Sept 3 (Reuters) - Wall Street’s main indexes fell on Friday as a sharp slowdown in jobs growth last month gave the strongest signal yet that a post-pandemic economic rebound was losing steam, while banking stocks broadly tracked a jump in bond yields. The Dow Jones Industrial Average fell 42.09 points, or 0.12%, at the open to 35,401.73. The S&P 500 opened lower by 4.53 points, or 0.10%, at 4,532.42, while the Nasdaq Composite dropped 17.76 points, or 0.12%, to 15,313.42 at the opening bell.
