The foundational assumption of standard finance is that human beings are rational when making financial decisions. This assumption posits that individuals carefully weigh the pros and cons of each situation before choosing the option that maximizes their self-interest. However, over the years, growing evidence has shown that human behavior in finance is often far from rational. This has led to the emergence of behavioural finance, which explores the psychological factors influencing financial decisions, shedding light on the biases that cause individuals to deviate from rationality.

Behavioural biases delves into the intricate psychological factors that sway financial decision-making. It uncovers the reasons why individuals do not consistently adhere to the rational choice models predicted by standard finance, attributing this inconsistency to various biases that can significantly impact personal investing. Few biases are mentioned below:
1. Anchoring Bias: Anchoring bias is a cognitive error that prompts individuals to anchor their decisions on outdated or irrelevant information. Investors afflicted with this bias may continue to hold losing stocks in the hope of reaching unattainable price levels based on obsolete data, thereby negatively affecting their portfolio performance.

2. Familiarity Bias: Familiarity bias leads investors to favor asset classes with which they are most familiar or possess more information. This inclination can result in a portfolio that is overly concentrated and may not align with their risk profile and investment objectives, leading to potential underperformance against benchmarks.

3. Mental Accounting: Mental accounting is the tendency to segregate money based on its source and intended use, influencing spending decisions. Individuals may be more willing to splurge on luxury items with windfall gains but choose to save earned income. This bias can significantly impact overall financial well-being.

4. Herd Mentality : Herd mentality drives investors to follow the crowd instead of conducting independent analysis. This behavior can lead to poor market timing and participation in speculative bubbles, with potentially dire consequences for financial portfolios.

5. Loss Aversion : Loss aversion instills a fear of financial losses, often leading to inaction. Investors may opt to hold onto losing stocks due to an aversion to realizing losses, even when evidence and analysis suggest that a different course of action would be more appropriate. This bias can hinder portfolio growth and limit opportunities.

Recognizing and addressing behavioural biases is crucial for making sound investment decisions. While these biases are inherent in human nature, several strategies can help mitigate their impact and promote rational decision-making.
1. Financial Planning: A comprehensive financial plan serves as a structured roadmap, offering clarity in decision-making. It outlines an individual’s current financial status and future goals, helping to reduce impulsive behavior and maintain focus on long-term objectives.

2. Emotional Control: Avoiding emotional decision-making is paramount. Emotions can cloud judgment, leading to suboptimal choices. Developing discipline and rationality in decision-making can help individuals overcome biases.

3. Financial Advisor: Working with a financial advisor provides access to objective advice and expertise in constructing a diversified investment portfolio tailored to individual goals and risk tolerance. Advisors can act as a valuable counterbalance to emotional decision-making.

Behavioural biases have considerable influence over financial decisions. Acknowledging these biases and employing strategies to counteract their effects is essential for making prudent investment choices. While biases cannot be entirely eliminated, individuals can become more aware of their impact and take steps to become more rational investors, ultimately improving their financial outcomes and achieving their long-term goals.
