Facebook COO Sandberg sells $26.2 million in stock

Facebook's COO Sheryl Sandberg has sold shares valued at more than $26.2 million, according to a regulatory filing.

Facebook disclosed in an SEC filing that Sandberg sold more than 946,588 shares at prices ranging from $27.39 to 27.90, a level that Facebook hasn't traded at since August.

In fact, Facebook shares have been on a tear in recent weeks, as Wall Street has embraced the company's we're-all-about-mobile message and the biggest so-called lockups on insiders selling their pre-IPO shares have passed, CNET reports.

According to the report, the stock, which rose 1.9%  today to close at $27.49, has soared about 40 percent since early November

This is not Sandberg's only stock sale, but it is her biggest to date.

Most recently, she sold about $4.2 million worth of shares, the report said

And shortly before that, she cashed in $7.4 million worth, it added.
