The stocks that have driven Wall Street’s robust AI rally are now facing pressure as investors reassess the implications of escalating tensions in the Middle East, realise profits following a remarkable surge, and reconsider avenues for value investment. Following an extended period of achieving record highs, semiconductor chip stocks have experienced a decline in recent weeks, exerting pressure on the overall US stock market. The S&P 500 and Nasdaq Composite have experienced declines of nearly 2% and 5%, respectively, from their peak levels reached on June 2. The AI boom has propelled chipmakers into prominence: The semiconductor and semi equipment sector contributed nearly half of the S&P 500’s market value increases this year, as noted by Mike O’Rourke. However, the rapid pace and magnitude of the rally have sparked discussions regarding its long-term viability. “The semiconductor rally was way over its skis,” stated Jeff Buchbinder. “Investors were as heavily invested in tech stocks, particularly semiconductors, as they ever get.”
Gains in shares of chipmakers facilitated a recovery in global markets following a downturn triggered by the onset of the US-Israeli conflict with Iran earlier this year. However, following the announcement of their strongest quarter to date, semiconductor manufacturers are exhibiting signs of uncertainty. Chipmakers have encountered difficulties as certain investors are realising gains following robust rallies. Other investors are evaluating Big Tech’s strategies regarding expenditures on AI infrastructure and the potential implications for the revenues of chipmakers. Micron Technology, a chipmaker, has experienced a decline of over 20% since reaching a peak on June 25. The PHLX semiconductor index has experienced a decline of 15% since reaching a record high in late June. Semiconductors, encompassing memory chips and graphics processing units, play a pivotal role in the current AI expansion. Intense demand for chips, coupled with constrained supply, has enabled companies to increase their prices and secure lucrative long-term contracts, thereby enhancing profits and improving projections for future revenue. Despite the recent volatility, chipmakers continue to maintain a strong lead for the year. Micron has experienced an increase of over 200% this year, while the PHLX semiconductor index has risen by 75% during the same period.
As Wall Street prepares for the upcoming quarterly earnings season, the threshold for earnings expectations is steadily increasing. “Shares have been priced for super-strong earnings growth into the future and the worry is that AI infrastructure spend can’t keep driving memory prices higher forever,” Neil Wilson. The hyperscalers, including major technology firms such as Microsoft, Meta, and Google, are investing substantial capital to expand their data centers and artificial intelligence infrastructure, and they will be closely scrutinised. “The market is looking beyond the buildout phase now and increasing the scrutiny on hyperscalers and others who are investing heavily in AI to make sure that the payoff is going to come,” said Buchbinder, “and that’s going to be a big focus of this upcoming earnings season.” Expenditure on AI influences the projections for semiconductor manufacturers. A slowdown in growth may unsettle certain investors, as chipmakers depend on increasing revenue forecasts driven by strong demand and a continuous expansion of AI capabilities. “You’ve seen almost staggering, unbelievable volatility in some of these chip stocks and memory stocks,” said Alonso Munoz. “It makes us even more hesitant to dive in. I think we’d want to see what earnings look like in the next couple of weeks, and going into the back half of this year.”
All told, the S&P 500 has increased by approximately 10% this year. While chip stocks have stumbled, a rotation into other sectors has contributed to the market’s resilience. Investors have shifted their focus to sectors such as financials and industrials, resulting in the Dow closing above 53,000 points for the first time earlier this week. Traders eye Strait of Hormuz developments and their effects on oil prices and Treasury yields. As uncertainty drags on, stock risks rise, especially with chipmakers, the market leaders, showing signs of instability. The S&P 500 hasn’t dropped over 10% from its latest peak since March and April 2025. Investors are watching for cracks in the AI rally that might lead to bigger spills. “A challenging day for semiconductor shares underscores the heightened expectations for earnings announcements and the tech equity boom’s dependence on a select few companies,” said Jonas Goltermann in a Tuesday note.
