US stocks hit record highs Tuesday, led by tech gains, on a light holiday-trading day.

US stocks edged higher on Tuesday, closing at new record levels amid light trading volume due to the holiday-shortened trading day. The S&P 500 and Nasdaq Composite both reached all-time highs, driven by strong performance in tech stocks. Investors remained cautious ahead of the Christmas holiday, with markets seeing reduced activity. The Dow Jones Industrial Average also posted gains, marking its second consecutive record close.
