Wall Street rises for second day, boosted by banks
But the Dow industrials eked out only a small gain as slumping oil prices pushed energy shares like Exxon Mobil Corp lower.
Jamie Dimon's comments to CNBC television, which reversed a broad decline, came after a speech where he said the bank's bond department had just had its two busiest months ever.
It was the first two-day run-up for the S&P in a month.
The Dow Jones industrial average inched up 3.91 points, or 0.06 percent, to end unofficially at 6,930.40. The Standard & Poor's 500 Index added 1.76 points, or 0.24 percent, to 721.36. The Nasdaq Composite Index gained 13.36 points, or 0.98 percent, to 1,371.64.
