Wall Street set to open higher after Wal-Mart results

Wall Street looked set to open higher on Tuesday as better-than-expected earnings from Wal-Mart and Home Depot allayed some concerns after last week's sharp selloff in retail stocks. Shares of Wal-Mart rose 1.8 percent to $58.90, while Home Depot was up 2.8 percent at $124.18 in premarket trading. The modest rise in inflation could bolster chances of the Federal Reserve raising interest rates next month.
