It's not shorts.
the short position is very small on MTRX. As of today only 92000 shares. The reason the price bounces is day traders and automated trading platforms flipping in the 1/2 penny gap. They buy at 34 sell and 34.5 buy at 34 again sell at 34.5 all day. Once that gap is raised at a higher price they move on to another cheap stock. That's how I see it. We burn them only 1 way. Do not let them have your shares. They can flip eachother off all day..lol. Take Care
