Should you invest in multi-asset allocation funds in 2026?
Are multi-asset funds a costly convenience in 2026?
Building a well-diversified mutual fund portfolio is key to reducing risk and maximising returns. But many investors fall into the trap of over-diversifying by purchasing too many funds that end up overlapping. When multiple funds in your portfolio invest in the same securities, it can negate the benefits of diversification. So how do you know if your mutual funds are overlapping?
In this blog, we’ll explain what overlapping funds are, why they can undermine your investment strategy, and how to identify overlapping securities in your mutual fund portfolios.
We’ll also discuss tools that can analyse your funds and the steps you can take to reduce redundancy.
Overlap refers to when two or more of your mutual funds invest in the same stocks. For example, if Fund A and Fund B both have 5% invested in Tata stock, that’s considered a 5% overlap.
This frequently happens because the top 100 stocks comprise about 60% of total equity assets under management in the mutual fund industry. Fund managers tend to flock to the same big name stocks.
Too much overlap can undermine the purpose of diversification. If much of your portfolio is duplicating the same holdings, you lose out on the risk management benefit of spreading your money across a variety of assets.
Overlap can also cause you to overpay. If you’re doubling down on expensive funds that hold the same stocks, those redundant fees can eat into your returns.
The main risk of mutual fund portfolio overlap is increased exposure to specific stocks, which can amplify portfolio volatility and potential losses.
High Concentration in Top Stocks: About 60% of the industry’s equity Assets Under Management (AUM) is invested in the top 100 stocks, leading to a high concentration risk.
Overlap in Various Categories:
These facts point to a lack of diversification and potential increased risk due to market volatility impacting these concentrated stocks.

Here’s how you can use 1 Finance’s Mutual Fund Portfolio calculator to find out whether you have an overlapping portfolio.
1.Visit : https://1finance.co.in/calculator/portfolio-review and add funds you want to compare.
For instance:

2. Once you’ve entered the mutual funds you want to compare, proceed by clicking on the “Find Overlap” button. You will get a report for overlapping funds along with their ratio.

In the example provided, you would observe that many funds have substantial overlap between each other.
For example, there’s a 57% overlap between ICICI Prudential Bluechip Fund and HDFC Top 100 Fund, and other specified percentages of overlap between pairs of funds like Axis Bluechip Fund and HDFC Top 100 Fund, and so on.
These can result in counterproductive outcomes.
Reduced Diversification: One of the main purposes of investing in multiple mutual funds is to benefit from diversification, reducing the risk of having too much exposure to a single stock or sector.
A high overlap means that the investor is not gaining as much diversification as they might think because a large portion of the funds is invested in the same stocks.
Risk Concentration: If the overlapping stocks perform poorly, all funds could be negatively impacted, potentially leading to higher losses for an investor who holds both funds, compared to if they held funds with less overlap.
Redundant Costs: Mutual funds charge management fees and other expenses. If two funds have a high overlap, an investor may be paying multiple sets of fees without receiving the benefit of diversification.
Impact on Portfolio Strategy: For investors seeking to build a balanced and diversified portfolio, a high overlap might mean they need to reassess their investments and possibly choose additional funds or securities that offer exposure to different assets.
Investors who are aware of such overlap might choose to invest in just one of the overlapping funds or look for other funds that provide exposure to different stocks or sectors to achieve a more diversified portfolio.
