Sometimes when you make a trade and you have an odd number of shares in your portfolio sometimes theres a few left over when you didnt order all of them in your sell order and people get sick of seeing them. I still have 4k shares left of NECA on the last pump from .0001 to .0002 and still have those worthless shares in my Etrade. Maybe i will call my broker to get rid of them. Probably similar with CUBV shareholders that dump a few bucks worth of stock to the bid, just trying to tidy up their account. They can also call and ask their broker just to clear it out if its not worth the commission to dump the few worthless shares that the commission exceeds the value
