I have no idea who could be doing it but I know it is happening and it is happening repeatedly and often. I also can't figure out why anyone should complain when I point out that someone is manipulating the stock price.
If you look at mainly daily charts you may see a day with 120,000 share volume and a closing price of .47 and what you don't see is that 99% of those shares sold for .38. I think that is misleading and dishonest.
Why is that a negative post? The only person that should find that post offensive is the person manipulating the price!
