Index
The BIST 100 is a price index and contains the 100 largest Turkish stocks weighted by market capitalization.[1] The index level is determined exclusively on the basis of share prices. Dividend payments are not included in the calculation of the index. The BIST 100 has been calculated since January 1, 1986. The index base was initially 100 points. With effect from December 27, 1996, the index was divided by 100, setting the 1986 base value at 1 point.[1] With effect from July 27, 2020, the index was divided by 100 again, setting the base value from 1986 at 0.01 point. The index is calculated in Turkish lira, which has been very inflationary in the past.[2]
