Why investors overestimate returns and underestimate risk

Why returns can be misleading and how to properly evaluate investment strategies through risk and sustainability
Why returns seem like the main metric
When choosing an investment strategy, investors most often focus on returns. This is understandable: the metric is clear, easy to compare, and directly tied to profit expectations.
However, this is also where the key mistake lies. Returns show the outcome but do not explain how it was achieved. Without analyzing risk, this metric provides an incomplete picture.
Where the misperception lies
In practice, investors tend to:
- focus on the best historical periods
- project past results into the future
- ignore drawdown periods
For example, high returns over a year are often perceived as a stable result. At the same time, the following factors are overlooked:
- the level of risk taken
- the depth and duration of drawdowns
- the dependence of results on market phases
As a result, investors evaluate not the strategy itself, but its most successful period.
Why risk is underestimated
Risk is harder to perceive for several reasons:
- it does not always materialize immediately
- during growth periods, it is barely noticeable
- it cannot be expressed by a single simple metric
Until risk materializes, it seems insignificant. That is why strategies with higher returns and hidden risk often appear the most attractive.
The illusion of stable returns
Special attention should be given to strategies with visually “smooth” returns.
At first glance, such performance appears to indicate stability. In practice, however, it may signal:
- shifting losses into future periods
- lack of loss realization
- aggressive position management
- accumulation of hidden risk
The absence of drawdowns in long-term statistics is not an advantage, but a reason for deeper analysis.
Returns and market phases
Any strategy operates in a changing market environment. Markets go through different phases:
- growth
- corrections
- sideways movement
- periods of uncertainty
High returns may be the result of favorable conditions rather than a robust strategy. It is during difficult periods that a strategy’s true resilience becomes evident.
Practical consequences
Underestimating risk leads to common investment mistakes:
- choosing overly aggressive strategies
- increasing investment volume without considering risk
- lack of diversification
As a result, even moderate market changes can lead to significant losses.
The approach of professional market participants
In professional environments, priorities are structured differently:
- risk is assessed first
- then the strategy’s robustness
- and only then returns
This approach helps avoid situations where high returns are achieved at the cost of excessive risk.
The IQ Security Fund approach
At IQ Security Fund, primary focus is placed on risk structure and strategy resilience.
Evaluation is conducted across several levels:
- risk control in each trade
- analysis of drawdowns and their duration
- assessment of return volatility
- strategy behavior under different market regimes
Returns are viewed as the result of this system, not as an end goal.
How investors can change their approach
For a more objective evaluation of a strategy, it is important to shift focus from returns to risk. In particular, investors should consider:
- the depth and frequency of drawdowns
- the stability of results
- the structure of returns
- performance under adverse conditions
Only a comprehensive analysis allows for well-founded investment decisions.
Conclusion
Overestimating returns and underestimating risk is one of the key causes of poor investment decisions.
Returns show potential profit, but risk determines the sustainability of results. In the long run, the ability to control risk becomes the decisive factor.
Frequently asked questions
Why do investors tend to overestimate returns and underestimate risk?
Investors typically focus on the best historical periods, project past results into the future, and overlook drawdown periods, so a strong return over one year gets perceived as stable even though the risk taken is ignored. This means investors evaluate a strategy's most successful period rather than the strategy itself. Risk is harder to perceive than return, since it does not show up immediately and stays barely noticeable during growth.
Why does risk feel insignificant until it actually happens?
Risk is hard to perceive for several reasons: it does not always materialize immediately, it is barely noticeable during growth periods, and it cannot be captured by a single simple metric the way return can. Until it materializes, risk seems insignificant, which is why strategies with higher returns and hidden risk often look most attractive. This gap between how risk feels and how it behaves is where poor investment decisions usually start.
Why can a visually smooth return curve actually be a warning sign?
A smooth looking return curve can signal losses shifted into future periods, losses not being realized, aggressive position management, or hidden risk quietly accumulating. The absence of drawdowns in long-term statistics is not an advantage, it is a reason for deeper analysis. High returns can also simply reflect favorable market conditions rather than a resilient strategy, and true resilience only shows during difficult periods.
How does IQSF evaluate a strategy differently from just looking at returns?
IQSF evaluates a strategy on several levels before looking at returns: risk control within each trade, the depth and duration of drawdowns, the volatility of returns, and behavior across different market regimes. Returns are treated as the outcome of this system, not a goal in themselves. This mirrors how professional participants generally work: risk first, then strategy robustness, and only then returns.
