Synopsis: If you’ve been putting away ₹10,000 every month into a mutual fund, you’ve probably wondered if you picked the right one. A recent study comparing seven major mutual fund categories over a full decade found some surprising winners — and some steady, quieter performers too. Small-cap and mid-cap funds pulled ahead by a wide margin, while large-cap funds stayed calm and stable. This article breaks down what actually happened to real money, month after month, for ten straight years.
A man who sends ₹10,000 out into the world every month rarely stops to admire it. He has bills, a family, maybe a dog that needs feeding, and the money leaves his account before he can grow attached to it. And yet, ten years on, that same unremarkable habit can turn into a sum large enough to make his relatives suddenly very interested in his financial affairs.
A SIP, or Systematic Investment Plan, is simply this: a fixed sum invested into a mutual fund every month, rain or shine, rally or crash. It asks for very little attention and rewards patience instead of cleverness. An industry-wide analysis of the top five schemes across seven equity categories, based on 10-year annualised SIP returns and covering the period from July 2016 to July 2026, set out to answer a simple question: which kind of fund actually built the most wealth for someone who just kept showing up every month? The study also weighed five-year rolling returns for each category, a way of checking whether the good numbers held up across different market cycles rather than depending on a single lucky stretch.
The answer was not the same for every category, and that is the whole point of this piece. Some categories delivered thrilling annualised SIP returns and a fair share of stomach-churning dips along the way. Others plodded along sensibly, like a mule that never runs but also never falls off a cliff. The sections ahead take each category in turn, sharing what it invests in, how it performed, and the sort of investor it tends to suit.

The SIP Habit That Quietly Builds Fortunes
There is nothing dramatic about a monthly deduction. No fireworks, no headline, just a small sum leaving one account and entering another, month after month, year after year. It is the financial equivalent of watering a plant — dull work, until one day the plant is a tree.
The trick lies in something called rupee-cost averaging. When markets fall, the fixed monthly sum buys more units; when markets rise, it buys fewer. Over ten years, this evens out the bumps and lets compounding do the heavy lifting without the investor needing to time anything.
What the decade-long study revealed, however, is that the vehicle carrying that SIP mattered enormously. Two investors could follow the exact same discipline, put in the exact same ₹10,000 every month, and end up with very different fortunes purely because of where that money was parked.
A Decade-Long Study Puts Seven Fund Types to the Test
The analysis, covering the period from July 1, 2016, to July 15, 2026, examined the top five schemes in seven equity categories: Flexi Cap, Focused, Large & Mid Cap, Large Cap, Mid Cap, Multi Cap, and Small Cap. Each was judged on 10-year annualised SIP returns — the kind of number that reflects an actual investor’s actual patience, not a lucky lump-sum bet — while five-year rolling returns were used to check how consistent each category was across different market phases.
The categories were compared side by side, and the gap between the boldest and the most cautious was wide enough to raise an eyebrow. Small-cap and mid-cap schemes pulled far ahead of the rest, while large-cap funds trailed with steadier, more modest gains.
A few points worth noting about the study:
- It ranked funds strictly by 10-year annualised SIP returns, not lump-sum performance
- It compared the top five schemes within each category, not every fund on the market
- It also factored in five-year rolling returns to judge consistency, not just a single headline number
Small-Cap Funds Take the Crown
Small-cap schemes, which invest in companies ranked 251st and beyond by market size, came out as the biggest wealth creators of the decade, with the top five schemes averaging close to 23 percent in annualised SIP returns. Quant Small Cap Fund led the pack at 25.95 percent, followed by Nippon India Small Cap Fund at 22.44 percent, Axis Small Cap Fund at 20.76 percent, Union Small Cap Fund at 20.33 percent, and DSP Small Cap Fund at 20.11 percent.
These are businesses still finding their feet — some destined for greatness, others destined to disappear quietly. The wide margin by which small caps beat the more diversified and large-cap categories suggests that investors who stayed the course through the wobbles were paid handsomely for their nerve, though the same category is also known to fall hardest during market corrections.
This is not a category for those who check their portfolio daily and lose sleep over red numbers. It rewards a particular kind of investor — one with a long horizon and a short memory for bad months.
Mid-Cap Funds, Right on Their Heels
Mid-cap funds, investing in companies ranked 101st to 250th, finished a close second, with the top five schemes averaging around 21 percent in annualised SIP returns. Invesco India Mid Cap Fund led the category at 22.13 percent, followed by Edelweiss Mid Cap Fund at 21.52 percent, Nippon India Growth Mid Cap Fund at 21.04 percent, Quant Mid Cap Fund at 20.59 percent, and Motilal Oswal Midcap Fund at 20.49 percent.
These are companies past their scrappy startup years but not yet the household names that dominate the indices. They tend to grow faster than large caps while carrying noticeably more volatility than the giants at the top.
For an investor willing to tolerate a bumpier ride in exchange for stronger long-term growth, mid caps have historically offered one of the better trade-offs on the table.
Flexi-Cap Funds: The Best of Both Worlds
Flexi-cap funds, which must keep at least 65 percent of their money in equity but face no fixed split between large, mid, and small companies, averaged just over 18 percent in annualised SIP returns over the decade. Quant Flexi Cap Fund topped the category at 21.16 percent, with Parag Parikh Flexi Cap Fund, HDFC Flexi Cap Fund, JM Flexicap Fund, and Edelweiss Flexi Cap Fund also among the leaders.
The appeal here is flexibility itself. A fund manager can shift weight toward large caps when markets look shaky and lean into smaller companies when opportunity knocks, all inside a single scheme.
For someone who wants one fund to handle most of the thinking, this category offers a reasonable middle ground between adventure and caution.
Multi-Cap Funds and Their Fixed-Allocation Discipline
Multi-cap funds work on a stricter rulebook. Regulations require at least 75 percent of assets in equity, with a minimum of 25 percent locked into each of large-cap, mid-cap, and small-cap stocks. Despite the rigid structure, the category still delivered solid results, with the top five schemes averaging close to 18 percent in annualised SIP returns — a shade behind Small Cap, Mid Cap, and Flexi Cap, but comfortably ahead of the more conservative categories. Quant Multi Cap Fund led the pack at 18.98 percent, with Nippon India Multicap Fund, ICICI Prudential Multicap Fund, Invesco India Multicap Fund, and Baroda BNP Paribas Multi Cap Fund also posting strong double-digit returns.
There is no room for a fund manager to abandon one segment entirely, however unfashionable it becomes. This rigid structure removes a certain kind of temptation — the urge to chase whatever segment is hot at the moment — and forces genuine diversification across the entire market.
It suits an investor who trusts the discipline of the rule more than the judgement of any single fund manager, and who wants guaranteed exposure to smaller companies without betting the whole portfolio on them.
Large & Mid-Cap Funds: A Steadier Middle Path
This category sits between caution and ambition, with rules requiring at least 35 percent in large-cap stocks and another 35 percent in mid-cap stocks. It occupied the middle of the rankings, with the top five schemes averaging around 18 percent in annualised SIP returns — a touch below the aggressive categories and comfortably above pure large-cap funds. Invesco India Large & Mid Cap Fund led with a 19.02 percent return, followed by Bandhan Large & Mid Cap Fund, ICICI Prudential Large & Mid Cap Fund, Quant Large and Mid Cap Fund, and HDFC Large and Mid Cap Fund.
The blend aims to combine the dependability of established companies with the growth appetite of mid-sized ones, without leaning too far into the more turbulent small-cap space.
It tends to appeal to investors who want more spark than a pure large-cap fund offers, but without fully signing up for the wilder swings that mid-cap or small-cap investing can bring on its own.
Large-Cap Funds: Slow, Steady, and Unshaken
Large-cap funds must keep at least 80 percent of their money in the top 100 companies by market size — the sort of businesses that make the news for reasons other than sudden collapse. Predictably, this category recorded the lowest average 10-year SIP returns among the seven studied, at roughly 14 to 15 percent. Nippon India Large Cap Fund was the best performer at 15.23 percent, ahead of Invesco India Largecap Fund and ICICI Prudential Large Cap Fund.
These are mature businesses with established earnings, so a fund built around them rarely produces dramatic swings in either direction. There is comfort in that, especially for money an investor cannot afford to watch shrink sharply.
It suits the cautious saver, the first-time investor easing into equities, or anyone who values a smoother ride over the chance of extraordinary returns.
Focused Funds: Fewer Bets, Bigger Convictions
Focused funds take the opposite approach to diversification. By rule, they can hold no more than 30 stocks, meaning each holding carries real weight in the portfolio. The category delivered average annualised SIP returns of about 17 percent over the decade, with ICICI Prudential Focused Equity Fund topping the list at 18 percent, ahead of HDFC Focused Fund and Quant Focused Fund.
When the fund manager is right, the results can be striking; when wrong, there is nowhere to hide behind a hundred other names. Most focused funds are generally classified as Very High Risk under SEBI’s Risk-o-Meter, though this can vary from scheme to scheme.
It suits investors who have real confidence in a particular fund manager’s judgement and are comfortable with a concentrated, conviction-led style of investing rather than broad diversification.
Why Bigger Returns Come With a Bigger Stomach for Risk
None of this means small-cap or mid-cap funds are simply better. Higher annualised SIP returns over a decade came bundled with sharper falls during corrections, and not every investor can watch a portfolio drop without pulling the plug at exactly the wrong moment.
Mutual funds remain market-linked products. There are no guarantees stitched into the paperwork, and past performance across any category is a description of what happened, not a promise of what comes next. It is also worth remembering that every figure in this piece refers to annualised SIP returns, not lump-sum returns, and actual outcomes will vary by fund, timing, and market conditions.
A few risk factors worth keeping in mind:
- Small and mid-cap schemes can fall harder and faster during market corrections
- Concentrated, focused portfolios depend heavily on one manager’s stock-picking
- Large-cap funds trade higher potential returns for a calmer ride
Picking the Right Fit for a Ten-Year Journey
There is no single category crowned the correct choice for everyone. A young investor with two decades ahead and nerves of steel may lean toward small and mid caps. Someone five years from retirement might sleep better with large caps carrying most of the weight.
Many seasoned investors simply split their SIPs across two or three categories, letting the steadier funds anchor the portfolio while the more adventurous ones chase the extra growth. It is less about finding one perfect answer and more about matching the fund to one’s own patience and timeline.
Ten years is a long stretch of ordinary Tuesdays. What this study really shows is that the investors who quietly kept their SIPs running, through good years and bad, are the ones who ended up with something worth talking about at the family dinner table.
