SAN FRANCISCO (MarketWatch) -- Tech stocks tried to bounce back from the prior-day's losses Friday, with Twitter Inc. positioning itself among the gainers in the wake of a report that highlighted the company's opportunities in the market for online video advertising.

Twitter (TWTR) shares climbed $2.77, or 4%, to $70.27. The microblogging company was seen as benefitting from a report Thursday from Evercore Partners analyst Ken Sena, in which he cited Twitter's opportunities in the market for U.S. online video advertising. Sena estimated that the market for video ads will rise to $8.1 billion by 2016, and that 17% of Twitter's revenue by that year could come from video advertising.

Among other online and social-media companies Facebook Inc. (FB) rose 9 cents a share at $54.78, LinkedIn Corp. (LNKD) was off by 75 cents at $206.89, Amazon.com Inc. (AMZN) rose $2.13 a share to $400.30 and Yahoo Inc. (YHOO) rose 63 cents to $40.22.

Hewlett-Packard Co. (HPQ) recovered from its Thursday losses to rise 64 cents a share, or 2.3%,to $28.30 a share. Gains also came from IBM Corp. (IBM) and Pandora Media Inc. (P).

The tech-heavy Nasdaq Composite Index (RIXF) slipped by 8.73 points to 4,134.3, while the Philadelphia Semiconductor Index (SOX) was also in the red.
