I don't know if it's quite bottom but I consider it a good investment. I too am puzzled about the pps move in light of all the buying pressure, especially when I look at the trades. Who knows whether the shorting is still going on, or how many previous shorts they need to cover and by how much. That's the big ? but until it's over the MMs are clearly manipulating hard on any downtick to keep it there.
I still think the dam is going to break, especially when the float starts to dry up - but also think at that point just prior we can expect the MMs will drill REALLY HARD to shake the weak to get their shares before this goes KABOOM.
