Irrationality, Exuberance, and Bad Decisions

The world may appear to be a rational, deductive place if you are a scientist. But not if you are an investor attempting to understand how markets work. Financial markets are human creations, and humans are irrational. Economics, a truly dismal social science, is an attempt to look backward and create explanatory algorithms about what happened and why. They may have some success with this. But as predictive models, they are mostly useless. More often, they destroy value versus conveying any understanding about economic and business functions, and therefore, give not only useless but awful and typically value-destroying predictions. Participating in the markets requires a broader, more methodical and disciplined approach. Since irrationality pervades most activity, markets move dramatically with uncertainty, and investors react with dramatic moves based on even more uncertainty and lack a reasonable level of understanding and longer-term perspective about what is going on. The world now is more dynamic, volatile, uncertain, and unpredictable. Irrationality drives most market decisions and rising above the noise to be more thoughtful, think deeply and slowly to understand what’s going on, and identify the handful of factors (typically very few) that make all the difference to investment success is the true challenge we face today. That challenge takes work and thoughtful strategies in our irrational world. That world will remain fundamentally irrational from now on, and thoughtful strategies are the only way to succeed in this irrational environment.
