This stock moves on little to no volume as the float is locked tight, so any sort of decent buying causes the price to jump significantly.
There is pending Q3 release and the Q2 financials were quite nice so people are assuming this will bounce again once the financials are released.
Plus people are assuming news will be released soon as more clinics are set to be opened, so add all that up and people are trying to accumulate shares at the bottom before the next leg.
The issue is any sort of large buying will pop the price.
