Twitter IPO interesting at right price

Shares of Twitter, which filed for an initial public offering, could be interesting at the right price, Alpha One Capital Partners Chief Investment Officer Dan Niles said Thursday.

"At a certain value, it's not that interesting," he said. "I mean, Facebook, I don't think I need to remind people what happened there with that IPO.

"But Twitter's in a different space in the sense that when Facebook went public, they had no mobile revenue. Twitter, the estimation this year that I've seen is they did about $250 million in revenues last year, over $500 million this year, but more than half of it is going to be driven by smartphones and tablets."

On CNBC's "Fast Money," Niles said that Facebook was one of his top holdings because of its mobile business.

"This is another play into the same theme," he said.

Niles said that revenues were his top concern.

"The No. 1 thing that I'm going to look at – and this really covers Facebook, Google, Amazon, eBay,Yahoo, so it's the same thing I look at for all of them – is what amount of money are they able to generate," he said.

"If you look at Google, their cost per click is down year over year for seven quarters in a row. The move to mobile is killing them because they can get about half as much money on mobile just because you have smaller surface area to put those ads, relative to desktop, whereas with Facebook, they're ramping and they're doing innovative ads on the mobile platform. Their cost per ad is actually going up.

"That's the No. 1 thing I'm going to be looking at with Twitter is how those two things interplay because it's great if you have a lot of volume, but if your pricing is collapsing, that's a real issue."
