The objective of creating the passive index funds is to generate the market return. The term ‘market return’ is generally associated with the returns generated by the underlying index. As the name suggests, the fund manager invests passively in all the constituents of an underlying index in the exact proportion they represent in the index. He does not make any discretion in either selection of a stock or asset allocation. Simple rule for him is to ‘Follow the index’. Any changes that are made to the index will be applied by the fund manager to the index funds.
Investors can buy or sell the units of the index funds by approaching the asset management companies (AMCs) or its distributors. Buy or sell of these units is done based on the net asset value (NAV) of the index fund which is declared at the end of the day. As buy/ sell of index fund units takes place based on NAV calculated on end of day basis, investors are generally deprived of taking a benefit of intraday volatility of the index as this units are not available for trading on the stock exchange (can be bought and sold only through an AMC or its distributor).
