Facebook’s ‘Really Big’ Win: Pachter

Facebook doubled its mobile revenue sequentially, which makes the company's stock attractive, Michael Pachter of Wedbush Securities said Thursday.

"I don't think that the company's future changed much, if at all. If anything, I think we're seeing revenue accelerating faster than we were seeing before. I think we're seeing the shift to mobile occurring faster," he said. "Mobile revenue doubled sequentially, which is really big."

Pachter reiterated his "outperform" rating on the stock, as well as a $35 price target.

The move comes as the stock saw downgrades from BMO, Citigroup and Stifel Nicolaus.

On "Fast Money," Pachter reaffirmed his support of the stock – with one caveat.

"The only thing that's holding me back at all is the company once again said they're going to spend a lot more money than we expected," he said.

"So while I took my revenue estimates a lot — $500 million for 2013 — I took my spending estimates up by about the same amount, so my earnings didn't really go up at all," Pachter added. "That's what my competitors are downgrading on."
