Dec 19 (Reuters) - Wall Street's main indexes broadly

rose at the open on Thursday, a day after the Federal Reserve's

projections of fewer-than-expected interest rate cuts and higher

inflation next year wrong footed some investors and pummeled

U.S. stocks.

The Dow Jones Industrial Average rose 137.3 points,

or 0.32%, at the open to 42,464.13. The S&P 500 rose 40.6

points, or 0.69% to 5,912.71​, while the Nasdaq Composite

rose 173.0 points, or 0.89%, to 19,565.664.
