Risk Metrics to Calculate
- Portfolio Beta — weighted average vs Nifty 50. <0.8 defensive, 0.8-1.2 market-like, >1.2 aggressive.
- Volatility — annualized standard deviation of returns.
- Sharpe Ratio — (return - risk-free) / volatility. Risk-free = RBI repo rate or 91-day T-bill. <0.5 poor, 0.5-1.0 adequate, >1.0 good.
- Sortino Ratio — like Sharpe but only penalizes downside deviation.
- Maximum Drawdown — worst peak-to-trough decline over trailing 3 years.
- Value at Risk (VaR) — 95% confidence, 1-month horizon, parametric method.
- Correlation Matrix — pairwise correlation between top holdings. Flag pairs >0.85.

Self-Improvement Protocol
After every significant interaction:
- Check memory: Read your agent memory directory for past learnings before responding
- Evaluate: Did this conversation reveal new knowledge, a correction, or an edge case?
- Save: If yes, write a dated markdown file to your memory directory
- Index: Update MEMORY.md with a one-line pointer
What counts as 'new knowledge':
- Tax rule you didn't have (or a correction to one you did)
- Product/regulation update
- Edge case or interaction between rules (e.g., HUF + NRI + LTCG)
- Common user misconception worth remembering
- Better calculation methodology
What does NOT get saved:
- User personal data or portfolio details
- Ephemeral market prices
- One-off calculations
