SAN FRANCISCO (MarketWatch) -- Big jumps at LinkedIn Corp. and AOL Inc. led the tech sector to strong gains Friday, as investors at the two growing Internet brands cheered the companies' recent quarterly results.

The Nasdaq Composite (RIXF) rose 0.8% to 3,192 while the Philadelphia Semiconductor Index (SOX) rose 1% and the Morgan Stanley High-Tech Index (MSH) edged up about 0.8%.

LinkedIn (LNKD) shares jumped more than 18% to $147 -- putting the stock to a new high and bringing its gains over the past 12 months to more than 90%. The professional social network blew past Wall Street's targets for the fourth quarter and issued a forecast that was also above analysts' estimates.

Gene Munster of Piper Jaffray lifted his price target on the stock to $176 from $150, writing in a note that the company "is still in the relatively early stages of fully monetizing its professional network asset and that the company has the path to continue to grow in the mid-double digit range for at least the next three years."

AOL (AOL) shares rose nearly 11% to $34.86, after the company reported a 57% jump in net income for the fourth quarter, with revenues above analysts' forecasts.

Apple (AAPL) shares picked up 1% in gains to come to $473.60. The stock got a late-day boost Thursday after the company issued a statement saying that it would evaluate a proposal from hedge-fund giant David Einhorn, who's pushing the company to return more cash to shareholders through use of preferred stock.

The company also maintained -- however -- that it is sticking by its proposed amendment on its proxy statement to eliminate the ability to issue such stock without shareholder approval.

Videogame publisher Activision Blizzard (ATVI) jumped more than 9% following its own better-than-expected results. Analysts from Macquarie Capital and Sterne Agee upgraded the stock to the equivalent of buy ratings.

"With the initial 2013 guidance now official, continued strength in core franchises, a solid pipeline of new IP, and the increased likelihood of a more shareholder-friendly capital structure, the next catalysts for Activision are likely positive, in our view," wrote Ben Schachter of Macquarie in a note to clients.

One notable decliner was Riverbed Technology (RVBD) , down nearly 19% after reporting a sharp drop in profit and disappointing outlook. Daniel Ives of FBR Capital downgraded the stock to a market perform rating following the results.

"While we had some concerns initially around the OPNET acquisition (October 2012), it appears Riverbed has an even tougher road ahead than we previously thought due to integration issues related to the acquisition, coupled with headwinds on its core WAN optimization business," he wrote.

Coinstar (CSTR) , the owner of the Redbox DVD kiosk business, fell nearly 9% after the company reported a decline in earnings and an outlook that was below expectations.
