Understanding how investor psychology influences financial decisions
Successful financial advice is not only about selecting suitable investments or constructing efficient portfolios. A significant part of an adviser’s role is understanding how clients think, react and make decisions — particularly during periods of uncertainty.
Even experienced investors can be influenced by behavioural biases. These unconscious tendencies can affect how clients perceive risk, respond to market movements and make decisions about their long-term financial plans.
For advisers, recognising these biases is essential. By identifying common behavioural patterns, advisers can help clients make more rational decisions, remain focused on their objectives and avoid actions driven by short-term emotions.
Below are five behavioural biases every adviser should understand.
Loss aversion: The fear of losing outweighs the desire to gain
Loss aversion refers to the tendency for people to feel the impact of losses more strongly than they feel the benefit of equivalent gains.
For many investors, the emotional discomfort of losing money can be significantly greater than the satisfaction of achieving a similar return. This can lead to decisions that may not align with long-term investment objectives.
For example, during periods of market volatility, a client may feel an urge to sell investments to avoid further losses. While this reaction is understandable, acting emotionally during market downturns can result in missing potential recoveries and disrupting a carefully planned investment strategy.
Advisers play an important role in helping clients distinguish between short-term market movements and long-term financial outcomes. Providing context, reviewing objectives and reinforcing the original investment strategy can help clients remain focused when emotions are strongest.
Confirmation bias: Seeking information that supports existing beliefs
Confirmation bias occurs when individuals favour information that confirms their existing views while ignoring or dismissing information that challenges them.
In investing, this may appear when a client becomes attached to a particular investment idea, market prediction or economic view. They may focus only on news and opinions that support their perspective while overlooking evidence that suggests a different approach.
For example, an investor who believes a particular sector will outperform may pay close attention to positive reports while disregarding potential risks.
Advisers can help counter confirmation bias by encouraging balanced discussions, presenting different perspectives and focusing decisions on evidence rather than assumptions.
A well-structured financial plan should be guided by objectives and analysis, not simply by beliefs or market opinions.
Anchoring: Becoming influenced by a reference point
Anchoring occurs when people rely too heavily on an initial piece of information when making decisions.
In investment decisions, common examples include focusing on the price at which an investment was originally purchased or comparing current performance only against previous highs.
A client may believe an investment should return to its previous peak before selling, even if the underlying circumstances have changed. Alternatively, they may judge a new investment opportunity based on a historical price rather than its current valuation or future potential.
Advisers can help clients move beyond anchors by encouraging them to consider the broader investment case, current circumstances and long-term objectives rather than relying on a single reference point.
Recency bias: Giving too much importance to recent events
Recency bias occurs when people place greater emphasis on recent experiences or information when making decisions.
Financial markets often create strong examples of this behaviour. After a period of strong market performance, investors may assume positive returns will continue indefinitely. Following a market decline, they may become overly pessimistic and expect further losses.
This short-term focus can lead investors to make decisions based on recent events rather than long-term market trends.
Advisers can help clients maintain perspective by explaining market cycles, reviewing historical patterns and reinforcing the importance of staying committed to an appropriate investment strategy.
Herd mentality: Following the actions of others
Herd mentality describes the tendency to follow the decisions or behaviours of a larger group.
In financial markets, this can contribute to investment bubbles, market rallies driven by enthusiasm or widespread selling during periods of fear.
Clients may feel pressure to invest in popular assets because “everyone else is doing it” or may become concerned when others are moving away from certain investments.
However, successful investing requires decisions based on individual circumstances, not market trends or social influence.
Advisers provide an important source of discipline by helping clients focus on their personal goals, risk tolerance and long-term strategy rather than external noise.
The adviser’s role in managing behavioural biases
Behavioural biases are a natural part of human decision-making. They cannot always be eliminated, but they can be recognised and managed.
The adviser’s role extends beyond investment selection. It includes helping clients understand their own behaviours, providing objective guidance and creating a framework that supports better decision-making over time.
By recognising biases such as loss aversion, confirmation bias, anchoring, recency bias and herd mentality, advisers can help clients avoid emotional reactions and remain focused on their long-term financial goals.
At Cornerstone, we believe that effective financial advice combines investment expertise with a deep understanding of investor behaviour. By helping clients understand not only what they are investing in, but also why they make certain decisions, advisers can build stronger relationships and support better long-term outcomes.
