What Is Index Rebalancing?
Rebalancing is the process of adjusting the components and weightings of an index based on updated data, such as market capitalization and trading activity. It ensures that the index remains aligned with its core criteria and objectives.
In the case of the Nasdaq 100, the goal is to represent the 100 largest non-financial Nasdaq-listed companies.
