Personally I'm interested in a low-volatility high-return portfolio with a 60-year performance record. Got any examples?
From the perspective of 60 years? Sure I do. They're called stocks. Search the net for a condensed graph of stock growth from 1900-2000, or 60 years if you can find it, graphed logrithmically, and i'm sure you'll find the growth to be quite steady and strong.
