Redstone

Redstone is a portfolio tracker that lines up return, drawdown and Sharpe for a mix of stocks and ETFs, for people deciding which public portfolio to copy.

One screen for the mix, not a place to place a trade

You build a portfolio, look at other people's public ones, and clone one to change it. The about page says the site covers about 2,500 US stocks and 940 ETFs. The homepage screen is worded as 3,400 or more stocks and ETFs, filtered by return, risk and yield. Each ticker gets a score out of 100 against its peers. A comparison of two tickers or portfolios is on the homepage, and that page says it is free and needs no account. About goes further: every ticker page, comparison and model portfolio is free to view without an account. Nothing on these pages is an order ticket. About says the site is informational and educational, not investment advice, and that past performance does not predict future results.

The image on this page is the homepage demo, captured while it was showing Redstone's own All Weather (Dalio-style) model, not a portfolio built here. The panel said that model returned +4.58% over the past year and +2.77% a year over five years, that its worst drop in that year was -4.84%, that the drop was smaller than 9% of portfolios on Redstone, and that its Sharpe ratio of 0.04 beats 12% of them. It listed a 3.00% yield. The holdings on screen were VTI, TLT, IEF, GLD and DBC. The same demo, a moment earlier, was on their MAG7 model: +9.66% over the past year, +22.63% a year over five years, a max drawdown of -18.25%, and a Sharpe ratio of 0.33. A separate block on the page, a one-stock Tesla example, says its figures run to the October 26, 2026 close. These are the site's numbers.

The demo is signed in as Mihai, with a Pro badge. The about page does not say who Mihai is, and it does not name a person or company behind the product. The footer copyright reads Redstone Markets, and the contact address is [email protected].

Where the figures come from

• Prices, dividends and splits come from Massive, formerly Polygon.io, updated every trading day after the US market closes.
• Returns include reinvested dividends. Risk metrics use the past year of daily closes. The Sharpe ratio uses a 4.5% risk-free rate. Beta and alpha are measured against SPY.
• A portfolio is put back to its target weights at the start of every quarter.

Free to look, paid to keep more private mixes

• Starter is $0 a month: 5 portfolios, 10 assets in each, 3 optimizations a day, 25 watchlist items, the charts and risk metrics, the screeners, and a daily market update.
• Plus is $15 a month: 25 portfolios, 25 assets in each, 50 optimizations a day, 50 watchlist items, and private portfolios. The plan says you can cancel anytime.
• Pro is $50 a month: unlimited portfolios, assets and optimizations, 75 watchlist items, priority support, and early access to new features.

A read-only feed for a chat assistant

About also documents a free connector at redstonemarkets.com/api/mcp. It needs no account and no API key. An assistant can ask for one ticker's return, drawdown, volatility, Sharpe, beta and dividend yield, compare two to five tickers, backtest a mix you describe against SPY, screen by a metric, or open a shared portfolio. The page's example is a backtest of 60% VTI and 40% BND. The figures are the ones already on the site.
