Facebook lost $59 million in the third quarter, but the newly publicly traded social networking site saw its shares soar on Wall Street early Wednesday.
Facebook shares gained $4.35, or 22%, to $23.85 in early trading, after the company reported gains from mobile advertising.
Major U.S. stock indexes, meanwhile, edged higher shortly after the opening bell. The Dow Jones industrial average rose 16 points, or 0.1%, to 13,118.
The broader Standard & Poor's 500 index was up four points, or 0.3%, to 1,417. The Nasdaq was up nine points, or 0.3%, to 3,000.
The ability to pull in revenue from ads on smartphones and tablet computers has been a weakness for Facebook, as a growing number of users access the site from those devices.
