On the Physics of Expected Asset Returns

papers.ssrn.com2026-04-20Paper
Executive summary

A new asset pricing study introduces a dual-state model, splitting expected returns into long-term and short-term components. It finds mean reversion is structurally required, with expectational dispersion decaying exponentially. The Asset Opportunity Space (AOS) sets a theoretical profit limit from market inefficiencies, similar to information theory. The Relativity Theorem shows investors see different opportunities based on their baselines. Analysis of U.S. equities, gold, and Bitcoin confirms these findings, noting Bitcoin’s declining profit potential.

What it examines

This paper introduces a new way to understand asset returns by separating long-term growth from short-term market changes. Using a physics-inspired model, it explains how expected returns can be broken into two parts, without relying on traditional finance assumptions, to better capture market behavior.

What it concludes

The results show that market opportunities and risks depend on each observer’s viewpoint, and that mean reversion is a built-in market feature. This framework can help investors, regulators, and researchers better measure market efficiency and identify trading opportunities. Future work could explore more assets and refine these models.
