The World's #1
The single largest company in the world
The #1 company globally by market cap. Quarterly review with full-quarter confirmation. Changes occur on the third Friday of March, June, September, and December.
Custodios Index publishes seven positional indexes. Six meet our strict performance criteria; a seventh — CI-WORLD500 — is published as our broadest, lowest-volatility positional benchmark for investors who prioritize diversification over concentration premium.
We analyzed 100 candidate positional indexes. Six met our strict performance criteria (Sharpe above 0.70 with meaningful alpha over the S&P 500). We publish a seventh — CI-WORLD500 — as our broadest, lowest-volatility positional benchmark. It prioritizes diversification and stability over maximum risk-adjusted return, serving investors who want the widest positional exposure.
The performance criteria we filtered by:
The complete analysis is documented in our Research section below — including the candidates that did not meet our criteria. We publish both what we built and what we considered.

Conventional wisdom treats volatility as something to minimize. For investors with appropriate horizons and discipline, the opposite is true. Volatility is what creates the opportunity to acquire more units at better prices over decades.
Modern portfolio theory equates volatility with risk. Lower volatility indexes are marketed as 'safer.' Higher volatility indexes are marketed as 'riskier.' This framing is useful for investors with short time horizons or those who cannot tolerate drawdowns psychologically.
But for the investor with a 20-year, 30-year, or multigenerational horizon — and the discipline to maintain regular contributions through market cycles — volatility is not a penalty. It is the mechanism that allows capital to compound efficiently.
Here is why.
When a high-volatility index falls 30%, the disciplined investor's monthly contribution purchases approximately 43% more units at lower prices. When the index recovers, those additional units compound at the full subsequent return. Over decades, this asymmetry transforms volatility from a drag into an accumulator.
A simple example. An investor contributing $1,000 monthly over 15 years (total: $180,000) would have accumulated, based on historical performance:
| CI-WORLD3 (vol 26.3%) | ≈ $1,742,000 |
| CI-WORLD10 (vol 23.0%) | ≈ $1,156,000 |
| CI-WORLD100 (vol 16.9%) | ≈ $785,000 |
| S&P 500 (vol 16.0%) | ≈ $535,000 |
| MSCI World (vol 15.0%) | ≈ $412,000 |
| CI-WORLD500 (vol 14.85%) | ≈ $548,000 |
The investor who 'took on more volatility' accumulated more than three times the capital of the 'conservative' approach — despite both starting with the same total contribution and the same time horizon.
The volatility was not lost capital. It was capital that compounded faster, because contributions during drawdowns purchased more units that then participated in recoveries.
Custodios Index publishes indexes across the volatility spectrum precisely because investors have different time horizons and disciplines. CI-WORLD3 is structured for the patient compounder. CI-FUTURELEADERS is structured for the investor who prioritizes stability. Both are valid, for different objectives.
This perspective is not aligned with most institutional marketing, which sells low-volatility products as universally superior. We publish this analysis because we believe transparency about how volatility actually behaves over long horizons is more useful than comfortable framing.
Past performance — real or simulated — does not guarantee future results. This documentation is analytical, not advisory.
Volatility is not risk. Risk is mismatch between strategy and investor.
This distinction creates a psychological advantage traditional investing cannot offer — and turns volatility into opportunity.
When you hold a Custodios Index index, you own a position in the global ranking, not a specific company. When the top-ranked company falls 30%, you are not asking whether that company's future is intact — you are seeing a discount on global market leadership itself. The position remains valid regardless of which corporation occupies it.
This frees the long-term investor to act decisively during fear.
Custodios Index indexes are designed for a combined strategy that traditional low-volatility products cannot support:
Concentrated indexes (CI-WORLD1, CI-WORLD3, CI-WORLD10) experience these windows more frequently due to higher volatility. Far from being a weakness, this frequency is the feature: more drawdowns mean more entry opportunities for the disciplined investor who combines steady DCA with opportunistic deployment.
Diversified indexes (CI-WORLD100, CI-WORLD500) experience fewer and shallower windows, offering stability for investors who prefer it.
This is why our catalog spans the full volatility spectrum. The concentrated indexes reward the patient, opportunistic compounder. The diversified indexes serve those who prioritize smoothness. Both are valid — for different temperaments and time horizons.
This is documented analysis of how the indexes behave, not investment advice. Past performance does not guarantee future results. See /legal.
Of the 100 indexes we analyzed, seven became official (six performance-tier winners plus CI-WORLD500 as broad benchmark). Below are the remaining candidates we checked — every variant tested, grouped by family, with the metric that disqualified each one. Full transparency, not a curated highlight reel.
¿Live también? No por ahora. Los 6 oficiales tienen constituyentes definidos año por año en la base de datos, lo que permite reconstruir la serie en vivo desde Yahoo. Los 94 candidatos son configuraciones de investigación con métricas de backtest archivadas — no tienen baskets versionados, por eso aparecen como tabla histórica y no como serie diaria. Si quieres uno específico en vivo, define sus constituyentes y lo movemos al catálogo oficial.
Why show indexes we didn't choose? Because rigorous analysis means documenting what didn't work, not only what did. Scientific papers report negative results. An index provider with integrity reports the candidates considered and rejected.
These indexes are NOT part of Custodios Index's official offering. They are documented here as transparency about our research methodology.

Custodios Index will continue analyzing positional configurations over time. If a new candidate emerges that meets our three criteria — outperformance, Sharpe above 0.70, and structural defensibility — we will evaluate it for inclusion in the official catalog.
The barrier is high by design. Seven is enough for now.
