Aug 3 (Reuters) - Wall Street’s main indexes rose on Tuesday, as an upbeat corporate earnings season and a pickup in global deals activity lifted demand for risky equities, although gains were capped by concerns around a surge in the Delta variant of the coronavirus. The Dow Jones Industrial Average rose 25.9 points, or 0.07%, at the open to 34,864.1. The S&P 500 rose 5.6 points, or 0.13%, at the open to 4,392.74, while the Nasdaq Composite rose 32.9 points, or 0.22%, to 14,713.99 at the opening bell.
