What is an Index Fund?

Index funds are mutual fund schemes that track a stock market index, for example, the Nifty 50. In other words, an index fund invests in stocks that constitute a particular market index. Also, the weightage of the stocks is identical to the proportion of each stock that is a part of the index. 

In case there’s a change in the proportion of any stock, fund managers make changes to ensure that the weightage of the portfolio constituents matches that of a particular index that it follows. Nifty 50 Index Fund is one such example of this seemingly popular investment instrument.

This, in turn, results in a lower expense ratio. As per recent regulations of the Securities and Exchange Board of India, fund houses can levy a maximum expense ratio of 1% on this fund type. Hence, the investment cost remains low, helping individuals to increase their earnings.

The SIP route enables them to allocate a fixed sum to an index fund scheme at regular intervals (monthly, quarterly, etc.).  One can start investing in Nifty index funds with an amount as low as Rs. 500 via a SIP. 
  • No bias in investing: In the case of index funds, fund managers follow an automated investment strategy. Precisely, fund managers have a defined mandate regarding which stocks to buy or sell and in what proportion. As a result, there’s no room for human bias when making investment decisions.
