Behavioral Finance: Unveiling the Psychology Behind Investment Decisions

 Over the last few decades, behavioral finance—a branch of behavioral economics shaped by economic psychology—has gained recognition in both the academic and financial worlds.  Behavioral finance offers a road map to assist everyone in making more informed financial choices by illustrating the ways and reasons why behavior shifts from logical expectations.

What is Behavioral Finance?

Behavioral finance, a branch of behavioral economics, stipulates that investors and financial professionals' financial activities are influenced by psychological factors and biases. Furthermore, biases and influences are possible explanations for a variety of market anomalies, particularly those related to the stock market, like sharp increases or decreases in stock prices.

Traditional Financial Theory

Let us first explore traditional financial theory as we try to gain a better understanding of behavioral finance. Traditional finance is based on a number of fundamental ideas. It begins by assuming that the marketplace and investors are completely rational and base their decisions on information that is readily available, as well as their logical analysis. 

Additionally, it asserts that investors prioritize utilitarian qualities; in other words, they try to maximize their financial gains. 

Moreover, traditional finance maintains that investors have perfect self-discipline and composure and are capable of making disciplined and consistent decisions. Lastly, it makes the assumption that investors can evaluate and act upon financial data without prejudice or error since they are not impacted by cognitive or information-processing issues.

Behavioral Finance Theory

Behavioral finance is the economic theory that sheds light on frequently illogical and impractical financial behavior, such as excessive credit card spending or panic trading during a market drop. 

Rather than treating investors as "rational," behavioral finance views them as "normal," admitting that they are not perfect. Behavioral finance acknowledges that investors are subject to their own biases and are prone to cognitive errors that result in incorrect judgments, in contrast to the presumptions of traditional finance. 

This viewpoint emphasizes the human aspect of financial decision-making, stressing the importance of emotions and psychological variables in investor behavior. People usually make their financial decisions based more on emotion than reason.

The History of Behavioral Finance

The book "Psychology of the Stock Market," written by George Seldon in 1912, is when the idea of behavioral finance first emerged. But in the 1970s and 1980s, the work of economist Robert J. Shiller and psychologists Amos Tversky and Daniel Kahneman helped popularize and promote the idea. They applied widespread, deeply ingrained, subconscious heuristics and biases to the process of financial decision-making.

It was suggested by Daniel Kahneman and Amos Tversky that most investors don't actually choose the best option objectively; instead, they typically base their judgments on subjective reference points.

Subsequently, Richard Thaler popularized the concept of "mental accounting," which holds that people's perspectives on their finances vary depending on the purpose of their money, such as retirement or college savings. 

In the course of time, their research served as a foundation for the study of behavioral biases surrounding finance and cognitive psychology, the two areas that play a major role in behavioral finance today.

Understanding Behavioral Finance Biases

The impact of biases is one of the most significant insights in behavioral finance analysis. There are several causes of bias. Identifying and categorizing various forms of behavioral finance biases might be crucial when focusing on the examination or evaluation of sector or industry outcomes.

1. Self-attribution Bias: 

 In behavioral finance, there is a natural tendency to credit our talent for positive results and pure luck for negative ones. In other words, we pick how to credit the outcome of our financial choices as per our convenience and liking.

2. Confirmation Bias

The tendency of investors to accept information that supports their preexisting beliefs about an investment is known as confirmation bias. Investors are quick to accept information as soon as it becomes available, even if it contains errors, as long as it validates their investment decision.

3. Overconfidence Bias

In numerous domains, most people typically overestimate their talents. Overconfidence in one's knowledge of the market or a particular stock can lead to impulsive shifts such as trying to time the market—that is, attempting to determine when it is ideal to purchase or sell stocks—or excessively investing in high-risk equities, which carry a higher chance of losing money.

4. Representative Bias

The false notion that there is a greater correlation between two objects or occurrences than there actually is. It happens when individuals become confused about the likelihood of an occurrence due to the apparent similarity of things or events. 

5. Experiential Bias

An experience bias arises when investors' perceptions of recent occurrences skew their judgment or give them the impression that the event is far more probable to recur.

6. Anchoring bias

Attaching a spending level to a specific reference is known as anchoring. Allowing your initial impression of a price or figure to unreasonably shape your thoughts.

People in sales, for instance, make use of anchoring by kicking off negotiations way above market value. When the price drops, it will appear like a wonderful deal because the inflated price acts as an anchor.

7. Loss Aversion

When investors give more weight to their fear of losses than to their appreciation of market gains, it is known as loss aversion. Stated differently, individuals are comparatively more inclined to prioritize preventing losses over realizing returns from their investments.

Some investors may therefore desire larger payouts to make up for their losses. Regardless of whether the investment's risk is rationally acceptable, they may want to prevent losses entirely if a high payout is unlikely.

8. Framing Bias

When people base their decisions not just on the facts themselves but also on how the information is presented to them, this bias is known as framing bias. People may reach different conclusions or make different decisions based on the same data provided in two distinct ways. In the field of behavioral finance, an investor's response to a given opportunity can vary based on how it is presented to them.

9. Familiarity Bias

The familiarity bias occurs when investors favor assets that they are familiar with, such as stocks of domestic firms or locally held businesses. Consequently, investors lack diversification across various industries and investment categories, thereby not effectively mitigating risk. Generally speaking, investors stick with assets they are familiar with or are acquainted with.

10. Herd Behavior

According to herd behavior, individuals frequently imitate the financial habits of the herd as a whole. In the stock market, herding is well-known for causing rapid rallies and sell-offs.

Wrapping Up

A branch of behavioral economics known as "behavioral finance" proposes that individuals are not essentially as rational as traditional finance theory suggests when it comes to financial decisions like investing. A fascinating explanation and description of how emotions and biases affect stock values may be found in behavioral finance, which can prove to be a useful tool for investors.

The field of behavioral finance is expanding. Behavioral finance offers a roadmap to assist us in making better, more logical financial decisions by analyzing how and when people shift from rational expectations.

Behavioral finance is being actively incorporated into client interaction strategies and business models for financial advisors. Behavioral finance is becoming more and more important as the foundation of an investing strategy for asset managers, financial analysts, and the investment process itself.
