What are the behavioural biases in the stock market?
Real traders and investors tend to suffer from
Behavioral finance can be analyzed to understand different outcomes across a variety of sectors and industries. One of the key aspects of behavioral finance studies is the influence of psychological biases. Some common behavioral financial aspects include loss aversion, consensus bias, and familiarity tendencies.
Here, we highlight five prominent behavioral biases common among investors. In particular, we look at loss aversion, anchoring bias, herd instinct, overconfidence bias, and confirmation bias. Loss aversion occurs when investors care more about losses than gains.
- Overconfidence Bias. Overconfidence is an emotional bias. ...
- Self-attribution Bias. ...
- Active Trading. ...
- Fear of Loss. ...
- Disposition Effect. ...
- Framing. ...
- Mental Accounting. ...
- Familiarity Bias.
Information-processing biases include anchoring and adjustment, mental accounting, framing, and availability. Emotional biases include loss aversion, overconfidence, self-control, status quo, endowment, and regret aversion.
To get us started, we have decided to focus on three; Endowment Bias, Loss Aversion Bias, and Anchoring Bias. (UPDATE: we've added three more: Overconfidence, Familiarity, and the Gambler's Fallacy).
Real traders and investors tend to suffer from overconfidence, regret, attention deficits, and trend chasing—each of which can lead to suboptimal decisions and eat away at returns. Here, we describe these four behavioral biases and provide some practical advice for how to avoid making these mistakes.
Some of the biases affecting financial decisions are confirmation bias, disposition bias, experiential bias, familiarity bias, loss aversion, mental accounting, and overconfidence.

For instance, a commodities investor may assume that the rise in Gold prices implies that Silver prices will also rise. Another example is a stock trader who may consider that the rising prices of one pharmaceutical company mean that another company in the same industry will also see its stock price appreciate.
Understanding Loss Aversion
The fear of realizing a loss can cripple an investor, prompting them to hold onto a losing investment long after it should have been sold or to offload winning stocks too soon—a cognitive bias known as the disposition effect.
There are well over 100 cognitive biases, an umbrella term that refers to types of errors in thinking that occur when we're processing and interpreting information. Think of them as mental shortcuts that help us make sense of the world and reach decisions quickly.
What is a behavioural bias? Behavioural biases are irrational beliefs or behaviours that can unconsciously influence our decision-making process. They are generally considered to be split into two subtypes – emotional biases and cognitive biases.
Some of the most common behavioral biases that contribute to market bubbles include: Overconfidence: People tend to overestimate their own abilities and knowledge, which can lead them to make risky investments that they would not make if they were more realistic about their abilities.
Behaviorally biased investors always take poor decisions about fund choice resulting in expenses and thereby poor performance. The investors are categorized based on various characteristics as gambler, smart, overconfident, narrow framer and mature.
The way you make money from stocks is by the selling them at a higher price than you bought them. For instance, if you bought a share of Apple stock at $200 and sold it when it reached $300, you would have made $100 (minus any taxes you'd have to pay on the money you made).
They are influenced by our background, personal experiences, societal stereotypes and cultural context. It is not just about gender, ethnicity or other visible diversity characteristics - height, body weight, names, and many other things can also trigger unconscious bias.
As an investor, selecting and adhering to your chosen asset allocation is job number one. Before you decide to buy an investment, ask yourself, "Will stock XYZ or fund ABC fit into my asset allocation and provide enough potential growth to justify its risk?" If not, it's not the investment for you.
