The German hyperinflation occurred exactly 100 years ago. No other event has probably had such a lasting impact on German society’s relationship with money as this event. In this article I would like to take a closer look at the impact of such Black Swans on our calculations for financial independence.

A few months ago I discovered a great book from 1993 by Gregor Gielen. In this book the author describes a historical performance index of the German stock market since 1870(!). I have updated this index with current data of the CDAX as well as German inflation data until today and integrated it into the simulator.
