Momentum investing is a strategy where investors buy stocks that have already risen in price over the past 3 to 12 months, based on the idea that the rise may continue for some more time. Indian investors track this using price returns, indicators such as RSI and MACD, and rule based indices like the Nifty 200 Momentum 30. According to ET Money’s analysis of NSE data, the Nifty 200 Momentum 30 index outperformed the Nifty 50 in 10 of the last 15 years, though it has also fallen harder during market crashes, which shows why risk management is as central to this strategy as stock selection.
Many first time investors notice a stock climbing month after month and wonder why not simply follow what is already going up instead of hunting for hidden gems. That question describes momentum investing in one line. It is a strategy built on one observation: stocks that have been rising in price tend to keep rising for a while, and stocks that have been falling tend to keep falling. This article explains how momentum investing works in the Indian market, which indicators are commonly used to identify momentum stocks, how the Nifty 200 Momentum 30 index has actually performed over time, and where beginners commonly run into trouble with this approach. None of this is a recommendation to act on any particular stock or fund.
Momentum investing is a strategy in which stocks that have shown strong price gains over the past 3 to 12 months are bought, based on the idea that the trend may continue for some more time. It runs counter to the traditional buy low, sell high approach, since a momentum investor is often buying a stock that has already risen and hoping the rise continues.
This is not about finding undervalued companies. A momentum investor is not asking whether a stock is cheap. The question being asked is whether a stock is trending up and whether that trend appears strong enough to continue. Two explanations are commonly offered for why this pattern shows up in markets. Investors often react slowly to good news about a company and then follow the crowd once a trend becomes visible, which stretches a price move out over months rather than days. Once a trend draws attention, additional buyers tend to step in simply because the stock is already moving, which can push the price further in the same direction.
Two indices apply this idea using fixed rules rather than discretion. The S&P BSE Momentum Index was launched in December 2015, and the Nifty 200 Momentum 30 Index was launched by NSE Indices in August 2020, according to ET Money. Both select stocks using a set formula, which is one reason this strategy is often studied by beginners without years of experience reading balance sheets.
A momentum strategy generally follows the same sequence of steps, whether applied by an individual or built into an index.
Most momentum strategies do not scan the entire market. They work from a defined list such as the Nifty 200, which keeps the universe limited to liquid, well tracked companies.
This is typically the stock’s price return over the past 6 and 12 months. The Nifty 200 Momentum 30 index combines both periods and adjusts the score for daily price volatility, so a steady 40% rise scores higher than a choppy 40% rise with large daily swings.
Momentum Score, in simple terms, equals (Current Price minus Price 6 Months Ago) divided by Price 6 Months Ago, multiplied by 100.
Stocks are ranked from highest to lowest score, and filters are then applied. According to ET Money, the Nifty 200 Momentum 30 index only considers stocks with at least one year of listing history that are also available in the futures and options segment. These filters narrow the universe from 200 stocks to around 130.
A final list can range from 15 to 30 stocks depending on how concentrated the approach is. The index itself picks the top 30 and caps any single stock’s weight at the lower of 5% or five times its weight in the Nifty 200, which limits overexposure to one name. Equal weighting across chosen stocks is one common method individuals study, though the actual index weighs stocks using a mix of momentum score and market capitalisation.
Rebalancing happens on a fixed schedule. The Nifty 200 Momentum 30 index rebalances twice a year, in June and December. A stop loss level is often part of this process, since this strategy depends on limiting losses on positions that stop working, historically speaking.
Each step matters because momentum investing depends on discipline. Skipping rebalancing, or holding a losing stock out of attachment, works against the logic the strategy is built on.
Price return alone does not show whether a stock’s momentum is fresh or already fading. Several standard indicators are commonly used alongside it.
Indicator | What It Measures | How It’s Typically Read |
RSI (14 day) | Speed and size of recent price moves | Above 60 signals strength, 70 to 80 often overbought, below 40 signals weakness |
MACD | Gap between a fast and slow moving average | Rising histogram signals building momentum, falling signals fading |
Rate of Change | Percentage price change over a fixed period | Positive and rising confirms an upward move is still active |
ADX | Strength of a trend, not direction | Above 25 is generally read as a significant trend |
50 day vs 200 day moving average | Medium term trend direction | 50 day above 200 day, called a golden cross, is a widely watched signal |
A commonly used check looks at three things together: whether the stock is making higher highs and higher lows on the daily chart, whether RSI sits above 55 to 60 without being deeply overbought, and whether any breakout is happening on volume clearly above its 20 day average. A stock jumping 10% on unusually thin trading is generally treated as a caution sign rather than confirmation, since a single large order can move a low liquidity stock without genuine broad based buying behind it. These indicators can be tracked using a stock screener that filters by RSI, moving average crossovers, and volume together.
ET Money conducted a historical study using Nifty 50 stocks across five 6 month windows between September 2018 and September 2020.
In the September 2018 to March 2019 window, the highest 6 month return was recorded by Titan Company at 30%, followed by Divi’s Laboratories at 29%. The lowest returns in the same window were recorded by Tata Motors at negative 32% and Sun Pharmaceutical Industries at negative 30%. This is historical data and reflects what happened in that specific period; it is not a comment on how these stocks may perform going forward.
ET Money also examined what happened when the top 10 performers from each window were held for the following 6 months. Across four consecutive periods from March 2019 to March 2021, this approach returned 1%, 6%, 16%, and 36% respectively in that data set.
To illustrate how the calculation works, here is a hypothetical 100000 rupee portfolio split equally across 5 stocks at 20000 rupees each, tracked over one month. This is an illustration of the mechanics only and does not reflect any real portfolio or suggested holding.
Stock | Invested (₹) | Value After 1 Month (₹) | Gain/Loss |
Stock 1 | 20,000 | 22,000 | +2,000 |
Stock 2 | 20,000 | 19,000 | −1,000 |
Stock 3 | 20,000 | 21,500 | +1,500 |
Stock 4 | 20,000 | 18,200 | −1,800 |
Stock 5 | 20,000 | 20,600 | +600 |
The total portfolio value in this illustration moves from 100000 rupees to 101300 rupees, a change of 1.3% for the month. In a rules based momentum approach, a stock like Stock 4 that drops out of the top rankings by the next rebalancing date would typically be replaced by whichever stock newly ranks highest, independent of any personal view on the company.
Published index data offers a more grounded picture than assumptions.
According to ET Money’s analysis covering 2006 to 2020, the Nifty 200 Momentum 30 index was the highest performing index among five compared indices in 7 of those 15 years. Across the full period, it outperformed the Nifty 50 in 10 years and the Nifty 200 in 12 years. A hypothetical monthly SIP started in January 2006 into the momentum strategy would have shown roughly 16.9% annualised returns in this backtest, compared with about 11.3% for an equivalent Nifty 50 SIP. These are historical, backtested figures and do not indicate what future returns would look like.
The index has not always outperformed. In 2008, during the global financial crisis, it fell 60%, a steeper decline than the Nifty 50’s 51% fall that year. In 2009, during the recovery, it rose 65%, trailing the Nifty 50’s 72% rise. This shows the strategy has, in this data set, lagged during sharp reversals even while leading during sustained uptrends.
A separate index, the Nifty 500 Momentum 50, shows a broadly similar historical pattern over a longer period. Motilal Oswal Asset Management Company’s October 2025 factsheet states that 100000 rupees invested in this index on 1 April 2005 would have grown to about 6460826 rupees by 31 October 2025, reflecting a 22.4% CAGR, compared with about 1607869 rupees for the same investment in the Nifty 50, reflecting a 14.4% CAGR. The same factsheet states this index outperformed the Nifty 50 in 13 of the last 19 calendar years, and that it has also shown deeper and longer drawdowns than the Nifty 50.
The Nifty 200 Momentum 30 index’s sector composition also differs noticeably from a plain large cap index at any given time. ET Money’s data shows financial services made up over 35% of the Nifty 200 but under 10% of the Momentum 30 index at the time of that analysis, with a larger weight instead going toward IT, pharma, and metals, sectors that had shown strength in the prior 12 months.
Several funds apply momentum rules in a structured way rather than through individual stock picking. Based on publicly available fund data, examples include the UTI Nifty200 Momentum 30 Index Fund and the Motilal Oswal Nifty500 Momentum 50 Index Fund and ETF. Actively managed options in this category include the Samco Active Momentum Fund and the Quant Momentum Fund, which apply momentum concepts with fund manager discretion rather than a fixed formula.
According to ET Money, the Samco Active Momentum Fund’s return since inception was 27.90%, compared with 25.12% for the Nifty 500 and 15.76% for the Nifty 50 over the same window. The Quant Momentum Fund returned 41.10% between 5 July 2023 and 7 May 2024, compared with 17.65% for the Nifty 500 and 13.47% for the Nifty 50 over that same period. These figures describe past performance in specific historical windows and are not an indication of how any fund may perform in the future.
Two factors are generally worth examining when studying any fund in this category. One is the expense ratio. According to ET Money, the UTI Nifty200 Momentum 30 Index Fund runs at 0.4% to 0.5%, higher than the 0.1% to 0.2% typical for plain index funds, reflecting more frequent rebalancing. The Motilal Oswal Nifty500 Momentum 50 Index Fund’s direct plan expense ratio is listed as 0.41% in its October 2025 factsheet. The other is track record length, since several funds in this category have operated for only a few years and have not been tested across a full market cycle. This section is provided for information only; current factsheets should be checked directly, alongside guidance from a SEBI registered investment adviser.
Momentum is not limited to individual stocks. Entire sectors also move through periods of relative strength. When capital expenditure activity picks up, capital goods and infrastructure stocks have historically led for several quarters at a stretch. When interest rates fall, banking and NBFC stocks have often picked up in a similar way. Metals, autos, and IT have each shown multi quarter periods of relative strength during different market cycles in the past.
Some investors apply the same ranking logic at the sector level instead of the stock level, looking at which sector has shown the strongest recent return rather than which individual stock has. This can reduce single stock concentration risk, though the underlying risk remains similar, since sector trends can also reverse, sometimes quickly.
Momentum based approaches have historically performed well during trending markets, where a sector such as defence or IT can remain in favour for several quarters at a stretch, based on the index data discussed earlier. In such phases, this approach can capture price gains without requiring a view on the underlying business reason for the rally.
It also reduces the role of subjective judgement in stock selection, since it relies on price data rather than opinions about a company’s future prospects. Some investors use momentum strategies as a smaller, satellite portion of a portfolio alongside a more stable, long term core built from index funds. Tracking such a setup is generally easier with a portfolio tracking tool that shows returns without manual calculation each time a portfolio is reviewed.
Reversals in this strategy have historically been sharp. According to ET Money, the Nifty 200 Momentum 30 index fell about 19.5% in June 2022 alone, illustrating how quickly gains in this category can unwind.
Transaction costs tend to be higher, since more frequent buying and selling generally means more brokerage, Securities Transaction Tax, and other charges. Gains on stocks held for less than a year are taxed as short term capital gains at 20% under current Indian tax rules, which affects the net outcome of strategies involving frequent trading, compared with longer holding periods.
Fundamentals are not part of the selection process. Because this strategy is based purely on price, it can lead to exposure in companies with weaker fundamentals simply because the stock price has been rising. Behavioural factors also play a role: holding a position beyond its planned exit point, or reacting to a temporary price dip with a hurried sale, are both patterns that work against the discipline this strategy depends on.
Readers evaluating leverage in momentum related trades, or intraday trading more broadly, may find it useful to review how margin trading and its associated risks work before forming a view on their own risk tolerance.
Parameter | Momentum Investing | Value Investing |
Basis of selection | Recent price trend and relative strength | Whether a company appears priced below its underlying worth |
Holding period | A few weeks to a few months | Several months to several years |
Portfolio turnover | Generally high | Generally low |
Research focus | Price and volume data, indicators such as RSI | Financial statements and business fundamentals |
Risk profile | Historically higher volatility, sharper reversals | Generally steadier, though can remain undervalued for long stretches |
Typical use | Active participants comfortable with frequent monitoring | Longer term, patient participants |
This strategy has historically been more relevant to active participants and swing traders who have the time to track price movement, follow a rebalancing schedule, and apply rules consistently. It has also been used by investors seeking a smaller, satellite portion of a portfolio to capture medium term trends alongside a more stable long term core.
It tends to be less aligned with the needs of conservative, long term investors who prefer minimal portfolio activity, or with individuals who may find higher volatility and frequent decision making difficult to manage. Investors newer to markets often study approaches such as SIP investing in mutual funds before studying strategies such as this one that involve direct stock selection.
Momentum investing is built on the observation that stocks which have been rising in price have historically tended to keep rising for some further time, and that following such trends with a disciplined, rules based process has, in past data, produced competitive returns. Published index data supports this pattern: the Nifty 200 Momentum 30 outperformed the Nifty 50 in most years since 2006, and the Nifty 500 Momentum 50 outperformed the Nifty 50 in 13 of the last 19 years. At the same time, both indices have shown sharper declines during market downturns and involve higher transaction and tax costs than a longer term buy and hold approach. This article explains how the strategy works and what the historical data shows; it does not suggest that any reader should adopt it. Individuals considering any market strategy should assess their own financial situation and consult a SEBI registered investment adviser.
