A momentum index fund buys the stocks that have gone up the most in the few months and keeps them until the next review. The Nifty200 Momentum 30 Index is an example. It picks 30 stocks from the Nifty 200 based on how each stock has risen over six months and twelve months.. It also adjusts for how much the stock price moves day to day. This helps level out swings.
This strategy works well when a stock that is already rising keeps rising. So momentum index funds can do better than the market in some years.. In other years they can fall behind a lot. How the index picks stocks how often it changes them and how the gains are taxed are just as important as the return in one year.
What a momentum index fund is
A momentum index fund is a fund. It does not pick stocks on its own. Instead it holds the stocks as the index it tracks at the same weights. It only trades when the index changes. Momentum is one of factors that index builders use. Other factors include quality, low volatility and value. Because of this these funds are often grouped under beta or factor investing.
How the index picks stocks
| Step | What happens |
|---|---|
| 1 | The index starts with an universe like the 200 stocks in the Nifty 200. |
| 2 | Each stock’s six-month and twelve-month price returns are divided by the deviation of its daily returns. This adjusts the return for how volatile the stock’s |
| 3 | The two scores are standardized and averaged using weights. This creates a momentum score. |
| 4 | The 30 stocks with the scores get into the index. |
| 5 | Each stock’s weight comes from its free-float market capitalization multiplied by its momentum score. |
The Nifty500 Momentum 50 Index uses the method but picks 50 stocks from the larger Nifty 500. A scheme document names the index a fund follows.
Why it matters
These indices are reviewed twice a year. Stocks that lose their momentum can stay in the index until the review. This delay is called rebalancing gap risk. New leaders only enter on review dates. Each review can change a part of the portfolio. So a momentum fund trades more than a market-cap index fund. This means trading costs, which are part of the fund.
Benefits of a momentum index fund
| Benefit | How it works |
|---|---|
| Rules-based selection | The index follows a published method. No fund manager makes judgment calls on which stocks to hold. |
| Trend capture | Stocks with recent returns get more weight. This can help in times when leaders keep leading. |
| Cost | Index funds usually charge expense ratios than actively managed funds. |
| Transparency | Holdings match the index. So the portfolio can be checked against the index rules. |
Risks of a momentum index fund
| Risk | What it means |
|---|---|
| Trend reversal | Momentum can fail quickly if market leadership changes.. Reversals can be sharp. |
| Concentration | With 30 stocks each stock and each sector has a higher weight than in a broad market index. |
| Rebalancing lag | Stocks that lose momentum stay in the index until the review. |
| Higher turnover costs | More buying and selling leads to trading costs inside the fund. |
| Tracking error | The fund’s returns can differ from the index due to costs and cash holdings. |
What returns to expect
Returns from momentum funds vary a lot from one period to another. You cannot predict them from one year of data. Momentum funds tend to do in rising markets, where the top stocks keep leading. They struggle when markets turn and earlier leaders fall. The factsheet shows the fund’s returns over one, three and five years. It compares them to the index and to an index like the Nifty 500. The standard deviation shows how uneven the returns have been.
Tax on momentum index funds
Momentum index funds mostly invest in equity. So they are taxed like equity-oriented funds. The tax happens when you sell your units. The rebalancing inside the fund does not create a tax bill for the investor.
| Holding period | Tax on the gain |
|---|---|
| 12 months or | 20% short-term capital gains tax |
| More than 12 months | 12.5% on gains above ₹1.25 lakh in a financial year |
What investors should take from this
A momentum index fund is a factor tilt. It is not a replacement for a market index fund. How much of your portfolio it takes determines how much a weak momentum phase matters. The tax rules also make the holding period part of your decision.
