What is Behavioral Finance?

Behavioral finance explores how psychological influences and cognitive biases affect financial decision-making. Traditional finance assumes that investors are rational and markets are efficient, but behavioral finance reveals that emotions and biases often lead to irrational investment decisions. By understanding these behavioral tendencies, we can better grasp why people make certain financial choices, such as overreacting to market movements or holding onto losing stocks for too long.

Key Concepts of Behavioral Finance

  • Overconfidence Bias

    • 🧠 Investors often overestimate their knowledge or ability, leading them to make overly risky financial decisions.

    • Example: A trader might believe they can predict the stock market's next move, taking bigger risks than they should.

​

  • Loss Aversion

    • 📉 People are more sensitive to losses than gains, leading them to avoid selling losing investments, hoping they will recover.

    • Example: Holding onto a stock that’s been losing value, rather than selling it to avoid further losses.

​

  • Herd Behavior

    • 🐑 Investors tend to follow the crowd, buying or selling assets based on what others are doing, rather than on rational analysis.

    • Example: A sudden rush to buy Bitcoin because it’s trending, without understanding the market fundamentals.
