Why it may matterVerify against the original reporting
Strong quarterly beat and elevated guidance, plus a robust cash position, typically drive multiple expansion and near-term price strength, as evidenced by after-hours gains. Similar historical moves occurred when AI-related demand cycles supported semis during capex upswings; risk remains if AI demand cools or supply tightness eases.
