損失回避の概念

Loss aversion refers to the tendency of individuals to prefer avoiding losses over acquiring equivalent gains. 

For example, losing fifty dollars is more dissatisfying than the satisfaction of gaining fifty dollars. 

This occurs because people weigh losses more heavily than gains, and the fear of loss often influences decision-making, especially in financial contexts.

For instance, consider Alex, an investor who purchased one hundred shares of Alpha Corp at ten dollars per share. 

Over time, the stock price dropped to eight dollars per share. 

Alex knows that selling at eight dollars would limit further losses and free up capital to invest in better-performing opportunities that might yield potential gains. 

However, the emotional pain of acknowledging the two-dollar-per-share loss keeps Alex from selling. Instead, Alex holds on, hoping the stock will rebound.

This illustrates how loss aversion can override logical decision-making and prevent individuals from exploring more advantageous options.

Understanding and applying loss aversion helps financial advisors frame choices to emphasize potential gains, enabling individuals to make more informed decisions in investing.
