Facebook shares on a tear

Shares of Facebook Inc (NASDAQ:FB) have been tearing it up on Wall Street since the company’s positive earnings report earlier this year. Ebersman isn’t the only executive at the social network to sell off shares. Several executive pre-arranged plans were triggered months ago when the company’s shares approached and then passed their opening day price. So far this year, Ebersman has sold a total of almost 2 million shares. Prior to his share sales this week, he had sold about 901,000 shares for about $30 million, according to Thomson Reuters.

It isn’t uncommon for executives to sell shares in their company, especially when it comes to one like Facebook Inc (NASDAQ:FB) where the stock spent almost the first year of its life on the stock exchange significantly lower than where it opened. It also makes sense because many executives are awarded shares which vest over time, so some simply start selling after a new set of shares vest.
