The Yu-Gi-Oh index is up 37.58% over this period, -2.38% in the last 7 days against -2.23% over 30. It sits 15.61% below the period high (115 on Jun 5) and 38.24% above the period low (Oct 21).
Gains for the period are intact but the latest week is soft — a pause rather than a reversal unless the low gives way.
