Stock index futures turned positive on Thursday after JPMorgan Chase & Co posted quarterly results showing it beat net earnings and revenue estimates.

S&P 500 futures were 1.60 points higher and were about even with 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 climbed 27 points, and Nasdaq 100 futures added 0.50 points.
