What is a portfolio stress test?

A portfolio stress test simulates how your investment holdings would perform during historical market crashes like 2008 GFC or 2020 COVID. It estimates your potential losses based on how each sector performed during those crises.

How is the portfolio health score calculated?

The health score (0–100) combines four factors: diversification (number of stocks and sectors), concentration risk (Herfindahl index), crash resilience (average simulated drawdown), and balance between defensive and growth sectors.
