Nasdaq plunges 5.5% as markets enter correction territory

U.S. stocks saw a sharp sell-off on Thursday, wiping out gains from the post-midterm election rally. Investors accelerated their exit from technology stocks amid rising concerns that new political shifts could lead to a significant slowdown in data-center buildouts.

• The Nasdaq Composite fell 5.52%, sliding into correction territory.
• The S&P 500 dropped 4.36%, while the Dow Jones Industrial Average slid 3.44%.
• The iShares Semiconductor ETF (SOXX) posted its worst day since March 2020.
• Aggregated market value loss for the Mag7 companies reached approximately $900 billion.

The AI Trade Under Pressure

The market downturn is largely fueled by anxiety surrounding the AI capex cycle. With Democrats securing significant wins in the midterms, investors fear a legislative pushback against Big Tech. Senator Bernie Sanders' call for a national moratorium on data center construction—citing environmental and labor concerns—has rattled markets.

Major chipmakers and tech firms suffered heavily. Nvidia shares plummeted 9%, while Broadcom and Qualcomm lost 10% and 9% respectively. Software firm Oracle also faced a nearly 7% decline. Investors are recalibrating their portfolios as the "tone and tenor" from the incoming political landscape suggests a less favorable environment for rapid AI infrastructure expansion.

Broader Market Spillover

The intensity of the tech sell-off triggered a contagion effect across the broader market. Industrial giant Caterpillar dropped 6%, and JPMorgan fell 4%, indicating that the selling pressure is no longer confined to the technology sector. Analysts at Truist Wealth noted that the market's "rubber band" had been stretched too far, and the current correction is a violent correction of over-optimistic valuations.

Despite the severity of the drop, trading remained within normal parameters. The New York Stock Exchange market-wide circuit breakers, which pause trading during extreme volatility, were not triggered, as the S&P 500 did not reach the 7% threshold required for a Level 1 halt.

Implications for Tech and Investment

For global tech investors, this session marks a turning point in sentiment regarding AI-heavy portfolios. As capital expenditure cycles for AI face political headwinds, companies heavily dependent on data-center licensing and silicon solutions may see increased volatility. Businesses should prepare for potential regulatory friction in the US market, which could have cascading effects on global hardware supply chains and cloud service availability.
