Analyse portfolio metrics with Claude and ToolRouter. Sharpe ratio, drawdown, and risk-adjusted return analysis.

Claude calculates portfolio metrics and interprets them within your investment context. It explains whether a Sharpe ratio is strong or weak for your strategy type, identifies which periods drove maximum drawdown, and compares performance against a benchmark — delivering a complete risk-adjusted performance review rather than just the numbers.

  1. Provide your portfolio return series (monthly or daily)
  2. Ask Claude: "Calculate the Sharpe ratio, maximum drawdown, and annualised volatility for this return series"
  3. Claude returns the metrics with interpretation
  4. Ask: "How does this compare to a 60/40 portfolio over the same period?"

Example Prompt

Try this with Claude using the Financial Calculator tool
Here are my monthly portfolio returns for the past 24 months: [returns]. Calculate the annualised return, Sharpe ratio (risk-free rate 5%), maximum drawdown, Sortino ratio, and Calmar ratio. Interpret whether this is a strong risk-adjusted performance.

Tips

  • Provide benchmark returns alongside portfolio returns to get relative metrics like tracking error and information ratio
  • Ask Claude to identify the specific months that contributed most to maximum drawdown
  • Request the rolling 12-month Sharpe ratio to understand whether risk-adjusted performance is improving or deteriorating
