We say we are trying to buy into businesses with excellent economics, run by honest and able people at a decent price. We buy very few securities, so we look at it as "focused" investing.
I was lucky enough to be born in a time and place where society values my talent, and gave me a good education to develop that talent, and set up the laws and the finanical system to let me do what I love doing-and make a lot of money doing it. The least I can do is help pay for all that.

To invest successfully over a lifetime does not require a stratospheric IQ, unusual business insights, or inside information. What's needed is a sound intellectual framework for making decisions and the ability to keep emotions from corroding that framework. You must supply the emotional discipline.
To invest successfully, you need not understand beta, efficient markets, modern portfolio theory, option pricing or emerging markets. You may, in fact, be better off knowing nothing of these.

In our view, though, investment students need only two well-taught courses - How to Value a Business, and How to Think About Market Prices.
