US STOCKS-S&P, Dow futures lower after jobless claims

(Updates with reaction to jobless claims)

NEW YORK, July 24 (Reuters) - The S&P 500 and Dow stock futures fell further on Thursday after data showed a larger-than-expected increase in the number of people filing for unemployment benefits in the latest week.

Nasdaq stock futures were higher, gaining some support from Amazon.com Inc (AMZN.O), whose quarterly profit beat Wall Street's forecasts.

S&P 500 futures SPc1 fell 3.40 points and were about even with 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 DJc1 declined 41 points, and Nasdaq 100 NDc1 futures gained 6 points. (Reporting by Ellis Mnyandu, Editing by Kenneth Barry)
