The Vintage Pokémon index is up 58.16% over this period, -9.91% in the last 7 days against -22.02% over 30. It sits 24.11% below the period high (201 on Sep 13) and 58.32% above the period low (Oct 24).
Gains for the period are intact but the latest week is soft — a pause rather than a reversal unless the low gives way.
Arithmetic over the index level series (7/30-day change, daily volatility, drawdown, distance from the period high and low). Not investment advice.

Long-run history reflects the 4,484 most-traded cards in this basket; the recent window covers all 9,557 tracked cards. Not investment advice.
