PLTR declined 9.2% in the last trading session, 17.4% over the past five days, and 37.2% since February 9, in part because insiders sold shares following the expiration of the lock-in period following the stock’s listing. Insiders were initially allowed to sell just 20% of their shares; the limit on their ability to sell their remaining 80% expired last week. While insider stock sales don’t necessarily suggest a company’s weak prospects, PLTR’s recently released mixed fourth quarter (ended December 31, 2020) results could be a reason for worry for investors.
