The central bank will release minutes from its July meeting Wednesday afternoon. While the Fed didn't announce any further stimulus measures at its latest meeting, investors will look for clues about whether quantitative easing could be coming when chairman Ben Bernanke speaks at the Jackson Hole, Wyo., symposium at the end of the month.
