Stocks making the biggest moves after hours: Snowflake, Marvell Technology, Agilent Technologies & more
Snowflake crushed Q1 estimates and raised full-year guidance on AI demand, while Marvell posted strong AI-driven results after a -4.6% down-day setup, and Agilent topped Q2 estimates. The post-earnings reactions create a bifurcated setup: SNOW and MRVL offer earnings-beat momentum plays, but heavy insider selling at SNOW and a consensus already loaded with Buy ratings temper the conviction.
What happened
Snowflake crushed Q1 estimates and raised full-year guidance on AI demand, while Marvell posted strong AI-driven results after a -4.6% down-day setup, and Agilent topped Q2 estimates.
The read · May 27
Long MRVL into AI earnings momentum — beat on a -4.6% down day with strong consensus and no insider selling pressure makes it the cleaner risk/reward vs SNOW where 23 insider sales in 30 days cap upside.
Wrong if
If guidance commentary is softer than the headline beat or AI capex sentiment reverses on macro news, the gap fills quickly; MRVL trades at a high multiple so any forward estimate cut would punish the stock disproportionately.

The read, in fullWhy it matters
MRVL entered earnings down -4.6% on the day, creating a depressed base for a beat-driven gap. Consensus is overwhelmingly bullish (13 Strong Buy / 29 Buy / 8 Hold, zero sells) with no insider selling in the last 30 days — a cleaner setup than SNOW where 23 insider sales in 30 days signal distribution near current levels despite the earnings beat. The AI infrastructure theme driving custom ASIC and networking demand gives MRVL a durable fundamental tailwind that should sustain near-term multiple expansion.
