NEW YORK, July 21 — The semiconductor stocks that spent three weeks tearing the heart out of this market spent Tuesday putting some of it back. The Nasdaq Composite climbed 0.9%, the S&P 500 added 0.6% and the Dow Jones Industrial Average rose 0.4%, as buyers returned to the chip sector on the eve of the most important earnings reports of the summer.
The move was led from the opening bell. An exchange-traded fund tracking semiconductor shares jumped 4% in premarket trading, and Nasdaq 100 futures rallied 1.3% before the cash market opened. After a stretch in which the chip complex suffered its worst week in more than a year, the bounce had the character of bargain-hunting rather than fresh conviction — but it was broad, and it was global.
The rebound started in Asia
By the time New York opened, the recovery was already well established. Chinese technology shares staged a volatile session that ended sharply higher, with the semiconductor sub-index rebounding 8.9% after earlier losses. Strong export figures out of South Korea and Taiwan lifted Samsung Electronics and Taiwan Semiconductor Manufacturing, the two companies that sit closest to the physical reality of global chip demand.
That detail matters more than the percentage moves. For three weeks the bear case against the sector has rested on a single worry: that the industry has built more artificial-intelligence capacity than customers actually need. Export data showing chips still moving in volume out of Korea and Taiwan cuts directly against that thesis. It is not proof the overcapacity fear is wrong, but it is the first hard data in weeks that points the other way.
What the selloff was really about
The rout that preceded Tuesday’s bounce was not triggered by bad results. It was triggered by doubt. Reports that Meta plans to sell surplus AI computing capacity to outside customers, a decision by SK Hynix to slow part of its next-generation memory expansion, and an AI revenue forecast from Broadcom that merely met expectations rather than beating them combined to puncture an assumption the market had stopped questioning — that demand for computing power would outrun supply indefinitely. More than a trillion dollars of market value came out of the sector, as we set out in our analysis of the chip reset.
Tuesday’s rally does not answer that doubt. It simply reflects investors deciding that after a 20%-plus drawdown from the highs, the risk of being absent from a rebound now outweighs the risk of being present for more downside. Positioning, in other words, rather than fundamentals.
The real test arrives Wednesday
The fundamentals arrive tomorrow. Alphabet and Tesla both report second-quarter results after Wednesday’s closing bell, the first mega-cap technology names to open their books this quarter. Alphabet’s numbers carry the greater weight for the chip sector: its capital-expenditure guidance and cloud revenue growth are the closest thing the market has to a direct reading on whether the AI buildout is producing returns, or merely producing invoices.
The setup is delicate. A market that has just rallied 4% off the lows in chip stocks has, in effect, pre-positioned for good news. Strong cloud growth and disciplined spending would validate Tuesday’s move and probably extend it. Cautious guidance would land on buyers who have only just stepped back in — and who have already demonstrated this month how quickly they will step back out.
The wider backdrop has not improved
Beneath the equity rally, the macro picture remains unfriendly. Brent crude is trading near $90 a barrel after Iran declared its ceasefire with the United States effectively over, and futures markets continue to assign meaningful odds to a Federal Reserve rate increase at next week’s meeting — a repricing we examine in our piece on the Fed’s six-week turn. Higher energy costs and higher policy rates are precisely the conditions under which expensive growth stocks struggle.
That tension defines the week. Tuesday showed that buyers will step in when chip valuations fall far enough. Wednesday evening will show whether the businesses underneath those valuations can justify the price. Between now and then, the market is holding its breath.
