The Nasdaq closed above 17,000 for the first time on Tuesday, driven by Nvidia’s 7% surge and gains in semiconductor stocks. The S&P 500 saw slight gains, while the Dow dropped as rising Treasury yields impacted the market. The tech sector led gains, while healthcare and industrials declined. Afternoon trading saw stocks lose ground due to weak debt auctions pushing Treasury yields to multi-week highs, raising concerns about economic impact and the Federal Reserve’s plans.
