When a financial advisor or a knowledgeable friend looks at that list of fifteen funds, a strange pattern slowly uncovers itself.
The first fund is a large-cap equity fund, which holds big IT and banking companies as its top investments.
The second is a bluechip fund, but it also has those same big IT and banking companies, just in a different order.
The third fund is a flexi-cap fund, and 80% of its investments are exactly the same.
The fourth is an index fund that tracks the Nifty 50, which means it includes the same big companies yet again.
The fifth is a tax-saving fund, which has almost the identical structure. That makes five funds, but so far, it is actually just one single portfolio repeated under five different names.
Looking further, there are mid-cap and small-cap funds that overlap with each other by 60% to 70%. After that come sectoral funds like IT, Pharma, and Banking which are already heavily included in the large-cap funds. Finally, there are some thematic funds, whose structure is not much different from the rest.
The final conclusion is that the hidden truth behind these fifteen funds is that this portfolio is just a repetition of four to five sectors: IT, Banking, Pharma, FMCG, and Energy. Everything else is just the same old product in different packaging.
Understanding The Truth Through Numbers
It is easy to explain all of this in words, but the real shock comes when the actual numbers are laid out. Suppose the total investment is ₹10,00,000, and it is divided across fifteen funds which means an average of only ₹65,000 to ₹70,000 per fund. Now, if we look at the combined sector allocation of these fifteen funds, the picture looks like this:
Banking and Financial Services: 32%
Information Technology (IT): 28%
Pharmaceuticals (Pharma): 12%
FMCG: 10%Other Sectors: 18% (scattered across various small and large sectors)
This clearly means that more than 60% of the money depends on just two sectors: IT and Banking. If both these sectors hit a major roadblock at the same time for instance, if a global recession hits the IT industry while rising interest rates put pressure on the banking sector then 12 to 13 out of the 15 funds will crash simultaneously. Despite having fifteen funds, the risk remains as concentrated as if there were only two or three funds. Numbers can be deceptive; percentages tell the real story.
Now, on the other hand, if that same one million rupees is invested in just five well-chosen funds: one large-cap, one flexi-cap, one mid-cap, one debt fund, and one international fund the sector and asset-class allocation looks much more balanced. Equity is at sixty percent, debt at twenty-five percent, and international investment at fifteen percent. In this, the combined share of IT and banking stays limited to thirty to thirty-five percent, and the debt and international portions provide stability to the overall portfolio. Five funds, but real diversification; fifteen funds, but false diversification this difference becomes very clear from the numbers.
The Hidden Burden of Taxes and CostsHaving 15 different funds is not just risky; it also hurts you financially through taxes and transaction costs. Every mutual fund has its own exit load (exit fee) and its own buying and selling dates. When it is time to calculate your capital gains tax, you have to do 15 different calculations for 15 different funds.
If you sell some funds within a year, you have to pay Short-Term Capital Gains Tax. If you sell them after a year, Long-Term Capital Gains Tax applies. When you have fewer funds, it is easy to manage this planning. You can easily decide when to sell which fund and how much profit to show in a financial year. However, with 15 funds, this tax planning becomes almost impossible.
Additionally, every fund charges an expense ratio (management fee). Even if this fee looks small for a single fund, your money is split across many overlapping funds. As a result, this cost is deducted repeatedly from your total returns. You end up paying multiple times for funds that are essentially doing the same thing. In short, investors keep paying extra costs for the exact same market exposure without even realising it.
A Successful Example of Five Funds
To see the opposite (positive) picture, let's look at a realistic example. Imagine an investor who originally had 12 to 13 mutual funds, but one year they decided to clean up their portfolio completely. They checked the holdings of every fund, found the overlapping stocks, and slowly sold off 8 funds keeping only 5 funds:
One large-cap index fund
One flexi-cap fund
One mid-cap fund
One short-duration debt fund
One international fund that invests in the US market
What happened after this change?
First: Tracking the portfolio became very easy. Instead of checking 15 fact sheets every three months, they only had to check 5.
Second: Over-concentration in specific sectors dropped. The share of IT and banking went down from 60% to 35%.
Third: When the IT sector crashed heavily in one year, the damage to this 5-fund portfolio was much lower than the damage to a 15-fund portfolio, because the debt and international parts kept the balance.
Most importantly: Annual tax planning and portfolio rebalancing could now be finished in a single afternoon meeting, whereas before, it used to be a week-long headache.
Model Portfolios for Different Investors
Every investor's needs are not the same, so there is no single answer to "how many funds are enough." Even so, some general frameworks can be useful.
For an investor who has just started and has a limited amount for monthly investment, two to three funds are enough. One flexi-cap fund that flexibly invests in both large and mid-cap stocks, and one debt or hybrid fund that provides stability. In the initial stage, simplicity is the biggest advantage.
For an investor with moderate experience who now wants to structure their investments better, a framework of four to six funds is ideal: a large-cap or index fund, a flexi-cap fund, a mid or small-cap fund (depending on risk tolerance), a debt fund, and, if possible, an international fund. This framework is the most balanced for most long-term investors.
For investors who are close to retirement or prioritize capital safety, the portfolio structure is a bit different. The equity portion is reduced while the share of debt and safe instruments is increased, but the number of funds is still kept at just four to five. The core principle remains the same: diversification comes from asset allocation, not from the number of funds.
True Diversification vs. False Diversification
In the financial world, a term is used: "Diworsification," which is a blend of the words "Diversification" and "Worse." It means that in the name of bringing variety, the portfolio actually becomes worse and more complicated. True diversification means investing across different asset classes such as equity, debt, gold, and real estate. It means having a real spread across various sectors like IT, banking, pharma, consumer goods, and infrastructure. It means having a balanced presence across different market capitalizations, and where possible, having exposure to different geographic markets.
On the other hand, false diversification means buying the same sector repeatedly under different names, merely increasing the number of funds while keeping the underlying structure the same, operating under the misconception that "more funds equal lower risk," and investing solely based on marketing without reading the fact sheet of each fund.
This confusion does not happen overnight. It builds up slowly over the years, and there are a few common reasons for it:
The "More is Safer" Misconception: Many investors believe that the more funds they have, the safer their investment is. In reality, diversification depends on portfolio structure, not the number of funds. Ten funds that all invest in the same thing are no safer than a single fund; instead, they make the portfolio more complicated and harder to manage.
Conflicting Advice from Multiple Sources: Investors visit different banks and agents, and each one suggests their own "best fund," but no one looks at the entire portfolio as a whole. As a result, every new fund ends up overlapping with the previous ones.
The Impact of Marketing: New funds are launched with catchy names like Focused Fund, Innovation Fund, or Future Leaders Fund. These names sound unique, but their underlying structure is often the same old thing. Investors invest based on the name rather than looking at the actual portfolio structure.
Chasing Past Returns: When a certain fund gives good returns, investors put more money into it and buy other similar-looking funds. This is momentum chasing, not a real strategy.
How to Check for True Diversification
Now the question arises: how do you know if your portfolio is truly diversified? You can follow a few simple yet effective steps:
Check the Top Holdings:
First, write down the top ten to fifteen holdings of each fund, which are easily available on the fact sheet.
Find Repeated Companies: Create a simple list with company names on one side and check which funds hold those companies. If the same company appears repeatedly across five or six funds, it is a clear sign of a lack of true diversification.
Combine Sector Allocations:
Look at the sector-wise allocation given in each fund's fact sheet (such as how much is in IT, how much in banking, etc.) and combine them for all your funds. If IT and banking together make up more than 60-70%, it becomes obvious that your portfolio is heavily concentrated in just these two sectors.
Check Across Asset Classes: Simply having equity funds does not mean diversification. Therefore, you need to check whether you also have exposure to debt, gold, real estate, and international investments.
Define the Fund's Role: Finally, ask a simple question to every fund: "What unique role does this fund play in my portfolio?" If the answer is unclear, or if the answer is the same as another fund, that fund is probably unnecessary.
Nowadays, many free online tools are available that help check portfolio overlap. By entering the fund names, it becomes clear within a few minutes how many common holdings two funds share. For instance, if two funds have an overlap of more than 70%, keeping both funds doesn't make much sense because they are investing in almost the exact same thing, just under different names.
How Many Funds Are Enough?
The question naturally arises: how many funds are actually enough? There is no single, rigid answer to this, but a general guideline can certainly be provided.
For an ordinary investor, four to six well-chosen funds are usually sufficient. This can include:
One large-cap fund
One flexi-cap fund
One mid-cap or small-cap fund
One debt fund
And, if necessary, one international fund
Why is this enough? The reason is simple:
Every fund plays a distinct role.
Portfolio management becomes easy.
Tracking and rebalancing become hassle-free.
Tax calculation becomes simpler.
Most importantly, confusion is reduced and decision-making becomes clear.
Once the number of funds crosses ten to fifteen, management turns into a burden. Reading the performance report of each fund, calculating taxes, and making timely decisions becomes almost impossible.
One simple rule to remember here is that diversification is not about throwing money in different directions, but about having a clear, distinct purpose for every investment. This becomes much easier to understand if we imagine a garden. If someone plants a hundred different saplings, but all of them are of the exact same type, just planted in different pots, that is not true diversity. True diversity means different types of plants that bloom in different seasons and grow to different heights, which together create a balanced ecosystem.
Investing is just the same. Five carefully chosen funds that have clear roles and complement each other are always better than fifteen confused funds.
One Last Thought
Next time you think about buying a new fund, it is helpful to ask yourself one simple question: "What does this fund bring to my portfolio that is not already there in my existing funds?"
If you have a clear answer, buying that fund might make sense. But if the answer is unclear, or if it is just "this looks like another good option," it is probably wiser to add that money to your existing funds instead.
Ultimately, the success of your investment does not depend on the number of funds, but on their quality and clarity. Diversification is a strategy, not just a numbers game, and truly understanding this difference is real financial wisdom.
Moreover, reading the annual statement of every fund, checking each one's returns over different time periods, and deciding how much of which fund to sell during rebalancing all of this work becomes many times harder as the number of funds increases.
Frequently Asked Questions
1. What is "diworsification"?
Diworsification is a playful financial term that describes a situation where an investor believes they are reducing risk by adding more mutual funds to their portfolio, but actually ends up complicating it and worsening their overall structure due to heavy stock overlapping.
2. How many mutual funds should I realistically hold?
For most individual investors, 4 to 6 well-chosen funds are more than enough. A balanced portfolio typically consists of a large-cap or index fund, a flexi-cap fund, a mid/small-cap fund, a debt fund, and optionally an international fund.
3. Does having 15 mutual funds mean my risk is lower?
No. If your 15 funds hold the same underlying companies or concentrate heavily on the same sectors (like IT and Banking), your risk is just as high as if you held only 2 or 3 funds. True diversification comes from asset allocation across different asset classes, market caps, and sectors not from a high count of fund names.
4. How can I check if my mutual funds have overlapping stocks?
You can look up the monthly fact sheets provided by your Asset Management Company (AMC) to check the top 10–15 stock holdings of each fund. Alternatively, you can use free online portfolio overlap checker tools to see the exact percentage of shared holdings between your funds.
5. Why is managing a high number of mutual funds a burden during tax season?
Every mutual fund has its own unique purchase dates, exit loads, and capital gains calculations. When you hold 15 different funds, tracking short-term and long-term capital gains, handling timely rebalancing, and planning taxes becomes an unnecessarily complicated, time-consuming chore.
