Facebook Insiders Sold $3.9 Billion of Shares Since Scandal

(Bloomberg) -- Eight Facebook Inc. insiders combined to sell about $3.9 billion worth of stock since the Cambridge Analytica data-mining scandal first surfaced on March 17. The sales were part of pre-determined trading plans.

Chief Executive Officer Mark Zuckerberg accounted for about 90 percent of the total, according to data from InsiderInsights.com, which analyzes such transactions. Most of Zuckerberg’s sales are part of a plan announced last September to sell as much as 18 percent of his Facebook stock. Zuckerberg and wife Priscilla Chan pledged in December 2015 to sell most of their shares over time to invest in philanthropic causes.
