Intelligence

Portfolio stress tester

Compare your open paper holdings with historical broad-market drawdowns. Each result uses adjusted daily SPY closes and current provider marks.

Informational estimate, not a forecast

This model applies each historical SPY peak-to-trough move at beta one to supported U.S. equity and ADR notionals. It is not instrument-specific repricing. Cash, diversification, options, dividends, fees, taxes, borrow costs, margin, and liquidation effects are excluded. This is not investment advice.
