FOX Business: The Power to Proper 

The blue chips fell mildly in choppy trade after the Fed revealed plans to extend "Operation Twist," but came short of unleashing a more potent form of easing that some had hoped for.

According to preliminary calculations, the Dow Jones Industrial Average slipped 13.1 points, or 0.1%, to 12824, the S&P 500 fell 2.3 points, or 0.17%, to 1356 and the Nasdaq Composite rose 0.69 point, or 0.02%, to 2930.

The Federal Reserve said it is going to continue extending the maturity of its balance sheet after the current program ends this month in a bid to push long-term interest rates down. Specifically, it will buy Treasury securities between six and 30 year maturity and then sell or redeem ones with  a maturity of three years or less. Some analysts had hoped the central bank would unleash another quantitative easing program that would actually add to its balance sheet instead of shifting it.
