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.

Kohl’s stock more than doubled at its intraday peak Tuesday, then pulled back, a day after Opendoor shares did the same.

After this rough patch, Opendoor has emerged as a much smaller company, buying less than 4,000 homes every quarter but one since 2022 compared to 15,000 at the peak in the September quarter of 2021.
