An investor’s risk attitude is a stable characteristic, like a personality trait, but risk-taking behavior can change based on the investor’s age, recent market events, and life experiences. These factors change investors’ perceptions of the risks. Differences in risk tolerance between men and women or in different circumstances trace back to emotional as much as rational considerations. Financial advisers should consider all of these factors when advising clients and can use four simple steps to incorporate best practices: be aware, educate, nudge, and hand hold.
