How it's computed

For every open-market buy (Form 4 code P, acquisition A) in the selected window, we take the closing price on the transaction date and 90 calendar days later, then compute the percentage change. The figures shown are the simple average and median of those per-buy returns.

  • Window follows the rest of the summary (all-history or last 3 months).
  • Only buys with a resolved price context are counted.
  • Includes both positive and negative outcomes; gains and losses net out at the per-buy level.
