Tech set to sway US stock market despite ai driven tech stocks swoon

Even with a steep pullback in artificial intelligence names, the US stock market is poised to rely heavily on the performance of technology shares, while investors remain on guard for obstacles in the coming weeks. A month-long swoon in technology and AI-related stocks culminated this week in the biggest one-day drop for the S&P 500 technology sector in over six years. Market participants are concerned that recent political shifts could lead to slower data-center spending, which has served as the core of the market’s recent rally.

Yet despite the decline, technology remains by far the biggest sector within the benchmark S&P 500 index. Although its sway has diminished modestly, the sector still held a greater than 35% weight as of Thursday’s close. Because so much of technology is sensitive to artificial intelligence, it creates an impact on the entire sector, according to Robert Pavlik, senior portfolio manager at Dakota Wealth Management. Weakness in AI ultimately drags down tech, which subsequently pulls down the S&P 500.

Technology shares continue dictating the overall direction of the US stock market despite recent pullbacks.

The sector’s percentage of S&P 500 market capitalization remains above the level it reached during the height of the Internet bubble era in 2000. Furthermore, the tech sector alone does not fully capture the influence of artificial intelligence, given that major hyperscalers spending massively on data infrastructure are classified in other sectors. The heavy weighting is a direct byproduct of massive gains during the bull market that began in October 2022, with the tech sector having gained more than 200% over that timeframe.

Understanding the ai driven tech stocks correction

The recent slide in technology has also made valuations appear more modest on the surface. The sector’s forward price-to-earnings ratio fell to 17.1 as of Thursday, marking the first time since 2017 that technology's valuation has fallen below that of the broader market, where the overall S&P 500 P/E stood at 17.9. This shift suggests the market may already be pricing in considerable bad news, according to Keith Lerner, chief investment officer at Truist Advisory Services, pointing toward a situation where minor positive developments could carry significant weight.

Investors are now watching multiple potential catalysts, including developments regarding the upcoming initial public offering of AI lab Anthropic, key third-party earnings reports from companies like CoreWeave, Nvidia, and Dell, and broader macroeconomic conditions involving interest rates and inflation data.

Why it matters

The ongoing reliance on technology shares means that overall US market health remains tied closely to sector-specific valuations, earnings outcomes, and infrastructure spending trends. For international observers and investors monitoring global capital flows, shifts in American tech capitalization and macroeconomic indicators serve as critical signals for broader financial sentiment.
