Crisis test
A standard model called 2008 and 2022 once‑in‑centuries events. Prometheus had them in the plan.
We rebuilt both models on the eve of each crisis, using only the data that existed then, and asked one question: how rare would the next twelve months be for a classic 60/40 portfolio? The standard model fits a bell curve to the portfolio’s own past. Prometheus adds the shape of every crisis in 18 countries’ history.
