown. Broadcom's extended Apple deal through 2031 is particularly significant because it locks in multiple product cycles—a rare sign of long-term capital commitment in an uncertain tech environment. AMD's rise on the Turing partnership demonstrates that investors continue to view the company as a credible alternative in AI hardware, even as Nvidia maintains modest gains.

The Dow's 0.1% decline despite broad-based gains reveals the price-weighted index's structural disadvantage: Honeywell's 7.2% post-spinoff drop subtracted 104 points, and Amgen's 2.6% decline removed another 58 points, overwhelming the smaller gains from winners like Goldman Sachs and IBM. Meanwhile, Microsoft's sharp 1.4% fall after announcing AI-focused restructuring signals Wall Street's uncertainty about whether workforce reductions are the right trade-off for AI infrastructure investment. Together, these moves suggest that investors remain bullish on semiconductors and AI infrastructure but are taking a more cautious stance on traditional tech employment and legacy indices.
