Slabline™
Graded-card protection score
Slabline™The Disney index is up 35.38% over this period, -0.04% in the last 7 days against +35.68% over 30. It sits 0.05% below the period high (99 on Oct 28) and 35.38% above the period low (Oct 12).
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.
Value-weighted index, base 100 at the window start: the sum of the basket's observed values against the prior day's, chained daily, each card's move capped so one outlier can't dominate. Values come from real comparable sales resolved on Slabline card pages. The window deepens automatically as history accumulates. Long-run history reflects the 3 most-traded cards in this basket; the recent window covers all 27 tracked cards. Not investment advice.
