S&P 500 stock index futures pared losses and turned nearly flat on Thursday ahead of key producer price and jobless data and after Wal-Mart Stores Inc reported quarterly earnings in line with estimates.

S&P 500 futures fell 0.8 points and were below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones Industrial Average futures shed 43 points, while Nasdaq 100 futures were up 3 points.
