If someone has the resources they can short sell a penny stock. You say there is no shorting of KATX and that the short volume on the RegSHO reports are only overnight/short term MM shorts. You could only know that for sure if you were a market maker or working for one.
Just like you could only know for a fact that the Rusty Results are poor if you worked for the lab.
I want to thank you Gump for being such an active poster on this board and helping to draw more and more attention to this stock.
