More experienced investors know otcshortreport's not showing open short volume, thus why the imaginary squeezes don't happen.... the shorts don't exist. The economics and risk of shorting a trips stinky-pinky just don't add up.
If you check FINRA's bi-monthly short position volume for MJMJ or other OTC, you'll see they are miniscule, if not 0, and not a factor in pps.
