Governing question
When does a model become a decision?
Markets punish false precision. Useful analysis distinguishes measurable risk from structural uncertainty, then connects a thesis to position, timing, liquidity, and an explicit condition for revision.

Models under pressure
A documented economics paper and SEC-recorded portfolio-management role place formal analysis inside markets, where timing, liquidity, incentives, and revision affect the decision.
A useful model does not remove uncertainty. It makes assumptions visible, locates exposure, and defines what evidence should change the position.
The role is historical. No fund performance, later tenure, or firm assets-under-management figure is claimed.
What must a model do when actors can adapt to it?
