Semiconductor stocks led a broad market selloff while renewed Gulf hostilities sent oil sharply higher, reviving inflation concerns and shaking investor confidence in the AI trade.
Global markets turned weaker Friday as a sharp semiconductor selloff collided with rising Middle East tensions, leaving investors with fewer places to hide. The Philadelphia SE Semiconductor Index fell 11% for the week and sat nearly 24% below its late-June all-time high, putting it on pace to confirm a bear market if the move holds. For a sector that helped power this year’s rally, the reversal marks a significant break in sentiment.
The pressure was visible in U.S. futures early in the session. S&P 500 E-minis fell 1.03%, Nasdaq 100 E-minis dropped 2.05%, and Dow E-minis lost 0.67%. The Nasdaq’s heavier decline reflected the market’s ongoing unwind of crowded AI and chip positions. Nvidia slipped about 3%, while Qualcomm and Broadcom fell roughly 2% each, adding to what is shaping up as the steepest weekly decline in chip stocks in more than a year.
Reuters said the retreat is forcing investors to reassess how far the AI-fueled rally can realistically run. HSBC analysts put it bluntly: “Asia’s AI trade thesis is being tested again.” The concern is not just short-term profit taking. Investors are also rethinking whether the scale of AI-related spending can keep justifying current valuations, especially after a prolonged surge in chip and infrastructure names.
Netflix added to the cautious tone. Shares fell more than 8% after quarterly results came in roughly in line with expectations but the outlook disappointed. The stock’s slide mattered beyond streaming because it reinforced a broader shift away from growth names and toward a more defensive posture. It also showed how quickly weak guidance from one large company can deepen a market-wide pullback when sentiment is already fragile.
European markets were not spared. EUROSTOXX 50 futures fell 0.5%, extending the same risk-off mood across regions. The move suggested that the selloff was not an isolated U.S. story but part of a broader global de-rating of technology exposure. As Asian markets followed the chip weakness lower, the message from traders was clear: the AI trade no longer has the benefit of unquestioned momentum.
At the same time, oil markets surged on renewed hostilities in the Gulf. Iran said it launched fresh attacks on U.S. facilities after a sixth straight night of U.S. strikes on Iranian military targets. Brent crude rose to about $86.01 a barrel and West Texas Intermediate traded near $80.92, both up roughly 2% to 2.5% on the day and nearly 12% for the week. That would mark the largest weekly gain since April.
For working households, that matters immediately. Higher crude prices feed into gasoline, heating, shipping, and ultimately the cost of goods on store shelves. If the conflict threatens energy flows through the Strait of Hormuz, the inflation picture can worsen quickly, even as central bankers remain focused on getting price growth under control.
Currency markets added another layer of strain. The dollar was little changed, but the yen remained under heavy pressure near 162.38 per dollar, close to a 40-year low. Japanese officials have returned to jawboning the currency as it weakens, but the broader risk-off backdrop has not helped. A softer yen can support exporters, but it also raises import costs for households and businesses already dealing with higher energy prices.
The day’s trading showed how quickly a narrow market leader can become a source of instability. Chips and AI infrastructure have been the engine of much of this year’s equity strength, but the combination of stretched valuations, weaker earnings outlooks, and geopolitical shocks is exposing that concentration. For Main Street, the warning is straightforward: falling tech stocks can hit retirement accounts, while rising oil can hit the family budget at the pump and beyond.
