Written in public.

Method
How we operate
-
Research before size.
Regime detection, signal construction, backtest discipline. If a study cannot survive being written down, it does not deserve capital.
-
Our book. Our risk.
We are not a hedge fund. We do not manage outside capital. The journal is free; membership is optional.
-
Systems improve in public.
Long-form notes, published as the work happens. Writing forces precision. Precision improves the models.
About
The firm
A small quant desk.
Written down in public.
One desk, a model registry, and a bias toward writing things down. We run quantitative strategies in US equities, with research oriented around regime detection and risk-conditioned position sizing.
The work is the point. The publishing is a forcing function.
