Social media stocks hope for a better 2nd half

Social media plays for the second half

The end of first half of the year is a relief for some social media companies, stockwise.

So far this year, Twitter's stock has gone nowhere. And it's down more than 10 percent in the past 12 months. Today, CEO Dick Costolo officially steps down while Jack Dorsey takes command of the company as the interim chief executive.

Dorsey has his work cut out for him. Wall Street is demanding that he expand the company's user base with increased engagement that advertisers can monetize. "You need to expand the base outside of that core 300 million users beyond the technophiles and news junkies," said SunTrust's Robert Peck,

Peck said new products in Twitter's pipeline could give the stock a lift, but the ongoing CEO search has him on the sidelines for now with a "neutral" rating and $40 price target. (The stock was trading around $36 mid-Wednesday morning.)

Who could be the next permanent CEO?

Peck believes the top candidates include Dorsey, Adam Bain, Twitter's president of global revenue and partnership, and Ross Levinsohn, Yahoo's former interim CEO.

The team at BGC, however, notes reasons for guarded optimism: Despite the stock slide, the company's value proposition remains intact for its users and customers, they argue. They also said that the stock does tend to perform better in the second half of the year.

Not every social media name is under pressure. Case in point: Facebook, which is up some 10 percent in the first half of 2015.

Bulls maintain that it will move higher from here, pointing to strong engagement, the ramp-up of advertising at Instagram and continued product innovation.

But even some Facebook fans, such as Raymond James analyst Aaron Kessler, highlight some issues for investors to consider before carving out a stake in the social network.

"We still think ad prices are going up, but we have seen a big increase in pricing over the last year as a lot of advertisers have come onto the platform and realized the value of Facebook," Kessler says, adding, "We would caution investors not to expect the same growth in pricing going forward."

Those caveats don't appear to concern hedge funds, however. In fact, Facebook is one of the top five tech holdings among hedge funds, according to the latest data available from Goldman Sachs.

Facebook declined to comment for this story. None of the other companies replied immediately to requests for comment.
