To be fair to the ignorant, there is pretty much zero information on the internet regarding short sellers in the OTC.
No customer service rep at E*Trade / Schwab / TDA / Fidelity is going to know about shady MMs and their OTC shorting practices.
No chance this shorting is retail because no retail with the margin requirement required to short ($2.50 / share) is spending their time shorting penny stocks.
It’s all institutions such as ASCM/CFGN/OTCX (Note: OTCX can be retail as well)
Anyone watching L2 on CAVR and many other tickers can witness daily the shady activity going on via ASCM/CFGN/OTCX. Their presence and actions combined with daily short volume data reported by FINRA paint a complete picture and serves as irrefutable proof of short selling activity in the OTC.
