US stocks rise ahead of Bernanke testimony US stocks have closed higher after a strong earnings report from Home Depot and as the market anticipates Wednesday's testimony in Congress by Federal Reserve Chairman Ben Bernanke. The Dow Jones Industrial Average finished up 52.30 (0.34 per cent) at 15,387.58 on Tuesday. The broad-based S&P 500 added 2.87 (0.17 per cent) at 1,669.16, while the tech-rich Nasdaq Composite Index increased 5.69 (0.16 per cent) to 3,502.12. Bernanke will be watched on Wednesday for signs that the Fed might be ready to alter its quantitative easing (QE) policy, or when and how it might reel in its aggressive bond purchases. FTN Financial's Chris Low expects a status-quo update. "I think he will argue that QE is effective policy, that it is bearing fruits, but I don't think he is going to tip his hands in terms of what will happen next with QE, whether they will make it bigger or smaller," Low said.
