The index includes the same companies as its parent index, but weighted equally.
"Nifty 50 equal weight index is a smart yet simple index strategy - which allocates equal weight to all companies in the index, instead of considering their economies or market capitalisation as the sole criteria for weight allocation. This gives fund managers an alternative index strategy to explore," IISL CEO Mukesh Agarwal said in a statement.
The base date for the index is November 3, 1995 and base value is 1,000. The index composition will be reconstituted semi-annually along with Nifty 50.
The weights may, however, drift between rebalancing due to movement in stock price.
