AVZ Top 20, page-545

A lot of shares changed hands on that speculation driven pump and dump and it was mostly all retailers as there was no significant change in the top twenty. It was retail driven.

I'd say many retailers cashed out, shares were brought by in large by the day traders who would have correctly trader for a quick pip here and there, and rest of the retailers who brought the pump on FOMO are left holding the can. They'll sell when they can to get their money out, I don't believe they'll be in for the long term.
