The Rule of 72 is useful in determining how fast money will grow. Take the annual return from any investment, expressed as a percentage, and divide it into 72. The result is the number of years it will take to double your money.

Peter LynchWhen stocks are attractive, you buy them. Sure, they can go lower. I've bought stocks at $12 that went to $2, but then they later went to $30. You just don't know when you can find the bottom.
