Our job as investment advisors and portfolio managers is to capture returns from global capital markets while controlling portfolio risk. We do this by maximizing diversification, minimizing costs and seeking to make portfolios as tax efficient as possible.
A critical element in this work is matching portfolio risk to our clients’ risk tolerance. Your tolerance for risk depends not only on how comfortable you are with uncertainty, but also your capacity to take risk given your age, financial situation and life goals.
Last spring, Ken French, in association with Dimensional Fund Advisors, published an essay entitled Five Things I Know About Investing. French, a professor at Dartmouth College, is a giant in the world of finance who is best known for his work with Nobel Prize winner Eugene Fama.
The first part of his essay deals with risk. French proposes a definition of risk that steers clear of such technical concepts as volatility, standard deviation and beta. Instead, he defines risk as “uncertainty about lifetime consumption.”
He explains that people invest because they want to use their wealth in the future to achieve important goals like enjoying financial security, supporting the people and causes they care about and retiring comfortably. Risk is uncertainty about how much wealth it will take to achieve those lifetime goals.
“Some might plan to spend all the money on themselves for things like food, shelter, travel, recreation and medical care,” French says. “Others may plan to spend some of their wealth on political contributions, charitable donations, or gifts and bequests to their children…Investors like a high expected return because it increases the expected wealth that will be available to spend or give away. And everything else the same, risk averse investors prefer less uncertainty about their future wealth.”
In this light, the financial author Morgan Housel makes some important observations in his book The Psychology of Money about how risk and unforeseen events can jeopardize your future wealth.
“A plan is only useful if it can survive reality,” Housel writes in this excerpt from his book. “And a future filled with unknowns is everyone’s reality.”
According to Housel, surviving future unknowns to build wealth for lifetime consumption comes down to three things.
We have to accept risk and cope with uncertainty to build wealth and achieve the goals we have set for ourselves. The key is to understand the risks you are taking; ensure they are consistent with your tolerance for risk; and control them prudently and consistently over time.
