"The term "Black Swan" is used to describe events which are unpredictable, have a tremendous impact, and are rationalized only after the fact.
In economics, great depressions and stock market panics are viewed as Black Swan events. For instance, at the time of the stock market crash of October 1929, there was no known logical reason why stocks should crash and keep going down and down and down and then lead into the greatest depression to that point in history. It was a Black Swan event because nothing in the past pointed to its possibility.
"Go ask your portfolio manager for his definition of risk, and odds are that he will supply you with a measure that excludes the possibility of the Black Swan— hence one that has no better predictive value for assessing the total risks than astrology…" (1)
