Stock index futures edged lower on Thursday, pointing to a lower market open, after weekly jobless claims jumped to the highest level since February.

In a separate government report, data showed the economy grew at its fastest rate in four years.

S&P 500 futures were down 3.8 points, below fair value, a mathematical formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract.

Dow Jones industrial average futures fell 27 points, and Nasdaq 100 futures lost 5.75 points.
