Slabline™
Graded-card protection score
Slabline™The Bill Russell index is up 14.29% over this period, -7.62% in the last 7 days against +14.29% over 30. It sits 9.00% below the period high (93 on Oct 11) and 14.29% above the period low (Sep 14).
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 30 most-traded cards in this basket; the recent window covers all 94 tracked cards. Not investment advice.
