Dow Jones futures rose 0.7 percent by 4:35 a.m. EDT, S&P futures gained 0.9 percent and Nasdaq futures ticked up 0.6 percent, pointing to a higher start for Wall Street's main stock market indexes on Thursday.

The tone was set by Alcoa , whose shares rose 6.8 percent after Wednesday's closing bell on the back of the aluminum group's second-quarter earnings which beat market consensus, sending the stock up 6.5 percent in Frankfurt .

Also after the bell, NetApp rose 5 percent after the data storage equipment maker said it would not match EMC Corp's $2.4 billion offer for Data Domain Inc , while Kennametal Inc fell 4.5 percent after the industrial tool maker said it would offer 6.5 million shares of common stock.

Oil major Chevron is the only S&P 500 company reporting on Thursday.

In U.S. economic data, weekly jobless claims are due at 8:30 a.m. EDT and May wholesale inventories at 10 a.m. EDT.
