Taper talk: Chatter about Federal Reserve tapering caused some jitters again Tuesday. Atlanta Fed president Dennis Lockhart and Chicago Fed president Charles Evans both hinted that the Fed could begin easing its bond buying program as early as next month.

While speaking to reporters, Evans said he wouldn't rule out the possibility of dialing back the bond program next month, but reiterated that the Fed's decision is going to depend on economic data and the pace of the recovery.

Evans is a voting member on the Fed's monetary policy committee, while Lockhart is not. But the market has paid attention to comments from all Fed members recently for clues about the central bank's next move.

The Fed's stimulus policies, including its bond purchase program, known as quantitative easing, have been widely credited as a major factor in driving stocks higher over the past few years.
