June 18 (Reuters) - Wall Street's main indexes opened

subdued on Wednesday, ahead of the Federal Reserve's monetary

policy decision, as the Israel-Iran conflict that entered its

sixth day kept investors on edge.

The Dow Jones Industrial Average rose 20.2 points, or

0.05%, at the open to 42,236.03. The S&P 500 rose 5.2

points, or 0.09%, at the open to 5,987.93​, while the Nasdaq

Composite rose 5.8 points, or 0.03%, to 19,526.917 at

the opening bell.
