To be perfectly honest with each other here, we should literally say we have no idea. Anyone who makes a guess is just making stuff up from their minds or stuff they read somewhere but in reality nobody really knows whats going on.

In order to fully know what happened you have to track every single sale during this bear run and find who it belongs to, talk with them and find out what happened, there is literally no technology that is capable of doing that let alone actual human being who would actually spend time doing it. Hence there is really no point of asking why something is happening or happened. It just happened and now we should focus on the future instead, no point dwelling on past and trying to figure out what happened or why it happened.
