AI-Fueled Rally Ignites Wall Street as Yen Rises Amid Suspected Intervention

Wall Street experienced a strong rally on Thursday, driven by renewed optimism around artificial intelligence (AI) and led by Microsoft's significant surge in shares.

The yen also had one of its best days in years, with analysts suspecting that Japanese authorities intervened to boost the currency.

A key aspect of the market movement was Fed Chairman Kevin Warsh's comments on inflation, which sparked a spike in bond yields. However, investors seemed to shrug off this development, focusing instead on AI-driven growth and Microsoft's performance.
