Why India's Best Financial Habit Has a Hidden Flaw
December 2025 | Qode Advisors LLP
A Remarkable Achievement
Every month, over ₹29,000 crore flows into Indian mutual funds through SIPs. That's roughly ₹1,000 crore every single day from millions of retail investors who've embraced the discipline of systematic investing.
By November 2025, India's mutual fund industry had crossed ₹81 lakh crore in assets under management. SIP contributions alone reached ₹29,445 crore that month, making it one of the highest ever recorded. Over 10 crore SIP accounts now exist across the country.
This is behaviour modification at scale. A decade ago, convincing retail investors to stay invested through market volatility seemed impossible. Today, SIP inflows have become so consistent that they provide a structural counterweight to foreign institutional outflows.
Consider the numbers: Total SIP flows for 2025 stood at ₹3.03 lakh crore through November, up from ₹2.69 lakh crore in all of 2024. SIP assets under management crossed ₹16.53 lakh crore, now accounting for over one-fifth of the entire mutual fund industry's assets.
AMFI's 'Mutual Funds Sahi Hai' campaign, combined with digital platforms that made investing frictionless, created a genuine cultural shift. Indians who once parked savings in fixed deposits and gold are now regular equity investors.
The habit is right. But is the habit enough?
What SIPs Get Right
SIPs elegantly solve two problems. First, the 'when' problem by investing regularly, you avoid the impossible task of timing the market. Second, the 'how much' problem by committing to a fixed amount, you build discipline into your finances.
Dollar cost averaging, the mechanism underlying SIPs, means you automatically buy more units when prices are low and fewer when prices are high. Over time, this smooths out your average purchase price and removes the emotional burden of deciding when to invest.
For millions of Indians, this has been transformative. The monthly SIP has become as routine as paying rent or EMIsa financial habit that runs on autopilot.
But here's what the SIP success story doesn't address: the problems that emerge once the habit is in place.
The Three Hidden Flaws
1. The Allocation Problem
SIPs don't solve the 'what to buy' problem. That's left entirely to the investor. And the data suggests many are getting it wrong.
Look at what happened to sectoral and thematic funds in 2025. These funds targeting specific industries like manufacturing, infrastructure, and technology attracted record inflows in 2024 when those themes were performing well. By March 2025, inflows had collapsed 97% from February levels, falling from ₹5,712 crore to just ₹170 crore.
This wasn't just a temporary pause. Between July and November 2025, sectoral and thematic fund inflows swung wildly from ₹9,426 crore in July to ₹3,893 crore in August to ₹1,221 crore in September, before partially recovering. Such volatility reveals a troubling pattern: investors are chasing recent performance, entering themes after they've already run up, and exiting after disappointment.
SIPs compound mediocrity as efficiently as they compound wealth.
2. The Portfolio Overlap Problem
There's another allocation mistake that's harder to spot: the illusion of diversification.
Many investors run multiple SIPs believing they're diversified. Six funds, eight funds, sometimes twelve funds each carefully selected from different fund houses. But when you examine the underlying holdings, you often find the same stocks appearing across portfolios.
Two large-cap funds from different asset management companies might both hold HDFC Bank, Reliance Industries, ICICI Bank, and Infosys in their top ten positions. Run SIPs into both, and you're not diversifying..you're doubling your concentration in the same stocks while paying fees to two fund houses.
The problem intensifies with multiple flexicap or multicap funds. These funds have broad mandates to invest across market capitalisations, but their largest holdings often converge on the same proven names. An investor running SIPs into three flexicap funds might find that 60-70% of their combined portfolio is invested in overlapping stocks.
This isn't diversification. Its concentration is disguised as diversification with the added cost of multiple expense ratios.
3. When SIPs Stop Feeling Like Buying the Dip
Perhaps the least discussed flaw emerges slowly, over years of disciplined investing. The very success of your SIP habit creates a new problem.
When you start investing, dollar cost averaging works beautifully. A ₹25,000 monthly SIP into a portfolio worth ₹1 lakh represents 25% of your holdings. When markets fall 20%, your next SIP meaningfully lowers your average cost. You're buying the dip in a real way. Watching your portfolio decline stings, but you can see your monthly contribution making a tangible difference.
Fast forward ten years. Your disciplined investing has built a corpus of ₹50 lakh. That same ₹25,000 monthly SIP now represents just 0.5% of your portfolio. When markets fall 20%, your portfolio drops by ₹10 lakh. Your monthly SIP? It barely moves the needle.
This is the mathematical reality that few SIP advocates discuss. As your portfolio grows, the percentage contribution of each SIP instalment shrinks. The averaging effect that made early drawdowns psychologically bearable becomes almost irrelevant.
A 40% market correction on a ₹1 crore portfolio means watching ₹40 lakh evaporate. Your ₹25,000 SIP, faithfully continuing through the carnage, adds back just 0.25% per month. It would take over 130 years of SIP contributions to recover what you lost assuming markets stayed flat.
Early in your investing journey, SIPs provide both financial and psychological benefits. Later, the financial mechanics remain, but the psychological comfort of 'averaging down' largely disappears. This is precisely when investors need the most conviction and when they have the least mathematical reassurance.
The Stoppage Signal
The SIP stoppage data tells a sobering story.
In January 2025, something unprecedented happened: 61.33 lakh SIPs were discontinued while only 56.19 lakh new ones were registered. For the first time in years, outstanding SIP accounts actually declined falling from 10.32 crore to 10.27 crore. The SIP stoppage ratio crossed 100%, meaning more investors were abandoning their SIPs than starting new ones.
The trend continued. By November 2025, the stoppage ratio remained elevated at approximately 75.5% meaning for every 100 new SIPs registered, 75 were discontinued.
What's driving these stoppages? Part of it is the market correction that began in late 2024. The Nifty 50 and Sensex fell over 10% from their September 2024 peaks, and smaller stocks fell harder. Investors who had entered after the June 2024 election rally suddenly found themselves staring at losses.
But here's the deeper issue: investors who picked funds wisely - genuinely diversified across factors, not just tickers were better positioned to stay the course. Those who had concentrated bets in recent outperformers were the first to panic.
Even the best habit fails when the underlying allocation disappoints.

The Questions Worth Asking
Before your next SIP instalment, consider these questions:
Do your SIPs provide genuine diversification? Not just across fund names, but across market caps, sectors, and factors that drive returns. Check the actual overlap in your holdings.
Are you chasing last year's winners? Thematic and sectoral funds that performed well in 2024 may not repeat. Historical performance, especially over short periods, is a poor predictor of future returns.
What's your actual exposure? If you're running multiple SIPs, calculate the combined weight of your top 20 holdings. You might be surprised by how concentrated your portfolio actually is.
Is your allocation aligned with your risk capacity? Not with recent headlines or what performed well last quarter. A 25-year-old saving for retirement and a 50-year-old approaching it need very different portfolios.
How will you handle a major drawdown when your corpus is large? The psychological comfort of averaging down diminishes as your portfolio grows. Do you have the conviction to stay invested when your monthly SIP can't meaningfully offset losses?
The Case for Systematic Allocation
Here's what we believe: the discipline of SIPs combined with the rigour of systematic allocation creates something more robust than either can achieve alone.
SIPs bring the behavioural discipline and the commitment to invest regularly regardless of market conditions. That's invaluable. But the 'what to buy' decision shouldn't be left to gut feeling, recent performance, or the latest NFO theme.
Rules-based allocation grounded in data rather than stories solves the selection problem. Multi-factor frameworks can ensure genuine diversification across the return drivers that actually matter: value, momentum, quality, low volatility. Not just diversification across ticker symbols that happen to hold the same underlying stocks.
The Indian retail investor has already proven they can build the habit. The next frontier is ensuring that habit translates into genuine wealth creation, not just activity that feels productive.
The Bottom Line
SIPs remain one of the most powerful tools available to Indian investors. The monthly flows prove that millions have internalised the discipline of regular investing. That's a genuine achievement.
But discipline without direction compounds whatever you put into it mediocrity as efficiently as excellence. The 75% stoppage ratio isn't a failure of the SIP mechanism. It's a signal that allocation decisions matter.
The investors who'll build lasting wealth aren't just the ones who keep investing. They're the ones who invest in the right things, for the right reasons, with a framework that survives market cycles.
The habit is right. The question is whether the allocation is.
