April 22 (Reuters) - Wall Street's main indexes opened higher on Monday after steep losses in the previous session as easing Middle East tensions buoyed risk appetite, while investors looked ahead to an action-packed week with major tech earnings and a key inflation print.

The Dow Jones Industrial Average rose 130.5 points, or 0.34%, at the open to 38,116.89. The S&P 500 rose 20.1 points, or 0.40%, at the open to 4,987.33, while the Nasdaq Composite rose 114.1 points, or 0.75%, to 15,396.13 at the opening bell.
