What follows is a direct quote from the London Evening Standard of Friday, 21 April 2017:
"Footballers' bus bombed in plot to profit from share price fall" by Ross Lydall
"Police today arrested a man alleged to have bombed the Borussia Dortmund soccer team's bus in apparent attempt to cash in on a resulting collapse in the German club's share price"...
"The 28-year old German-Russian man...'Sergei W'. ... was seized in the town of Turbingen"...
"... a triple blast ... as the bus made its way to the club's stadium"...
"German prosecutors today revealed the suspect had bought a large number of 'put options' ... in an attempt to secure a financial windfall."
[A similar tale is told in the movie Casino Royale.]
And if you want to know what is a put option, then I have a book for you: The Financial Times Guide to Options, By Lenny Jordan.
Sweet dreams.
