Now that Facebook stock has finally returned to its IPO price of $38, company COO Sheryl Sandberg sold 2.4 million of her shares for a grand total of $91 million last week as part of a pre-arranged trading plan, according to regulatory filings. (The Lean In author has cashed out portions of her stake in the world's popular social media platform platform before, including a $50 million sale after the company went public last May.) This most recent transaction involved just 5 percent of her total holdings in Facebook, which are currently valued at well over $1 billion.
