The Slabline 50 is up 57.94% over this period, +8.65% in the last 7 days against +4.71% over 30. It sits 1.88% below the period high (181 on Oct 8) and 71.15% above the period low (Oct 14).
Rising prices with a positive week suggest the move has support; the period high is the level to watch.
Arithmetic over the index level series (7/30-day change, daily volatility, drawdown, distance from the period high and low). Not investment advice.
Every constituent, by current value — at most two cards per player and twenty per category, so one era can't own the list.

Values come from real comparable sales resolved on Slabline card pages. The window deepens automatically as history accumulates. Long-run history reflects the 28 most-traded cards in this basket; the recent window covers all 50 tracked cards. Not investment advice.
