Investing is never a straightforward journey. Even the most experienced investors will face situations where their decisions do not yield the expected outcomes. It’s easy to say that we should learn from our mistakes, but understanding what constitutes a mistake in investing can be more complicated than it seems. Are poor short-term returns from a long-term position a genuine fault, or are they just meaningless noise? Misinterpreting what an investing mistake is can be as damaging as ignoring the mistakes altogether. This article explores three common types of investing mistakes — belief mistakes, process mistakes, and outcome mistakes — and provides guidance on how to avoid them.
Understanding Investment Belief Mistakes
The first and perhaps the most common investing error is a mistake of belief. This occurs when the foundational investment philosophy or strategy is flawed. For example, if you adopt an approach designed to tactically allocate across asset classes based on short-term predictions, the likelihood of underperformance is high. Often, investors react by tweaking their processes or adjusting their inputs, but if the underlying belief is incorrect, such changes will not help.
Belief mistakes happen when we wrongly assume that our investment strategy is reasonable and achievable, often due to overconfidence or incentives that encourage risky behaviour. The real challenge with these errors is that they are hard to change; altering one’s investment beliefs can feel like tarnishing one’s reputation or admitting to a failure of identity. To minimise belief mistakes, it’s essential to base your investment approach on sound principles and be willing to revise them if proven wrong.
Process Mistakes: A Flawed Approach
Even if your investment beliefs are solid, process mistakes can still occur. These errors happen due to flaws in the way you implement your investment strategy. A technical process mistake might involve a weakness in your analysis or the way you use information. For example, if you believe you can achieve a specific financial goal, like losing weight, but fail to design a proper diet and exercise plan, your process is flawed.
Behavioural process mistakes are equally significant. They involve underestimating your limitations and emotional reactions. For instance, an investor may have a robust plan but fail because they can’t stick to it — perhaps they panic during market downturns or give in to the temptation of short-term gains. Both individuals and institutions are prone to these errors, which emphasises the importance of creating a supportive decision-making environment that reinforces the desired approach.
Outcome Mistakes: When Good Decisions Yield Poor Results
One of the toughest parts of investing is accepting that even the best decisions don’t always lead to the desired outcomes. The financial markets are unpredictable, and luck can often play a significant role. Talented investors may experience bad luck that makes them look foolish or, conversely, see poor decisions appear brilliant in hindsight.
Outcome mistakes are particularly dangerous because they can lead us to abandon sound strategies due to perceived failures. There are four key types of outcome mistakes:
- Bad luck: Sometimes, despite careful planning, events beyond your control lead to poor results.
- Goal mismatch: This occurs when you measure your results against the wrong benchmarks, such as focusing on short-term performance when you have long-term objectives.
- Cost of sensible diversification: Diversification may mean holding investments that seem like mistakes in the short term but are necessary for long-term stability.
- Natural failure rate: Even with solid beliefs and a good process, some level of failure is inevitable. Recognising this helps avoid unnecessary overhauls of your approach.
To mitigate outcome mistakes, investors should clearly define their beliefs and expectations and maintain a long-term perspective. Documenting decision-making processes and avoiding hindsight bias are also crucial in navigating these challenges.
Avoiding Common Investing Pitfalls
Many investors make mistakes that reduce returns and increase anxiety. Three common pitfalls include:
- Trying to Time the Market: Investors often attempt to time the market to avoid downturns, but accurately forecasting market movements is nearly impossible. Research shows that missing even a brief period of strong market performance can significantly affect long-term returns. Rather than trying to predict when to buy or sell, it is more effective to hold a globally diversified portfolio and stay invested. For example, consider the performance of the Russell 3000 Index: A $1,000 investment in 1999 grew to $6,449 over 25 years, but missing the best days drastically reduced returns.
- Focusing on the Headlines: It’s easy to be swayed by media attention or recent performance, particularly when it comes to popular stocks like the “Magnificent 7” (Alphabet, Amazon, Apple, Meta Platforms, Microsoft, NVIDIA, and Tesla). However, many stocks that outperform initially often fail to sustain that momentum. Diversifying your investments across sectors and geographies can reduce overall risk and position you to capture returns from future top performers.
- Chasing Past Performance: Many investors select funds based on past returns, expecting them to continue outperforming. However, data shows that most funds do not maintain top performance over consecutive periods. Instead of relying on past performance, it’s better to build a diversified, research-backed investment strategy aligned with your long-term goals and risk tolerance.
The Importance of Professional Advice
While avoiding these mistakes can improve your chances of reaching your financial goals, managing your investments alone can be challenging. A qualified financial adviser can offer deeper insights, help you avoid costly mistakes, and design a diversified strategy tailored to your needs. By providing guidance through different market conditions, an adviser can encourage the discipline necessary for building wealth over time.
