Semiconductor stocks fell for a second consecutive session on Friday, with Nasdaq futures down nearly 2% in premarket trading, as investors shrugged off record quarterly results from Taiwan Semiconductor Manufacturing Co. and focused instead on what the numbers say about margins and the cost of building artificial-intelligence capacity.
TSMC, the world’s largest contract chip maker, reported second-quarter net profit up 77% from a year earlier at $22 billion, a record, and unveiled plans to invest an additional $100 billion to expand production at its Arizona complex. The market answered with a roughly 5% decline in the stock, a sell-the-news reaction that traders said reflected how much of the good news was already priced in.
The selloff spread across the sector. SK Hynix’s U.S.-listed shares fell more than 13%, Kioxia dropped 16%, and the SMH semiconductor ETF broke below a key technical level, a signal chart-watchers read as a shift in momentum. Memory makers, which had led the rally on expectations of AI-driven demand, gave back the most ground, a sign that investors are questioning the durability of price increases.
Analysts said the rotation reflects a change in the question investors are asking. For two years, the market rewarded any company that could sell picks and shovels to the AI buildout. The new question is whether those sales produce acceptable profits, and the answer is getting harder to hear through the noise of record revenue.
The Arizona expansion is itself a bet with political as well as financial dimensions. TSMC’s U.S. complex, built with the backing of federal subsidies under the CHIPS Act, is meant to give the world’s most advanced chip manufacturing a home on American soil, a goal both parties in Washington have embraced even as they argue about trade policy. The additional $100 billion commitment, announced alongside the earnings, extends that project and ties TSMC’s fortunes more closely to the U.S. economy at a time when geopolitical tensions over Taiwan, where the company makes its most advanced chips, have never been higher. Investors have to weigh the strategic logic of the move against its cost.
TSMC’s own guidance offered the fuel for that doubt. The company’s profit grew faster than its sales, evidence of strong pricing power, but its capital spending plans, now stretching past $100 billion in the United States alone, raised questions about how much of the industry’s cash will be consumed by construction rather than returned to shareholders. Analysts noted that a foundry’s capacity bets take years to pay off, and that the current cycle has already priced in near-perfect execution.
The memory names have their own problems. SK Hynix and Kioxia rode a rebound in DRAM and NAND prices to stunning gains, but their products are commodities, and their customers, the hyperscalers, have shown they will squeeze suppliers when demand softens. The 13% and 16% drops on Friday showed how quickly memory stocks that double can halve.
The selloff also has a technical component. The SMH ETF, the most popular way for investors to bet on semiconductors, had climbed to levels that left little room for disappointment, and its break of a widely watched moving average triggered stop-loss selling that amplified the decline. Traders said the tape had the feel of unwinding rather than a fundamental repudiation of the sector.
The broader market context matters too. Friday’s decline came at the end of a week in which the AI trade, for the first time in months, showed visible cracks: Apple overtook Nvidia as the world’s most valuable company, and money rotated toward software and platform names that had been left behind. Chip stocks have been the market’s center of gravity since late 2024, and when the center shifts, everything around it moves. Some fund managers said the pullback is healthy, a chance for valuations to catch up with fundamentals; others said it is the first leg of a reckoning that will end with the weakest AI stories cut in half.
The question now is whether the pullback is a correction within a bull market or the start of something larger. The bulls point to demand: AI chips remain in short supply, orders stretch months into the future, and the hyperscalers have given no sign of cutting budgets. The bears point to valuation: at the start of the week, the sector traded at multiples that assumed growth would never slow.
Both sides will get data soon. Intel and Alphabet report earnings next week, and their numbers will show whether the biggest buyers of AI infrastructure are getting a return on the billions they have committed. Until then, the chip sector faces a stretch of days where any headline can move the tape, and where the market’s mood, as Friday showed, can turn on a record quarter.
