“Rethinking Investing” – The Essence of Charley Ellis’ Legendary Advice

Charley Ellis on Consuelo Mack Wealthtrack:"What interest rate does it take to double? Take  the 7%. Divide that into 72. Round it off if you want 2 to 10 every ten years doubles. 

So in ten  years it doubles. In 20 years it doubles again.  

In 30 years it doubles again. In 40 years it  doubles again. 

And all you have to do is leave it alone and  let it compound. And the best way to compound,  obviously is equities [and ETFs]. Bonds don't have the  returns. So bonds don't compound as fast."
