Dow Gains 500 Points. S&P 500 and Nasdaq Head for Closing Highs.

The three key indexes furthered their gains mid-day Friday, with riskier assets gaining momentum.

The S&P 500 and the tech-heavy Nasdaq Composite both gained 0.7% each. The Dow Jones Industrial Average was up 518 points, or 1.2%. Each of the indexes had marked more modest gains at open.
