‘Time for a pause’ on LinkedIn: Analyst

Shares of LinkedIn might be expensive at these levels, even though the company looks strong, Bob Peck of SunTrust Robinson said Thursday.

"We love the company," he said. "We think they're truly building the professional platform as a service. They have a bunch of new products they're just sort of hitting. They've got their Influencer program, which is creating more of a daily portal. They've got their LinkedIn sponsored updates, which is now finally monetizing mobile. Now they also have Sales Navigator, which is making more of a CRM."

The company, whose shares traded midday around $210 per share, up 3 percent, was expected to release its quarterly earnings report after the stock market close.

On CNBC's "Fast Money," Peck added a caveat to his assessment on LinkedIn stock.

"The big 'but' is valuation. It trades at 40 times EBITDA, 130 times earnings. I get Facebook for 20 times EBITDA," he said. "So, I think a lot of it is priced in right now. I think it's time for a pause."

Peck had a "neutral" rating on LinkedIn stock, with a price target of $215 per share.

Facebook's revenue re-acceleration and incremental margins for the second quarter were two strong arguments in Peck's "buy" rating, he added.

But he wasn't raising his $40 price target on the stock.

"We want to digest and see how their other products have done," he said. "We'll monitor how the progress is on the new products going forward."
