How many mutual funds should you hold in your portfolio?

Last Reviewed and Updated: 17 Aug 2026

The mutual fund industry in India has never been more accessible. With thousands of schemes across dozens of categories, and a new fund offer arriving seemingly every other week, investors have never had more to choose from. The problem is that this abundance has quietly created a new kind of portfolio mistake: over-diversification.

Indian retail investors are increasingly holding portfolios of 15, 20, or even 30 mutual funds simultaneously. They are adding funds without removing others. They are diversifying across categories that hold the same underlying stocks. And they are confusing the act of adding funds with the outcome of actual diversification.

So what is the right number? The answer is not a single magic figure, but there is a range that makes sense for most investors, and more importantly, there are clear principles that should govern the decision.

Before answering how many funds you should hold, it helps to understand why so many investors end up with too many. The typical journey is surprisingly consistent. An investor starts with one or two funds, usually recommended by a friend or family member. They work with a financial advisor who adds a tax-saving ELSS and a couple of thematic funds. A few months later, they read about a top-performing fund in a magazine and add it.

This accumulation happens gradually and feels rational at each step. After all, isn’t diversification good? The answer is yes, but only up to a point. Genuine diversification means reducing risk without proportionally reducing expected returns. Beyond a certain point, adding more funds does not reduce risk; it just adds complexity, costs, and confusion.

The administrative burden alone grows quickly. But the deeper problem is that a portfolio of 20 funds often provides no more genuine diversification than a portfolio of 5 or 6 funds, because the underlying holdings are substantially the same.

True diversification means holding assets that do not move in the same direction at the same time. A portfolio of 15 large cap equity funds achieves almost no diversification benefit over a portfolio of 3, because all 15 funds own variations of the same 50 to 100 large cap stocks.

The problem is that most investors conflate the number of funds they hold with the degree of diversification in their portfolio. These are very different things. A single well-chosen flexi cap fund that spans large, mid, and small caps across multiple sectors is far better diversified than 10 funds that all hold similar concentrations of the same Nifty 50 names.

Genuine diversification comes from holding funds that cover genuinely different market segments: a large cap fund or index fund, a small cap fund or mid cap fund, perhaps an international fund, and a debt component. Each of these fills a distinct economic role in the portfolio.

Fund overlap is one of the most underappreciated problems in retail investing in India. Overlap occurs when two or more funds in your portfolio hold many of the same stocks. This is extremely common in Indian equity mutual funds, particularly in the large cap and flexi cap categories, because SEBI regulations restrict large cap funds to the Nifty 100 universe.

A useful exercise is to take any two large cap or flexi cap funds in your portfolio and compare their top 10 holdings. In many cases, you will find 6 to 8 of the same stocks. At that point, you are not diversifying across funds; you are simply paying two sets of management fees for exposure to the same portfolio.

The same issue, to a lesser extent, exists in mid cap and small cap categories. Fund managers in these spaces have a wider investible universe, but many concentrate their portfolios around the same set of well-researched mid cap names.

For the vast majority of Indian retail investors, a well-constructed portfolio of 4 to 6 funds is both sufficient and optimal. Here is what that portfolio should look like:

Core Equity: One Large Cap or Index Fund

A single index fund or large cap fund forms the stable foundation. This provides exposure to India’s largest, most liquid companies and serves as the benchmark anchor. For cost-conscious investors, a Nifty 50 or Sensex index fund is the most efficient choice.

Growth Equity: One Mid Cap or Small Cap Fund

For investors with a longer time horizon and the stomach for volatility, one well-chosen mid cap or small cap fund adds meaningful growth potential beyond what the large cap component can deliver.

Diversification: One Flexi Cap or International Fund

A flexi cap fund, managed by a manager with genuine allocation conviction, can serve as the dynamic component of the portfolio. Alternatively, an international index fund adds currency diversification and exposure to growth stories outside India.

Stability: One Debt Fund

Every portfolio benefits from a debt component, both for stability and for rebalancing. A short duration or corporate bond fund gives you the flexibility to deploy capital into equity when markets correct meaningfully.

Optional: One Thematic or Sectoral Fund

If you have a high conviction view on a particular theme, whether infrastructure, consumption, or technology, a small allocation (5% to 10% of portfolio) to a sectoral fund is legitimate. But this is optional and should be sized carefully.

Beyond the mathematical redundancy, over-diversification carries costs that are often underestimated.

There is also the tax complexity. Every time you redeem units from a fund, a capital gains tax event is created. Managing the tax efficiency of a 20-fund portfolio is meaningfully harder than managing a 5-fund portfolio.

Finally, there is the monitoring burden. A good investment requires periodic review. Keeping track of 20 funds, monitoring their performance against benchmarks, tracking manager changes, and rebalancing appropriately is a significant ongoing task. Most investors do not have the time or inclination to do it properly, which means the 20-fund portfolio often goes unmonitored and unbalanced for years.

It is worth being honest with yourself about whether your current portfolio has become over-diversified. Some signs:

› You cannot name all the funds you hold without checking your app or statement.

› You hold more than two funds in the same SEBI category, for example, three large cap funds.

› You have added a fund in the last year because it appeared on a best performers list rather than because it fills a gap in your portfolio.

› Your SIP amounts are spread so thinly across funds that some receive less than Rs 500 per month.

› You have not reviewed your portfolio performance holistically in the last 12 months.

› You feel anxious about consolidating because you are not sure which funds to keep.

If more than two or three of these apply, the most valuable thing you can do for your portfolio right now is not to add another fund, but to consolidate.

Consolidating a bloated fund portfolio is not as painful as it sounds, but it does require a systematic approach. Start by grouping your funds by SEBI category. Within each category, identify your best performer based on consistent long-term returns and risk-adjusted metrics. That is the fund you keep.

Before redeeming the others, check the tax implications. Units held for more than 12 months in equity funds are taxed at 12.5% LTCG on gains above Rs 1.25 lakh annually. Plan your redemptions to stay within the annual exemption limit where possible.

For ongoing SIPs in funds you want to phase out, the simplest approach is to stop the SIP first, let the existing units mature past the 12-month exit load and tax threshold, and then redeem in a planned, tax-efficient manner.

A word specifically about index funds, because they change the calculus somewhat. Because index funds tracking the same benchmark are genuinely interchangeable, there is even less justification for holding multiple index funds in the same category than there is for active funds.

An investor who holds a Nifty 50 index fund, a Nifty Next 50 or mid cap 150 index fund, and a debt fund has a genuinely diversified, low-cost, low-maintenance portfolio that will serve most long-term investment goals well. Adding a fourth or fifth fund from the passive universe should only happen if it adds genuine exposure that is not already covered.

The passive investing approach is still relatively nascent in India compared to markets like the US. As Indian investors become more sophisticated and fee-conscious, portfolios are likely to become simpler and more index-oriented over time.

There is no single right answer that fits every investor, but the following general guidelines reflect what the evidence supports:

The Beginner Investor

If you are new to mutual funds, start with one fund and one fund only. A Nifty 50 index fund or a well-rated flexi cap fund is enough. Your first goal is to build the habit of investing through SIPs and to experience a full market cycle. Adding complexity before building the foundational habit is backwards.

The Intermediate Investor

With 3 to 5 years of investing experience, a portfolio of 4 to 5 funds covering large cap, mid or small cap, a flexi cap component, and a debt fund is a well-rounded structure. Review it annually and resist the temptation to add funds without removing others.

The Experienced Investor

If you have been investing for a decade or more and have a clear view of what role each fund plays in your portfolio, you can manage 6 to 8 funds comfortably. But the discipline to remove underperforming funds is just as important as the skill to identify good ones. A portfolio that only adds and never removes will eventually become a museum of past decisions rather than an optimised wealth-creation engine.

The question of how many mutual funds to hold is really a question about what investing is for. It is not for the pleasure of owning many funds. It is for building real wealth with real money over real time.

Four to six funds, chosen deliberately, reviewed annually, and held patiently through market cycles, will produce better outcomes than 20 funds accumulated impulsively and monitored anxiously. The discipline of subtraction is as powerful as the discipline of saving.
