Woofun AI reports that major U.S. stock indices opened lower on Tuesday, extending a cautious tone among investors. The S&P 500 fell 0.44%, the Nasdaq Composite dropped 0.65%, and the Dow Jones Industrial Average declined 0.41% in early trading.

The broad-based retreat reflects a risk-off mood on Wall Street, with the Nasdaq weighed down by selling pressure in technology and growth stocks. Bond yields edged higher in pre-market trading, while commodity prices showed mixed signals. No single catalyst dominated the session, suggesting a general reassessment of risk exposure as investors digest corporate earnings and Federal Reserve policy uncertainty.
