How Many Day Traders Are Profitable? What the Studies Show

How many day traders are profitable: Published day-trader studies measure different markets, periods and samples, so there is no universal profitability percentage. Compare net-of-cost definitions and persistence separately from a selected winning period.

How Many Day Traders Are Profitable?

In the large studies that have measured it, a minority of day traders earn a profit after costs, and the share shrinks as the sample is limited to people who keep trading. There is no single percentage. Published figures run from roughly a third of a small broker sample down to about 3% of people who persisted for more than 300 days in one Brazilian futures market, and under 1% when the question is who reliably earns positive abnormal returns after fees. The answer depends on the market, the years, who is counted and what "profitable" means.

Key Takeaways

• No single number is right. The studies measure different things: a profit in one day, a profit in one year, a reliable profit across years, or an income above a salary benchmark.
• Taiwan, 1992 to 2006: about 20% of active day traders earned positive net abnormal returns in a given year, and fewer than 1% did so predictably and reliably after fees (Barber, Lee, Liu and Odean, 2014).
• Brazil, index futures: of individuals who started day trading in 2013 to 2015 and continued for more than 300 days, 3.0% had a positive net profit, and the share with a profit fell the longer people traded (Chague, De-Losso and Giovannetti).
• U.S., one day-trading firm, 1998 to 1999: about twice as many traders lost money as made money, and roughly 20% were more than marginally profitable (Jordan and Diltz, 2003).
• These are base rates for specific samples, not forecasts for you. They describe past markets and people. They do not test whether a plan, a tool or discipline changes the odds.

What the Main Studies Measured

The Brazilian paper also summarizes older work. It describes the Jordan and Diltz study as finding that 36% of its 324 traders profited net of fees.

Why the Percentages Disagree

1. The time window. In the Brazilian data, 29.8% of the 1,111 people who day traded for only one day had a positive net profit. The share was 15.5% for those who traded 2 to 50 days, 8.9% for 51 to 100, 6.8% for 101 to 200, 5.4% for 201 to 300 and 3.0% for more than 300. The same market and the same dataset give anywhere from 30% to 3% depending on how long a person is required to have traded.
2. Who is counted. Barber and colleagues start from about 450,000 individuals who day traded in an average year, and then look at the 277,000 who traded more than NT$600,000 (about US$20,000) a year. Occasional and frequent traders are different populations.
3. What counts as profitable. A positive result in a year, a positive result after adjusting for market returns, and a reliable result that repeats in the following year are three different bars. In the Brazilian sample, 3.0% had a positive net profit, 1.1% earned more than the minimum wage (about US$16 a day), and 0.5% earned more than a bank teller's starting pay.
4. Costs and taxes. The Brazilian study subtracts exchange and brokerage fees but not income taxes, platform fees or the cost of courses, and the authors say real results are likely worse. The Taiwan study includes commissions and the transaction tax on sales.
5. Instrument and era. Taiwanese stocks, Brazilian index futures and 1990s U.S. day-trading firms are not 2026 U.S. stocks. The Brazilian authors report that high-frequency traders' share of deals rose from 11.6% in 2012 to 41.9% in 2017, which is one reason the competitive landscape differs by period.

What the Studies Say About Skill and Learning

• Skill appears to exist, and is rare. In Taiwan, the 500 day traders ranked best in a given year went on to earn about 37.9 basis points a day after fees in the next year, and the worst-ranked earned about -28.9 basis points a day. The authors write that past performance was by a large margin the best predictor of future performance. This is a statement about a ranked group in hindsight, not a test you can run on yourself in advance.
• Experience did not clearly help in the Brazilian sample. Among the 1,551 persistent traders, the authors find expected daily profit was negative and did not improve with the number of days traded.
• Losers tend to quit, but many persist. In the Taiwan data, unprofitable traders were more likely to stop, and the 2017 working-paper version reports that more than 75% of day traders quit within two years. The published abstract reports that aggregate day-trader performance was negative.
• Regulators describe the same pattern qualitatively. The U.S. SEC's 2005 investor publication "Day Trading: Your Dollars at Risk" says that day traders typically suffer severe financial losses in their first months of trading and that many never reach profitability. It contains no percentages.

What These Studies Cannot Tell You

• Your odds. A sample average does not describe an individual. Different instruments, schedules, costs, risk limits and starting capital produce different outcomes.
• Whether a plan, a checklist or discipline changes the result. None of these studies tested an intervention. A written plan can support consistency; no study here shows it changes the probability of profit.
• Today's market. Many U.S. brokers now list commission-free stock trades, and market structure has changed since these samples. Spreads, slippage and data fees still apply.
• Round-number statistics you see repeated. Figures such as "90% of day traders lose" are widely repeated, but they are not the headline number of the studies above. Trace any statistic to a named study, market and year before repeating it.

How Much Do Day Traders Make?

The best-documented answer in these studies is not an income figure but a distribution with a lot of losses. In the Brazilian sample, of 1,551 persistent day traders, 47 had a positive net profit, 17 earned more than about US$16 a day, 8 earned more than about US$54 a day, and the top individual averaged about US$310 a day with a standard deviation of about US$2,560 a day. That is index futures in Brazil in 2013 to 2017 and cannot be converted into an expected income for a U.S. stock trader. The Taiwan study reports only a small group with reliable after-fee profit, and no typical salary.

A Hypothetical Illustration: Costs Against a Small Edge

Assume, hypothetically, that a trader makes 8 round trips a day in 200 shares and that spread, slippage and fees together cost $0.02 per share per round trip. That is 8 × 200 × $0.02 = $32 a day, or about $672 over 21 trading days, before any losing trade. The strategy has to earn more than that gross simply to break even, which is why measuring slippage and fees from your own fills matters more than the headline commission.

How to Use This Research

1. Treat the figures as a base rate. They describe the group, so judge a plan on your own recorded results after costs.
2. Measure in R and count costs. Record each trade's result as a multiple of the amount risked and subtract spread, slippage and fees. See the expectancy formula guide.
3. Wait for enough trades. A few dozen trades cannot distinguish skill from luck. See how many trades you need.
4. Size so a bad run is survivable. Read risk of ruin and maximum drawdown before you decide how much to risk.
5. Practice before risking money. Paper results are practice, not evidence of live results. The paper trading fills guide covers the gap.
6. Write rules down in advance. The day trading beginners guide and the day trading checklist are starting points, and the trading psychology guide covers the behavior side.

Frequently Asked Questions

What percentage of day traders are profitable?

There is no single percentage. In a Taiwanese study, about 20% of day traders were profitable after costs in a given year and fewer than 1% were reliably profitable year to year. In a Brazilian futures study, 3.0% of those who kept trading for more than 300 days had a positive net profit. Figures depend on the market, the period and the definition.

Is it true that 90% or 95% of day traders lose money?

Those round numbers circulate widely, but they are not the headline result of the main academic studies. The closest primary figures are the 97% of persistent Brazilian day traders who lost money in the Chague study, and the roughly two-to-one ratio of losers to winners in an older U.S. sample. Each applies to a specific market and period.

Can you make a living day trading?

In the Brazilian study, only 0.5% of persistent traders earned more than a bank teller's starting pay. In the Taiwanese data, a small group earned reliable profits after fees. Neither study estimates the odds for an individual today, and costs, taxes and risk of loss are real.

Do day traders get better with experience?

The evidence is mixed. The Brazilian authors found no sign of learning among traders who persisted for more than 300 days. The Taiwanese research finds that unprofitable traders are more likely to quit, and that a small group of traders is reliably profitable. Experience alone does not appear to ensure improvement.

How much do day traders make?

The studies do not report a typical income. In one Brazilian sample, the top individual averaged about US$310 a day with large day-to-day variability, while most persistent traders had a net loss. These results are for index futures in Brazil and do not translate to a U.S. stock trader.

Does paper trading tell me whether I will be in the profitable group?

No. Paper trading is practice for process and order handling. It does not include real fills, costs from slippage, or the pressure of losing real money, and it is too short a sample to estimate skill. Treat it as a way to test your rules and your ability to follow them.
