Of course the pumps fail in the even moderate short term. What I don't understand is that something so elementary accepted as fact can be considered significant education.
Anyone who shorts into the pump is then taking advantage of the very people buying that it claims to save. That in itself is a major irony imo. They make their money off the same people that the pumpsters do, but, somehow the persons account who is wrecked because they bought the short sell in the pump is not a factor and, the short seller into such is a vindicated saint? I think it's fine for people to do it, more power to them but, regardless, they're still making their money off the same hapless souls, in effect, in bed with the promoters and scam companies, just, in a little different way. Since the money comes from the same source, it's more like a unaffectionate couple with backs to each other, yet, still in the same bed.
I know you realize and accept this, I just find it interesting that's all :-)
