Why average down (or up)?

Averaging down means buying more when the price falls — lowering your overall cost basis. It works only if your thesis still holds. Don't average down on broken stories — you'll just lose more capital.

Averaging up means buying more as the stock rises — your thesis is being validated. Some of the best long-term investors only add to their winners.

Formula

Avg Price = Σ (qty × price) / Σ qty

Note: Brokers may apply FIFO accounting for tax purposes (LTCG/STCG calculation), which can differ from your weighted average cost. This calc is for tracking purposes — verify your broker's methodology for tax filing.
