Stocks gyrated after Federal Reserve chairman Ben Bernanke spoke on Friday morning. They first gave up their morning gains, then bolted to their highs for the day, before settling in-between.
The Dow Jones industrial average ended the day up 90.13 points at 13,090.84.
A half-hour after trading began, Bernanke declared that the Fed is ready to take more action to help an economy that's "far from satisfactory."
Stocks rebounded once investors parsed his comments. At one point the Dow was up as many as 151 points.
