NEW YORK — U.S. stock futures are up the morning after stocks hit all-time highs in the wake of the Federal Reserve chairman's reassurance about continued support for the economy.

Dow Jones Industrial futures are up 12 points at 15,405. The broader Standard & Poor's 500 futures are up 0.6 points to 1,670.7. Nasdaq futures are up 3 points at 3,058.

On Thursday, the Dow rose 169 points to an all-time closing high of 15,460.92.

Earnings from big banks JPMorgan Chase & Co. and Wells Fargo & Co. gave futures a small boost after coming in better than expected.

Federal Reserve Chairman Ben Bernanke's vow to support the U.S. economy for as long as needed continued to shore up sentiment in global markets Friday despite growing concerns over the scale of the slowdown in China.

In Europe, the FTSE 100 index of leading 100 shares was up 0.4 percent at 6,567 while Germany's rose 0.9 percent to 8,233. The CAC-40 in France was 0.2 percent to 3,876. Asian markets mostly closed slightly higher.
