Tech stocks rally as semiconductor sector recovers

US stock futures showed a rebound on October 19, 2026, following a challenging week for the tech-heavy Nasdaq 100 Index, which experienced its worst performance since April 2025 amid tariff-related market volatility. The recovery was driven by a rise in semiconductor stocks and CoreWeave Inc., a troubled artificial-intelligence company, as the market prepares for the opening bell. CoreWeave's stock surged, signaling renewed investor confidence in the AI sector despite ongoing challenges. The Nasdaq 100's recent decline was attributed to broader market concerns over global trade tensions and supply chain disruptions. Analysts noted that the rebound reflects improved sentiment toward technology stocks, particularly those involved in semiconductor manufacturing and AI development. CoreWeave's performance was highlighted as a bellwether for the broader AI industry, with investors closely watching its trajectory for signs of sector stability. The market's response to these developments suggests a shift in investor focus toward recovery and growth potential in key tech sectors.
