Shenanigans perpetrated by greedy MMs, and impatient flippers that only care about incremental profits and aren't looking at the long view.
The key indicator to watch here is the volume of all of these trades that are forcing the price down. Someone wants shares cheap, and the people who are actively manipulating the PPS are trying to depress investor sentiment by causing a steady decline over months. There has also been some short selling that factors into all of this.
I can only hope that the manipulators lose enough or don't make enough to suit their greed, and will finally move away.
IMHO, of course.
