Stocks surged Thursday, driven by gains in tech giants like Nvidia, Meta, Amazon, Tesla, and Microsoft. The S&P 500 rose 2.03%, Nasdaq climbed 2.74%, and the Dow gained 1.23%, exceeding 40,000. This rally follows three days of gains, despite conflicting signals on US-China trade talks. While the White House suggests a less confrontational approach and a potential South Korea trade deal, China denies ongoing negotiations. Analyst Ross Mayfield expressed caution, citing China's denial of talks. The market's optimism may stem from hopes of a trade deal, rather than concrete progress.
