According to reports from the source, investors holding 5 mutual funds may inadvertently own the same 20 stocks 5 times over. This duplication can significantly impact portfolio efficiency and potentially increase costs through unnecessary redundancy. The analysis highlights how fund selection can lead to unintended overlap that may not be immediately apparent to investors. Recent research shows that 20 mutual funds can result in exposure to at least 500 stocks, reducing portfolio diversification to essentially buying the entire index rather than achieving true diversification across different asset classes.
As reported by the source, investors can now access free portfolio overlap calculators to identify and address costly fund duplication. These tools allow users to input their fund holdings and receive detailed analysis of overlapping securities across different investment vehicles. The calculators help investors understand how their diversified fund strategy may be creating unintended concentration in specific stocks, with recent studies showing that each basket containing 20 funds can have hundreds of unique stocks after eliminating duplication.
According to the source, the duplication can result in significant cost increases through unnecessary redundancy in stock holdings. The analysis suggests that investors may be paying multiple management fees for the same underlying securities, potentially reducing overall portfolio efficiency. Recent data shows that operational costs increase substantially when managing large portfolios with multiple schemes, requiring investors to monitor multiple funds, assess performance, and make complex decisions about fund manager changes and exits.
Financial experts emphasize that diversification across asset classes is more important than simply increasing fund numbers. Vivek Banka from GoalTeller warns against 'deworsification' - adding investments that increase complexity without materially improving risk management. For investors with ₹5 crore portfolios, experts recommend limiting mutual fund schemes to 10-15 maximum while focusing on diversification across asset classes including fixed income, precious metals, and international investments. The key is to achieve diversification of asset classes rather than simply adding more funds, as equity-dominated portfolios can remain exposed to broad market risks even with hundreds of individual stock holdings.
