|Title:||How unlucky is 25-Sigma?||Authors:||Dowd, Kevin
|Permanent link:||http://hdl.handle.net/10197/1625||Date:||2008||Abstract:||This article examines the likelihood of high-sigma loss events, paying particular attention to the so-called 25-sigma events which a number of financial institutions have allegedly experienced in the recent financial turmoil. The authors discuss several well-known cases and their media coverage, and then examine the probabilities of such events and the periods of time that would elapse before one would expect to witness them. They find that 25-sigma events are far less likely to occur than recent discussions would suggest--so much so, in fact, that they are literally incredible.||Type of material:||Journal Article||Publisher:||Euromoney Institutional Investor||Journal:||Journal of Portfolio Management||Volume:||34||Issue:||4||Start page:||76||End page:||80||Copyright (published version):||2008, Euromoney Institutional Investor PLC||Subject LCSH:||Distribution (Probability theory)
