Major U.S. stock indexes notched fresh record highs on Tuesday, powered by Nvidia’s $5 trillion valuation milestone and strong pre-earnings momentum across the tech sector. Investors rotated into growth equities ahead of the Federal Reserve’s upcoming interest-rate announcement. The S&P 500 and Nasdaq both gained over one percent intraday. Market participants said optimism around AI spending, coupled with stable inflation data, supported risk sentiment. Analysts remain watchful for Fed commentary that could shape equity direction into November’s final trading sessions.
