## Tools (4)

- `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, Sharpe, beta vs SPY and the correlation between holdings, charted against SPY. 2 to 20 holdings. Not for live brokerage accounts, trading or allocation advice.
- `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, Sharpe, beta 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.
- `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, Sharpe, Sortino, beta and alpha, 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.
- `screen_securities`: Use this when the user wants a ranked list of US stocks or ETFs by a performance or risk metric, optionally within a sector or ETF category (e.g. "lowest volatility dividend ETFs", "highest Sharpe tech stocks this year", "energy stocks with the smallest drawdown"). Covers about 1,100 US-listed stocks and about 480 US ETFs, end-of-day. Not for fundamentals (P/E, revenue), news or buy recommendations.
