The Dow Jones industrial average fell 21 points to 15,332 shortly after the opening bell Monday, a loss of 0.1 percent.

The Standard & Poor's 500 index was off a point at 1,665, or 0.1 percent.

Investors will be looking to Federal Reserve Chairman Ben Bernanke's testimony to Congress, scheduled for Wednesday. The Federal Reserve's super-easy monetary policy has been a factor driving stock indexes to record highs this year.
