I saw that too. Price was moved by a single share trade of $4.65 (or something like that). I nearly crapped my pants and so did many others because they sold into the panic. I'm guessing some stop losses were hit as well but somebody just gobbled them all up. 10 minutes later and everything back to normal.
Somebody saw a golden opportunity to shake the tree and cleaned up that morning. Unfortunately I wasn't fast or brave enough to dive into the discount.
