Real history, not synthetic

Every scenario is a real market period — not a Monte Carlo simulation.

2008. 2020. The 1970s stagflation. The dot-com unwind. Replayed on your actual holdings, with the actual sector and factor exposures you have today.

Transparent assumptions

We show our work. Every number you see has a source line under it.

No black-box scoring, no proprietary risk index. If a holding's data was incomplete, we say so. If a scenario is approximated, we link to how.

How we calculate

Calm by design

No price-tracker urgency. No portfolio-influencer noise.

Built for investors who already have a plan and want to know where it breaks — not investors looking for the next ticker to buy.
