The market is down. Also, because of the craziness happening in Gamestop, AMC Entertainment Holdings, Nokia, etc. (Look at Nokia. Their average volume is 42 million. Today they did over 1 billion in volume.)
People are selling other stocks to get into them. People are selling other stocks to cover their short positions in the above stocks, imo.
Look at MindMed, Red Light Holland, and Numinus Wellness. They're all down just as much as RVVTF.
