Overconfidence: The Dark Side of Risk Tolerance

Advisor Perspectives welcomes guest contributions. The views presented here do not necessarily represent those of Advisor Perspectives

Of all the variables we routinely measure in our behavioral assessments, our research shows that one most accurately predicts risk-taking – overconfidence. It’s time that advisors systematically identify their overconfident clients and develop skills to overcome the bias it breeds.

Risk is one of the most important considerations for portfolio construction and management. Financial advisors need an accurate view of a client’s risk appetite to draw appropriate financial plans. Risk is generally thought of in relation to risk tolerance, which refers to the degree of risk that an investor is willing to endure in the pursuit of a financial objective. It is often influenced by the individual’s experience and perception of the market. To assess risk tolerance, an advisor typically asks clients to rate themselves on a scale or complete a more comprehensive risk assessment. This score is then considered alongside other factors, such as the client’s capacity to take risk.

The role of financial advisors is changing to reflect a decreased emphasis on pure investment advice, due to automation and the democratization of finance. As a result, advisor-initiated risk profiling can provide value beyond portfolio construction if it is also used to inform marketing, communication and client-relationship management. This requires deeper insights into client mindsets, which more “behavioralized” risk-tolerance instruments can provide.

Behavioralizing risk tolerance requires advisors to:

  1. take into account important behavioral aspects of risk tolerance, such as loss aversion, as well as other psychological factors, such as overconfidence and how individuals deal with uncertainty and regret;
  2. use behaviorally meaningful methodologies that best predict investment decisions, such as questions asking people to make trade-offs, scenarios to gauge their behavioral reaction, or real-life trading behavior; and
  3. take a more holistic approach by ensuring a mutual understanding of risk based on the client’s experience and behaviors, as well as hopes and fears.

One psychological factor that is easily overlooked even in behavioral-risk assessments is overconfidence. People with this bias are overly optimistic, particularly with respect to their own skills and competencies. This may lead them to overestimate the likelihood of positive financial outcomes. Investors with excessive confidence may under-diversify and overtrade.
