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. That, of course, is not the prevailing view at most business schools, whose finance curriculum tends to be dominated by such subjects. In our view, though, investment students need only two well-taught courses - How to Value a Business, and How to Think About Market Prices.
An investor should ordinarily hold a small piece of an outstanding business with the same tenacity that an owner would exhibit if he owned all of that business.
I make no effort to predict the course of general business or the stock market. Period. However, currently there are practices snowballing in the security markets and business world which, while devoid of short term predictive value, bother me as to possible long term consequences.
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.
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.
The capital gains tax is 15 percent now. So I sit there in my office and I make a lot of money by capital gains, and I pay 15 percent, and I pay no payroll tax on it.
I never buy anything unless I can fill out on a piece of paper my reasons. I may be wrong, but I would know the answer to that ...I'm paying $32 billion today for the Coca Cola Company because... If you can't answer that question, you shouldn't buy it. If you can answer that question, and you do it a few times, you'll make a lot of money.
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.
Long ago, Ben Graham taught me that "Price is what you pay; value is what you get." Whether we're talking about socks or stocks, I like buying quality merchandise when it is marked down.
I never attempt to make money on the stock market. I buy on the assumption that they could close the market the next day and not reopen it for five years.
