I've seen a few doing that kind of left-side-of-the-bell-curve dance; fortunately, I've generally been sensible enough to sell out before the decline kicks in.

I said "generally". Sooner or later my current warm streak (up 200% in four days) will wind up.

I noticed that yesterday and was selling like a mf!

I keep trying to make my own shares completely worthless, but the system keeps increasing the value despite my having split them into oblivion.
