NEW YORK (

TheStreet

) -- U.S. stock futures were signaling a higher open for Wall Street Friday after comments from European Central Bank President Mario Draghi boosted investor sentiment for a second day.

On Thursday, Draghi said the ECB was "ready to do whatever it takes to preserve the euro."

European stocks were slipping after finishing higher Thursday while Asian stocks finished Friday's trading session with gains, getting a boost from

Samsung Electronics'

record quarterly profit.

The U.S. economic calendar on Friday includes second-quarter gross domestic product at 8:30 a.m. EDT and the final University of Michigan read on consumer sentiment for July at 9:55 a.m.

Economists are calling for GDP growth of 1.2% in the second quarter, down from 1.9% in the first quarter.

U.S. stocks on Thursday soared as investors seized on Draghi's promise to pull out all stops to keep the eurozone intact.

The

Dow Jones Industrial Average

closed Thursday up 212 points, or 1.67%, to 12,888.

Facebook reported non-GAAP earnings of $295 million, or 12 cents a share, on revenue of $1.18 billion. Analysts were expecting profit of 12 cents a share in the June-ended period on revenue of $1.15 billion.

Amazon.com

(AMZN) - Get Report

, the online retailer, delivered mixed second-quarter results after the market closed Thursday.

The Seattle-based company reported profit of $7 million, or 1 cent a share, on revenue of $12.83 billion. The latest results included a net loss of $65 million related to the acquisition and integration of Kiva Systems.

Analysts were expecting second-quarter profit of 2 cents a share on revenue of $12.88 billion.

For the third quarter ending in September, Amazon forecast an operating loss of between $50 million and $350 million and revenue ranging from $12.9 billion to $14.3 billion. Wall Street's current consensus estimate is for earnings of 14 cents a share in the current quarter on revenue of $14.09 billion.

Samsung saw profit in the April-June quarter rise by 48% from a year earlier to 5.2 trillion won ($4.5 billion), as demand skyrocketed for its Galaxy smartphones.
