Mutual Fund Portfolio Overlap: Meaning, Causes, Impact, and How To Avoid It

When investing in mutual funds or stocks, it is important to understand the underlying investments in your portfolio. If you invest in multiple mutual funds, there are chances that your portfolio may have a significant overlap with another mutual fund scheme. This overlap is called mutual fund portfolio overlap.

Let’s understand what mutual fund portfolio overlap is, its causes, and how to avoid it.

What is Mutual Fund Portfolio Overlap?

Mutual fund portfolio overlap can occur when two or more mutual fund schemes hold the same stocks in their portfolio. For instance, if Fund A and Fund B both invest in stocks belonging to the same company, the portfolios of the two funds would overlap.

Some degree of overlap between mutual fund portfolios is common and sometimes inevitable, as fund managers may have similar investment strategies or investment objectives.

Causes of Mutual Fund Portfolio Overlap

The following are the factors that cause mutual fund portfolio overlap.

Similar Investment Style and Objectives

Mutual funds that follow similar investment goals and strategies often invest in the same stocks. For example, two funds focused on large-cap stocks may have several common holdings.

Industry Concentration

Mutual funds that invest a large share of their money in the same sector or industry may have overlapping holdings. For instance, two funds with high investments in pharmaceutical companies may hold many of the same stocks.

Stock Concentration

Mutual funds that invest in a limited number of stocks may overlap with other funds if they choose the same companies. The impact and level of overlap depend on the stocks they share and the amount invested in each of them.

Market Capitalisation

If you invest in multiple mutual funds that focus on a particular, such as mid-cap or small-cap stocks, they may have similar holdings to those of other funds following a similar investment approach.

Concentration Risk

Mutual fund portfolio overlap can also lead to concentration in your investment portfolio. If you invest in multiple mutual funds with significant overlap, your overall portfolio may have increased exposure to the same securities, industries, or investment objectives, leading to concentration risk.

Investment Performance

Mutual fund portfolio overlap can affect your returns because multiple funds may invest in the same stocks or sectors. If these investments perform well, you may earn higher returns. If they perform poorly, your losses may increase. Too much overlap can also reduce diversification and increase concentration risk.

Understand Your Investments

Before investing in a mutual fund, make sure you understand the fund’s investment strategy, holdings, and sector allocation. This will help you identify potential overlap with other funds in your portfolio and make informed investment decisions.

Asset Class Diversification

You must consider diversifying your portfolio across different asset classes, such as equities, bonds, and other investments, according to your financial goals and risk tolerance. This can help reduce overreliance on a single asset class.

Sector Diversification

You must diversify your investment portfolio across different sectors or industries to reduce sector concentration, which can contribute to overlap between different mutual funds in your portfolio.
