Many legendary traders are celebrated as “Market Wizards.”
But how can we tell whether an extraordinary track record truly reflects skill, or whether it could simply emerge from randomness?
To explore this question, imagine a large group of investors trading the market over many years.
Suppose none of them has any particular skill. They invest in stocks largely driven by intuition or gut feeling.
Even in such a world, probability tells us something remarkable: when enough participants are involved, a small number will inevitably end up with spectacular performance.
This observation becomes even more relevant in environments where many traders compete and are evaluated over relatively short periods of time, sometimes just a single year.
In our study, we simulate exactly this situation.
Thousands of investors start with identical conditions and trade over time with no informational advantage.
We then analyze the distribution of outcomes and focus on the traders who end up at the very top of the performance ranking.
What we find raises an important question about how we interpret exceptional track records in financial markets.
The full analysis and results of the experiment are available here.
