The Absolute Return Letter - December 2010: The Dirty Dozen

In the world of finance, risk is essentially the probability of an investment’s actual return being different from the expected return. As most of us are not overly concerned about actual returns being higher than expected, it is fair to say that in practical terms, risk is a measure of the probability of losing some or all of your investment.

Now, risk cannot always be quantified, and there is indeed a term for immeasurable risk. It is called uncertainty. Good investment management is founded on robust risk management or, as we ought to label it, the ability to manage uncertainty well. Many moons ago, a good friend with more grey hair than myself gave me the advice to focus on the management of uncertainty. His philosophy was that if you manage that well, over time, performance will take care of itself.

Now, I must confess that over time I have made my fair share of mistakes. Managing risk/uncertainty is a heck of a lot more difficult in practice than the mathematicians want us to believe. I am only human. I get carried away from time to time like most other investors. Unless you were born with the DNA of Warren Buffett, keeping emotions at bay when making investment decisions is far from easy.
