For the past 80 years, we have created ever more sophisticated models of risk in the economic and investment worlds. With each new tool we create to measure risk, we seem to think we have somehow gained more control over our future. Paradoxically, we appear to believe that the more we understand risk, the more we can somehow control our exposure to it. The more we build elaborate models and see correlations between events and the performance of our investments and the economy, the more confident we become.
And if by some ill fortune we encounter a period of lengthy stability in our models and portfolio performance, we are likely to imbibe a cocktail of collective hubris: we actually think we understand some things in a quantifiable way. We thereupon seek to take on more risk at precisely the time when additional risk is the most disastrous. This week we explore the difference between risk and uncertainty. Perhaps we can even tie all this into our understanding of secular bull and bear markets.
