Overview

The Baseball index is up 7.42% over this period, -1.32% in the last 7 days against -7.06% over 30. It sits 7.58% below the period high (97 on Sep 13) and 10.27% above the period low (Nov 6).

Key insights
  1. 1Both the 7-day (-1.32%) and 30-day (-7.06%) moves are negative — sellers have had the upper hand.
  2. 2Day-to-day volatility is very low at 0.23% a day, though the deepest pullback in the window was -7.6%.
  3. 33 consecutive down days — the longest run in view; the sharpest day was -1.13% on Sep 22.
Outlook

Gains for the period are intact but the latest week is soft — a pause rather than a reversal unless the low gives way.

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 23,455 most-traded cards in this basket; the recent window covers all 240,888 tracked cards. Not investment advice.
