The stock was last quoted at $52.34, up 33 cents, on volume of more than 260,000, according to Nasdaq.com. Wal-Mart hasn't participated in the market's broad rally with the shares down 3.2% over the past year vs. a gain of nearly 17% for the S&P 500. "The strength of our earnings performance for fiscal 2011 and Walmart's strong financial position allow us to again increase our dividend payout to shareholders," said Mike Duke, the company's president and CEO. "We continue to generate ample free cash flow to fund store growth across all our markets, make strategic acquisitions and deliver returns to shareholders through dividends and share repurchase." Wal-Mart said it's raised its dividend every year since declaring its first dividend in March 1974.
