Easy. Manipulation. Think about it, if you were a hedge fund manager who shorted this at $30 then you would be very smart to short more here, lots, this morning, in short bursts, to make things look bad. This way your short selling could be misinterpreted as something questionable about the results. Then, when all the stop-losses of retail investors start automatically triggering, you can cover your short while preventing a major rally.
The smart HFM will then quietly start covering on dips and keep gently bumping up the short-cover price to reduce short exposure and lock in profits or minimize losses.
