Analysis-Investors look to AI-darling Nvidia’s earnings as US stocks rally wobbles

Bullish investors are hoping Wednesday's earnings report from chip heavyweight Nvidia can rejuvenate a U.S. stocks rally that has stumbled in recent weeks. Nvidia shares have tripled in 2023, underscoring how a rebound in megacap stocks and excitement over the business potential of artificial intelligence have helped propel the S&P 500 to a 14% gain this year. The chipmaker’s year-to-date increase has led gains among the so-called Magnificent Seven group of megacap stocks, which also include Apple and Microsoft.
