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.
The commission of the investment sins listed above is not limited to 'the little guy.' Huge institutional investors, viewed as a group, have long underperformed the unsophisticated index-fund investor who simply sits tight for decades. A major reason has been fees: Many institutions pay substantial sums to consultants who, in turn, recommend high-fee managers. And that is a fool's game.
In my opinion, the entire field of investment management, involving hundreds of billions of dollars, would be more satisfactorily conducted if everyone had a good yardstick for measurement of ability and sensibly applied it.
Take the probability of loss times the amount of possible loss from the probability of gain times the amount of possible gain. That is what we're trying to do. It's imperfect, but that's what it's all about.
Investors... can't pick stocks that are better than average. Stocks are a good thing to own over time. There's only two things you can do wrong: You can buy the wrong ones, and you can buy or sell them at the wrong time. And the truth is you never need to sell them.
There's always a mismatch. I mean, you know, as the economy evolves, it reallocates resources. Now, the real problem, in my view, is - this has been - the prosperity has been unbelievable for the extremely rich people. If you go to 1982, when Forbes put on their first 400 list, those people had $93 billion. They now they have $2.4 trillion, 25 for one. That is - this has been a prosperity that's been disproportionately rewarding to the people on top.
You could take all the gold that's ever been mined, and it would fill a cube 67 feet in each direction. For what that's worth at current gold prices, you could buy all -- not some -- all of the farmland in the United States. Plus, you could buy 10 Exxon Mobils, plus have $1 trillion of walking-around money. Or you could have a big cube of metal. Which would you take? Which is going to produce more value?
The most common cause of low prices is pessimism - sometimes pervasive, sometimes specific to a company or industry. We want to do business in such an environment, not because we like pessimism but because we like the prices it produces.
We need to throw the resources at this that are necessary. But like I say, we are not spending money. I mean, if we buy these assets intelligently, the United States Treasury will make money. I mean, it's borrowing money. It's just a few percent a year.
