10-Investing Axioms Every Investor Should Learn


It’s All In The Risk

Robert Rubin, former Secretary of the Treasury, changed the way I thought about risk when he wrote:

“As I think back over the years, I have been guided by four principles for decision making.  First, the only certainty is that there is no certainty.  Second, every decision, as a consequence, is a matter of weighing probabilities.  Third, despite uncertainty we must decide and we must act.  And lastly, we need to judge decisions not only on the results, but on how they were made.

Most people are in denial about uncertainty.  They assume they’re lucky, and that the unpredictable can be reliably forecast.  This keeps business brisk for palm readers, psychics, and stockbrokers, but it’s a terrible way to deal with uncertainty.  If there are no absolutes, then all decisions become matters of judging the probability of different outcomes, and the costs and benefits of each.  Then, on that basis, you can make a good decision.”

It should be obvious that an honest assessment of uncertainty leads to better decisions, but the benefits of Rubin’s approach goes beyond that. For starters, although it may seem contradictory, embracing uncertainty reduces risk while denial increases it. Another benefit of “acknowledged uncertainty” is it keeps you honest. A healthy respect for uncertainty, and a focus on probability, drives you never to be satisfied with your conclusions. It keeps you moving forward to seek out more information, to question conventional thinking and to continually refine your judgments and understanding that difference between certainty and likelihood can make all the difference.

The reality is that we can’t control outcomes; the most we can do is influence the probability of certain outcomes which is why the day to day management of risks and investing based on probabilities, rather than possibilities, is important not only to capital preservation but to investment success over time.
