The key to investing is not assessing how much an industry is going to affect society, or how much it will grow, but rather determining the competitive advantage of any given company and, above all, the durability of that advantage.
We rarely use much debt and, when we do, we attempt to structure it on a long-term fixed rate basis. We will reject interesting opportunities rather than over-leverage our balance sheet. This conservatism has penalized our results but it is the only behavior that leaves us comfortable, considering our fiduciary obligations to policyholders, depositors, lenders and the many equity holders who have committed unusually large portions of their net worth to our care.
What could be more advantageous in an intellectual contest - whether it be chess, bridge, or stock selection - than to have opponents who have been taught that thinking is a waste of energy?
I will do anything that is basically covered by the law to reduce Berkshire's tax rate. For example, on wind energy, we get a tax credit if we build a lot of wind farms. That's the only reason to build them. They don't make sense without the tax credit.
If I were the treasury secretary or head of the Fed, you know, I would try to scare the hell the out of the private sector and say, you better save this because you're going down with the ship.
I don't need 15 houses. Owning real estate doesn't mean much to me. I don't like to think about things like that. I don't need 12 boats, or even the world's largest boat with a crew of 80. I'd have to take care of them, to worry about them. I get a lot more fun out of life without all the bells and whistles.
I've learned mainly by reading myself. So I don't think I have any original ideas. Certainly, I talk about reading Graham. I've read Phil Fisher. So I've gotten a lot of my ideas from reading. You can learn a lot from other people. In fact, I think if you learn basically from other people, you don't have to get too many new ideas on your own. You can just apply the best of what you see.
One of the ironies of the stock market is the emphasis on activity. Brokers, using terms such as 'marketability' and 'liquidity,' sing the praises of companies with high share turnover... but investors should understand that what is good for the croupier is not good for the customer. A hyperactive stock market is the pick pocket of enterprise.
The true investor welcomes volatility ... a wildly fluctuating market means that irrationally low prices will periodically be attached to solid businesses.
