Data Sources & Citations
In continuous editorial use since 2012.Trading World Champion selections are anchored in publicly verifiable data. Every reported performance figure is cross-checked against at least one independent third-party source before publication. This page documents those sources, their roles in the verification process, and the relative weight given to each.
1. Trading competition data
1.1 World Cup Trading Championships (worldcupchampionships.com)
Operator: Robbins Trading Company (Chicago, IL). Years: Since 1984. Audit standard: Independent broker-audited trade-by-trade results.
The World Cup Trading Championships (WCTC) is the longest-running independently audited live trading competition in the world. Participants trade real capital in real brokerage accounts; results are tracked at the broker level and audited by Robbins' independent compliance process. Final standings are published publicly at worldcupchampionships.com.
Trading World Champion uses WCTC results as the primary verification source for competition-track candidates. Champions whose primary verification source is the WCTC include:
- Paul Skarp (2015) — Futures Division Champion, 219.1% audited return
- Artur Teregulov (2016) — Futures Division Champion, 914.8% audited return
- Kevin McCormick (2021) — Futures Division Champion, 253.8% audited return
- Paul Skarp (2025) — Futures Division Champion, 256% audited return
The WCTC is also the secondary verification source for the 2023 champion Darren O'Neill for his 2025 division placements (Annual Forex 4th, Q3 Forex 5th, October Monthly Forex 1st).
1.2 US Investing Championship
A separate live trading competition focused on equities and ETFs, also operated by Robbins Trading Company. Used as a secondary verification source for equity-track candidates. Verifiability standard is the same as the WCTC.
2. Hedge fund performance databases
2.1 BarclayHedge
One of the longest-running hedge fund and managed futures performance databases. Aggregates monthly performance reports from thousands of registered hedge funds and CTAs. Trading World Champion uses BarclayHedge to cross-verify hedge fund return figures appearing in audited investor letters.
Note: BarclayHedge data is self-reported by funds but is subject to internal consistency checks. Where BarclayHedge return figures differ from audited fund letters, the audited letter is the authoritative source.
2.2 HFR (Hedge Fund Research)
Performance index provider with one of the most comprehensive hedge fund databases. Used for cross-verification of fund returns and for benchmarking individual fund performance against strategy-class indices. Champions whose performance has been cross-verified against HFR include:
- Bill Ackman (2014) — Pershing Square 40.4% return cross-checked against HFR Activist Index
- Chase Coleman (2017) — Tiger Global ~34% return cross-checked against HFR Long/Short Equity Index
- Chris Hohn (2019) — TCI 41% return cross-checked against HFR Activist Index
- Rob Citrone (2024) — Discovery 52% return cross-checked against HFR Macro Index
2.3 eVestment
Institutional-class hedge fund database used by allocators. Used as a tertiary cross-verification source for the largest hedge funds in the rankings.
3. Audited investor letters
Quarterly and annual audited letters from major hedge funds are a primary verification source for fund managers in the rankings. Letters are sourced from public filings, SEC EDGAR (for letters that reference SEC-registered entities), and from established financial media archives that publish letters with permission.
Examples of investor letters used in past selections:
- Appaloosa Management investor letters (2012, 2013) — David Tepper's audited fund performance
- Renaissance Technologies disclosure (2018) — Medallion Fund's net-of-fees return
- Pershing Square investor letters (2020) — Bill Ackman's COVID-hedge documentation
- Citadel investor communications (2022) — Ken Griffin's record $16B profit year
Where investor letters disagree with database figures (BarclayHedge, HFR, eVestment), the audited letter is treated as authoritative.
4. SEC filings
4.1 Form 13F
Quarterly disclosure of equity holdings by institutional managers with $100M+ in assets. Used to verify position-level claims in champion profiles where applicable, particularly for activist investors and concentrated-equity managers.
Champions whose position-level claims have been cross-verified against 13F filings include Chris Hohn (TCI), Bill Ackman (Pershing Square), Chase Coleman (Tiger Global), and Ken Griffin (Citadel).
4.2 Form 13D / 13G
Disclosure of 5%+ activist or passive equity stakes. Used for verifying activist campaigns referenced in champion profiles.
4.3 Form ADV
Annual filing by registered investment advisers, including AUM, regulatory history, and disciplinary disclosures. Used for AUM verification on hedge-fund champions.
5. Independent trader verification
5.1 AuditedTrader.com
Independent third-party audit verification platform for individual traders. Audits broker statements, calculates risk-adjusted metrics (Sharpe, Calmar, drawdown), and publishes a verified performance record.
AuditedTrader.com is the primary verification source for the 2023 champion Darren O'Neill's historical track record (2020-2025). His audited multi-year performance there is the basis for the consistency criterion in his 2023 selection.
6. Financial media as cross-verification
The following financial media are used as secondary cross-verification sources, not as primary data sources. Their role is to triangulate against database and audit figures, and to surface context (signature trades, year-end commentary, manager interviews) that informs the qualitative editorial deliberation.
- Bloomberg — year-end hedge fund coverage, manager interviews
- Reuters — hedge fund earnings reporting, AUM disclosures
- Institutional Investor — long-form profiles, year-end rankings, methodology articles
- Hedge Fund Alpha — performance reporting, manager-of-the-year coverage
- Wall Street Journal / Financial Times — major-trade coverage, regulatory filings analysis
- Investopedia — methodology references for ratio definitions
7. Ecosystem cross-references
Trading World Champion's editorial selections are cross-checked against independent third-party records rather than any single source: competition administrators (Robbins Trading Company / World Cup Trading Championships), fund-performance databases (BarclayHedge, HFR), SEC 13F and 13D filings, audited investor letters, and audited broker statements.
8. Verification standards by champion-type
| Champion type | Primary source | Cross-verification | Verifiability score |
|---|---|---|---|
| Hedge fund manager | Audited investor letters / SEC 13F | BarclayHedge, HFR, financial media | Highest |
| Competition winner | WCTC / USIC audited results | Broker statement, financial media | Highest |
| Independent trader (audited) | AuditedTrader.com | Broker statements, competition results where applicable | High |
| Independent trader (un-audited) | Self-reported with broker evidence | Live execution recordings, contemporaneous public posts | Moderate (typically excluded) |
| Anonymous claims | None | None | Not eligible |
9. What we do not use
- Social media performance claims — YouTube, X/Twitter, Instagram, TikTok performance claims are not eligible regardless of follower count or stated confidence. The medium offers no verification mechanism.
- Backtested or simulated returns — only real-capital trading is considered.
- Marketing-page returns — figures published on a fund's or trader's marketing page that are not corroborated by an audited source are not eligible.
- Selectively reported windows — if a candidate's only available verified data is a particularly favourable subset of their full track record, the verification standard treats this as moderate-to-low.
