A systematic approach to investing in the US market.

Fully data-driven. No human bias. Designed for stability and long-term outperformance.

Traditional research and analysis make it practically impossible to consistently beat the stock market index over time.
A DIFFERENT APPROACH WAS REQUIRED.

Autonomous Fund Management (AFM) is driven by mathematics, not human judgment. Covering the entire S&P 500—rather than concentrating on just 20-30 popular stocks—it delivers a safer, fully diversified investment approach.

AFM-managed accounts have outperformed the S&P 500 every year since 2019.

Investment management without human emotion.

AFM is a Swiss-developed, data- and mathematics-driven investment procedure operating directly in the investor’s own brokerage account.

Why Choose AFM?

Data-Driven

A procedure, not a portfolio manager.

AFM replaces forecasting, opinions and discretionary reactions with a disciplined autonomous process based on data, mathematics and systematic execution.

Broader Diversification

AFM includes all 500 companies in the S&P 500, providing broad market coverage and reliable long-term growth.

Safety First

What AFM deliberately avoids:
  • No human intervention in investment decisions
  • No market timing based on news or sentiment
  • No margin trading
  • No short selling
  • No derivatives, futures or options

Consistent Growth

AFM has outperformed traditional large-cap funds over time by staying systematic and avoiding emotional decision-making.

Who is it for? AFM spans the entire S&P 500 and is primarily intended for institutional investors, Family Offices and High-Net-Worth Individuals, where sufficient capital allows broad diversification across the index and efficient execution.

AFM is equally well suited to long-term investors seeking to build and preserve wealth across generations — for example, education funding, property acquisition and retirement planning — where consistency and capital preservation are paramount. See history

Arrange a Consultation

All enquiries are treated with strict confidentiality.

Assets remain in your brokerage account. AFM has trading authority only and cannot withdraw cash, transfer securities or access the master account. A master/sub-account structure is recommended for additional protection.
AFM connects to your existing brokerage account and applies a systematic investment process. Investment decisions are generated by the AFM procedure without discretionary intervention by a human portfolio manager.
Yes. Since your assets remain in your own account, AFM can be discontinued at any time with a single click through the AFM Client Portal or by contacting the service provider.
AFM charges an annual service fee of 0.75% of assets under management. There are no performance fees or additional commissions charged by AFM. Larger portfolios may qualify for institutional pricing.
No. AFM follows a long-only investment strategy.
AFM originated as a scientific research project supervised by the University of Applied Sciences of Western Switzerland (HES-SO). It was conceived by Peter Seilern and developed with Leyun Xia. LX InfoTech Sàrl provides portfolio configuration and technical support.
Over the period analysed, AFM generated an average daily outperformance of 0.01%, with a standard deviation of 0.07%, indicating low variability in its daily excess returns.
A minimum investment of US$1 million is required to implement the strategy efficiently across the S&P 500 universe. Below this amount, transaction costs may have a disproportionate impact on performance.
AFM is a combination of curiosity and common sense. There is no catch.

Origins of AFM

Autonomous Fund Management (AFM) originated from a concept conceived by Peter Seilern, who sought a fundamentally different approach to investing in equity markets.

Early work, including Computer-Assisted Trading (CAT), demonstrated that investment decisions could be improved through data-driven, mathematical processes rather than human judgment.

Practical implementation, however, was not feasible at the time. Critical elements, such as reliable internet connectivity, cloud computing, real-time market data, instant trade execution, and sufficiently low transaction costs, were not yet available.

It was not until the early 2000s that these technological conditions began to emerge, and thanks to further development, the concept evolved into a workable framework.

Ten years ago, in collaboration with HES-SO Valais (University of Applied Sciences of Western Switzerland), the system was further refined and adapted for practical application.

This process culminated in the launch of AFM in its current form—a self-sustaining, data-driven investment procedure operating entirely without human intervention.

LX InfoTech Sàrl was subsequently established to support the deployment of AFM, providing dedicated services to investors while ensuring the system’s ongoing advancement.

Today, AFM is further enhanced through the integration of artificial intelligence while remaining firmly anchored to its founding principle: the complete absence of human judgment in investment decisions.

Portrait of Peter Seilern

Peter Seilern

Peter Seilern, now inactive, earned his Master's degree in Physics at the EPUL, the Federal Polytechnic School of Lausanne (EPFL). He gained experience as a research engineer at Litton Industries' Guidance and Control Systems Division in California before spending three years in New York as an associate at Dillon, Read & Co. Inc.

Upon his return to Switzerland, he pioneered the development of Computer-Assisted Trading (CAT), a system that enables investors to trade securities depending on performance metrics and other criteria.

Autonomous Fund Management (AFM), an extension of CAT, was first introduced in 2007 and provides investors with a data-driven approach to managing their assets. In early 2019, he collaborated with HES-SO Valais to launch the current version of AFM.

Portrait of Leyun Xia

Leyun Xia

Leyun Xia was born in Shanghai, where he studied French at university. At the age of 21, he moved to Switzerland to continue his studies and after a language stay allowing him to perfect his French, he joined the HES-SO Valais where he obtained a Bachelor’s Degree in computer science and a Master's in Business Administration.

He then worked for 10 years as a research scientist at the same university, participating in projects devoted to the fields of data mining and machine learning.

In 2017 he paired with Peter Seilern as part of a research project at HES, playing a key role in the development and testing of AFM, before successfully deploying the system into a live environment in mid-2019.

Leyun founded LX InfoTech Sàrl to continue developing AFM’s program in a fast-changing financial market. The company also provides an exclusive service for AFM account holders, taking responsibility for setting up accounts and their ongoing maintenance.
