The Germans used to do that during the dotcom days. Not sure if the shorted it though afterwards. I remember back then the ASX listed Adelong where the director pumped his story in Germany (which was basically lies) and created a storm over in Germany then sold and made quick millions of dollars. He got sentensed to one years jail last year.
There is a story on it here http://www.theage.com.au/news/business/adelong-director-found-guilty/2005/07/04/1120329382068.html
