The strategy we've adopted precludes our following standard diversification dogma. Many pundits would therefore say the strategy must be riskier than that employed by more conventional investors. We disagree. We believe that a policy of portfolio concentration may well decrease risk if it raises, as it should, both the intensity with which an investor thinks about a business and the comfort-level he must feel with its economic characteristics before buying into it.
I dread success. To have succeeded is to have finished one's business on earth, like the male spider who is killed by the female the moment he has succeeded in his courtship. I like the state of continual becoming, with a goal in front and not behind.
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.
When we do not know a person - and also when we do - we have to judge his size by the size and nature of his achievements, as compared with the achievements of others in his special line of business - there is no other way.
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.
At the risk of repetition let me say again that my plea is not for immunity to, but for the most unsparing exposure of, the politician who betrays his trust, of the big business man who makes or spends his fortune in illegitimate or corrupt ways. There should be a resolute effort to hunt every such man out of the position he has disgraced. Expose the crime, and hunt down the criminal; but remember that even in the case of crime, if it is attacked in sensational, lurid, and untruthful fashion, the attack may do more damage to the public mind than the crime itself.
