One purchase is counted at each month's closing price; trading fees and slippage are not included.
Calculated in US dollars; the Turkish lira equivalent is not shown because historical USD/TRY rates are not available. The past price is the close nearest to the target date (the series is mostly monthly); the date used is shown in the table. Past returns are not a guide to future returns, and this page is not investment advice.
