 Shares of Opendoor Technologies Inc. OPEN, -2.34 fell 2.7 in afternoon trading Monday, after the U.S. Federal Trade Commission said subsidiary online home buying company Opendoor Labs Inc. will have to pay 62 million for deceiving potential home sellers. The FTC said it took the action because of its allegations that Opendoor pitched potential sellers using misleading and deceptive information, and in reality, most people who sold to Opendoor made thousands of dollars less than if they sold their homes using the traditional process.
