The Marvel index is up 16.03% over this period, -1.97% in the last 7 days against -3.54% over 30. It sits 12.34% below the period high (79 on Aug 21) and 16.16% above the period low (Oct 14).
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 223 most-traded cards in this basket; the recent window covers all 7,594 tracked cards. Not investment advice.
