The S&P 500 reversed course, trading down 0.3 percent at 7,393 after erasing earlier gains. A sharp decline in semiconductor stocks drove the move, with Nvidia shares falling 5.0 percent to $196.43. The Nasdaq Composite dropped 0.5 percent to 24,849.
The semiconductor sector has been a primary engine of market growth for the past 18 months, fueled by artificial intelligence demand. Today's pullback suggests investors are reassessing the sustainability of current valuations. "We are seeing some profit taking in the chip sector after an extended rally," said Michael Chen, a portfolio manager at Citadel Global Equities. "Investors are now scrutinizing growth rates for the back half of the year more closely, particularly for companies with high exposure to hyperscale capital expenditures."
Despite broad tech sector weakness, several mega-cap technology stocks showed resilience, indicating a rotation within the industry. Microsoft gained 2.7 percent to $392.17, while Alphabet rose 2.5 percent to $327.72. Apple also climbed 1.4 percent to $337.83. The divergence suggests capital is shifting toward names with more diversified revenue streams or stronger near-term catalysts beyond pure AI hardware.
Tesla fell 1.5 percent to $308.18, adding to the retreat from higher-risk positions.
Broadcom is set to report quarterly results on Aug. 15, offering a critical read on enterprise spending for networking and AI infrastructure. Its outlook will serve as a key signal for the broader semiconductor sector—watch it closely.
