Why Facebook stock keeps climbing

There's a reason shares of Facebook have been heading back up toward their IPO price, Rosecliff Capital's Mike Murphy said Tuesday.

"Look at Google," he said. "I think you're seeing a lot of rotation coming out of Google, and I think that money's finding a home in Facebook. I think it's going to $38, and if it gets through that it's off to the races."

On CNBC's "Fast Money," Murphy said that inflows would send the stock above its initial public offering price.

"My point was when the stock rallied 26 percent overnight, and I think it was over 40 percent in a matter of a week leading up to those numbers, you're never going to go broke taking that profit," he said.

"After seeing that run-up, I thought there was going to have to be some sort of selling. I was wrong. The stock's continued. And this move you're getting today just tells you there's some major money coming into this stock, and it's going to $38."

Joe Terranova of Virtus Investment Partners said that he was looking at what large investors were doing.

"The most important thing with Facebook, going forward, is that you have to look at the institutional ownership," he said, noting that compared to Microsoft, institutional holdings of Facebook stock was "at least 25 basis points below the historical norm.

"So, there's plenty of institutional flow that now they're seeing the fundamental recovery that's going to come in."

Terranova said that speculative traders such as himself were likely looking for a pullback toward $35 or $33 per share to jump back in.

"I just don't think I'm going to get that, and I think I'm probably going to have to chase after it," he added.

"The stock and the options have told us in Facebook what's going to be happening," he said, noting large bets ahead of earnings, up to nearly 1.5 million per day.

"Where were they taking off positions? No," he said. "They were putting on positions and going for more upside."
