Oct 8 (Reuters) - Wall Street’s main indexes edged higher at open on Friday, led by gains in energy stocks even after data showed U.S. jobs grew far less than expected in September amid a decline in government payrolls. The Dow Jones Industrial Average rose 2.63 points, or 0.01%, at the open to 34,757.57. The S&P 500 opened higher by 6.75 points, or 0.15%, at 4,406.51, while the Nasdaq Composite gained 40.70 points, or 0.28%, to 14,694.72 at the opening bell.
