NEW YORK ( TheStreet) -- U.S. stocks rallied off session lows on Tuesday as St. Louis Federal Bank President James Bullard said quantitative easing remains the best monetary policy option right now. Bullard, speaking in Frankfurt, said financial markets have demonstrated that the bank's stimulus efforts have aided the U.S. recovery following the 2008-2009 recession. The S&P 500 gained 0.17% to close at 1,669.16. Bullard, a voting member of the bank's influential Federal Open Market Committee, said the Fed should continue with its bond-purchasing program because it's still the best way to stimulate the sluggish economic growth. "Quantitative easing is closest to standard monetary policy, involves clear action and has been effective," Bullard said. "You're going to hear Ben Bernanke speak tomorrow," said Michael Bapis, managing director at HighTower's The Bapis Group. "I don't think he's going to provide numbers, but when will they begin tapering -- what would prompt them to raise the pace of QE beyond $85 billion?" Markets were bolstered by Home Depot ( HD) which raised its sales outlook for 2013. Elsewhere, shareholders voted down a proposal to force JPMorgan Chase ( JPM)to split the roles of chief executive and chairman, currently held by Jamie Dimon. Some investors have complained that Dimon wields too much authority at the country's largest bank.

"They seem to be less concerned about the 'stall speed' scenario, in which slow growth morphs into negative growth, i.e., a recession," "So they are less fazed about the phasing out of QE." JPMorgan Chase shares popped 1.4% to $53.02 after a proposal to split Jamie Dimon's dual roles as CEO and chairman failed during the company's annual meeting on Tuesday. Press reports had suggested Dimon could quit if the vote had gone against him. Home Depot gained 2.5% to $78.71 after posting first-quarter earnings that beat expectations by 6 cents at 83 cents a share, as revenue also topped forecasts. The company hiked its full-year earnings and sales outlook. "We continue to see benefit from a recovering housing market that drove a stronger-than-expected start to the year for our business," CEO Frank Blake said in a statement. Medtronic ( MDT) jumped 4.9% to $52.35 as the biggest gaining stock in the S&P 500 after the medical device maker produced fiscal-fourth quarter profit that exceeded Wall Street's target by seven cents at $1.10 a share, with revenue beating estimates as well. Sales growth in the endovascular and structural heart units were especially robust during the quarter. Carnival ( CCL) plunged 4.3% to $33.81 as the biggest loser in the S&P after the cruise line operator slashed its full-year earnings guidance to $1.45 to $1.65 a share, below the average analyst estimate of $1.98. The company is trying to lure in customers with cheaper prices as it continues to suffer the effects of high-profile incidents at its cruise ships. The Dow Jones Industrial Average closed up 0.34% to 15,387.58. The Nasdaq was higher by 0.16% to 3,502.12. New York Fed President William Dudley spoke Tuesday, and Fed Chairman Ben Bernanke will give testimony Wednesday before the Joint Economic Committee of Congress. Investors will be listening carefully for clues on whether Bernanke will hint at a retreat from ultra-accommodative policy during his testimony Wednesday. June gold futures dropped $6.50 to settle at $1,377.60 an ounce. July crude oil lost 75 cents to $96.18 a barrel.
