Sina’s efforts to generate revenue are at an early stage, ABR notes, but they see long term potential–from third-party apps, advertisers, mobile and online shopping–but also a near-term catalyst: They expect Sina to launch its own ad system later this quarter or in the early part of the second quarter.
ABR says Sina Weibo is worth about $2 billion. That translates into $25 a share for Sina and a $71 price target for the stock.
Sina has gained 2% today to $57.08.
