The Psychology of Investing
Mon Jan 19 2026
We all like to think we're rational when it comes to money, but the truth is, our brains can be our own worst enemy when making investment decisions. In this episode of clarityON, Investment Director Glyn Bolton and Investment Manager David Eve explore the fascinating world of behavioural finance and reveal how psychological biases cost investors dearly - sometimes to the tune of hundreds of thousands of pounds over a lifetime.
What we cover:
The bias blind spot: Why even experienced investment professionals aren't immune to cognitive biases, and how Morningstar's research shows that high bias levels can cost investors 1.5% per year in returns.Loss aversion: Why we feel losses 2.5 times more strongly than gains, and how this leads us to hold onto bad investments while selling winners too early.FOMO and herding behaviour: From the dot-com bubble to Bitcoin and Nvidia, why buying what "everyone else" is investing in usually means you're buying near the top.Overconfidence: The Dunning-Kruger effect in action—why the most overconfident investors rarely recognise they have a problem, and how even professional fund managers fall into this trap.Action bias: Why doing nothing is often the smartest move, and how missing just the 10 best days in the market can cut your returns in half.The real cost: How behavioural mistakes can mean the difference between retiring with £450,000 or £750,000—a £300,000 gap caused by emotions rather than market performance.The value of advice: Why Royal London's research shows advised individuals accumulate 23% more wealth, and how behavioural coaching accounts for half of the value a financial adviser provides.Glyn and David share real-world examples, debunk common investment myths, and provide a practical "red flag checklist" to help you spot when your biases are influencing your decisions.
Whether you're a seasoned investor or just starting out, this episode will help you understand the psychological traps that derail even the smartest people—and how to avoid them.
