Redstone is a browser-based portfolio analytics workspace built for self-directed investors, students and quantitative analysts. Users assemble allocations from a tracked universe of 3,400+ stocks and ETFs, then score them against institutional-style risk statistics — Sharpe, Sortino, Omega, Calmar, Martin, alpha and beta — alongside return, drawdown and dividend-yield tables.
Starter is free and covers five portfolios, ten assets each and three optimizations per day. Plus runs $15/month for 25 portfolios, private visibility and 50 daily optimizations; Pro at $50/month removes portfolio, asset and optimization limits and adds priority support. All tiers include the full metric set and screener access.
The product is analytics-only — it does not execute trades or link brokerage accounts, so holdings are entered manually. Coverage centers on US-listed equities and ETFs; the site states no options, futures or non-US exchange support.
