"hmmmm reminds of a certain black friday... 28 cents to 8 cents..." I beleive in SPNG case that it was a liquidation with some people shorting the stock while it was going down. The liquidation also known as a "dump". The dump was so fast that it went through all the highest bid's. It kind of goes like this.
