Redstone

Redstone is a portfolio analytics and optimization platform for people who want to manage their investments with data instead of intuition. It combines portfolio tracking, a stock and ETF screener, peer ranking, and side-by-side comparison in a single web dashboard, then layers on the same risk metrics that quantitative analysts and hedge funds use. The platform covers more than 3,400 securities with five or more years of historical data refreshed daily, and it lets investors build portfolios, share them publicly, and clone portfolios created by other users.

The core problem Redstone addresses is fragmentation. Investors who want a serious view of return and risk usually stitch together a brokerage view, a spreadsheet, and a separate charting tool. Redstone puts performance, drawdown, volatility, alpha, beta, and dividend yield on one screen, then adds portfolio optimization so an allocation can be tested rather than guessed.

What Makes Redstone Stand Out

• Institutional-grade risk metrics: Every portfolio and ticker is scored on Sharpe, Sortino, Omega, Calmar, and Martin ratios alongside alpha, beta, maximum drawdown, volatility, and current drawdown, so risk is measured rather than assumed.
• Screener plus percentile ranking: Filter 3,400+ stocks and ETFs by return, risk, and yield, and see each ticker ranked out of 100 against its peers on one-year return, five-year return, Sharpe ratio, drawdown, volatility, and dividend yield.
• Side-by-side comparison: Any two tickers or portfolios can be compared on returns, drawdowns, and risk in a single view, including popular pairings such as VTI vs VOO or SPY vs QQQ, with no account required.
• Community portfolios: Users publish portfolios, browse other investors' allocations, filter for a specific risk tolerance, clone a portfolio as a starting point, and share their own with a link.
• Usable free tier: The Starter plan costs nothing and still includes every chart and risk metric, the stock, ETF, and portfolio screeners, five portfolios, and daily market updates.

Who Should Use Redstone

• Individual investors managing their own money: They get portfolio tracking, drawdown monitoring, and dividend yield data in one place instead of reconciling a brokerage page with a spreadsheet.
• Quantitative analysts and finance students: The metric set mirrors what is taught in portfolio theory and used in professional risk reporting, which makes it practical for coursework, research, and quick sanity checks on allocation ideas.
• ETF-focused and dividend investors: Preset comparisons, screener filters, and yield rankings help identify low-correlation or high-Sharpe funds without building a model from scratch.
