Why Demeter?

Precision, Discipline, and Daily Advantage

At Demeter Tactical Investments, we believe that successful investing is built on precision—the disciplined pursuit of opportunity on with a one-day horizon.

Our philosophy is simple: long-term results are the sum of short-term decisions. We apply a systematic, price-based process designed to determine when risk should be taken—and when it should not.

Our strategy operates with a one-day horizon, dynamically allocating between the S&P 500, NASDAQ 100, & MSCI EAFE Indexes and U.S. Treasuries at the close of each trading day. 

Rooted in Eugene Fama’s Nobel Prize-winning research on market efficiency, our proprietary model evaluates price—the purest reflection of market information. When conditions favor equities, we seek exposure. When they do not, we shift defensively to Treasuries. The result is a process that aims to compound advantage daily, not occasionally.

Built on Research

Inspired by Professor Fama’s insight that price embodies all available market intelligence, Founder & Chief Investment Officer Jeffrey A. Sexton deployed Demeter’s proprietary algorithm in 2012.

Over more than a decade, this model has proven accurate and resilient during rigorous empirical testing and live trading experience. The result is a repeatable, evidence-based framework that captures the efficiency of markets while exploiting daily inefficiencies through disciplined execution. 

Institutional Governance
& Global Infrastructure

Demeter operates as a fund manager regulated by the Abu Dhabi Global Market Financial Services Regulatory Authority (FSRA).

Our service providers include Ascent Global Fund Services (fund administrator), independent auditors including KPMG & Deloitte, and institutional banking and brokerage partners including Pershing-BNY, Northern Trust, & Bank of Montreal — ensuring transparency, segregation of duties, and robust operational control across every jurisdiction. 

A Team of Specialists

Demeter’s leadership combines deep expertise across investment management, quantitative research, operations, law, and technology.

From Jeffrey Sexton’s macroeconomic insight and portfolio management experience, to P.J. Steele’s highly scalable and hardened infrastructure, to James Chen’s data-science leadership, and John Hensel’s regional expertise in the Middle East, Demeter’s team embodies both intellectual diversity and institutional discipline. 

Each team member shares a unified commitment: applying evidence, structure, and accountability to every aspect of fund management. 

Risk as a Discipline
