Saw this so many times with Under Armour from 2010 to 2012. Great oppurtunities when you get earnings reports and stocks don;t run away.
Why don't they run away? Because the game is rigged and wall street likes free lunches. They get the stock excited the day of the earnings or after, but always pull it back to climb in at a cheaper price to get the news for free.
Seen it at least 10X over the last few years for under armour and Deckers now.
