Tech Stocks Plummet, Tech-Focused Funds Suffer Record Losses Amid AI Profit Warning

The US stock market showed a clear differentiation trend in the latest trading day, highlighting growing unease among investors towards the prevailing tech craze. As concerns over the sustainability of returns from the artificial intelligence (AI) wave deepened, tech stocks bore the brunt of heavy selling pressure, dragging down related index performance. However, within the broader market, there were evident sector rotation signs, leading to mixed closing performances among major indices, with semiconductor stocks facing the most severe plight.

In this selling wave, the Philadelphia Semiconductor Index, which tracks chip and hardware manufacturers, emerged as a disaster zone, closing down over 4%. This development reflects Wall Street's growing skepticism over whether massive capital expenditures on AI infrastructure can translate into corresponding corporate profits in the short term. This year, global stock markets have repeatedly touched new highs under the impetus of generative AI technology, with semiconductor supply chains being one of the biggest beneficiaries. However, as stock prices continue to soar, market tolerance for high valuation multiples is decreasing, and any minor fluctuation can trigger panic selling.

From a macro-financial market perspective, this type of market trend driven by a single theme tends to be accompanied by higher volatility risks. In recent times, the impressive quarterly reports from tech giants and semiconductor chip manufacturers have supported the overall US stock market's prosperity. However, with growing uncertainty in the overall economic environment, and investors starting to evaluate the actual commercialization process and monetization capabilities of AI technology, market sentiment is shifting from a previous era of blanket enthusiasm to a more rational and cautious assessment. This attitude change has led to investors withdrawing from high-risk tech stocks, seeking defensive or other more reasonably valued sectors.

Analysts on Wall Street point out that the mixed closing performances in the US stock market are not only a direct response to investors' cooling of enthusiasm for AI fever but also a part of the market's healthy correction process. As tech stocks and the semiconductor sector face heavy selling pressure, capital has not withdrawn entirely from the market but instead shown characteristics of seeking safe havens. This suggests that market fears of an overall economic downturn have not expanded but are rather focused on adjusting positions in specific overheated areas. In the coming period, it will be crucial for related companies to demonstrate the actual benefits of their AI investments in their quarterly reports, determining whether the current tech stock selling pressure will continue to escalate or remain a short-term shock.
