What's Going On With the Fall in Amazon Stock?

Amazon shares are down Monday after a report that the U.S. Federal Trade Commission plans to sue over allegations that the company secretly manipulated ad prices paid by merchants on its platform. The potential antitrust/regulatory action raises meaningful downside risk for AMZN’s advertising business and costs related to legal defense and remedies, likely pressuring the stock 1-3%+. The news is negative but not yet confirmed as formal litigation.
