Why Understanding Human Behavior Matters in Trading

Understanding human behavior is important for getting the most out of trading and investing. This is because it can lead to more rational decisions and increase success.

Defining Trading Psychology

Trading psychology refers to the investor’s and trader’s emotions and how these play a role in affecting their trading decisions. Trading psychology is often used to rationalize trading behavior and understand how emotions like greed and fear drive investments and trades.
Behavioral finance, for example, is part of trading psychology and can be used to understand market outcomes and trading decisions better.

What Are Behavioral Economics?

To understand what behavioral finance is, it is crucial to know the term “behavioral economics,” especially in light of the fact that the former is considered a subfield of the latter.

Behavioral economics is a branch of psychology that looks at how people and organizations make economic choices. It combines insights from both psychology and economics to explain how certain economic decisions are made, particularly when they involve irrational behaviors.

Essentially, behavioral economics explores why some economic behaviors don't align with what traditional economic models predict.

What Is Behavioral Finance?

Simply put, behavioral finance extends the principles of behavioral economics to the realm of finance. It's a field of study that investigates how the psychology of traders, investors, and market participants can influence financial markets.

To accomplish this, it scrutinizes elements like psychological biases to understand and delve into irregular market trends, particularly those occurring in the stock market, such as significant spikes or declines in stock prices.

The Significance of Behavioral Finance

Behavioral finance can serve as a guiding principle for market participants as it can help them understand how certain decisions are made, it helps traders and investors make more informed decisions which can help limit losses. In addition, it helps them understand certain market outcomes and decisions, and draw conclusions accordingly. Finally, behavioral finance can also help traders and investors control their emotions and understand the power of psychology in trading and the financial markets.

Basic Principles of Behavioral Finance

Several fundamental tenets of behavioral finance assert that individuals involved in financial activities aren't entirely rational and disciplined; instead, they are subject to psychological influences and exhibit somewhat typical and self-regulating behaviors.

In addition, behavioral finance suggests that the financial decision-making process frequently hinges on the mental and physical well-being of the investor or traders. Moreover, changes in the market participant’s overall health typically correspond to shifts in their mental state. Consequently, this can affect decision-making and rationality across a range of real-world matters, including those specific to the field of finance.

The Psychological Aspects of Trading

As mentioned above, behavioral finance and trading psychology delve into the impact of biases, which are multifaceted and can often be categorized into five fundamental concepts and are used to analyze market outcomes and behaviors.

Some of the basic psychological aspects of trading, whether emotional influences or cognitive biases, include the following:

Experiential Bias / Recency Bias

As implied by its name, experiential or recency bias pertains to the encounters of market participants. Alternatively expressed, experiential bias arises from past events that can evoke certain memories.

For example, memories of events like market crashes can cause individuals to believe that similar events might happen again. Consequently, this perception may prompt many to avoid participating in the markets altogether or to exit trades and liquidate assets.

Familiarity Bias

This refers to when traders and investors become drawn to assets they’re familiar with. This can range from local corporations to local investments. Such bias leads to a lack of portfolio diversification, which increases trading risk. This is because when traders and investors diversify their portfolios (invest in different market assets), trading risk is often spread and diluted across different markets.

Confirmation Bias

We all hold certain beliefs that can be true or false. As such, confirmation bias refers to when traders or investors are biased toward certain information that adheres to their beliefs, irrespective of the validity of the information.

Loss-Aversion Bias

Loss aversion refers to an investor’s or trader’s tendency to prioritize avoiding losses over seeking gains. This preference, as a result, can lead to a greater focus on mitigating potential losses through higher payouts, potentially causing investors to avoid certain investments even if the associated risks are considered acceptable.

This is usually evident where investors or traders quickly sell off winning assets but hold onto losing ones in the hope of recovering losses. This can result in traders and investors avoiding the financial markets or making extremely cautious decisions to avoid losses rather than focus on potential gains.

Fear of Missing Out (FOMO)

FOMO refers to the anxiety stemming from the notion that if one doesn’t follow the crowd and enter into a currently popular trade or investment, they might miss out while others benefit. Such emotion can lead traders to make unsound and detrimental decisions.

Risk-Aversion Bias

This pertains to the tendency of traders and investors to place more emphasis on negative news over positive ones, resulting in overly cautious decision-making that prioritizes safe investment choices. Consequently, this inclination towards risk can carry more significance than the potential for reward.

Overconfidence Bias

Refers to when traders and investors hold the belief that they have better skills compared to others, which sometimes leads to making the wrong decisions.

Common Trading Mistakes

Numerous trading errors can result in losses, and while there's no black-and-white formula for avoiding them, traders should be aware of the following common mistakes.

  • Herd Mentality and Groupthink: Blindly following the crowd without rationalizing certain decisions or weighing up the possible repercussions can often lead to loss of capital or failed investments.
  • Anchoring and Confirmation Bias: As mentioned above, confirmation bias refers to holding certain beliefs without questioning or analyzing them, while anchoring refers to relying too much on initial information and basing decisions accordingly. When doing so, traders do not get the bigger picture of the financial markets, and it can lead them to make uninformed decisions.
  • Impulsive Trading and Overtrading: Impulsive trading and overtrading often refer to excessively buying or selling an asset based on emotions rather than research or reason.
  • Regret Aversion and Holding Losing Positions: Regret aversion is the avoidance of certain actions due to a fear of regretting them. This can be reflected in holding losing positions, for example.

Strategies for Overcoming Behavioral Biases

Some of the actions that can be taken to avoid certain behavioral biases that can lead to losing investments are as follows:

Understand Your Risk Tolerance and Setting Risk Management Tools

Pinpointing how much risk you’re willing and able to tolerate can help you control your emotions when trading, and avoid letting certain biases get in the way of progressing your trading skills.
In addition, risk management tools such as Stop-Loss or Guaranteed Stop can help you achieve your goals.

Create a Trading Plan

To navigate market uncertainty and avoid emotional trading, you can create a trading plan that can help you stay grounded in the face of volatility. Nonetheless, keep in mind that trading plans do not always work and may need to be altered sometimes.

Develop Emotional Intelligence

Reflect on your trading decisions and results in order to understand how you navigate the markets and learn how not to let your emotions control you. This can help you manage risk as well.

Psychological Tools and Techniques

Below are several psychological tools and techniques available for traders and investors to enhance their trading activities:

  • Mindfulness and Meditation: You can meditate and engage in mindfulness in order to reach a higher level of awareness while trading and investing. This will help you mitigate risk and avoid certain mistakes.
  • Cognitive Behavioral Therapy (CBT): In the context of trading, Cognitive Behavioral Therapy (CBT) entails recognizing and confronting detrimental thought patterns, encouraging a more logical and productive method for handling emotions and formulating trading decisions.
  • Visualization and Positive Affirmations: Positive affirmations and visualizing your desired results can help you reinforce more positive thoughts and decisions that bring about these outcomes.


In conclusion, behavioral finance and trading psychology highlight the role of our emotions in trading decisions. As such, being mindful of certain emotions and biases is crucial to your development as a trader. In addition, implementing risk management and trading plans, and learning about your risk tolerance and your emotions can help you accomplish your goals.
