Thank Goodness for Volatile Markets!

In my conversations with advisors, I often hear how much they dread market volatility. The idea of political turmoil, a looming recession or (even worse) an extended bear market quickly becomes the anxiety-driven theme of the discussion. These events are painful, and it is a good thing that they don’t happen very often. But few advisors consider that without the fundamental uncertainty of the markets, they wouldn’t have a job!

The human brain is essentially a prediction machine. It is designed to consume information from experiences in the environment, interpret it and then use it to try to predict the future. This process evolved over millions of years to ensure humans’ survival and prosperity in a hostile ecology.

Evolution not only gave us this obsession with predicting the future; it also supplied us with a huge number of built-in mental shortcuts to help us cope with all that hostility. Behavioral scientists call them heuristics: decision-making patterns that are built in to our brains and operate outside of our awareness. Researchers have discovered and defined more than 180 different heuristics.1

So not only does everyone worry about what’s to come and want to take actions to make their personal future safe and secure, but they also react with predictable intensity to threatening circumstances. These reactions are more irrational and instinctive than they are logical and deliberate, for the sake of speed. Heuristics are shortcuts that enable us to react quickly and efficiently when faced with a threat.

Our instinctive reactions are amazingly efficient. If we accidently touch a burning-hot stove, we jerk our hand away before we feel pain. If we are startled, our brain sends adrenaline into our bloodstream to prepare for action before we even know what the threat is. Our bodies are hardwired to react instantaneously.

Many of these reactions are not physical; they operate inside the decision-making processes in our brain. For example, when we have money to invest, we often prefer companies that are familiar. Known as availability bias, this heuristic is the tendency to simplify a decision by using the most immediately available information.
