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.

The latest so-called meme stocks are the department store Kohl’s, which has surged this week, and the online-based real estate company Opendoor Technologies, which has skyrocketed this month. Both companies have been struggling in their respective sectors.
