SAN FRANCISCO (MarketWatch) -- The tech sector was clinging to slight gains Friday, getting a boost from rallying shares of Hewlett-Packard, Groupon and Facebook.

H-P (HPQ) rose more than 4%, while Groupon (GRPN) jumped 6%.

Groupon unveiled a revamped website in a bid to transition from being mainly an online daily deals site to an online market place. The company also introduced updated versions of its smartphone apps.

Shares of Facebook (FB) gained 2% as the social network continued to recover from steep loses following its third-quarter report on Wednesday. Facebook blew past Wall Street estimates, but then rattled investors with comments about signs of declining teen usage and its plan not to ramp up newsfeed ads.

The Nasdaq Composite Index (RIXF) was up 0.1% to 3,925. The benchmark was still down a fraction for the week. The Morgan Stanley High Tech 35 Index (MSH) and the Philadelphia Semiconductor Index(SOX) were each up a fraction.

On the downside, shares of Texas Instruments (TXN) and Advanced Micro Devices (AMD) were in the red. Shares of LinkedIn (LNKD) , Cisco Systems (CSCO) and EMC (EMC) were each also down fractionally.
