Value concentrates hard: across 191 measured Pokémon sets, the single top card typically holds about 16% of a set's total card value.

New Pokémon sets have typically settled somewhere between roughly 17% and 48% below their release-week price (a wider spread than other games), with most of that easing done within roughly 15 weeks (measured across 19 recent releases).

Over the first 30 weeks after release, that easing runs about 28% deeper than the market's own drift.

Across 71,958 measured breakaway moves in our archive, upward moves outnumber drops about 1.5 to 1.
