Aug 18 (Reuters) - Wall Street was slightly higher in late morning trading on Thursday, boosted by a jump in Wal-Mart shares and higher oil prices.
Wal-Mart rose as much as 3.1 percent to a more than 14-month high of $75.19 after the retailer's better-than-expected quarterly profit. The stock provided the biggest boost to the S&P 500.
Oil stocks rose as Brent crude went above $50 per barrel for the first time in six weeks after major producers prepared to discuss a possible freeze in output. U.S. crude was trading near $47.
Investors also weighed up minutes of the Federal Reserve's July meeting, released on Wednesday, that showed policymakers were divided over whether to raise interest rates in the near-term.
"Yesterday's minutes didn't hold any major surprises for investors," said Thomas Wilson, Managing Director of Wealth Advisory at Brinker Capital, in Berwyn, Pennsylvania.
"The market has been Fed driven so far, it is going through a phase where it will pivot from the Fed to more emphasis on companies growing their revenues."
While traders have almost completely ruled out a hike in September, they have priced in a 41.7 percent chance for a move in December - down from 45.1 percent on Wednesday, according to CME Group's FedWatch tool.
