Is Your Mutual Fund Portfolio Overlapping? Here’s How to Find Out

However, many investors unknowingly dilute the benefits of diversification by holding multiple funds that invest in the same securities. This overlap can increase risk, duplicate costs, and ultimately diminish portfolio performance.

Wondering if your mutual funds are overlapping?

What is Mutual Fund Portfolio Overlap?
Portfolio overlap occurs when two or more mutual funds in your portfolio invest in the same underlying stocks.

This phenomenon is common because a large proportion of mutual fund assets are concentrated in the top 100 stocks, with fund managers often gravitating toward the same high-performing companies.

Why is Overlap a Problem?
Excessive overlap in your mutual fund portfolio can undermine the core benefit of diversification. Instead of spreading risk across different asset classes and sectors, overlapping holdings lead to concentrated exposure, making your portfolio vulnerable to market volatility.

Here’s why overlap should concern you:

Reduced Diversification: Overlapping stocks concentrate your portfolio, reducing the diversification that is crucial for risk mitigation.

Higher Costs: Paying management fees for multiple funds holding similar stocks means you’re incurring redundant expenses without gaining additional diversification benefits.

Increased Risk: A downturn in a few overlapping stocks can severely impact multiple funds, amplifying losses across your portfolio.

Industry Insights on Overlapping Risks

ELSS (Equity Linked Savings Schemes): Overlap ranges from 30% to as high as 80%.

Flexi-Cap Funds: Average overlap is about 25%, with some surpassing 50%.

Such high concentration levels expose investors to undue risk and volatility.

Tracking overlapping securities across multiple mutual funds can be complex without the right tools.
