Memory chip boom overshadows oil headwinds, tech earnings loom — July 22, 2026
S&P 500 +0.89% · Nasdaq +1.29% · Dow +0.74% · VIX 17.1 — July 22, 2026
The semiconductor rally is real and broad. Micron, SanDisk, and SK hynix all soared double digits—Micron +12.2%, SanDisk +14.3%, SK hynix +13.7%—on conviction that the memory glut is finally clearing. The S&P and Nasdaq climbed 0.89% and 1.29% respectively, with 74 of the top 100 most active stocks finishing higher. Breadth that clean suggests this isn't a narrow melt-up. Retail is betting the memory pullback everyone feared is already priced in, and the Street is taking that seriously.
Not everything moved the same way. Danaher cratered 11% after Q2 earnings, a blunt reminder that industrial strength still tracks earnings reality, not just sentiment. AST SpaceMobile jumped 10.3% on CEO news that three more satellites are deployed and ready, while Redwire gained 9.5% after opening an Indiana facility for space-based drug development. Coinbase tacked on 9.6% with expansion into Canada on the table. These aren't random pops—they're companies with concrete announcements moving the needle.
The wrinkle: oil is still climbing, and that's tempering some of the AI optimism heading into the real test—Google and Tesla earnings today, and the tech slate continues from there. Google, Microsoft (Microsoft speculation is already flying), and the rest of the chip ecosystem will either justify this move or prove the memory rally got ahead of itself. No insider cluster buys to signal what company leadership thinks today, but the breadth says the crowd is confident enough to hold the line through the earnings cycle.
