最新报道:Arm Holdings (ARM) shares plummeted over 19% after the chipmaker announced plans to expand into AI and other markets, despite beating Q3 earnings expectations with $824M revenue. The selloff reflects investor concerns over rising R&D costs and uncertain returns from new ventures, as ARM shifts focus from its core smartphone chip licensing business. CEO Rene Haas defended the strategy, stating AI adoption will drive long-term growth, but analysts warn the transition may pressure margins near-term. ARM's stock drop erased roughly $20B in market value, though shares remain up 50% since its September IPO.
