SentinelOne Craters 14% While Costco and NetApp Pop — Earnings Season Is Eating Its Young

Let's do a quick vibe check on earnings week: $NTAP popped 17% on an AI-driven beat with Barclays slapping a $199 price target on it. $COST printed 9.8% comparable sales growth vs. a 7.8% consensus — and then announced it would literally mail tariff refunds back to members like some kind of retail Robin Hood. Meanwhile, $S (SentinelOne) nosedived 14% on weak guidance and an 8% workforce cut, which analysts are somehow spinning as bullish for margins. Sure.

The Seeking Alpha YouTube channel noted that SentinelOne carries an A+ profitability grade and a quant Buy rating despite the carnage — because Wall Street loves a restructuring story almost as much as it loves ignoring one. Okta joined the party with an 8% surge after AI agent identity products drove 25% of Q1 bookings, which is the kind of number that makes security bulls feel vindicated after years of being told the sector was crowded.

Costco promising to refund tariffs directly to members while posting monster traffic numbers is the most 2026 thing imaginable — and it's working.
