Portfolio risk and correlation

In this lesson

Measure total open risk and see how correlation changes the real risk of a portfolio.

Key takeaways

  • Portfolio heat = total risk of all open positions; many cap it at ~5–6%.
  • Highly correlated positions behave like one larger position.
  • Two-asset volatility: √(w₁²σ₁² + w₂²σ₂² + 2w₁w₂ρσ₁σ₂).
  • Correlations tend to rise in crises — diversification is weakest when you need it most.
