TOKYO -- Nikkei said on Wednesday that it will introduce new rules for the Nikkei Stock Average, or Nikkei 225, in October based on the results of public consultations that took place between May 10 and June 12.
The main goal of the change is to reduce impact on the Nikkei 225 of adding new constituent stocks with relatively low trading values. Based on the consultations, Nikkei decided to add such stocks into Nikkei 225 in two phases, applying half the weighting each time.
