Investors considering flexi-cap and large & mid-cap mutual funds often wonder about potential duplication in holdings. Flexi-cap funds are unconstrained and can shift allocations across large-, mid-, and small-cap stocks based on market conditions, while large & mid-cap funds must maintain at least 35% in both large- and mid-cap stocks. This structural difference allows flexi-cap funds to typically lean towards large caps, often holding around 60%, while large & mid-cap funds ensure a significant mid-cap presence. Despite concerns about overlap, it is often overstated; some combinations show only about 20% overlap, which does not materially affect diversification, especially when including other fund categories. Investors are advised to diversify across different asset management companies (AMCs) to avoid concentration risks, as similar investment philosophies can lead to similar stock selections. Regular portfolio assessments are crucial, as flexibility in fund management can adapt to market changes. Ultimately, both fund types can complement each other in a well-structured portfolio, with a suggested allocation of 50-55% in large caps, 20-25% in mid caps, and the remainder in small caps.
