Day Trading Statistics (2026)

The single most-quoted fact about day trading is true, and the research behind it is unusually strong. Across the three best datasets, most day traders lose money: 70% of a sampled US brokerage's accounts, more than 80% of Taiwanese day traders in a typical six-month period, and 97% of Brazilians who stuck with it beyond 300 days (see the chart below).

These are not opinion pieces. They are peer-reviewed studies tracking hundreds of thousands of real traders over many years, net of the fees and taxes that actually reduce returns.

Four studies do the heavy lifting, and they agree (see the table below). The Barber, Lee, Liu, and Odean papers tracked the entire Taiwan Stock Exchange from 1992 to 2006, one of the richest trading datasets ever assembled. Chague and colleagues followed nearly 20,000 new Brazilian futures traders. The 1999 NASAA report examined US day-trading firm accounts directly.

Different countries, different decades, different instruments, same conclusion: day trading is, for almost everyone, a losing activity after costs.

The Brazilian study is the most sobering. Of 1,551 people who day-traded index futures for more than 300 days, 97% lost money net of fees. Just 47 turned any net profit, only 17 (1.1%) earned more than the minimum wage, and only 8 (0.5%) beat a bank teller's starting salary (see the table below).

The single most successful trader averaged US$310 a day, but they were one person in 1,551. And the authors note the real picture is worse: their figures ignore income taxes, platform costs, and the fees people pay for day-trading courses.

Most people who start day trading stop almost immediately. Among nearly 20,000 new Brazilian traders, 5.7% traded for a single day and more than half quit within 50 days; fewer than 8% persisted beyond 300 days (see the chart below).

That fast washout is itself a finding: the people who quit are not a random sample, they are the ones who lost money quickly, which means loss rates measured on survivors understate how badly the average newcomer does.

The Taiwan data shows the same attrition on a longer horizon. After one month, 97.5% of day traders are still active; after a year, 44%; after two years, 24%; and after three years, just 15% (see the chart and table below).

More than three-quarters of all day traders are gone within two years. The activity does not build a durable base of profitable professionals; it churns through a large population, most of whom leave poorer.

In any given year, about 13-15% of Taiwanese day traders earned a profit net of fees, which sounds survivable. But year-to-year consistency is what separates skill from luck, and there fewer than 1% (roughly 1,000 of 360,000) were reliably, predictably profitable (see the table below).

Even the most-favorable profile could not overcome the odds: a trader in the 75th percentile on every predictive characteristic still had only about a 25% chance of net profit. The house edge, transaction costs and taxes, is simply too large for most to beat.

A tiny group does make money. The top 500 Taiwanese traders earned +49.5 basis points a day gross and +28.1 net, with a respectable daily Sharpe ratio of 0.21. They account for about 10% of all day trading and clearly have genuine skill.

But they are 500 people out of 360,000, and identifying them in advance is nearly impossible. For everyone else, active day traders in aggregate earned +13.1 bps a day gross and -6.8 net: profitable before costs, unprofitable after them.

A hopeful theory is that traders improve with practice. The data rejects it. In Brazil, profitability did not rise with the number of days traded; the relationship was flat to negative.

Aggregate day-trader performance net of fees was negative in every single one of the 15 years Taiwan was studied. Experience did not turn the average trader into a winner; it mostly gave them more time to lose.

If losing is so common, why do people persist? Because behavior barely responds to results. Among traders with 50+ days of experience, the previously-profitable came back to trade 96.4% of the time over the next year, and the previously-unprofitable came back 95.3% of the time (see the table below).

Losers keep trading at almost exactly the same rate as winners. The pull of the activity, and the overconfidence that drives it, overwhelms the feedback from a shrinking account.

Day trading is a large share of volume but a small share of people. In Taiwan it exceeded 20% of total exchange dollar volume, and 97.5% of it came from individual retail investors (see the table below).

It is also highly concentrated: roughly 1% of individuals accounted for about half of all day trading. A small, hyperactive minority generates the bulk of the churn, and bears the bulk of the losses.

The losses add up to real money at a national scale. A companion study estimated that individual investors' trading losses in Taiwan equaled about 2.2% of the country's GDP, or 2.8% of total personal income, each year.

Framed as a return penalty, the aggregate individual-investor portfolio underperformed by about 3.8 percentage points a year, most of it flowing to institutions, market makers, and the government via transaction taxes.

There is no modern, public US dataset on the scale of the Taiwan or Brazil studies. The strongest US primary source remains the 1999 NASAA report, which found 70% of a day-trading firm's sampled accounts lost money and just 1 of 26 was a genuinely successful day-trading account, though the sample was small.

Widely-circulated figures like "95% of day traders lose" or "only 1-4% are profitable" trace to secondary aggregators citing FINRA surveys, not a primary FINRA or SEC study. We flag them as secondary; the robust numbers are the academic ones above.

The math is unforgiving. Day trading is close to zero-sum before costs and negative-sum after them: every trade pays a spread, a commission (historically), and a tax, and those frictions compound across hundreds of trades a year.

It also runs straight into the timing problem documented across all investing: the market's biggest gains cluster in a handful of days, and traders who move in and out routinely miss them. For nearly everyone, a diversified buy-and-hold portfolio beats trading, not because trading is impossible, but because the costs and the odds are stacked against it.
