S&P 500, Nasdaq Close Lower On Tech Weakness But Recover After-Hours On Strong Micron Earnings — MU, AVGO, GOOGL In Focus

Markets closed lower on Wednesday with the S&P 500 and Nasdaq dragged by broad tech weakness during the session, only to recover after hours when Micron Technology reported earnings that topped expectations. MU's fiscal results showed revenues of $37.4B, up nearly 49% year-over-year, with gross margins of nearly 40% and diluted EPS of $7.59 — numbers that signal the AI memory upcycle is running hotter than feared bears expected.

The beat matters well beyond Micron itself. AVGO, which has built a dominant position in custom AI silicon and networking with $63.9B in revenue growing nearly 24% YoY at a 67.8% gross margin, benefits from the same AI capex wave that's driving HBM and NAND demand. GOOGL, with $402.8B in revenue growing 15% and a 32.8% net margin, sits both as a hyperscaler customer and a cloud competitor whose TPU investments could be validated by rising AI infrastructure confidence.

The second-order setup is a potential short-squeeze and momentum chase into semis if MU's guidance confirms sustained demand. AVGO in particular has become a consensus AI infrastructure name, and any confirmation that hyperscaler capex isn't softening could accelerate multiple expansion. The bear case centers on whether Micron's beat was already priced in across peers after the run-up in semis year-to-date, and whether GOOGL faces antitrust or competitive headwinds that limit its re-rating.

Key watches: MU's explicit HBM and data center guidance language, any AVGO read-through comments, and whether the after-hours recovery holds into the next regular session open. A fade of the after-hours move would signal the market views Micron as a one-off rather than a cycle confirmation.
