Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

Capabilities

Tools 6

backtest_portfolio

Use this when the user describes a portfolio of US stocks and ETFs with weights (e.g. "60% VTI, 40% BND", "equal parts AAPL, MSFT, NVDA") and wants to know how it would have done or how risky it is: returns over YTD, 1 year and 5 years (rebalanced quarterly), max drawdown, volatility, Sharpe, beta vs SPY, dividend yield and the correlation between holdings, charted against SPY, with a link that opens it on Redstone to save. 2 to 20 holdings. Not for live brokerage accounts, trading or allocation advice.

Discovered
compare_securities

Use this when the user wants to compare 2 to 5 US stocks or ETFs side by side (e.g. "VOO vs QQQ", "SCHD or VYM?"): returns, drawdown, volatility, Sharpe, beta, dividend yield and how correlated they are, with an overlaid 1Y/5Y chart. End-of-day data for US large and mid caps, major foreign stocks and US ETFs. Not for intraday quotes or recommendations on what to buy.

Discovered
get_portfolio

Use this when the user asks about one public Redstone portfolio, usually a search_portfolios result: its holdings with each one's own figures, its returns over YTD, 1 year and 5 years, max drawdown, volatility, Sharpe, beta and dividend yield, charted against SPY. Not for a portfolio the user describes (use backtest_portfolio) or private portfolios.

Discovered
get_security_metrics

Use this when the user asks how a single US stock or ETF has performed or how risky it is: YTD, 1-year and 5-year annualized returns, max drawdown, volatility, Sharpe, Sortino, beta, alpha and dividend yield, with a 1Y/5Y chart. End-of-day data for US large and mid caps, major foreign stocks and US ETFs. Not for intraday quotes, news, earnings, fundamentals or price targets.

Discovered
screen_securities

Use this when the user wants a ranked list of US stocks or ETFs by a performance, risk or dividend yield metric, optionally within a sector or ETF category (e.g. "lowest volatility dividend ETFs", "highest yielding bond ETFs", "highest Sharpe tech stocks this year", "energy stocks with the smallest drawdown"). Covers about 2,900 US-listed stocks and about 1,200 US ETFs, end-of-day. Not for fundamentals (P/E, revenue), news or buy recommendations.

Discovered
search_portfolios

Use this when the user wants to see real portfolios to learn from or copy (e.g. "show me low-drawdown dividend portfolios", "portfolios that hold SCHD", "the best risk-adjusted portfolios on Redstone"): the public portfolios Redstone's users built and shared, and Redstone's model portfolios, with past-year returns, risk and yield. Describe the kind of portfolio with the figure filters where one fits; nameIncludes only matches names, so keep it for themes no figure captures, such as "AI". Up to 10 results. Not for the user's own brokerage account or for recommending a portfolio to buy.
