Borsa Istanbul: BIST Stock Indices Ground Rules Has Been Updated

According to BIST Stock Indices Ground Rules, the free float market value as of the end of the review period and the daily average traded values for the review period are used to determine the constituents of BIST 100, BIST 50, BIST 30 and BIST Dividend 25 indices at their periodic reviews.

For the purpose of minimizing the effects of extraordinary price movements on the indices in question, Borsa İstanbul Management, has decided to revise the BIST Stock Indices Ground Rules in order to use free float market value, which is calculated by multiplying the median of adjusted prices for the review period (last 6 month) by the number of shares and the free float ratio as of the end of the review period.
