March 11 (Reuters) - Wall Street's main indexes opened

lower on Monday, as investors braced for key inflation data this

week that could provide more cues on the U.S. Federal Reserve's

monetary policy path following last week's mixed jobs report.

The Dow Jones Industrial Average fell 55.48 points,

or 0.14%, at the open to 38,667.21.

The S&P 500 opened lower by 11.73 points, or 0.23%,

at 5,111.96, while the Nasdaq Composite dropped 32.49

points, or 0.20%, to 16,052.63 at the opening bell.
