What is Confirmation Bias?

Confirmation bias is a cognitive bias that affects our decision-making process. It refers to the tendency to seek, interpret, and remember information that confirms our pre-existing beliefs or opinions while ignoring or dismissing information that contradicts them. In essence, our minds "see what they want to see" rather than objectively evaluating information.

Confirmation bias example

An investor believes a particular stock is undervalued. They prioritize news articles, analyst reports, and online discussions that support this view, while dismissing or downplaying any negative information or warnings about the company’s performance.

This behavior reflects selective information gathering, where the investor actively seeks out content that aligns with their beliefs and overlooks information that contradicts them.

They interpret all information through the lens of their pre-existing views, even when the evidence is unclear or contradictory.

Confirmation Bias in Behavioural Finance

In the field of behavioural finance, confirmation bias is a well-documented phenomenon. It influences how investors perceive and process information related to their investments, often leading to suboptimal choices. Let's explore some ways confirmation bias manifests in behavioural finance:

Selective Information Gathering: Investors tend to seek out information that supports their existing investment decisions. For example, if someone believes a particular mutual fund scheme is a good choice, they may actively look for news or reports that highlight its positive performance while ignoring negative news.

Interpreting Information: When confronted with ambiguous data, investors with confirmation bias tend to interpret it in a way that aligns with their existing beliefs. This can lead to a distorted view of the situation.

Overconfidence: Confirmation bias can amplify overconfidence. If an investor is already confident in their investment choices, they may only consider information that reinforces that confidence, leading to an overestimation of their abilities.

Limited Portfolio Review: Investors influenced by confirmation bias may avoid reviewing their portfolios objectively. They may resist selling underperforming investments because doing so would challenge their initial decision to invest in them.

Confirmation Bias in Mutual Fund Investing

Now, let's examine how confirmation bias can affect mutual fund investing:

Fund Selection: When choosing mutual funds, investors may display confirmation bias by primarily considering information that aligns with their initial preferences. They may focus on positive past performance while disregarding potential red flags or alternative options.

Portfolio Monitoring: Investors may become overly optimistic about their mutual fund investments, even when performance falters. They might ignore signals to review or adjust their portfolios because doing so would contradict their earlier choices.

Ignoring Diversification: Confirmation bias can lead investors to concentrate their portfolios in a specific asset class, market sector, or geographic region. They may resist diversifying because it challenges their existing beliefs about what will perform well.

Mitigating Confirmation Bias in Mutual Fund Investing

Understanding confirmation bias is the first step in mitigating its impact on mutual fund investing. Here are some strategies to help investors make more objective decisions:

Seek Diverse Opinions: Encourage multiple perspectives when evaluating mutual funds. Don't solely rely on sources that confirm your existing beliefs. Seek out contrasting views to make a more informed decision.

Review Your Portfolio Regularly: Commit to periodic portfolio reviews and be open to making changes based on performance and changing market conditions. Don't let the fear of contradicting your past decisions prevent you from acting.

Challenge Your Assumptions: Continually challenge your own beliefs and assumptions about investments. Actively seek out information that contradicts your current views to balance your perspective.

Consider Professional Advice: Consulting with financial advisors or experts in mutual fund investing can provide valuable, unbiased insights. Professionals can offer guidance based on your specific financial goals and risk tolerance.

Document Your Decisions: Maintain a record of your investment decisions, including the rationale behind them. This practice can help you reflect on your choices and identify instances of confirmation bias.

Conclusion

Confirmation bias is a prevalent and powerful cognitive bias that can significantly impact decision-making, especially in the realm of behavioural finance and mutual fund investing. By recognizing its presence and actively working to mitigate its effects, investors can make more rational and objective choices when selecting and managing mutual fund investments. Remember, successful investing involves seeking the truth, even when it challenges your preconceived notions.
