The Indian stock market, which has been witnessing significant fluctuations in recent times, has led to a surge in investments in equity mutual funds. However, a recent study has revealed that investing in multiple equity mutual funds across different categories may not always lead to better diversification. This is because many of these funds have a high portfolio overlap, meaning they invest in the same set of stocks. For instance, two funds from the same asset management company have been found to have a portfolio overlap of nearly 80%.
This overlap can have a significant impact on the overall performance of an investor's portfolio, especially during times of market volatility like the recent fluctuations in the Sensex and Nifty. The market impact of such overlap can be substantial, as it can lead to a concentration of risk in a particular set of stocks, rather than spreading it across a diverse range of assets. As a result, investors may not be able to reap the benefits of diversification, which is a key principle of investing. For the common investor, this means that it is essential to carefully evaluate the portfolio of each mutual fund before investing, rather than simply relying on the category or type of fund.
By doing so, investors can make informed decisions and avoid inadvertently concentrating their risk in a particular set of stocks. Ultimately, a well-diversified portfolio is crucial for long-term financial success, and investors must be aware of the potential pitfalls of portfolio overlap in order to achieve their investment goals.
