How Weighted Average Works

(Shares₁×Price₁ + Shares₂×Price₂) ÷ (Shares₁ + Shares₂). Extend to more lots similarly – sum all costs divided by total shares.

When Averaging Down Helps
  • Conviction unchanged & long‑term thesis intact.
  • Company fundamentals improving vs price action.
  • Position size remains within risk limits.
Common Pitfalls
  • Averaging into declining fundamentals.
  • Ignoring portfolio concentration risk.
  • Chasing breakeven emotionally vs re‑evaluating thesis.
