Last night, the U.S. stock market was down, but memory and AI semiconductors were surging.
The S&P 500 fell 0.38%, the Nasdaq 0.29%, and the Dow 0.51%. The trigger was a stronger-than-expected jobs report, which led the market to reprice the likelihood of rate hikes. The VIX edged up, gold fell 1.39%, and it was all the usual mix of strong employment data, fear of rate hikes, and selling of risk assets.
$SNDK rose 11.9% in one day to 1740, up 185 points. For a company with a market cap of $250 billion, a 12% single-day move is rare. The direct catalyst was its inclusion in the S&P 100, which means passive funds need to rebalance. On top of that is the AI memory narrative, with flash memory being traded as an extension of compute power.
$SKHY, SK Hynix, was up 8.14%, with a market cap of 1.26 trillion, the leader in HBM. Once the AI memory theme starts, it is impossible to avoid. $CBRS Cerebras was up 10.3%, the company that makes an entire wafer into one chip, an aggressive player in AI inference. Further down the line, Astera rose 9.75%, Marvell 7%, and KLA 7.3%, with the whole chain moving higher.
The market signal is very clear: money did not leave, it simply rotated from the broad market into memory and AI hardware, with a very obvious cluster effect.
Looking ahead, there are two signals to watch. First, $SNDK’s index inclusion is a one-off buying event; after this rally, the key question is whether memory prices follow through. If they do, that would confirm a real cycle. Second, next week’s CPI and the Fed’s stance matter: if strong jobs data hardens rate-hike expectations, this cluster trade will also need to pause.
On the A-share side, the Shanghai Composite was around 3930, down 0.3%, the Shenzhen market fell 0.79%, while Hang Seng moved against the trend and rose 1.74%. There was no extreme market action. Crypto had little excitement: BTC rose 0.65% to stay above 80,000, and ETH rose 2.46% to catch up.
This does not constitute investment advice; it is only a market observation record.
