Another article[1] on WSJ has as its title "Groupon posts surprise loss" and I thought, how is it a surprise? Personally I was expecting a loss, when I read through their S-1 both before and after the amendments the numbers still didn't add up. If I could find a reasonable source of Groupon stock to borrow for 12 months I'd be tempted to short.
