A Nifty 500 index fund is a mutual fund that puts money into the 500 biggest companies on the National Stock Exchange in the same mix as the Nifty 500 index. The Nifty 500 index covers medium and small companies so the Nifty 500 index fund gives you exposure to the whole market not only the biggest companies.

The trade‑off is that the Nifty 500 index fund goes up and down with the market. The mid and small companies in the Nifty 500 index also make the Nifty 500 index fund more volatile than a fund that holds large companies.

Who may consider a Nifty 500 index fund
A 500 index fund suits investors who have a long horizon, usually five to seven years or more. They want market exposure at a low cost and can tolerate falls of 30% or more in a bad market. A 500 index fund is less suited to money that is needed in a few years and to investors who want protection in a falling market because the Nifty 500 index fund follows the index no matter what the market does.
What investors should take from this
