Tata MF has launched Tata Nifty Midcap 150 Momentum 50 index fund. Picks momentum stocks from the midcap universe. The back test results are stunning, far better than any of the factor products I have reviewed so far. But and there are always buts.
Usually, I add the warnings/caveats towards the end of product review post. However, the back test results for Nifty Midcap 150 Momentum 50 index are so good that I thought of starting with the caveats first. Here you go.
- Past performance may not repeat in the future.
- For this index, there is no past performance in the first place. The entire data is back tested.
- The index was launched only in August 2022. Therefore, negligible live performance data.
- If an index provider is launching an index, the back test results must be great. What is the point of launching an index has not even delivered in the back tests? Moreover, no AMC would launch products tracking an index with poor past performance.
- NSE would have evaluated multiple definitions of Midcap momentum index. They would have selected the definition of midcap momentum that delivered the best results in the back tests. The outperformance could simply a result of curve-fitting. Hence, we must take such data with a pinch of salt. Need to see longer live performance.
- Investor money will chase successful investment strategies. More money will flow into the strategy. Just this will reduce alpha (excess returns) from an investment strategy.
- This index selects stocks from universe of midcap stocks. As you go down the market spectrum, the slippages and impact cost increases. Hence, you can expect tracking error to be much higher than Nifty 50 index funds/ETFs.

What is Nifty Midcap 150 Momentum 50 index? How does it select stocks?
Nifty Midcap 150 Momentum 50 selects stocks from the universe of midcap stocks (Nifty Midcap 150).
Nifty Midcap 150 is the parent index.
Launch Date: August 16, 2022
Base Date: April 1, 2005
Rebalancing Frequency: Semi-Annual
Weight of a single stock capped at 5%
The stock picking methodology is like the Nifty 200 Momentum 30 index. From the universe of stocks, normalized momentum score is determined for each stock based on 6-month and 12-month price returns, adjusted for volatility. The stocks that have delivered over these time frames will have better momentum scores compared to stocks that have not done well.
Note that momentum stocks are not just about returns. The path is also important. Between two stocks A and B with the same price performance, the stock with a smoother rise will get a better momentum score.
Stock A: 100, 120, 155, 170, 180, 200
Stock B: 100, 150, 135, 185, 170, 200
Both stocks have gone up from 100 to 200. But stock A had a smoother rise (lower volatility). Thus, A will get a better momentum score than stock B.

An interesting observation is that Midcap Momentum has lower volatility than its parent index Nifty Midcap 150. We tend to associate momentum stocks with higher volatility.
However, if you look closely at the methodology, low volatility is an important part of stock selection in momentum index. We saw this in the review post on Nifty 200 Momentum 30 index too. The Momentum index was less volatile than its parent index (Nifty 200).

I do not have a very crisp answer here.
I like momentum investing. Both are momentum indices.
If I had to pick one Momentum index product, I would go with Nifty 200 Momentum Index fund.
Even though Nifty Midcap Momentum 50 beats Nifty 200 Momentum in returns data, I choose Nifty 200 Momentum for the following reasons.
- Nifty 200 Momentum 30 index has longer live data (since August 20). Nifty Midcap Momentum has negligible history
- It is a broader index (not just limited to midcap stocks)
- Seems more consistent (look at 5-year data)
- Less volatile (refer to Rolling risk chart)
- Will likely have lower tracking error compared to Nifty Midcap Momentum index
I think I have not yet been able to form conviction about the midcap momentum index. Thus, I am just finding ways to justify my choice. My opinion may change/evolve over a period.
How can I use Nifty Midcap 150 Index Fund in my portfolio?
If you want to use Midcap Momentum index fund in your portfolio, you can consider this part of your satellite portfolio.
You can include this fund in your midcap exposure, potentially as an alternative to actively managed midcap fund. Think Midcap Quality and Midcap Momentum could be an interesting mix for building midcap exposure.
Do not dive headlong into this fund based on back test results. Build the exposure gradually. You may also be able build conviction along the way. No investment strategy outperforms all the time. In fact, no investment strategy can sustain alpha over the long term if the strategy does not go through periods of underperformance. Conviction comes in handy during such adverse phases.
And yes, consider all the caveats shared at the start of this post.
