StockRisker is a risk-first portfolio optimizer that focuses on structure, not stock picking. Instead of labeling portfolios as “low” or “high” risk, StockRisker shows how risk directly affects allocation limits, sector exposure, and diversification. Adjust risk levels and see live metrics like volatility, Sharpe ratio, and allocations update instantly. No accounts, no hype — just transparent, constraint-based portfolio design that runs entirely in your browser.
