Tech stocks surge as Micron earnings ease AI fears, oil falls further

Micron Technology reported fiscal 2025 results with revenue of $37.4B, up nearly 49% year-over-year, alongside diluted EPS of $7.59 and gross margins of 39.8%. The print landed well enough to broadly lift tech sentiment, with investors reading the numbers as confirmation that hyperscaler AI spending is still translating into real memory demand rather than slowing.

The results matter because Micron is widely viewed as a real-time demand proxy for the entire AI infrastructure cycle — HBM and DRAM volumes tied to GPU clusters make MU one of the most direct reads on whether AI capex is genuinely absorbing supply. A near-50% revenue jump with improving net margins (22.8%) is not a soft beat.

The bull tension here is whether this is cycle peak or cycle mid-point. At these margin levels, bears will argue that DRAM pricing is mean-reverting and that the memory industry's historical boom-bust pattern makes 39.8% gross margins unsustainable into FY2026. The counter is that HBM supply remains structurally tight and that MU is still ramping its HBM3E capacity, which commands pricing well above commodity DRAM.

What to watch: forward guidance language on HBM pricing, any commentary on customer inventory levels at major cloud hyperscalers, and whether the broad tech lift holds into the next session or fades as a one-day sentiment bounce.
