Fish,
You wrote, "Anybody covering Friday was short the day before."
I have no argument with that concept. That short position may have been held for a long time. The holder may have had a pressing need to cover. Or it may not have been short covering at all. In fact, I hope it was not and there is follow on buying tomorrow.
If you believe there was not short selling as the sp here tumbled down from $10.00 to $0.01, you, sir, should not be playing in this game..JMO
