Changes in Index Rebalancing Dynamics
The landscape of index rebalancing has evolved significantly, particularly with the role of hedge funds that employ pre-positioning strategies ahead of index changes. There have been notable instances where hedge funds lost substantial amounts betting on stocks being added to or removed from major indices. For instance, in 2022, hedge funds faced losses during the Russell index’s annual revision, as the anticipated stocks did not perform as expected. This shift highlights the growing complexity in index rebalancing, with hedge funds now seen as necessary participants in these large-scale market movements rather than obstacles.
