Duolingo experienced significant insider trading activity recently, with executives executing thirty-five sales totaling over forty-four million dollars. CEO Luis von Ahn and other key stakeholders offloaded substantial equity positions. These divestments occurred following a positive earnings report, while the stock price currently trades near the lower end of its fifty-two-week range.
