Tech volatility: 5 trades on big movers

Snag Salesforce.com shares amid rumors it could be swallowed up by a larger competitor, some CNBC "Fast Money" traders said Wednesday.

Shares in the cloud computing company closed more than 11 percent higher on Wednesday on reports that it was seeking help from financial advisors for a potential takeover. The potential for more acquisition reports or an agreement gives Salesforce considerable upside, said trader Brian Kelly.

"You've got to be in CRM if you're going to trade it. If you have one or two people going after CRM you're going to have a floor in the stock," he said.

Trader Steve Grasso agreed, noting the stock was "the true way to play" any software sector restructuring.

Salesforce was not the only big-name technology mover on Wednesday. Traders discussed how to play some of the day's biggest gains and losses.

Baidu

Chinese Internet company Baidu dropped nearly 3 percent in extended trading after a mixed quarterly earnings report. Despite beating Wall Street's earnings expectations, Baidu missed on revenue and issued light guidance for the second quarter.

The limited downward move shows that the company remains in decent shape, said trader Dan Nathan. He said the stock looks appealing if it falls below $210 per share, $3 lower than where it traded Wednesday.

Twitter

Social media company Twitter reeled for the second straight day, closing 9 percent lower in the wake of Tuesday's disappointing earnings report.

Trader Steve Grasso said Twitter is "failing tragically" but bought stake in the company Wednesday. He noted that Twitter's weakness makes it a potential takeover target or ripe for activist investor influence.

GoPro

Trader Brian Kelly said he like the wearable camera maker GoPro's stock even after a 12 percent jump Wednesday. The company reported quarterly earnings and revenue that beat analysts' expectations Tuesday.

He compared GoPro's brand recognition to Heinz ketchup, contending that "you can buy ketchup from anybody, but people want Heinz ketchup."
