The US stock market rebounded, and Nvidia rose more than 3% before the earnings announcement.

U.S. stocks rallied on Wednesday, ending their longest losing streak since August, as artificial intelligence bellwether Nvidia strengthened ahead of its post-market earnings announcement. The S & P 500 was up more than 1 percent at press time, following a four-day losing streak that was down about 4 percent at one point from its October high. The Nasdaq 100 was up 1.6 percent. Wall Street's most influential stock, Nvidia, is up more than 3 percent, but is still down more than 7 percent so far this month. Moving forward, traders hope Nvidia's results will ease concerns about AI spending and effectively confirm that the current stock market rally is not just another tech bubble. Tom Essay, founder of Sevens Report Research, said Nvidia's results were "widely regarded as the most important market catalyst of the week, and any disappointing results could add to the recent selling pressure, with significant implications for large technology stocks, the broader stock market and risk assets in general".
