On the losing side, AppLovin (APP) and SanDisk (SNDK) led the damage, tumbling 12.9% to $441.60 and 12.81% to $1,670.44 respectively. Astera Labs (ALAB) wasn't far behind, falling 11.69% to $364.68, while bitcoin miner Cipher Mining (CIFR) shed 9.25% to close at $20.07. The breadth and severity of those declines pointed to sharp selling pressure across segments ranging from ad-tech and storage to AI infrastructure and crypto.
The gainers told a different story. fuboTV (FUBO) led the advance with a 6.37% jump to $9.77, followed by Duolingo (DUOL) up 5.43% to $131.54 and Asana (ASAN) rising 5.18% to $7.71. Vertex (VERX) added 5.01% to reach $13.00, and Salesforce (CRM) gained 4.73% to $171.04. The divergence between the two groups — heavy selling in hardware-adjacent and high-growth names, buying in software and consumer-facing platforms — reflected a selective market where traders appeared to rotate rather than retreat entirely.
