[ about ]
Redstone lets users track portfolio performance and analyze risk using metrics such as the Sharpe and Sortino ratios, with 20+ metrics in total.
The site states it tracks 3,400+ securities with 5Y+ of historical data and daily data refresh, and offers a screener to filter stocks and ETFs by return, risk and yield. Users can build portfolios, share them with the community, and compare any two tickers or portfolios side by side.
Free comparison pages for popular ETFs (e.g., VTI vs VOO) are described as free and requiring no account. Plans are Starter ($0/month placeholder), Plus ($15/month placeholder) and Pro ($50/month placeholder), with more portfolios, optimizations and watchlist items at higher tiers.
