Built from contract counts, not weights — a price move can't show up as a trade. Changes of equal size on the same stock are paired: a roll closes one expiry and opens the next, a synthetic (long call + written put at one strike) is stock exposure, not two bets. Negative = written.
Share of the $1.25B stock book with a call written against it, by value. Uncovered stock keeps all of its upside and pays no premium.
