A short squeeze may have been part of it but a larger part was retil investors chasing a rainbow. This morning the last buyer bought at the highest price and sellers looked around and found out they were alone. The sellers started sliding down the exponential curve and no amount of buying offered was big enough to stop the slide. Now fear takes over which is more powerful than greed. I bought in to SCO at $51.95. There could now be a long run up for SCO.
