During a more regular week, I would be looking for the Algo and team that has been pushing these low floaters this year to pump it further.
I don't think there is enough market participants for them to do their thing in a slow week.
To be clear I think someone employees them to run a stock up when they have a position.
Run it up so that someone can sell into the volume. They could be doing it now, but with less market participants, it's harder to get enough buyers.
