In this capped weighted index method, single stocks are confined to a maximum weight of 33%, and the excess weight is distributed proportionately among the remaining index stocks.

AWFi = Adjusted Stock Market Value factor assigned on rebalancing date

Divisor = Index Market Value after rebalancing / Index Value before rebalancing

Single stocks are capped at 33% while the aggregate weight of the top three constituents is capped at 63%.
