However, last week I was talking to a currency trader and he told me that before the crash of the Icelandic Krona last year, they calculated the proabability of ISK crashing and they found it to be a 8 sigma (read highly unlikely! or A Black Swan) event… the fact that it happened proves atleast to me that the methods and theory used to analyze the ISK is not correct. I am writing a paper with Dr.Helgi Tomasson with University of Iceland with the title “Can Power Law help us avoid the highly improbable tail events?” hopefully we will be able to answer the above question.
