The Ted Williams index is up 5.66% over this period, -6.26% in the last 7 days against +5.70% over 30. It sits 9.26% below the period high (111 on Oct 1) and 5.66% above the period low (Sep 12).
Gains for the period are intact but the latest week is soft — a pause rather than a reversal unless the low gives way.

Values come from real comparable sales resolved on Slabline card pages. The window deepens automatically as history accumulates. Long-run history reflects the 64 most-traded cards in this basket; the recent window covers all 245 tracked cards. Not investment advice.
