The S&P 500 and Nasdaq ended the regular session lower, weighed by broad tech selling, before Micron's blowout earnings report sparked a meaningful after-hours recovery. MU reported FY2025 revenue of $37.4B, a 48.9% YoY surge, with gross margins of 39.8% and diluted EPS of $7.59 — numbers that signal the AI-driven memory upcycle is intact and accelerating.

Micron's result immediately drew attention to its closest semiconductor peers. Broadcom (AVGO) sits at a stronger margin profile — 67.8% gross, 36.2% net on $63.9B in revenue growing 23.9% YoY — and is directly exposed to the same hyperscaler AI capex tailwinds powering MU's beat. Alphabet (GOOGL), as one of the largest buyers of both memory and custom silicon, is the demand-side anchor: its 15.1% revenue growth and 32.8% net margin suggest the cloud spending machine is still running.

The second-order setup is a sympathy lift trade: when a bellwether like MU beats decisively on memory volumes tied to AI infrastructure, it validates the capex cycle that benefits AVGO's custom ASIC and networking chip franchises. The question is how much of that good news is already priced into AVGO after its own strong FY run.

The bear tension is real: the regular-session selloff before the MU print suggests markets were already nervous about stretched valuations in tech, and after-hours moves can fade quickly if broader macro conditions — rates, dollar strength — reassert pressure at the open. GOOGL faces its own AI monetization scrutiny independent of the semis read-through.

Key things to watch: MU's open and whether the gap holds, AVGO's reaction as a high-beta AI semis proxy, and any follow-through commentary from hyperscalers on capex commitments that would sustain the memory demand story.
