97% of traders lose money. The problem is not the market, but what happens in our heads. There is a common belief that if we just learn a little more, identify the right pattern, or press the button at the right time, we will beat the market. The problem is that the data repeatedly tells a completely different story.
A comprehensive study published in 2020, which examined futures traders on the Brazilian index over more than 300 trading days, found a staggering statistic: 97% of traders lost money. Only 1.1% managed to earn more than the minimum wage, and even they experienced severe volatility along the way. The study included all traders who tried, not just those who survived, so it is not a 'survivorship bias'.
The market sends a clear message: short-term trading is a much harder business than most people think.
The biggest enemy is not the market
Almost all studies reach the same conclusion: traders' biggest threat is themselves.
Or, to be precise, their overconfidence.
Investors tend to believe they can predict short-term movements, execute more trades after successes, chase stocks that have already risen, and rush to take profits, while holding onto losses in the hope that 'it will come back'.
The result is confusion between activity and ability.
The market does not reward those who trade the most. It rewards those who make the best decisions over time.
The big question: how do we reduce errors?
Instead of trying to guess every market movement, one can build a process that reduces human error: 1️⃣Write a personal investment policy (which pre-defines asset allocation, risk level, and operating rules).
2️⃣Rebalance according to fixed rules, not headlines or emotions; studies by Vanguard and Morningstar found that systematic rebalancing can improve long-term returns and reduce the depth of drawdowns.
3️⃣Before any unplanned trade, wait 72 hours and write down why you are entering, what your exit point is, and what would make you admit you were wrong.
4️⃣ Annually calculate the 'behavior gap' – compare your portfolio's return as it would have been if you had not made any trades versus the actual return. For many investors, their own decisions, more than any market downturn, are what hurt returns.
The market does not guarantee profits, but it repeatedly punishes the same mistakes.
He who succeeds long-term is usually not the one who best predicts tomorrow, but the one who manages to control himself better than others.
Sometimes the most profitable trade is simply the one you didn't make.
