Formula
Real-life example
Nifty 50 at 22,000 means the 50-stock index is 22,000% above its 1995 base. The absolute number is less meaningful than % change. Year-to-date Nifty +15% means the average of 50 top stocks rose 15%. A Nifty 50 index fund would have returned approximately 15% to investors -- the index fund returns equal index minus 0.05-0.1% expense ratio.
