Ben was a great believer in buying a diversified group of securities, so that he limited his risk.

I'm a passive investor. There are people who are very aggressive; they try to buy companies.

Each year we buy stocks and they go up, we sell them and then we try to buy something cheaper.

Look at companies selling at new lows.

I agree with Warren to keep it simple and not use higher mathematics in your analysis.

We like to buy stocks which we feel are undervalued and then we have to have the guts to buy more when they go down.

You have to have confidence in what you're doing.
