Facebook’s stock value went down to its record low since its IPO, to $17.73 per share on Tuesday, after trading hours. Doug Anmuth, analyst from J.P. Morgan, said, “The Street has been heavily focused on the large lock-up expirations coming in October and November, and we believe the combination of taking Mark Zuckerberg’s shares out of that equation and also shrinking the outstanding share count by 101 million shares (~3.7%) shows management’s confidence in Facebook’s long-term story.”

On the other hand, analysts from Morgan Stanley reported that Facebook’s efforts in improving its mobile functionalities and apps started to pay off. The social networking giant’s mobile monetization is getting better. According to the report, the company’s users are slowly but progressively embracing the idea of mobile Facebook.

Analysts from Bank of America Merrill Lynch maintained a constructive outlook on Facebook’s capability in speeding up its revenue growth from new ad formats. They believe Facebook’s growth is affected by revenue pressure from increasing mobile usage, higher-than-expected social gaming slowdown, higher spending, and lock-up expirations. The research firm maintained a neutral rating and $23 per share price target for Facebook Inc (NASDAQ:FB) stock.
