How To Select The Best Index Fund For Your Portfolio? (2024)

Globally passive investing is becoming increasingly popular. In India, too, it has gathered steam. At present, there are over 70 index funds in the country.

For the uninitiated, these passive funds mirror an index—they invest in the same stocks as the index they are tracking and in the same proportion.

Passive funds are generally of two kinds—index funds and exchange-traded funds (ETFs). For investing in ETFs, you need a demat account as they can be bought and sold on the stock exchange, just like stocks.

On the other hand, in index funds, you can buy the units from the fund house like any other mutual fund.

If you don’t have a Demat account and are planning to invest in passive funds, index funds are the way to go. However, selecting the one right can be challenging. This blog will explain how you can choose an index fund that’s right for you.

Financial Planning With Index Funds

With the number of index schemes on the rise, you can find an alternative to all major active mutual fund categories. There are large-cap, mid-cap and small-cap index funds. You can even find a replacement for multi-cap and Flexi Cap categories. If you want to take exposure to sectors, some ETFs track sectoral indices like Information Technology, Healthcare, Auto, etc.

With so much variety available, it’s easy to rely on index funds for your entire financial planning.

Let’s look at each category of equity funds and their index fund alternatives.

Large Cap Index Investment Options

In the large-cap space, passive funds track six indices. These include three from NSE and an equal number from BSE.

NIFTY 100Axis NIFTY 100 Index
S&P BSE 100SBI ETF BSE 100

Performance Of Large Cap Indices

To understand how each index has performed, we looked at the rolling returns for 15 years. Rolling returns will tell you what could have been your returns if you had entered for a three- or a five-year period in the past decade and a half.

Data shows the NIFTY NEXT 50 index has offered the highest returns. However, it can be volatile in the short term (three years) – it could fall more than other indices.

Should you then invest in NIFTY NEXT 50 when choosing a large-cap index fund? A better option will be to split your investments in NIFTY 50 and NIFTY NEXT 50. If you do this, you don’t need to invest in NIFTY 100 or SENSEX 100 indices, as they have the same stocks as the other two indices.

Broader Market Index Funds

Investors looking at a broader and more diversified index to invest in have three options. These funds are an alternative to actively managed multi-cap funds.

Performance Of Broader Indices

In the long term, NIFTY 500 has offered better returns than the other two indices. However, the Nifty LargeMidcap 250 Index can be slightly less volatile than the other two due to the absence of small-cap stocks.

Mid Cap Investment Options

Mid-cap indices typically have 150 companies. However, some funds only look at the top 50 mid-cap companies. That gives investors three options.

Performance Of Mid Cap Indices

Without a doubt, Nifty Midcap 150 is one of the best indices among the mid-cap. It is less volatile than others while generating better returns. It is valid for the short as well as the long term.

Small Cap Index Investment Options

In small-cap indices, too, investors can choose from two different options. One index covers all 250 small-cap companies. The other focuses on the top 50 small-cap stocks.

However, small caps are best-suited for tactical bets unless the investor is genuinely looking at a long-term horizon. Tactical bets mean investors need to enter small-cap stocks at attractive valuations and exit when they are high. But it’s easier said than done.

If you still decide to invest in a small-cap index, limit your allocation to 20-25% of the equity portfolio at max.

How To Choose the Right Index Fund For You?

If you are looking at index investing, it’s better to go with a broader index than select a few stocks in any segment. Therefore, avoid indices like Small Cap 50 and Mid Cap 50.

If you compare the small-cap index with the mid-cap index, you will realise why the small-cap should be tactical. Nifty Midcap 150 index has an average return of 14.54% in five years, higher than the small-cap index. It also fell less in different market conditions. Therefore, the concept of high-risk, high-reward doesn’t seem to hold when it comes to small-caps.

Bottom Line

When investing in index funds, you must be careful about the fund and the category you pick. The good news is that if you are a passive investor, you have index fund alternatives to major equity categories. You can now build a portfolio using only passive funds. Before selecting a fund, compare the tracking error and expense ratio.
