Nvidia's gain helped keep the Nasdaq Composite above water today, with the tech-heavy index climbing 0.2% to 20,677 – a new all-time closing high. However, the Dow Jones Industrial Average shed 1% to 44,023 and the S&P 500 fell 0.4% to 6,243 due in part to weakness in financial stocks.

The Dow Jones Industrial Average finished on a high note Wednesday even as President Donald Trump issued further tariff directives. NvidiaNVDA made history on the stock market today by becoming the first company to hit a $4 trillion valuation.
