SAN FRANCISCO (MarketWatch) -- Zynga Inc. was a standout gainer among tech stocks Friday, but most of the sector had a hard time remaining in positive territory as trading progressed.

An upbeat jobs report couldn't lift the broad market out of the red, as the Dow Jones Industrial Average (DJI) shed 25 points to 17,527 and the tech-heavy Nasdaq Composite Index (RIXF) was off by 22 points at 4,616.

Zynga (ZNGA) came to life Friday, as the social-and-mobile gaming company's stock rose almost 7%, to $2.51 a share. Late Thursday, Zynga reported better-than-expected third-quarter sales, and the company said mobile games made up 55% of its total bookings in the quarter.

Along with Zynga, small gains came from tech leaders such as Amazon.com Inc.(AMZN), Apple Inc. (AAPL) and Yahoo Inc. (YHOO).

Graphics chip maker Nvidia Corp. (NVDA) shed almost 3% to trade at $19.64 despite the company reporting better-than-expected third-quarter earnings late Thursday. Nvidia also reported gross margins of 55.2% and said its fourth-quarter gross margins would likely remain flat.

Losses also came from Twitter Inc. (TWTR), Netflix Inc. (NFLX) and Microsoft Corp. (MSFT).
