April 8 (Reuters) - Wall Street's main indexes opened

higher on Monday as most megacap stocks gained, although gains

were kept in check after Treasury yields rose on rising bets

that the U.S. Federal Reserve could delay rate cuts this year.

The Dow Jones Industrial Average rose 12.38 points,

or 0.03%, at the open to 38,916.42.

The S&P 500 opened higher by 7.03 points, or 0.14%,

at 5,211.37, while the Nasdaq Composite gained 36.66

points, or 0.23%, to 16,285.18 at the opening bell.
