Methodology

[APPROACH]

A systematic factor engine.

The strategy uses a single fundamental signal to systematically rank and select equities. The signal targets a persistent cross-sectional relationship — not momentum, not valuation, not sentiment. Holdings are held for extended periods, and the approach is designed to captures known factor premia through a disciplined, repeatable process.

> Performance varies across market regimes. Returns are primarily consistent with established factor exposures — not unexplained alpha.

[SIGNAL] tune

Fundamental Signal

A single accounting-based metric with persistent cross-sectional predictive power. Constructed from publicly available financial data. No look-ahead, no data-mining.

[UNIVERSE] filter_alt

Mid-Cap Universe

Diversified US equity universe in a targeted market-cap range. Sector and concentration constraints applied at the portfolio level.

[WEIGHT] balance

Simple Construction

No optimization overfit. Portfolio rules are simple, transparent, and resilient under conservative transaction cost assumptions.

[FACTOR_ATTRIBUTION]

pie_chart Factor Attribution

> Returns are primarily consistent with established factor exposures. No statistically significant alpha detected — the signal effectively harvests known premia simultaneously. Evaluated via multi-factor model (R² = 0.85).

> Portfolio construction characteristics naturally result in controlled sector exposure. Signal demonstrates persistent behavior across multiple holding horizons, supporting the current rebalance cadence with structural reasoning.

Research Process

[PRINCIPLE_1] science

Mechanism First

Every signal must have a stated economic mechanism. Cross-sectional patterns without return-side implications are measurement artifacts, not strategies.

[PRINCIPLE_2] lock

Lock Before Search

No factor research until a specific identified deficiency exists. "Increasing CAGR" is not a valid reason. Correct question: what risk does this reduce?

[PRINCIPLE_3] gpp_maybe

Pre-Specified Exits

Every strategy ships with yellow/red flags defined before deployment. No post-hoc rationalization. If breached, stop first — then investigate.

[DEFICIENCY_ANALYSIS]

Documented Regime Behavior

> Performance varies across market regimes, with documented periods of relative weakness. Rather than hiding weak periods, every regime where the strategy lags its own universe has been identified, quantified, and classified by evidentiary strength.

No further search until trigger condition met

"The measurement is real. The interpretation it suggested is wrong." — Candidate mechanisms were tested directly and falsified when they failed to improve robustness.

[CLOSED_BRANCHES]

> Multiple alternative specifications were evaluated and removed when they did not improve expected behavior. No factor is added to an existing strategy without a specific identified deficiency it solves.
