Calculation Methodology

The index value is calculated using a float-adjusted market capitalization weighting methodology. Here’s a simplified breakdown:

  2. Aggregate Market Cap: Sum the market caps of all 500 companies.
  3. Index Divisor: Divide the aggregate market cap by an index divisor, which is adjusted over time to account for corporate actions like stock splits and mergers.
