Earlier index methodology and rebalancing updates around April 23, energy-transition collaboration news on April 21, and CARFAX used-vehicle data releases saw muted moves between roughly -1.13% and +0.44%. Today’s index change notice fits this pattern of limited price impact from operational index announcements.
