"I thought it was one of the most devastating stories I've read," said Cramer, who has recently been critical of Sandberg and whose charitable trust owns shares of Facebook. "This was distinctly ill-advised. How does this person stay there? How does she stay?"
According to the Times report, Sandberg told subordinates in January to carry out research on the financial interests of hedge fund billionaire George Soros, who had criticized the company during a speech at the World Economic Forum in Davos, Switzerland, that same month.
Sandberg was reportedly attempting to gauge whether Soros stood to gain financially from the attacks by shorting Facebook's shares, a practice in which traders can bet against a company by selling shares they don't own and buying them back at a lower price.
