Humans with emotions have a long history of making reckless decisions, some which might cause them serious grievance and some which guide them to make disastrous financial decisions. Behavioral finance is one such field, it relates to the psyche of investors and its role in financial decision making.

One such scandal in the history of human financial disasters was the Tulip Mania of 1637

Imagine this: the Dutch, in all their pragmatic glory, suddenly decided that tulips, yes, those delicate and colorful flowers, were the hottest commodity in town. By the early 1630s, the demand for tulips skyrocketed. Prices of tulip bulbs surged to insane levels, with some rare varieties costing more than a year’s salary of a skilled worker. People sold their homes, livestock, and anything else they could part with, all in the hopes of cashing in on this floral frenzy.

Behavioral Biases at Play

Here’s where behavioral finance enters the garden. Tulip Mania perfectly illustrates several key psychological biases:

1. Herd Behavior: As more people jumped on the tulip bandwagon, others followed suit, fearing they’d miss out on easy profits. It’s like a 17th-century version of FOMO (Fear of Missing Out). The irrational exuberance was contagious, and the market was driven by the “wisdom” of the crowd, which in reality, was anything but wise.
2. Overconfidence Bias: Investors believed they were making sound decisions based on the “inevitable” rise in tulip prices. The reality? They were speculating on something as unpredictable as the weather. This overconfidence led to excessive risk-taking and ultimately, financial ruin for many.
3. Greater Fool Theory: The market was driven by the belief that no matter how high the prices went, there would always be a “greater fool” willing to pay more. Spoiler alert: the supply of fools eventually ran out, and those left holding the bulbs found themselves in a thorny situation.

This phenomenon is not only seen in stock markets and real estate but also prominently in multi-level marketing (MLM) schemes and Ponzi schemes.

In MLM schemes, participants earn money by recruiting others into the program, rather than through the sale of products. The model collapses when the pool of new recruits (the “greater fools”) runs out, leaving the majority of participants with financial losses. This is similar to Ponzi schemes, where returns are paid to earlier investors using the capital from newer investors. Eventually, the supply of new investors dwindles, leading to the scheme’s inevitable collapse.

Countries like the United States, India, and China have witnessed large-scale MLM operations and Ponzi schemes. For example, Bernie Madoff’s Ponzi scheme in the U.S. defrauded investors of billions, while India has seen several high-profile MLM frauds, such as the SpeakAsia scam. China’s crackdown on MLMs highlights the global nature of these financial traps.

All these schemes rely on the same flawed premise as the Greater Fool Theory: the belief that there will always be someone willing to buy at a higher price or invest at the promise of high returns. When the supply of new participants dries up, the market crashes, leaving latecomers with significant losses.

The Pop

The bubble inevitably burst in February 1637, when, during a routine bulb auction, buyers suddenly vanished. Panic ensued, and tulip prices plummeted overnight. The market crashed, leaving speculators with worthless bulbs and a harsh lesson in economic reality.

But in the utopian universe of Adam Smith where rationality prevails, we invest and make financial decisions based on Traditional finance, but what exactly is Traditional Finance?   Imagine a world where every investor is a perfectly rational Vulcan from Star Trek, devoid of emotions and always making decisions that maximize their wealth. Traditional finance is that utopia. It rests on the lofty assumption that all investors have access to all available information, process it without bias, and act purely in their best economic interests. Concepts like the Efficient Market Hypothesis (EMH) tell us that markets are always right, prices reflect all known information, and everyone is a miniature Warren Buffett.

But Unfortunately, things are not all that rosy, there enters Behavioral Finance, the pesky little sibling who constantly pokes holes in the grandiose visions of traditional finance. Behavioral finance says, “Hold up, humans are actually more like emotional rollercoasters than rational robots.” It introduces the wild world of cognitive biases, where overconfidence leads investors to believe they are the next financial gurus, and herd behavior turns the stock market into a chaotic stampede reminiscent of Black Friday shopping.

Lucky for you folks, the concept of behavioral finance does not exhaust here, let’s get an insight into some of the key concepts of behavioral finance 

1. PROSPECT THEORY : The psychology behind Risky Decisions 

Developed by Daniel Kahneman and Amos Tversky in 1979, Prospect Theory revolutionizes our understanding of decision-making under risk. Unlike traditional finance, which assumes people act rationally, Prospect Theory delves into the quirky and often irrational human psyche.

Key Elements:

1. Value Function: People perceive gains and losses differently. The pain of losing $100 is more intense than the joy of gaining $100, making the value function steeper for losses.
2. Loss Aversion: Losses hurt roughly twice as much as gains feel good. This bias explains why investors might irrationally hold onto losing stocks, hoping they’ll rebound.
3. Probability Weighting: People overestimate small probabilities and underestimate large ones. This is why lotteries are popular despite the low odds of winning.
4. Reference Points: Decisions are made relative to a reference point, not in absolute terms. If you expect a $1,000 bonus but get $500, you feel worse than if you expected nothing and got $500.

Applications:

• Finance: Explains stock market bubbles and why people make poor investment decisions.
• Marketing: Marketers frame losses to influence consumer behavior effectively.
• Policy Making: Helps design better interventions by considering human biases.

   II.     MENTAL ACCOUNTING : 

Mental accounting, a concept introduced by Richard Thaler, refers to the cognitive process by which people categorize, budget, and evaluate their finances in separate “accounts” in their minds. This behavior often leads to irrational financial decisions because individuals treat money differently based on its origin, intended use, or mental categorization rather than considering its overall utility​ 

Key Aspects:

1. Segregation of Funds: People might save for a vacation while carrying credit card debt, treating these funds as separate even though paying off debt would be more financially prudent.
2. Budgeting Heuristics: Individuals allocate money into various categories (e.g., groceries, entertainment) and may refuse to transfer funds between them, even if one category is overspent.
3. Windfall Gains: Money received unexpectedly (e.g., bonuses or gifts) is often spent more freely than regular income, as it’s mentally categorized as less important.

Examples:

• Spending vs. Saving: Treating a tax refund as “extra” money to splurge rather than saving or investing it.
• Investment Decisions: Keeping investments separate, such as a “risky” stock portfolio versus a “safe” savings account, even when a holistic approach might yield better results.

        III.    Confirmation and Experiential Bias :  

1. Confirmation Bias 

It is the tendency to search for, interpret, and remember information that confirms one’s preexisting beliefs while disregarding or minimizing contradictory evidence. In the realm of finance, this bias can lead investors to:

1. Selective Information Gathering: Investors may seek out news and data that support their investment choices, ignoring warnings or negative information. For example, a stockholder might focus on positive earnings reports while ignoring signs of an impending market downturn.
2. Overconfidence: By reinforcing existing beliefs, confirmation bias can lead to overconfidence, where investors overestimate their knowledge and decision-making abilities.
3. Market Bubbles: When many investors collectively ignore negative signals, it can contribute to the formation of market bubbles. The 2008 financial crisis, partly fueled by the collective dismissal of the housing market’s instability, exemplifies this.

Experiential Bias

B.  Experiential Bias, also known as availability bias, occurs when individuals make decisions based on readily available information or recent experiences rather than considering all relevant data. Key characteristics include:

1. Recent Events Overemphasis: Investors may overemphasize recent market trends or personal investment outcomes. For example, after experiencing a market rally, investors might irrationally expect continuous growth, leading to risky investments.
2. Personal Anecdotes: Decisions are often influenced by personal stories or experiences. If an investor has recently profited from a particular stock, they might irrationally assume future investments in that stock will be equally profitable.
3. Neglect of Probabilities: This bias can lead to misjudging the likelihood of rare events. For instance, an investor who has never experienced a market crash might underestimate its probability, leading to inadequate risk management.

Recommendations for Sound Investing 

• Evaluate Long-Term Health: Stock markets have short memories. A company performing poorly now might improve in the coming quarters. Always consider the overall health of the company’s balance sheet and its long-term prospects before making investment related decisions.
• Avoid Borrowing to Invest: Families and individuals should spend within their budgetary limits. Avoid borrowing money to invest, as this can lead to a vicious cycle of debt and financial stress if investments do not perform as expected.
• Start Small and Learn: Begin by investing small amounts. Educate yourself about various investment options, market trends, and financial instruments. This approach helps you gain experience without exposing yourself to significant risk.
• Consider Risk and Reward: Always keep the risk-reward ratio in mind. Understand your risk tolerance and invest in assets that align with your financial goals and risk appetite. Diversifying your investments can help manage risk effectively.
• Use Mock Portfolios: Before committing real money, practice with mock portfolios. This allows you to test investment strategies and understand market dynamics without the risk of financial loss. Over time, this experience can guide your actual investment decisions and help diversify your risk.

Behavioral finance unveils the irrational quirks driving our financial decisions, from the speculative frenzy of Tulip Mania to the biases outlined in Prospect Theory. Understanding overconfidence, mental accounting, and confirmation and experiential biases sheds light on why we so often follow the herd. Recognizing these patterns helps investors navigate the complexities of the market more wisely. Embracing the lessons from behavioral finance empowers us to make more informed, rational, and ultimately profitable decisions.
