The Japanese Pokémon index is up 39.93% over this period, -5.78% in the last 7 days against -18.00% over 30. It sits 20.43% below the period high (102 on Sep 13) and 57.75% 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.

Values come from real comparable sales resolved on Slabline card pages. The window deepens automatically as history accumulates. Long-run history reflects the 6,492 most-traded cards in this basket; the recent window covers all 27,676 tracked cards. Not investment advice.
