Wall Street stocks finished lower Wednesday as a morning rally faded amid nagging questions following two days of chaotic trading and wild price swings.
At the closing bell, the Dow Jones Industrial Average had slipped to 24,892.73, down 0.1 percent, after being in positive territory most of the session.
But the broad-based S&P 500 fell 0.5 percent to end the day at 2,681.56, while the tech-rich Nasdaq Composite Index tumbled 0.9 percent to 7,052.94.
