For some market wisdom and entertainment on the nature of luck and randomness, this is the home page of the author of The Black Swan

To quote, this site is:
"Dedicated to value creation, ballyhoo deflation and applying the scientific method in finance..."
It is a US site consisting of a series of short articles or snapshots with a broad scope and remit, so many are not relevant. For example one of the recent articles relates to a very expensive electric sports car! The focus is again on the banking sector.
