Facebook reeled after earnings on Wednesday, but some CNBC "Fast Money" traders would be quick to scoop up the stock.
The social media giant dropped 2 percent in extended trading after it reported first-quarter revenue that missed analysts' expectations. But as the company's monthly active users in March rose 13 percent year-over-year, to 1.44 billion, trader Brian Kelly would buy on the slide.
"If you can't monetize that, then you really shouldn't be in any type of business whatsoever. So, on weakness, you buy Facebook," Kelly said.
Trader Pete Najarian agreed that the stock has upside.
"I think tomorrow morning, as the dust settles, we're going to start to see really what the direction of Facebook is going to be," he said.
But trader Dan Nathan expressed more skepticism. He noted that user growth and ad revenue on mobile platforms may start to reach a saturation point. He said he preferred Google stock to Facebook.
EBay—another Internet name that reported on Wednesday—soared in extended trading. The company beat Wall Street's earnings and revenue expectations, driven by strong growth in its PayPal service.
The stock popped 5 percent in after-hours to roughly $60 per share. Trader Guy Adami believes eBay shares could "make the push to the next level."
The company also said the previously announced split of eBay and PayPal into separate publicly traded companies would take place in the third quarter. Nathan noted that he would look to take a long position in an independent PayPal and short eBay, as its core marketplace segment fell off 4 percent year-over-year.
