A day after Opendoor Technologies Inc. was swept up in the latest round of meme-stock mania, shares of Kohl’s Corp. skyrocketed amid what a behavioral-finance expert describes as a “mini-bubble.” Shares of the discount department-store chain ended the session up 37.

Despite the enthusiasm, Opendoor has significant financial troubles. The company's top line has plummeted from its height in 2022. The company's current annual run rate is well under a third of its 2022 sales. Opendoor has also never turned a profit and has significant negative cash flow.
