Traders: Beware LinkedIn, Pandora earnings pop

LinkedIn and Pandora shares popped after quarterly results Thursday, but some"Fast Money" traders warned against jumping into the stocks.

Battered professional social network LinkedIn beat both earnings and revenue expectations, sending its shares about 7 percent higher. Music streaming company Pandora reported a loss, but still topped estimates, and its shares rose 9 percent.

Traders cautioned on LinkedIn because the company had already lowered its guidance for the quarter significantly. Trader Dan Nathan even said he would not consider it a "beat" because expectations were already so low.

The stock's price seems to high, trader Tim Seymour added, because its user engagement is not as high as other social networks.

However, trader Steve Grasso added the stock could potentially rise as much as 20 percent on a technical basis. Short covering could also send it higher, he added.

Turning to Pandora, Nathan called it "a bit of a mess" which faces "a lot of competition." However, Seymour noted he likes the stock because it still has loyal users and could be a potential takeover target.
