What’s Driving the Buzz Around Momentum Index Funds?
Momentum index funds are quickly gaining popularity among Indian investors who want to ride the wave of high-performing stocks. These funds follow a simple rule: invest in companies showing strong recent performance, and drop the ones that fall behind.
As Indian markets evolve and passive investing grows, more retail and institutional players are turning to momentum-based strategies for potential outperformance.
So, what’s really driving everyone’s excitement about momentum index funds? In this article, we’ll take a close look at the main reasons why interest in these funds is on the rise.
What are Momentum Index Funds?
Momentum index funds in India follow predefined indices such as Nifty 200 Momentum 30 index funds or Nifty 500 Momentum 50 index funds.
They select only the top 30 or 50 stocks from Nifty 200 or Nifty 500 based on each stock’s “momentum score.” This score combines its recent 6‑month and 12‑month price returns, adjusted for daily volatility.
Every six months, the index is rebalanced to retain only the highest‑momentum stocks. These funds aim to ride current market winners using a simple, rule‑based, transparent, and cost‑efficient strategy.
What’s Fueling the Buzz Around Momentum Index Funds
Here’s what’s making momentum index funds a hot topic among Indian investors right now.
1. Proven Outperformance of Momentum Strategies
In India, the momentum factor has consistently beaten traditional benchmarks. Momentum‑based equity funds surged 75.8 % in calendar 2021, versus 16.5 % for the Nifty 500, then delivered 46 % in 2023 (vs 25.2 %) and 25.6 % in 2024 (vs 15 %) during market recovery phases.
Over the past 11 years, momentum investing ranks among the top risk‑adjusted factor strategies, outperforming value and low‑volatility in Sharpe-based rankings.
That track record helps explain why momentum funds now lead India’s market recovery, attracting strong inflows and rising investor confidence.
2. New Momentum Index Products Live on Platforms
Multiple asset managers in India offer live, widely digitally accessible momentum‑based index funds for retail investors. For example:
- UTI’s Nifty 200 Momentum 30 fund (launched March 10, 2021) now manages ₹ 8,543 cr AUM with a low 0.43 % expense ratio and invests in the top‑30 high‑momentum large‑mid caps.
- SBI Mutual Fund rolled out its SBI Nifty 200 Momentum 30 Index Fund on July 9, 2025, tracking the same index.
- Since September 30, 2024, Nippon India has offered the Nifty 500 Momentum 50 Index Fund with ₹959 cr AUM in 50 momentum stocks via SIPs and online apps, affordably and securely.
Investors can now access momentum equity exposure easily via mainstream passive platforms across digital channels.
3. Surge in Inflows & Broader Fund Momentum
Fiscal 2025 saw record-high net equity inflows of ₹4.17 lakh crore in Indian mutual funds, over twice the amount in FY24, pushing equity AUM to ₹29.45 lakh crore by March 2025.
Foreign institutional investors (FIIs) reversed early-year selling and injected ₹17,000 crore into Indian equities during April and May 2025. Meanwhile, passive fund AUM jumped 25% year on year, reaching ₹12.11 lakh crore by May, about 17% of the entire mutual fund industry.
Finally, strong SIP inflows from retail investors expanded folios and reinforced passive styles like momentum indexing.
4. Quant Strategy + Low-Cost, Transparent Investing
Momentum index funds in India use a fixed mathematical rule: they buy top performing stocks (from Nifty 200 or Nifty 500) based on past price momentum. No human trader decides; they rebalance regularly so the strategy stays mechanical and bias-free.
Since they follow a published index, investors enjoy very low fees, typically around 0.3% to 0.8%, lower than active schemes. Every stock list, turnover, and rebalancing schedule is disclosed publicly.
This transparency appeals to digital advisors and cost-conscious retail users.
5. Structural Shift Toward Mid/Small-Cap Leaders
India’s equity leadership is shifting structurally: mid‑cap and small‑cap stocks are consistently outperforming large‑caps, driven by strong earnings, more IPOs from Tier II/III cities, and growing investor flows into these fast‑growing firms.
Over the past two decades, mid‑caps have delivered 28x returns, well above the Nifty 50, and they continue to lead on a risk‑adjusted basis in 2025.
Momentum index funds benefit by systematically rebalancing into this expanding pool of emerging leaders, capturing early rotation from large‑caps to high‑momentum mid- and small‑cap opportunities within a rules‑based framework.
Conclusion
Momentum index funds in India are gaining traction as they offer a smart, rule-based way to invest in trending stocks. With rising investor interest, growing fund options, and strong past returns, they are worth considering. However, due to their volatility, it’s best to use them as a small part of your portfolio, not the entire core.
Momentum strategies have had a strong academic backing since Jegadeesh & Titman (1993), but the implementation details matter a lot — rebalancing frequency, the look-back window, and how you handle the short-term reversal effect all meaningfully affect returns. For most retail investors the bigger practical issue is tax drag from frequent rebalancing, which is why the fund structure matters as much as the strategy itself.
Great overview of momentum investing. The behavioral psychology angle is fascinating — most retail investors understand the concept of buying low and selling high but momentum strategies essentially codify the opposite instinct. What I find interesting for fintech builders is that the difficulty users have with momentum strategies (holding winners, cutting losers) is exactly the emotional gap products like this need to bridge. Are you seeing demand for automated momentum exposure through robo-advisors, or is this still primarily a DIY investor conversation?
