The AppliedComplexity Creed
01

Humans are complex adaptive systems.

02

The economy is a complex adaptive system composed of humans.

03

Markets are the economy's information processing mechanism.

04

Regimes are the economy's discrete behavioral states.

05

Transitions between regimes are probabilistic, not deterministic.

06

Historical regime behavior rhymes but doesn't repeat.

07

SHAP attribution reveals which forces drive the current regime.

08

Probabilistic characterization beats point prediction.

01What I'm Building

Detecting market regimes before the damage is done

MacroContext is a quantitative framework that identifies prevailing market regimes using macro and market stress indicators. By systematically reducing equity exposure during confirmed stress periods, the framework has historically produced nearly double the Sharpe ratio with 38% less volatility than buy-and-hold. The model is entering live validation in April 2026.
