Nvidia's (NVDA) earnings posted record numbers for the company and bolstered a market-wide rally early in Thursday's session. That rally faded by the afternoon when the stock fell 6% from its intraday high. Marley Kayden attributes the selling action to persistent fears of an A.I. bubble despite Nvidia management pointing to "sold out" Blackwell orders suggesting otherwise. She turns to headlines that "weren't favorable" for Nvidia before its report that caused some bulls to backstep.
