Tapering fears are back. Stocks finished in the red Wednesday amid new talk that the Federal Reserve may soon begin to slow the pace of its controversial asset purchases.

The Dow Jones industrial average and S&P 500 declined for a third day. It appears that statements from Chicago Fed president Charles Evans and Atlanta Fed president Dennis Lockhart on Tuesday about the Fed possibly pulling back on, or tapering, its bond purchases as soon as next month continued to spook investors. The Nasdaq slipped as well.

The prospect of the Fed cutting back on its massive quantitative easing campaign, which has helped push U.S. stocks to record highs, had investors feeling "uneasy," according to Ishaq Siddiqi, a market strategist at ETX Capital in London. And since Evans is both a well-known Fed dove and a member of the central bank's policy committee this year, the comments are particularly unnerving for traders.

Despite this week's sell-off, the Dow and S&P 500 are only down a little over 1% from the all-time highs reached on Friday. And all three indexes are still up between 18% to 21% so far this year.
