Financial media, trading platforms, and social communities amplify the visible winners while losses remain private, creating a survivorship-bias environment in which beating the market feels more achievable than the evidence warrants. The democratization of commission-free trading since 2019 and the rise of zero-days-to-expiry options have lowered the barrier to entry while raising the stakes, drawing in a new generation of retail traders who may underestimate how thoroughly institutional algorithms and market-makers harvest the other side of their trades.\n", "rough_estimate": "~50% lose money", "kind": "intuition" }, "native": { "display": "97% of persistent day-traders (active >300 days) lose money over a 5-year period (Brazil CVM cohort, Chague et al. 2020)", "numerator": 97, "denominator": 100, "unit": "share of individual day-traders active >300 days who lost money (5-year Brazilian futures cohort)", "population": "all individuals who day-traded mini-Ibovespa futures in Brazil, 2013–2015 cohort, followed through 2017" }, "normalized": { "lifetime_us_adult": 0.08, "display": "~1 in 13 US adults who try active retail trading experience significant financial loss over their trading career", "log_value": -1.097, "assumptions": "Two-factor estimate: (A) P(US adult becomes active enough to face meaningful day-trader risk) and (B) P(significant financial loss | active).

We use 10% as a conservative lifetime estimate for adults who trade actively enough to face the losses documented in the cohort studies. Factor B: The Chague, De-Losso, and Giovannetti (2020) Brazil CVM cohort found 97% of persistent day-traders (>300 days active) lost money over five years.
