Manipulation has been an ongoing concern for ScreenPro investors for months now. Is there anything that can be done about it? The short (pun intended) and probably long answer is no. That is unless a group of investors does as that Reddit group did and goes all in and drives the stock price up (to prove a point more than as a solid investment choice). Actually all they got were the exchanges they were using penalized while big hedge funds got a minor rebuke from those involved with government oversight.
Much of the trading today is, imho, influenced by IROC regulations that were repealed in the early to mid 2000s. European exchanges have much more stringent rules to prevent this. Essentially shorting and day trading has been allowed to evolve like the wild, Wild West. There are few, if any, significant rules left to prevent this.
Having said that good companies with solid revenues, profits and continued investor interest (this, I have learned, is really, really important) can prosper so that retail investors who prefer to hold stocks long can still prosper. We are in the midst of that situation with ScreenPro and as WalkingDead and others have surmised those currently manipulating the sp will surely want a much larger reward one day soon.
Here's hoping!!!
