The Number Your Advisor Has Never Shown You

The flagship Eddy Wealth article explains why performance is not the right unit for retirees, why spouse exposure belongs in every serious retirement conversation, and how the Margaret Number™ makes that gap visible in years.

The research archive houses notes, transcripts, and supporting editorial pieces built around the same core question: how long?

Academic foundations

Peer-validated building blocks. Proprietary diagnostic.

The RRH™ and SRH™ frameworks are built on Grinold-Kahn alpha decomposition and Hoffstein-Sibears recovery horizon research, extended to decumulation by Art Johnson and independently validated by academic reviewers, mathematicians, and leading quantitative researchers.

01

Foundation

Grinold-Kahn alpha decomposition

The core academic building blocks remain visible without turning the public site into a formula sheet.

02

Extension

Hoffstein-Sibears recovery horizon research

The logic is extended into retirement decumulation, where time matters more than benchmark theatre.

03

Boundary

Diagnostic shared. Recipe protected.

Eddy Wealth can explain what the instrument measures without revealing the proprietary implementation.
