Top 15 Cognitive Biases to Avoid Failure in Trading

As a trader, you are always looking for ways to improve your performance and increase your profits. One factor that can greatly impact your success is cognitive biases. These biases are inherent in all of us and can lead to poor decision-making when it comes to trading. In this blog, we will discuss what cognitive biases are and how they affect investing. We will also delve into the top 15 cognitive biases in trading that commonly make traders’ lives harder, such as confirmation bias, loss aversion bias, and herd mentality bias (aka jump on the bandwagon effect). Additionally, we will provide strategies on how to overcome these biases and make better trading decisions. So, whether you’re a beginner or an experienced trader, read on to learn how to avoid failure in investing by understanding and overcoming cognitive biases.

What are Cognitive Biases and How Do They Affect Trading?

Simply put, cognitive biases are errors in thinking that can lead traders astray. These biases can manifest in different ways, from confirmation bias to loss aversion bias and beyond. Unfortunately, these mental shortcuts can lead traders to make poor decisions that ultimately result in losses. Even the best traders still have to deal with their cognitive biases.

Cognitive Bias Definition

When making decisions, humans use mental shortcuts called cognitive biases. These biases can cause us to make mistakes in judgment, leading to poor decision-making. There are many different types of cognitive biases, including confirmation bias, recency bias, and availability heuristic. Confirmation bias is the tendency to seek out information that confirms our existing beliefs, while recency bias occurs when we give more weight to recent events over past data. Availability heuristic happens when we make decisions based on readily available information rather than considering all relevant data. By understanding these biases and how they affect our decision-making process, traders can avoid making costly mistakes and improve their overall performance.

Top 15 Cognitive Biases to Avoid Failure in Trading

Trading biases are essential for every trader to understand because they can lead to irrational decision-making, resulting in a substantial financial loss on the basis of systematically wrong decisions about the stock market. The Top 15 Cognitive Biases mentioned in this blog includes Confirmation bias, Anchoring bias, Gambler’s fallacy, Overconfidence bias, Herd mentality, Sunk cost fallacy, FOMO (Fear Of Missing Out), Loss aversion bias, Recency bias, Availability heuristic, Self-attribution bias, Hindsight bias, Illusory superiority bias, Selective perception bias and Optimism Bias. Understanding these biases helps traders make informed decisions our frontal cortex rather than our ancestral brain.

Confirmation Bias

This cognitive bias involves seeking out information that confirms one’s existing beliefs while dismissing contradictory information. Traders who exhibit confirmation bias may make investments based on incomplete or biased information, leading to suboptimal outcomes. An example is ignoring bad news such as rising interest rates when you are in a long position on the S&P 500. To overcome confirmation bias, traders should actively seek out opposing viewpoints and evidence and remain open-minded when analyzing market trends and financial data.

Gambler’s Fallacy

The gambler’s fallacy is the belief that past events can influence future outcomes even when they are unrelated. For instance, some traders may assume that because a stock has been consistently rising in the past, it will continue to rise in the future regardless of other factors. This bias clouds judgment and leads to poor decision-making based on faulty assumptions.

Traders should focus on objective data and analysis rather than relying on gut feelings or past performance. They should explore various factors related to their investments, such as market trends, economic indicators, and company performance before making informed decisions.

Loss Aversion Bias

Many traders exhibit Loss-Aversion Bias, which is the tendency to prefer avoiding losses rather than acquiring gains. This bias can cause traders to hold onto losing trades for too long or avoid taking necessary risks. To overcome this bias, it’s essential for traders to focus on their long-term goals and develop a disciplined trading plan that includes risk management strategies. By doing so, traders can keep their emotions in check and make more objective decisions based on data and analysis rather than fear of loss.

Sunk Cost Fallacy

Traders who face losses may be tempted to hold onto their positions, hoping for the market to turn around. This is known as the Sunk Cost Fallacy, and it can lead to significant losses if not recognized early. By focusing on past investments, traders may overlook the present state of the market and ignore new information. To avoid this bias, it’s important to make decisions based on current information rather than past losses. Traders who recognize and address their cognitive biases can improve their ability to make objective and profitable decisions.

Recency Bias

Recency bias s the tendency to give more weight to recent events or information and to ignore long-term trends. This can lead to impulsive decision-making and poor risk management, as traders may make decisions based on short-term market fluctuations rather than long-term market trends. To avoid recency bias, it’s important for traders to focus on data-driven analysis and to consider long-term trends when making investment decisions. By doing so, traders can develop a more objective perspective, make informed decisions, and improve their overall trading performance.

Hindsight Bias

This bias occurs when traders believe they would have predicted or anticipated an event after it has already occurred. It can lead to overestimation of one’s abilities, which in turn can result in poor investment choices.

An example of hindsight bias in trading would be looking back on a stock’s performance and believing that it was an obvious buy or sell at the time, even though it may not have been so clear at the time of the decision. To avoid this bias, traders should focus on analyzing trends and data objectively and avoid relying too much on subjective beliefs or emotions.

Availability Heuristic

The availability heuristic refers to the tendency of individuals to rely on readily available information when making decisions. This can lead to overestimating the probability of an event occurring, based on recent news or events, and underestimating the likelihood of more common events. For instance, traders might make hasty decisions based on an article they read in a newspaper or magazine, without taking into account long-term market trends. To avoid falling prey to this bias, it’s important to seek out multiple perspectives and sources and consider historical data while analyzing market trends.

Herd Mentality

Herd mentality is the tendency for people to follow the actions or beliefs of a larger group, even if it goes against their own instincts. This bias can lead to irrational decision-making and ultimately result in financial losses. Examples of herd mentality in investing include following popular trends, seeking comfort in the consensus view, or blindly trusting the advice of others without conducting independent research. Warren Buffet certainly doesn’t fall victim to this bias. He is consistently looking to invest in undervalued companies.

To avoid falling victim to herd mentality, traders should stay informed and make independent decisions based on objective analysis. It’s important to develop a strong understanding of market fundamentals and maintain emotional discipline.

Anchoring Bias

Anchoring bias occurs when an individual relies too heavily on the initial piece of information they receive, the anchor, even if it’s no longer relevant. For example, a trader might fixate on a stock’s historical performance instead of considering its current market conditions.

To avoid falling victim to anchoring bias, traders must be open to changing their perspectives based on new data and seek out multiple sources of information. It’s also essential to focus on current market trends and conditions rather than past performance.

Narrative Fallacy

Narrative fallacy occurs when traders create a story or narrative around market events, even if there is no clear relationship between cause and effect. This can lead to poor investment decisions based on subjective interpretations rather than objective analysis. Examples of narrative fallacy include attributing market movements to specific events or personalities, forming opinions based on incomplete information, and ignoring objective data.

To avoid the pitfalls of narrative fallacy, traders should focus on data-driven analysis and avoid making assumptions based on incomplete information. It’s important to remain aware of the ways in which our own cognitive behaviors can impact our decision-making processes, and to prioritize objective analysis over subjective narratives.

Representativeness Heuristic

Essentially, traders who fall victim to this tend to make judgments based on how closely something matches their preconceived expectations or stereotypes. This can cause them to overlook important information or make decisions based on incomplete or inaccurate data. For instance, a trader might assume that a particular stock will perform well because it belongs to a popular industry – even if there’s no real evidence to support this belief.

To overcome the influence of the representativeness heuristic, it’s crucial for traders to gather as much information as possible before making a decision. Weighing all available evidence and avoiding assumptions based on incomplete data can be effective strategies for combating this particular cognitive bias.

Status Quo Bias

The status quo bias can be a significant obstacle for traders to overcome. It’s natural for people to prefer things to stay the same and avoid change, but in trading, this can be bad. Traders who are unwilling to make changes to their strategies or try new approaches could find themselves stuck in a losing position, unable to adapt to market conditions.

To avoid falling prey to the status quo bias, it’s essential for traders to regularly evaluate their strategies and be willing to make changes when necessary. This requires a willingness to step outside of one’s comfort zone and take calculated risks.

Blind Spot Bias

Blind spot bias can lead traders to overlook their own biases and assume they are more objective than they actually are. This can result in overconfidence in their abilities, underestimating risks, and ignoring evidence that contradicts their beliefs. Blind spot bias can lead to poor trading decisions and significant financial losses. The best way to avoid blind spot bias is to actively seek out diverse perspectives and consider alternative viewpoints before making decisions. Regularly reviewing past trades and evaluating the reasoning behind them can also help identify potential biases.

Selection Bias

Traders may unintentionally limit their sample to only successful trades or use data from a specific time period that does not accurately represent overall market trends. This can lead to inaccurate conclusions and poor decision-making. To avoid selection bias, traders should aim to use a diverse and random sample that represents the larger population. By doing so, they can make more informed decisions based on accurate and unbiased data, which is essential for success in trading. It’s important to remember that unbiased data analysis is crucial for avoiding trading mistakes due to cognitive biases.

Negativity Bias

Negativity bias makes a trader more inclined to the negative side of a trade instead of considering both the positive and negative sides of a trade. The impact of such a bias is that a trader could forego an entire strategy because of the negative aspect when they only need to make a small adjustment to the strategy to turn the trade into a profit.

What are Strategies for Overcoming Trading Biases?

Overcoming trading biases is crucial for success in the financial markets. Traders who are aware of their cognitive biases can learn to detach from emotions and make rational decisions based on facts. Staying informed and educated about market trends, diversifying portfolios, sticking to a well-defined trading plan, and implementing proper risk management techniques can also help overcome biases. Regularly reviewing past trades and learning from both successes and failures is essential for improving performance.

Final Thoughts

In conclusion, cognitive biases are a significant hurdle that traders must overcome to achieve consistent success in the market. By being aware of the potential pitfalls and actively working to mitigate their effects, traders can make more informed and objective decisions based on reliable data. It takes discipline, patience, and continual education to develop the necessary skills to navigate the complex world of trading successfully. Ultimately, by recognizing patterns and developing a trading strategy grounded in rational decision-making, traders can avoid common pitfalls and build long-term success in the market.
