On Wednesday, the U.S. stock market staged a rebound, snapping its longest losing streak since August. Leading the charge in the artificial intelligence sector, Nvidia's shares soared ahead of its earnings report scheduled to be released after the market closes. At the time of reporting, the S&P 500 index had climbed more than 1%, marking a reversal from four straight days of losses. Similarly, the Nasdaq 100 index posted a 1.6% gain. Nvidia's stock price itself surged over 3%, though it is still down more than 7% for the month so far.

Investors are keeping a close eye on Nvidia's earnings, hoping that the report will dispel worries about a potential bubble in AI-related spending and confirm that the ongoing stock market upswing is not merely a tech bubble in disguise. The founder of Sevens Report Research emphasized that Nvidia's earnings announcement stands out as the most pivotal event for the market this week. He cautioned that a lackluster performance could intensify selling pressure, with adverse effects rippling across large-cap tech stocks, the broader market, and riskier assets.
