How to Invest in Index Funds in India (Nifty & Sensex)

90% of mutual funds follow an active investing style.

Under active investing – the fund manager does extensive research to find stocks that will beat the market returns.

Remaining 10% are – Index funds.

Index funds follow a completely different – “Passive investment” style.

Index funds copy the movement of a particular index. The underlying index can be Nifty 50, Sensex 30, Nifty 100 or Nifty Next 50.

The index fund’s portfolio consists of the same stocks that are included in the underlying index, in the exact same proportion.

For example, below is the weight of the top 10 companies in Nifty 50.

NSE top shares by weightage

Index funds put all of the money in the same stocks that the index tracks. The amount of money invested in each stock is also in the same proportion as the index.

You can see that the ICICI Prudential Nifty Index Fund portfolio has shares investment in the same proportion (weights) as Nifty 50.

Nifty or Sensex is the common benchmark that most index fund follows.

A few other popular indexes are

  • Nifty Bank index
  • Nifty Midcap 
  • Nifty 100
  • Nifty Smallcap
  • Nifty Next 50

Will Index Fund Suit Your Investment Style

If you want to invest in equities but do not want to expose yourself to the risks associated with wrong selection of an individual stock then you can invest in Nifty or Sensex index fund.

Index funds minimise portfolio risk by investing in multiple stocks across different sectors.

The best part is that your portfolio is protected from the underperformance of any single stock because some other stocks in the index will be performing well. This way, you can expect a more stable return on your investment if the overall market is going up.

And that’s not all! Unlike actively managed funds, index funds don’t come with the added risk of the wrong selection of stocks by the fund managers.

If you’re looking for high risk high return funds then you may research equity funds that may perform better than the overall market.

Drawbacks of Investing in Index Funds

#1.  Risk of Tracking Error

Tracking Error arises due to minor differences in the composition of the index fund. Tracking errors can range from 0.03% to 0.16%.

Index share weight changes and corporate actions like bonus share issues cause tracking errors. Tracking error results in a slightly different return when compared to that of the benchmark index.

#2. Index Fund Doesn’t Offer Flexibility to the Fund Manager

An index fund has to be fully invested at all points in time. Even in extreme market upsides & downsides. 

The index fund manager has no flexibility to hold cash in a bearish market or increase allocation in high beta stocks in a bull market.

#3. Index Funds are Likely to Underperform

India has a developing stock market. This gives an opportunity to find undervalued stock. Active mutual funds invests in such undervalued stocks to generate higher returns by taking additional risks. 

In comparison to that – index funds simply invest in the underlying benchmark. The returns generated is similar to the indices.  

Investors looking for high-risk high return investments should avoid index funds.

Tax Implications of Investing in an Index Fund

Index funds are subject to capital gains tax when you sell your units.

Short-term capital gains (less than 12 months holding) are taxed according to the normal slab rate.

Whereas long-term capital gains (more than 12 months of holding) is taxed at the rate of 10% for capital gains over Rs. 1 Lac.
