Behavioral Finance in Investment Advice: How to use Client Psychology to make better Decisions

A customer calls, his voice strained. The stock market has plummeted and he wants to sell immediately. You know his long-term strategy, you know that selling now would be wrong. But rational arguments bounce off. Why? Because emotions have taken over. Behavioral finance provides the answer and shows you how to master such situations. In this article, you will find out which psychological biases influence investment decisions and how you as a financial advisor can better understand, support and retain your clients in the long term.

The most important facts at a glance

• Behavioral finance explains why even well-informed investors make irrational decisions, emotions beat reason
• Cognitive biases such as loss aversion and herd behavior measurably influence over 90 percent of all investment decisions
• By understanding these biases,financial advisors can provide clients with targeted support and actively avoid costly mistakes
• Systematic investment strategies such as the Everon Portfolio Engine reduce emotional errors through data-based, quantitative decision-making processes
• Practical tools and proven discussion guidelines help advisors to recognize biases in daily practice and address them constructively

What is behavioral finance?

Behavioral finance combines psychology with finance. The discipline examines how human emotions, cognitive biases and social influences shape investment decisions. Unlike traditional financial theories, which assume that market participants act rationally, behavioral finance shows that people often make decisions irrationally.

The foundations were laid by psychologists Daniel Kahneman and Amos Tversky in the 1970s. Their research proved that systematic errors in thinking, known as biases , distort our judgment. Richard Thaler later developed these findings further and made behavioral finance a recognized field of research.

This insight is key for financial advisors. Those who understand why clients act against their own interests can provide better advice. Market bubbles, crashes and irrational price jumps can be explained by behavioral finance. Knowledge of these mechanisms creates trust and strengthens the relationship between advisor and client in the long term.

The 7 most common biases in investment advice

Psychological biases are not uncommon. They affect almost every investor - regardless of experience or knowledge. It is crucial for financial advisors to recognize these patterns and classify them correctly.

1. Loss aversion - the fear of losses

Psychologically, losses hurt about twice as much as gains are pleasing. This loss aversion leads investors to hold on to falling positions in the hope of recovery. Selling would mean admitting the loss in real terms, an emotionally stressful experience. In practice, you often see this: a client holds on to a losing stock for years, even though he has long since sold winning positions.

2. Overconfidence bias - the overestimation of one’s own abilities

Studies show that 64 percent of investors significantly overestimate their own financial knowledge. This overconfidence leads to risky behavior. Clients ignore diversification, trade too frequently or try to time the market. Male investors are particularly prone to this bias. Women tend to invest more cautiously and therefore achieve better returns on average.

3. Herd mentality - the herd behavior

People follow the lead of others, especially in uncertain situations. This herd mentality explains why investors enter overheated markets or sell in panic when everyone is selling.

4. Confirmation bias - the confirmation error

Investors prefer to look for information that supports their existing opinion. Facts to the contrary are ignored. A customer who is convinced of a share only reads positive analyses. Confirmation bias prevents an objective evaluation and leads to one-sided portfolios.

5. Recency bias - the distortion of current events

Current events are overrated, historical data underestimated. After a market slump, many clients expect further losses, although historically speaking, recoveries are the rule. This current event bias leads to short-term, emotional decisions instead of long-term planning.

6. Anchoring - the anchor effect

People fixate on irrelevant reference values. A classic example: a customer wants to buy a share “again at the old price of CHF 100”, even though the fundamental data has changed massively. The original purchase price serves as an anchor that has no rational significance.

7. Status quo bias - inertia

Changes are avoided even if they would make sense. Clients ignore rebalancing recommendations because they would rather do nothing. This inertia can impair performance in the long term and increase risks.

Effects of biases on investment performance

The consequences of emotional decisions are dramatic. A study over 30 years shows that a balanced portfolio achieved an average annual return of 8.8 percent. The average investor, however, only achieved 4.8 percent. The reason? Emotional investing: Market timing, panic selling, excessive trading.

Over three decades, this difference adds up to over CHF 840,000 in lost profit on a starting capital of CHF 100,000. Such mistakes are particularly serious in Switzerland, where long-term wealth accumulation via pillar 3a and the freedom of movement is key.

Typical mistakes include

• Selling during market slumps out of fear
• Entering overheated markets out of greed
• Shifting the portfolio too frequently
• Concentrating on a few positions instead of diversification

Recognizing and breaking through these patterns ensures better results in the long term.

How financial advisors can recognize biases

Identifying biases is an art. It requires active listening and a trained eye for emotional signals. Pay attention to your customers’ language. Phrases such as “I’m afraid that…” or “Everyone is buying now…” are warning signals.

Ask specific questions:

• What is your biggest concern about this investment?
• Have you discussed this decision with anyone?
• What information has influenced your opinion?
• How would you advise a friend in this situation?

A mental checklist helps during the conversation:

• Is the client talking about short-term market movements? → Possible recency bias
• Is he referring to acquaintances or media reports? → Indication of stove mentality
• Does he ignore risks or is overly optimistic? → Overconfidence
• Does he not want to sell despite clear losses? → Loss aversion

The earlier you recognize these patterns, the better you can react.

Communication strategies: How to address customer biases

Addressing biases is tricky. Nobody likes to hear that they are acting irrationally. The trick is to make customers understand without snubbing them.

Empathy before facts

Show understanding for your customer’s feelings. Only when they feel understood will they be prepared to think rationally. For example, say: “I understand that the current market situation is unsettling. Many investors feel the same way.”

Ask instead of lecturing

Use the Socratic method. Lead customers to their own insights by asking questions. Example: “What advice would you give to a friend in this situation?” or “What are your long-term goals with this investment?”

Emphasize the long-term perspective

Shift the focus from daily fluctuations to long-term goals. This is particularly effective in the Swiss context: “Your pillar 3a has an investment horizon of 20 years. Short-term fluctuations are normal and have always been overcome historically.”

Use data and facts

Show historical performance data. Explain that every market slump in the last 50 years has been overcome. Facts provide orientation and reduce fear. However, avoid overwhelming the customer with figures.

Systematics as a solution

Explain how systematic approaches minimize emotional mistakes. Rebalancing strategies or automatic savings plans protect against impulsive decisions. “A systematic approach takes emotions out of the equation and ensures better results in the long term.”

Systematic strategies against emotional errors

The best protection against biases is a clearly defined system. Those who stick to fixed rules are less likely to make emotional mistakes. These strategies have proven their worth:

1. Automatic rebalancing

Portfolios are adjusted according to fixed rules. Winners are sold, losers are bought. This goes against your gut feeling, but is successful in the long term. Automaticrebalancing eliminates market timing attempts and keeps the risk profile stable.

2. Systematic diversification

Quantitative models instead of subjective assessments. The Everon Portfolio Engine , for example, uses a multifactor approach. Factors such as momentum, quality and value are systematically evaluated. Emotions play no role.

3. Dollar-cost averaging (DCA)

Regular deposits regardless of the market level. This method is ideal for pillar 3a. Customers buy fewer units when prices are high and more when they are low. This results in a favorable average price in the long term, without timing stress.

4. Long-term investment horizons

The longer the time horizon, the less important short-term fluctuations are. The Swiss pension system with its three pillars is a perfect example of this. If you have 20 or 30 years, you can take a relaxed approach to volatility.

5. Transparent communication

Customers who understand the strategy remain calmer. The Everon app provides a daily portfolio overview and explains decisions transparently. Understanding reduces fear and builds trust.
