Behavioral Biases in Finance – How Thinking and Emotions Affect Investment Decisions

In finance, it is expected that investors make rational (logical) decisions to earn maximum returns. However, in real life, investors often act irrationally due to biases in their thinking and emotions. These behavioral biases cause people to make poor financial decisions, leading to losses or missed opportunities.

Behavioral biases are mainly of two types:

1. Cognitive Errors – These happen due to mistakes in thinking or faulty logic. They can be corrected through learning and awareness.
2. Emotional Biases – These happen due to emotions like fear, greed, or attachment. They are harder to control because they come from personal feelings.

Understanding these biases is important for investors to make better decisions and avoid unnecessary risks.

1️⃣ Cognitive Errors – Mistakes in Thinking

Cognitive errors occur when people misunderstand information or use incorrect logic while making decisions. These biases lead to wrong judgments, but they can be reduced with proper education and awareness.

Examples of Cognitive Errors:

🔹 Confirmation Bias:

• Investors look for information that supports their existing beliefs and ignore contradictory facts.
• Example: A person believes a stock will perform well. They only read positive news about it and ignore negative reports.

🔹 Anchoring Bias:

• People rely too much on the first number or information they see and make decisions based on it.
• Example: A person sees a stock was priced at ₹1,000 last year and believes it is still valuable today, even if the company is not performing well.

🔹 Hindsight Bias:

• After something happens, people believe they “knew it all along,” even if they had no actual prediction.
• Example: After a stock market crash, an investor says, “I knew this would happen,” even though they never predicted it before.

🔹 Availability Bias:

• People give more importance to easily available information rather than actual facts.
• Example: A person invests in a company because they recently saw an ad about it, without researching its financials.

🔹 Framing Bias:

• Decisions are influenced by how information is presented rather than the real data.
• Example: A mutual fund ad says, “90% of investors made a profit,” and a person invests without checking if the returns were actually high or low.

✏️ Impact of Cognitive Errors:

• Investors make decisions based on limited or misleading information.
• They may hold onto bad investments due to past beliefs.
• Overconfidence in their knowledge leads to risky investment choices.

2️⃣ Emotional Biases – Decisions Based on Feelings

Emotional biases occur when fear, greed, or personal emotions influence investment decisions. Unlike cognitive errors, these biases are harder to control because they come from human nature.

Examples of Emotional Biases:

🔹 Loss Aversion Bias:

• People fear losses more than they value gains, leading them to avoid risk even when it is beneficial.
• Example: An investor refuses to sell a loss-making stock, hoping it will recover, even when better investment opportunities are available.

🔹 Overconfidence Bias:

• Investors believe they have better knowledge or skills than others and take excessive risks.
• Example: A trader makes too many transactions, believing they can always predict the market, leading to high fees and potential losses.

🔹 Regret Aversion Bias:

• Investors avoid decisions because they fear making a mistake and regretting it later.
• Example: A person does not invest in stocks, fearing they will lose money, even though long-term investment could be profitable.

🔹 Status Quo Bias:

• Investors prefer to do nothing instead of making necessary changes.
• Example: A person keeps money in a low-interest savings account instead of investing, even though they could earn better returns.

🔹 Endowment Effect:

• People think something is more valuable just because they own it.
• Example: An investor holds a stock longer than necessary, believing it is worth more than the market value, just because they own it.

✏️ Impact of Emotional Biases:

• Investors panic and sell stocks during market crashes, leading to losses.
• They miss good opportunities due to fear of regret.
• Emotional decisions reduce overall portfolio performance.

🔴 How Behavioral Biases Affect Investments?

Behavioral biases can lead to:
❌ Poor investment decisions – People choose stocks emotionally instead of logically.
❌ Excessive trading – Overconfident investors trade too much and lose money in transaction costs.
❌ Holding onto bad investments – Fear of loss makes people keep unprofitable stocks.
❌ Panic selling – Investors sell stocks in a market crash due to fear, missing out on future profits.

For example, during a stock market crash, many investors panic and sell their stocks at a loss. But after some months, the market recovers, and they regret selling too early.

✅ How to Overcome These Biases?

✔ Be aware of your biases – Learn about them and observe your behavior.
✔ Think long-term – Do not react to short-term market movements.
✔ Base decisions on data, not emotions – Always research before investing.
✔ Take expert advice – Financial advisors can help in making better choices.
✔ Have a structured investment plan – Follow a strategy instead of making impulsive decisions.

📌 Example of Good Investment Practice:
Instead of making emotional decisions, a smart investor:
✅ Sets long-term financial goals.
✅ Diversifies their portfolio (invests in different assets).
✅ Does not panic during market fluctuations.
✅ Regularly reviews their investments.

💡 Key Takeaway:
If you control your emotions and base decisions on logic, you can become a better investor and achieve financial success.
