U.S. stocks rebounded on Wednesday, breaking the longest losing streak since August, as Nvidia shares rose over 3% ahead of its earnings report. The S&P 500 climbed more than 1% after four consecutive days of losses, while the Nasdaq 100 increased by 1.6%. Nvidia, considered a key indicator for the AI sector, is expected to be a major market catalyst this week. Tom Essaye of Sevens Report Research highlighted that Nvidia's earnings results could significantly impact market sentiment, with disappointing figures potentially exacerbating recent selling pressure on large tech stocks and broader risk assets.
