BIST Strategy Indices

The objective of leveraged indices is to reflect the return of a reference index (underlying index) by multiple of the leverage factor in the same direction. It is assumed that, leverage is obtained by borrowing money and investing more in underlying index. The borrowing costs of the leverage is supposed to be on daily repo interest rates. Thus, the index is calculated by deducting the borrowing cost (return on BIST-KYD Repo (Net) Index) from the return on underlying index.

The objective of short indices is to reflect the return of a reference index (underlying index) by multiple of the leverage factor in the opposite direction. It is assumed that, short position is obtained by borrowing equities in underlying index, selling them short, and investing the fund generated, in repo. Thus, the index is calculated by adding the return on lending (BIST-KYD Repo (Net) Index) to the return on underlying index.
