Anniversary edition of the DAX Return Triangle (in German)

This is also impressively demonstrated by the special edition of the DAX Return Triangle on the occasion of the 70th anniversary of the Deutsches Aktieninstitut. Over the past 70 years, a portfolio of DAX stocks has generated an average of around 8.9 percent in price gains and dividends per year. Without withdrawals, such a return doubles the value of a stock portfolio roughly every 8 years.
