On Thursday, stocks experienced a significant surge, driven by positive earnings from Nvidia, which reignited a tech rally fueled by optimism over artificial intelligence. This bullish sentiment persisted despite indications that the Federal Reserve might be slower to cut interest rates than previously anticipated. Both the S&P 500 and the Nasdaq Composite were having their best days of the year. Nvidia's stock soared by 15% to an all-time high, and it was on track to set a record for the most market capitalization added in a single day.
