Hypothetical backtested performance for the seven Custodios Index families, plus approximate historical reconstructions for our most concentrated positions.
Understanding our performance data
Custodios Index has not yet operated live. All performance figures shown are hypothetical backtests — simulations of how each index would have performed had it existed, applying our published methodology to historical market data.
We present data in two tiers of reliability:
ROBUST (2010–2025): Global market-capitalization data is comprehensive and reliable from 2010 onward. Our 15-year backtests rest on this solid foundation.
APPROXIMATE (pre-2010): For our most concentrated indexes (CI-WORLD1, CI-WORLD3, CI-WORLD10), the world's largest companies were well-documented for decades prior to 2010, allowing extended historical reconstruction. However, this pre-2010 data is approximate and may contain gaps, ranking inaccuracies, or methodological limitations. It is provided for illustrative context only and should not be relied upon.
All figures are hypothetical, unaudited, and subject to revision. Past performance — whether actual, backtested, or hypothetical — does not guarantee future results.
15-year backtest (2010–2025)
Based on reliable global market-cap data. Hypothetical backtest, not live track record.
| Index | Holdings | CAGR 15y | Vol | Sharpe | Max DD |
|---|---|---|---|---|---|
| CI-WORLD1 | 1 | 26.50% | 30.00% | 0.75 | -45.00% |
| CI-WORLD3 | 3 | 27.83% | 26.29% | 0.91 | -42.00% |
| CI-WORLD10 ★ | 10 | 24.65% | 23.05% | 0.90 | -38.00% |
| CI-DECILE1 | 150 | 20.58% | 17.63% | 0.94 | -32.00% |
| CI-WORLD100 | 100 | 17.57% | 16.86% | 0.80 | -30.00% |
| CI-FUTURELEADERS | 75 | 16.36% | 15.74% | 0.79 | -28.00% |
| CI-WORLD500 | 500 | 14.00% | 14.85% | 0.67 | -25.00% |
Hypothetical backtest applying Custodios Index methodology to 2010–2025 global market data. All indexes equal-weighted with index-specific caps, quarterly rebalancing. Sharpe calculated with 4% risk-free rate. Not audited. Not a live track record.
Extended historical reconstruction (approximate)
For concentrated indexes where the world's largest companies were historically documented. Pre-2010 data is approximate.
| Index | ~Period | CAGR (approx) | 15y robust (ref) | Data quality |
|---|---|---|---|---|
| CI-WORLD1 | ~1990–2025 (35y) | [APROX — VERIFICAR]% | 26.50% | Approximate pre-2010 |
| CI-WORLD3 | ~1995–2025 (30y) | [APROX — VERIFICAR]% | 27.83% | Approximate pre-2010 |
| CI-WORLD10 | ~2000–2025 (25y) | [APROX — VERIFICAR]% | 24.65% | Approximate pre-2010 |
The throne changes. The position endures.
The world's most valuable company has changed many times. The position #1 has always existed — and always mattered. This illustrates the core thesis: you buy positions, not companies.
| Era | Approx. #1 by global market cap |
|---|---|
| Late 1980s | Japanese firms (NTT and large banks, during the asset bubble) |
| 1990s | General Electric, Microsoft, Exxon |
| 2000s | General Electric, Exxon, PetroChina (briefly at 2007 IPO) |
| 2010s | Apple, ExxonMobil |
| 2020s | Apple, Microsoft, NVIDIA |
Notice what happened to the companies that once held the throne. Many are no longer leaders. Some are diminished. But an investor holding "the #1 global position" was never betting on any single company's permanence — only on the enduring value of global market leadership itself, whoever holds it.
This is the essence of positional indexing: companies are mortal, positions are eternal.

Important performance disclosures
HYPOTHETICAL PERFORMANCE. All performance data on this page is hypothetical and backtested. Custodios Index has not operated live. No actual portfolio achieved these results. Hypothetical performance has inherent limitations: it is calculated with the benefit of hindsight, does not reflect actual trading, does not account for fees, taxes, transaction costs, slippage, or liquidity constraints, and may be subject to overfitting.
APPROXIMATE HISTORICAL DATA. Figures presented for periods before 2010 are approximate reconstructions based on incomplete historical data. They may contain material errors and are provided solely for illustrative and educational purposes. They must not be relied upon for any decision.
NO AUDIT. None of the figures on this page have been independently audited or verified by a third party. Independent verification is planned as part of future institutional development.
NO GUARANTEE. Past performance, whether actual, simulated, backtested, or hypothetical, does not guarantee or indicate future results. Future market regimes may differ materially from historical periods. The 2010–2025 period in particular coincided with exceptional concentration in mega-cap leadership, which favored positional strategies; this may not persist.
NOT INVESTMENT ADVICE. Nothing on this page constitutes investment advice or a recommendation. Custodios Index publishes methodologies and data for research and benchmarking purposes only. See /legal for complete disclaimers.
ERRORS AND OMISSIONS. While reasonable efforts are made to ensure accuracy, Custodios Index and Custodios Group LLC make no warranty as to the completeness or accuracy of any data presented and disclaim liability for any errors or omissions.
