Entrepreneurs Up2Date - The Most Common Investor Mistakes and How to Avoid Them
Investing can be a powerful tool for building wealth, but it is also an area full of pitfalls. Many of these pitfalls stem from our own human psychology.
In this article, we review the most common investor mistakes and offer practical tips to avoid them.
Introduction to Behavioral Finance
Behavioral Finance is an economic theory that attributes the irrational behavior of individuals who make financial choices to psychological factors or biases. The latter can often explain all types of market anomalies and specific financial market behavior. The theory came about in response to the efficient market hypothesis (EMH) which states that - in a highly liquid market - all stock prices are valued efficiently based on all available public information. However, many studies have documented long-term historical phenomena in financial markets that contradict the EMH and cannot be believably represented in models based on perfect investor rationality. In general, theories of “behavioral finance” have also been used to provide clearer explanations for major market anomalies such as bubbles and deep recessions.
Emotions and preconceptions are bad advisors. It is therefore important to be aware of these emotions and to know and prevent common fallacies.
Emotional pitfalls
1. Overconfidence: The illusion of control
Many investors tend to overestimate their own capabilities. They think they can beat the market when the reality is different. The conviction that you can control the results when that is not the case creates a certain amount of hubris.
Example: An entrepreneur who is successful in his business can wrongly assume that this success automatically translates into success in investing.
How to avoid:
- Set realistic goals, act accordingly, and accept that markets are unpredictable.
- Inquire before you start investing and keep investing in better information, training and advice.
2. Loss aversion: fear of loss
Loss aversion or “loss aversion” occurs when investors give greater weight to caring for losses than to enjoying market gains. In other words, they're far more likely to try to give a higher priority to avoiding losses than making investment profits. After all, losing hurts more than winning.
This can lead to irrational decisions, such as holding on to underperforming investments for too long in the hope of recovering losses.
When we apply loss aversion to investing, we see the so-called disposition effect where investors sell their winners and hold on to their losers, unfortunately a common investor mistake.
Example: An investor refuses to sell an underperforming stock despite clear signs that the outlook is dim. And this is purely because he does not want to realize the loss.
How to avoid:
- Set clear sales rules in advance: If a company reveals negative things that weren't familiar with your purchase decision, dare to sell.
- Dare to admit that you made an investment mistake. Don't focus on your own entry price, it is often misused as an anchor point.
3. Herd behavior: walking with the crowd
It's tempting to follow popular trends, especially when you hear and read that “everyone” is investing in a particular sector or stock. However, this can lead to buying at the peak and selling during moments of panic. It is notorious in the stock market as the cause of dramatic bubbles and subsequent crashes. Super investor Warren Buffett puts this nicely: “be anxious when others are greedy and greedy when others are anxious”.
Example: During a hype, such as the technology bubble in 2000, many investors step in without understanding the underlying value of the assets.
How to avoid:
- Do your own research and understand what you're investing in.
- Build a diversified portfolio that matches your risk profile and goals, not those of others.
4. Short-term thinking and emotional decisions
Short-term declines in prices can lead to panic selling, while sharp rises can lead to overconfident buying.
This market volatility can trigger emotions like fear and greed, leading to irrational decisions. Fear can keep you from investing, while greed can encourage risky speculation. Investors who are overly focused on the short term have a higher risk of making emotional decisions. Stock market movements are completely unpredictable in the short term, while they do grow along with economic growth and inflation rates in the long term.
Example: An investor sells his shares during a temporary market decline while setting long-term investment goals.
How to avoid:
- Set up a long-term plan and stick to it regardless of daily market fluctuations. Make decisions based on facts and strategy, not emotions.
- Don't review your portfolio too often; once a quarter is often sufficient.
- Automate your investments with a periodic investment plan.
Cognitive pitfalls
In addition to the emotional pitfalls, there are cognitive pitfalls, which are the result of fallacies. In theory, they are called biases or “biases.” The most common ones are:
1. Confirmation bias: looking for what you want to hear
Investors tend to seek information that confirms their existing beliefs and ignore conflicting information. This can lead to a tunnel vision and poor investment decisions.
Example: Someone who believes tech companies will always grow ignores warnings about overvaluation and economic risks.
How to avoid:
- Actively listen to different points of view and seek counter-arguments.
- Consult an independent financial advisor to identify blind spots.
2. Hindsight bias: I knew it!
Hindsight bias is the tendency to believe that you could have predicted the outcome of an event after it has already occurred. This can lead to overconfidence and poor future decisions.
Example: After a fall in the stock market, an investor says, “I knew this would happen,” even though he did not take any action beforehand.
How to avoid:
- Keep an investment journal where you record your decisions and the reasons for them.
- Reflect on your mistakes without considering the outcome “inevitable”.
3. Self-attribution bias: attributing success to yourself
Self-attribution bias means that investors attribute their successes to their own ability, while attributing setbacks to external factors or bad luck rather than ignorance. This can lead to overconfidence and a lack of self-reflection.
Example: An investor who makes a profit in a bull market thinks it's because of his smart decisions, while the market as a whole is simply performing strongly.
How to avoid:
- Evaluate your results in the context of the market as a whole.
- Actively seek feedback and be honest about your performance.
4. Framing: how information is presented
The way information is presented can influence investment decisions. Positive framing can make investors overconfident, while negative framing can lead to unnecessary caution.
Example: A consumer is more likely to choose yoghurt that is 80% fat-free than the same yoghurt that contains 20% fat, although both mean the same thing.
How to avoid:
- Analyze numbers and information objectively, without being influenced by the presentation.
- If information seems too one-sided, ask for additional details.
5. Lack of diversification
A portfolio that relies too heavily on a particular investment strategy, sector, region, or asset class is more at risk. Diversification helps to diversify this risk.
Example: An entrepreneur only invests in real estate because he is familiar with it, and ignores other options such as stocks or bonds.
How to avoid:
- Diversify your investments across sectors, regions, and asset classes.
- Include assets or strategies that do not or do not follow a benchmark.
Conclusion: take control of your emotions
Investing isn't just a matter of numbers and analysis; it's also a mental challenge. By understanding the principles of “behavioral finance” and being aware of your own pitfalls, you can make better decisions and increase your chances of success.
Summary Tips:
- Acknowledge your own limitations and be aware that your humanity can influence your return.
- Invest for the long term and ignore short-term fluctuations. It is not the timing of the market, but the time in the market that is at play.
- Avoid emotional decisions with a disciplined approach or be guided for most of your assets.
- Diversify your portfolio and stick to your strategy.
Successful investing requires discipline and self-reflection. By being aware of how psychology affects your decisions, you can avoid pitfalls and pursue your investment goals more confidently.
If you are unable to control your emotions, think in time to call in an external advisor such as Value Square.
