Portfolio Stress Test

Explore how a fixed buy-and-hold allocation would have moved through four well-known market selloff windows. Weights must total 100%, and the result clearly identifies unavailable historical windows.

How this tool works

The model begins each available crisis window with a hypothetical $10,000 portfolio and carries the selected allocation without rebalancing. It uses Yahoo Finance adjusted close when available and does not include taxes, fees, slippage, or cash flows.

Does a historical stress test predict future losses?

No. Historical drawdowns describe selected past windows only. Future market structure, correlations, liquidity, and recovery paths can be different.
