Aug 5 (Reuters) - Wall Street's main indexes opened higher

on Wednesday, as hopes of a Middle East peace breakthrough

offset the slide in shares of SpaceX and AMD after the upbeat

forecasts issued by the companies failed to impress investors.

The Dow Jones Industrial Average rose 180.2 points,

or 0.33%, at the open to 54,266.12. The S&P 500 rose 35.1

points, or 0.45%, at the open to 7,771.62​, while the Nasdaq

Composite rose 113.0 points, or 0.43%, to 26,698.018 at

the opening bell.
