Interesting one, got active at 10:32, scanner should have alerted you. Reported earnings but included the paragraph about a possible Department of Justice investigation not in the 8-K but in the 10-K, which people only discovered later? Maybe there was a conference call and something was revealed on it that caused the stock to go into freefall. Anyway, regardless of the news quick witted traders could have shorted this thing for some serious money.
