The Base Rates — What Actually Happens to Retail Traders

Most trading education hides the outcome data or replaces it with folklore. This course puts it in lesson two, because trust is the product and because your decision to continue should be informed. Every number below names its dataset and its definition of 'losing' — those details change the number, which is exactly why sourceless statistics are worthless.

The strongest datasets

• Taiwan, every day trader in the market, 1992–2006: fewer than 1% of day traders predictably and reliably earned positive abnormal returns net of fees. In a typical year roughly 20% showed a profit — being up in some year and having persistent skill are very different claims.
• Brazil, everyone who began day trading index futures 2013–2015: of those who persisted more than 300 trading days, 97% lost money; only 1.1% earned more than the Brazilian minimum wage. Performance did not improve with experience.
• United States, 334 day-trading accounts during the 1998–99 bull market: about 35% were profitable — in the most favorable market imaginable, and profits tracked the Nasdaq's direction (that is exposure, not skill).
• European Union, regulator-collected CFD broker data behind the 2018 intervention: 74–89% of retail CFD accounts lose money. The UK regulator's 2016 sample: ~82% of clients lost, averaging about £2,200 per year.
• US discount brokerage, 66,465 households, 1991–96: the fifth who traded most earned 11.4% a year while the market returned 17.9% — a 6.5-point annual penalty, driven by costs.

Two honest nuances. First, 'everyone loses' is false: the Taiwan data shows a small tail of genuinely skilled traders whose profitability persisted year over year — the top-ranked earned meaningful returns even after fees. Second, that tail was identified looking backward across fifteen years of complete national data. Standing at the start, your justified estimate of joining it is on the order of one in a hundred — and feeling confident does not move that number, because the losing 99% were confident too.

Why lead with this?

• Because informed consent is the ethical minimum for a course that takes your money and your time.
• Because base-rate neglect — judging your prospects by the vividness of success stories rather than the frequency of outcomes — is itself one of the failure modes that sinks traders.
• Because a rational decision NOT to trade actively, made after seeing this data, is a success outcome of this course, and its final module treats it as one.
