Global artificial intelligence stocks and semiconductor manufacturers staged a powerful rally on Tuesday, propelled by the strong market debut of Meta Platforms Inc.’s new personal agent, Muse.
The surge successfully revived investor confidence in the AI trade following a period of volatility driven by valuation concerns and debates over slower development cycles.
