The Hidden Psychology Behind Market FOMO

Most people have had that moment when they’re walking along outside, enjoying a sunny day, and suddenly something long and twisty on the ground catches their eye. Before they even know what’s happening, their whole body jumps and their brain shouts, “Snake!”

A second later they realize it’s just a garden hose, a stick or maybe even a shoelace someone dropped on the sidewalk. They may laugh, shake their head and keep walking. But for most people, that intense feeling of anxiety and activation lingers for a while.

It’s amazing how fast—and intensely—the brain reacts, even when there’s nothing to fear.

That tiny drama is a perfect example of how powerful heuristics are. Most advisors know the term “heuristics,” the mental shortcuts that help us make quick decisions without thinking too hard. They’re useful some of the time, but sometimes they get too activated and cause us to be jarred emotionally.

When your brain sees something that looks even a little bit like a snake, it doesn’t wait for a careful analysis. It fires an ancient survival response that helped our ancestors stay alive. The reaction is fast, emotional and completely automatic. You don’t choose it—a small, ancient part of the brain chooses the intense reaction for you.

This is the same kind of reaction that investors experience, especially when they feel the fear of missing out (FOMO). The brain sees something that looks like an opportunity, but before its rational part has a chance to weigh the facts, the emotional part leaps forward. It’s the financial version of being startled by a garden hose.

Just like the snake reaction, FOMO feels very real and very intense in the moment. However, observations over the past 30 years of investor behavior have revealed that investment decisions driven by FOMO are not at all based on reality.
