Futures are lower

Stock futures are slightly lower on Thursday morning as markets await the first estimate of second-quarter Gross Domestic Product.

Near 8:15 a.m. ET, Dow futures were down 39 points, S&P 500 points were down 4 points, and Nasdaq futures were unchanged.

On Wednesday, stocks spiked to session highs and finished in the green for a second day after the Federal Reserve kept rates unchanged, just as expected.

At 8:30 a.m. ET, economists estimate that the data will show GDP growth of 2.5% on an annualized basis, compared to the 0.2% contraction last quarter.

Data on initial jobless claims is also expected at the bottom of the hour.

Ahead of the releases, gold was down by about $9 an ounce, near $1,084.20. The US index was a tad higher at 97.38, and treasuries were lower, with the benchmark 10-year note at 2.31%.
