Wall Street ends mixed; traders look to Nvidia report

STORY: U.S. stocks ended mixed on Friday, with the Dow dropping about two-thirds of a percent, the S&P 500 closing essentially flat and the Nasdaq ticking up marginally.An early selloff dragged all three major indexes down more than 1% before they pared some losses. Investors in recent days have worried the Federal Reserve may hold off on a December rate cut and that AI-related stocks have become too pricey. And while some say fears of a tech bubble are overblown, Grace Glockner, investment team member and director of national accounts at Scharf Investments, takes a more guarded view."It's difficult to say if it's a tech bubble. For the investors, I think a lot of people are pointing to the fact that these companies are very profitable and they have strong balance sheets, right? So they use that as an argument of why it's different than the tech bubble that we saw in the late 90s that ultimately burst in early 2000. But for an equity investor, the majority of the value of those shares still relies on expected earnings growth in the future.":: FileAmong the tech stocks that held steady on Friday... Nvidia, which gained more than one and a half percent, as investors prepare for the AI chipmaker's quarterly results on Wednesday, arguably the most critical of third-quarter earnings season.Among other movers, Warner Bros Discovery gained 4% after the entertainment company said it had amended CEO David Zaslav's employment agreement amid a strategic review of its business.And shares of Cidara Therapeutics more than doubled after Merck said it will acquire the company in an almost $9.2 billion deal.
