• Periodic changes on stocks within ISE 30, ISE 50, ISE 100 and ISE 10 Bank Indices are conducted according to the following principles, based on the study carried out for the next index period using the appraisal period data:

In order for a stock which is not a constituent to be included in that index, it must rise to a specific upper rank or above in the final ranking and in order for a constituent stock to be excluded from that index, it must fall under a specific lower rank in the final ranking.

Specific upper and lower ranks are; 25th and 35th for ISE 30 Index, 45th and 55th for ISE 50 Index, 90th and 110th for ISE 100 Index and 8th and 12th for ISE 10 Bank Index.

In the final ranking;

Stocks which ascend to the specific upper rank or higher and are not covered by the index are included in the index.

Stocks which descend down below the specific lower rank and are covered by the index are excluded from the index.

If the number of stocks ascending to the specific upper rank or higher is higher than the number of stocks which descend down below the specific lower rank, then starting from the stock which is positioned in the specific lower rank, the required number of stocks in the upper ranks are excluded from the index until the numbers of stocks included-excluded are equal.

If the number of stocks descending down below the specific lower rank is higher than the number of stocks ascending to the specific upper rank or higher, then starting from the stock which is positioned one place below the specific upper rank, the required number of stocks in the lower ranks are included the index until the numbers of stocks included-excluded are equal.

• Reserve Stocks: 2 stocks for ISE 30, 3 stocks for ISE 50, 5 stocks for ISE 100, 2 stocks for ISE 10 Bank indices and 5 stocks for ISE Dividend 25  are selected as substitutes for any changes likely to occur within the period and this Reserve List is announced concurrently with the periodic changes.
