Buys on the first stored trading day of each month; latest close 30 Oct 2026.

How it works

This replays buys on the price index itself, the closest picture of an index fund before its expense ratio and tracking difference. Index price levels exclude dividends, so a total return fund would have done a little better. Our NSE index history starts on 24 Sep 2025.

Formula

Units = amount / index close on the first trading day of each month; value = units x latest close
