The Dow Jones Industrial Average lost 12.94 points Wednesday to close at 12.824.39 after the Fed said it would extend “Operation Twist,” but offered little else to assuage the concerns of anxious investors.

The Nasdaq inched up 0.69 points to end at 2,930.45 while the S&P 500 dipped 2.29 points to finish at 1,355.69.

The Fed's Open Market Committee said it would extend “Operation Twist,” a balance sheet-neutral operation in which the central bank sells short-dated notes and buys longer-term debt, for another $267 billion.

Some analysts and investors view the extension as another sign that the Fed might eventually initiate a third round of quantitative easing, but investors clearly weren’t as optimistic.
