A lot of garbage. Any stock that suffers an immediate drop in price is subject to a ton of worthless ambulance chasing law-firms looking for a dime off of distraught investors. While a few (and I mean very few) have merit most of them are settled out of court with the law firms making $$$$$$$$ off the insurance company; and the investor left in the dust with at most a few cents.
More lawsuits against Activision Blizzard this week.
