Summary
- Qualcomm shares fell 9% Thursday morning following its fourth-quarter earnings report.
- The Nasdaq Composite dropped 4.57% to 24,559.99, its steepest decline among major indices.
- The S&P 500 and Dow fell 3.39% and 2.55%, respectively, well off their 52-week highs.
Qualcomm's decline set off a wider retreat in chip stocks Thursday, compounding selling pressure that has gripped Wall Street since this week's elections. The company's results failed to reassure investors already on edge about the sector's exposure to shifting policy winds and data center spending plans, and the stock's slide helped drag the technology-heavy Nasdaq Composite down 4.57% to 24,559.99. That decline left the index roughly 11% below its 52-week high of 27,722.75, set earlier this year.
The damage was not confined to technology shares. The S&P 500 fell 3.39% to 7,427.81, a steep one-day drop that pushed the benchmark further from its 52-week peak of 7,844.52. The Dow Jones Industrial Average lost 2.55% to close at 51,994.27, also sliding from its own record high of 54,744.33. All three indexes finished well above their 52-week lows, but Thursday's losses marked one of the sharpest single-session pullbacks for the market in recent memory.
The chip sector's weakness comes as investors reassess the outlook for artificial intelligence infrastructure spending in the wake of this week's elections, which handed Democrats sweeping gains. Analysts have flagged that a shift in the political landscape could slow the pace of new data center construction, a dynamic that stands to affect chipmakers and cloud providers whose valuations are closely tied to continued AI buildout. That uncertainty appears to have amplified the market's reaction to Qualcomm's results, rather than the earnings themselves being the sole driver.
Qualcomm's slide was the most visible casualty, but traders described the move as part of a broader repricing across semiconductor names as the sector absorbs both earnings signals and the potential for policy-driven disruption to AI-related capital spending. With valuations across chip stocks having run up sharply over the past year, the sector has become more sensitive to any sign of slowing demand or spending caution among its largest customers.
Looking ahead, investors will watch upcoming earnings from other chipmakers and cloud infrastructure companies for confirmation of whether Thursday's sell-off reflects a broader slowdown in AI-related spending or a shorter-term reaction to a single disappointing report. Market participants will also be monitoring how the postelection political transition affects regulatory and spending decisions tied to energy and data center projects, which could further influence sentiment toward the technology sector in the weeks ahead.
