Short-term market forecasts

We have long felt that the only value of stock forecasters is to make fortune-tellers look good. Even now, Charlie (Munger) and I continue to believe that short-term market forecasts are poison and should be kept locked up in a safe place, away from children and also from grown-up who behave in the market like children.

Price action

For some reason, people take their cues from price action rather than from values. What doesn’t work is when you start doing things that you don’t understand or because they worked last week for somebody else. The dumbest reason in the world to buy a stock is because it’s going up.

To invest successfully


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 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.
