The Dow logged its third-straight day of triple-digit moves. All three major averages suffered their sharpest one-day drops this year on Monday, before recovering most of those losses on Tuesday. With the session's declines, stocks are on pace for their biggest weekly losses of 2013.

"Given the weakened technical picture, the market didn't need a significant catalyst for a sharp selloff," wrote Elliot Spar, market strategist at Stifel NIcolaus. "However, just too many things going wrong in short period of time, brings out sellers and selling begets more selling."

S&P 500

The Dow Jones Industrial Average slumped 138.19 points, or 0.94 percent, to close at 14,618.59, dragged by Bank of America and JPMorgan. The blue-chip index was down 195 points at its session low.

The S&P 500 fell 22.56 points, or 1.43 percent, to end at 1,552.01. And the Nasdaq dropped 59.96 points, or 1.84 percent, to finish at 3,204.67. The CBOE Volatility Index (VIX), widely considered the best gauge of fear in the market, shot above 16.
