After trading nearly even for much of the session, stocks fell sharply late in the day and the S&P 500 closed below its 200-day moving average for the first time since Nov. 16, 2012. The CBOE Volatility index ended at 24.64, its highest close since June 2012.
Investors reacted to a witch's brew of negative catalysts that included a widening Ebola scare, the potential impact on U.S. earnings from tepid global demand, plunging oil prices and a breakdown of technical support levels.
