Portfolio Risk Rank

Risk Rank helps you build smarter investment portfolios using Modern Portfolio Theory (MPT) — the same mathematical framework used by professional fund managers.

* Simply add the stocks or ETFs you're interested in, choose your optimization settings, and Risk Rank calculates the efficient frontier: the set of portfolios that maximize return for a given level of risk. An interactive slider lets you explore the full range of risk/return trade-offs and find the allocation that matches your investment style.

* What Risk Rank does:
- Fetches real historical price data for any stock, ETF, or mutual fund
- Computes the efficient frontier using projected gradient optimization
- Shows portfolio weights, expected return, and risk for each point on the frontier
- Displays a pie chart, weights heatmap, covariance matrix, and component returns chart
- Lets you select your preferred risk tolerance interactively

* Free tier includes:
- Up to 4 securities
- Up to 10 optimization steps
- Up to 6 months of historical data

* Pro upgrade unlocks:
