The purpose of any investment is to make a profit and create wealth. While the financial goals may vary – from funding a foreign vacation to building a nest egg – the main motive is to get more returns than those possible with traditional banking products. While some investors may be more willing than others in terms of taking a higher level of risk, one thing is certain – nobody wants to lose money.
However, many investors often react in an irrational, reckless or hasty manner to market changes. But why do investors make such knee-jerk decisions? This discipline gives us the answers.
What is behavioural finance?
Behavioural finance is a discipline that focuses on finding out how human psychology affects the decision-making process of investors and the financial markets. It explains why investors make decisions based on their biases, emotions, and personal experiences instead of rational decisions backed by data and research.
Core concepts of behavioural finance
This area of study challenges the notion that investors are rational and markets are efficient by highlighting how emotional and cognitive biases influence investment behaviour. Here are some core elements of investor behavioural.
Key fundamentals of this area of study include:
- Heuristics: Investors use mental shortcuts or rules of thumb to make decisions, often leading to systematic errors or biases.
- Overconfidence: Investors often overestimate their knowledge and abilities, leading to excessive risk-taking and poor decision-making.
- Anchoring: People tend to rely too heavily on the first piece of information they receive (the “anchor”) when making decision.
- Prospect theory: This suggests that people value gains and losses differently, leading to risk-averse behaviour with gains and risk-seeking behaviour when it comes to losses.

Common investor biases
Some of the common cognitive biases in this discipline are:
- Overconfidence bias: Just as a runner might overestimate their abilities and push too hard at the start of a marathon, investors with overconfidence bias tend to believe they can beat the market consistently. This can lead to excessive trading and poor long-term results.
- Self-attribution bias: When investors believe that a good outcome from their investment comes because of their skilfull analysis and any bad outcome is a result of bad luck, it is known as self-attribution bias.
- Loss aversion: Many investors lose out on sound investment opportunities when their focus is on trying to avoid a loss. This is known as loss aversion. It is important to note that even the most non-conservative investor can behave this way during their investment journey.
- Confirmation bias: When investors believe any information, result or news related to an investment belief they have as confirmation while ignoring any contradictory information, it is known as confirmation bias.
- Herd mentality: If investors start following a trend instead of doing proper research, believing that others may have already done the research – it is known as herd mentality. In such cases, a small event has the potential to disrupt the market and economy.
- Disposition bias: Some investors sell well-performing stocks and hold on to ill-performing stocks for a long time believing that the tide will turn. The stock prices continue to fall but they keep holding on to them, thinking that the price will soon increase, and they will make profits. This is known as disposition bias.
- Representativeness bias: Sometimes investors believe that two independently existing things are correlated if they encounter them together on more than one occasion. This linking of two things or events leads to representative bias.
One or more of these cognitive biases may come into play when an investor makes financial decisions.
Importance of behavioural finance
Now that you know the behavioural finance meaning, you may be wondering why you need to understand it. The answer is simple-it can help you make better investment decisions.
Stock markets have been around since the 1600s. People have been investing in stocks for a long time. The process of finding suitable stocks, buying at the right time, and selling at an appropriate time has been refined through the centuries. Presently, there are more tools to analyse stocks and the stock market than ever. And thanks to technological advancements, data is now available at the click of a button and investors can analyse it in minutes if not seconds.
And yet, there is no dearth of investors making irrational decisions.
Clearly, something else is at play here – cognitive bias and limits to arbitrage. These are the two pillars of this discipline. Both offer answers to how emotions and biases affect share prices and financial markets. While cognitive bias influences how people behave, limits to arbitrage explain how effective or ineffective arbitrage forces are in different circumstances.
How does behavioural finance differ from traditional finance?
Traditional finance assumes that investors make rational decisions based on available information and that market prices reflect a stock’s true value. Behavioural finance takes a more realistic view, recognising that emotions, biases and psychological factors often influence investment choices. While traditional finance focuses on fundamentals, behavioural finance explains how fear, greed, overconfidence and herd behaviour can sometimes cause investors—and markets—to act irrationally.
Investment types in behavioral finance
Now that we understand some behavioral finance concepts, let’s explore how they influence different investment types:
- Stocks: Behavioral biases can lead investors to buy high during market frenzies and sell low when panic sets in. Long-term investors should focus on a well-diversified portfolio and avoid emotional reactions to market fluctuations.
- Bonds: Investors may underestimate the risk associated with certain bonds, assuming they are safe. A behavioral finance approach encourages diversification within the fixed-income portion of a portfolio, helping investors manage risk over the long term.
- Real estate: Behavioral biases can affect real estate investments, leading to speculation and overvaluation in certain markets. Long-term real estate investors should research and analyze property values and market trends rather than succumbing to the hype.
- Mutual Funds and ETFs: These investment vehicles are often favored by long-term investors due to their diversification benefits. However, behavioral biases can still come into play when selecting funds. Investors should consider their long-term goals and risk tolerance rather than chasing short-term performance.
Behavioural finance in the stock market:An Example
During the COVID-19 pandemic, global stock markets witnessed extreme volatility. In the initial months of 2020, fear and uncertainty led many investors to sell investments in panic. This was largely driven by loss aversion.
As markets began recovering later that year, herd mentality entered the picture. Investors rushed to buy stocks in a handful of well-performing sectors simply because others were doing the same. Social media discussions, news coverage and stories of quick profits fuelled this herd mentality.
In many cases, investors purchased stocks at elevated valuations without fully assessing the companies’ fundamentals, growth prospects or risks. When market sentiment changed and valuations corrected, several of these stocks experienced significant declines, leaving late entrants with losses.
This example highlights how emotions such as fear and greed can influence investment decisions. Investors who sold quality investments during the market crash or chased popular stocks during the recovery often made decisions based on sentiment rather than analysis.
Past performance may or may not be sustained in future.
Behavioural biases in mutual fund investment decisions
Mutual funds are a popular investment avenue for many reasons. However, while mutual funds offer the promise of diversification and professional management, the investors’ decisions to buy, hold, or sell the funds are often swayed by psychological biases.
Let’s take a closer look at how some the common behavioural biases may impact investment decisions:
• Loss aversion: This bias refers to the human tendency to fear losses more than enjoy gains. Due to this, investors might hold onto underperforming mutual fund schemes longer than necessary, hoping to break even. In the wait for this fund to rebound, may miss out on other potentially lucrative investment opportunities.
• Mental accounting: Investors often treat money differently based on its source or intended use – an error known as mental accounting. Mental accounting can be particularly tricky with mutual funds. For instance, gains from a mutual fund might be viewed as “free money” and spent unwisely, whereas the principal investment is treated with more caution. This kind of mental separation can lead to inconsistent investment decisions where certain portions of the investment are not optimised for the ideal return potential.
• Recency bias: Mutual fund investors often fall for recency bias, where recent events or trends unduly influence decisions. If a particular sector or type of fund has performed well recently, they might assume it will continue to do so and invest more heavily in it. Conversely, if a fund has underperformed in the recent past, they might avoid it, even if its long-term prospects are solid.
• Confirmation bias: Once an investor has chosen a mutual fund, there is a tendency to seek out information that validates that choice and ignore data that contradicts it. This can lead to an overconfidence in the fund’s potential and a reluctance to reconsider the investment, even when signs suggest it might be time to re-evaluate.
• Herd mentality: This bias manifests when investors follow what everyone else is doing, rather than basing decisions on independent research or their risk profile. If there’s a buzz around a particular mutual fund and many are investing in it, others might jump on the bandwagon, fearing that they are missing out. Conversely, if many are selling a particular fund, it might trigger a panic sell-off, even if the fund’s fundamentals remain strong.
By understanding these behavioural biases and their nuances, mutual fund investors can be more vigilant and make decisions that align with their investment goals and risk tolerance. Awareness, education, and sometimes even a contrarian mindset, are crucial to understand the world of mutual fund investing.
Managing behavioural biases
Awareness is the first step towards overcoming biases. Recognising the behavioural biases of individuals allows one to guard against them or sometimes even employ them advantageously. Here are some ways to effectively manage behavioural biases:
• Recognise, reflect and correct: One of the first steps to combat behavioural biases is self-awareness. By identifying which biases are most likely to impact them, investors can begin to notice patterns in their decision-making and take corrective actions. Knowing one’s behavioural biases can also work to an investor’s advantage. For instance, if an investor recognises their tendency towards loss aversion, they can set stricter rules about when to sell a mutual fund, ensuring they stick to a rational decision-making process.
• Diversify investments: Diversification can act as a safeguard against the fallout from some behavioural biases. If loss aversion makes an investor reluctant to sell a declining mutual fund scheme, a diversified portfolio can help mitigate the impact of potential losses.
• Consult with professionals: Financial advisors and mutual fund managers are not immune to behavioural biases, but their professional training often equips them to manage these biases more effectively. Engaging with professionals can provide an objective perspective, helping to counteract personal biases.
Understand your investment: It involves analyzing the fundamentals of the assets you’re investing in, such as stocks, bonds, or mutual funds. This understanding can help you make informed choices.
Do a risk assessment: Investors who emphasize the thinking process take the time to assess the risks associated with their investments. They consider factors like market conditions, economic trends, and the potential for gains or losses. This approach helps in managing financial risk in behavioral investment.
Long-term perspective: A focus on the thinking process often involves a long-term perspective. Instead of trying to make quick gains, investors take a patient approach. They understand that market fluctuations are part of the journey and that a long-term view can help mitigate short-term losses.
Emotion control: Emotions like fear and greed can cloud judgment. A thinking process-centered approach encourages emotional control. Investors are less likely to panic when markets are down or become overly exuberant during a bull market
Impact of behavioral finance on portfolio rebalancing
Emotions and cognitive biases often make it challenging for investors to stick to their planned asset mix. Fear or overconfidence drives us to make quick changes. Here’s a list of such behavioral influences:
- Anchoring and disposition effect can lead investors to hold on to underperforming mutual funds for too long due to loss aversion or because of the initial promise they held. As a result, allocations can drift from targets and rebalancing is delayed unnecessarily.
- Herding behavior can result in panic selling or panic buying, which in turn can lead to market crashes or economic bubbles.
- Recency bias can lead investors to make decisions based on short-term trends rather than more reliable long-term performance. Loss aversion and momentum together ensure investors are slow to sell loss-making mutual funds but quick to exit current gainers.
Ultimately, cognitive biases can hamper the investor’s choice of fund as well as decisions related to reviewing and rebalancing their portfolio. Instead of taking timely rebalancing and reallocation decisions based on performance alone, several biases come into play.
Conclusion
In conclusion, this discipline explains how human psychology works and affects the world of finance. It tells us that instead of thinking logically and rationally, investors let past experiences, personal preferences and beliefs cloud their judgement when they make investing decisions. By understanding and addressing these psychological factors, investors can potentially improve their financial outcomes. Moreover, tools like a compound calculator and mutual fund lumpsum calculator can assist investors in visualizing the potential growth of their investments through the power of compounding. This can help them stay calm in the face of temporary volatility and stay invested to potentially meet their financial objectives. For example, using an SIP return calculator can help investors estimate the future value of their investments, providing clarity and aiding in better decision-making.

Yes, understanding behavioural finance can help investors make more rational choices. Recognising biases emotions, and the nature of behavioral finance allows for better decision-making and long-term financial success.
What are the two pillars of behavioural finance?
The two pillars of this discipline are cognitive biases and limits to arbitrage. Cognitive biases look at how emotions and decision-making patterns can lead to irrational financial behaviour. Limits to arbitrage looks at the constraints that prevent rational traders from correcting market inefficiencies caused by irrational investors.
How does behavioural finance differ from traditional finance theories?
Traditional finance assumes that investors are rational and markets are efficient. In contrast,this area of study recognises that investors are driven by emotional and psychological forces, which can lead to irrational financial decisions. Fear, overconfidence, loss aversion, mental short-cuts and other cognitive forces shape investors’ decisions, leading to anomalies and inefficiencies.
