And the final snapshot

This has important implications from portfolio construction perspective

From the risk and returns analysis shared above, it is easy to see that Nifty Next 50 index fund behaves more like a midcap fund (Nifty Midcap 150) than a large cap fund (Nifty 50).

While the analysis is fine, how do we use this information?

We add different kinds of funds to your domestic equity portfolios to get exposure to the entire market spectrum. Large cap, midcap, multicap, small cap etc. That increases the number of funds in the portfolio and adds to the portfolio complexity.

Now, we know that Nifty Next 50 index behaves more like a midcap fund.

Therefore, if you prefer simple portfolios, say just a couple of index funds, Nifty 50 index could be your large cap exposure and Nifty Next 50 fund could be a proxy for your midcap exposure. And that’s it. No need to other funds.

This is not to say that you shouldn’t use midcap funds in your portfolio. You can use mid and small cap funds too. And we can’t expect Nifty Next 50 to mirror the performance of midcap funds. Nifty Next 50 and Nifty Midcap 150 are not identical twins. If we look at the calendar year performance chart, the difference in annual returns is over 10% a few times. Moreover, that Nifty Next 50 is closer to Nifty Midcap 150 (than Nifty 50) does not make it a midcap fund.

However, if you are after simplicity, you can view Nifty Next 50 index fund in this new light and consider it as proxy for the midcap exposure in the portfolio.

Disclosure: I use more than a couple of index funds to structure equity portfolios. Additionally, my understanding of statistical concepts such as standard deviation/correlation is not upto the mark. However, I believe the charts shown give a fair idea.
