I hate to be a party pooper, I really do, and I believe that UDHC should and could trade much higher. But I no longer get excited about those short numbers because this is what I learned.
They include flipper shares as a short. Example. Today I buy UDHC. Tomorrow I sell UDHC. My shares didn't settle. Mr. FINRA lists them as "short."
I determined this because there was a stock that I flipped and the FINRA short list showed my trade as short shares. My trade was 75 percent of the volume for the day, so it was easy for me to pick it apart. (It wasn't UDHC).
If you don't believe me, test the theory.
So when you see a stock with large number of short shares on that list, it's really just getting beat up by flippers.
