The Pikachu index is up 11.95% over this period, -4.32% in the last 7 days against +17.13% over 30. It sits 8.96% below the period high (546 on Aug 22) and 13.89% above the period low (Aug 9).
Gains for the period are intact but the latest week is soft — a pause rather than a reversal unless the low gives way.
