Using Sector Funds to Construct Diversified Mutual Fund Portfolios


Sector funds have become popular among investors who want to construct diversified mutual fund portfolios. Sector funds are mutual funds that concentrate their investments in one particular industry or sector of the economy, such as healthcare, technology, or energy. The goal of sector funds is to provide investors with exposure to a specific sector of the economy that they think will outperform the overall market.

One of the advantages of using sector funds to construct a diversified mutual fund portfolio is that it allows investors to take a focused approach to investing. Instead of investing in a broad-based mutual fund that includes a mix of sectors, investors can select a few sector funds that they think will perform well in the coming years. This allows investors to focus on their strongest investment ideas, rather than trying to be a jack-of-all-trades.

Another advantage of sector funds is that they can help investors manage risk. By investing in a variety of different sectors, investors can reduce their overall portfolio risk. For example, if an investor only invests in technology stocks and the tech sector experiences a downturn, their portfolio will also suffer. However, if the investor has also invested in healthcare, energy, and other sectors, their losses in the tech sector will be offset by gains in other sectors.

There are several ways that investors can use sector funds to construct diversified mutual fund portfolios. The first way is to use a core-satellite strategy. This involves investing in a broad-based mutual fund, which serves as the core of the portfolio. The investor then adds sector funds as satellite investments around the core mutual fund. The core mutual fund provides broad diversification, while the satellite funds provide exposure to specific sectors.

Another way to use sector funds is to build a thematic portfolio. This involves selecting a specific theme or trend that the investor thinks will perform well in the coming years, such as clean energy or artificial intelligence. The investor then selects sector funds that are focused on industries that are related to the theme. For example, an investor who is bullish on clean energy might invest in a renewable energy sector fund, a green building sector fund, and a sustainable agriculture sector fund.

A third way to use sector funds is to build a momentum portfolio. This involves selecting sectors that have been performing well in recent years and investing in sector funds that are focused on those sectors. Investors who use a momentum strategy are essentially betting that the sectors that have been performing well will continue to outperform in the coming years.

One of the challenges of using sector funds to construct diversified mutual fund portfolios is that it is difficult to predict which sectors will outperform in the coming years. For example, in 2020, few investors would have predicted that the healthcare and technology sectors would be the top-performing sectors. This is why it is important for investors to do their homework and conduct thorough research on the sectors and funds they are considering investing in.

Another challenge of using sector funds is that they can be more volatile than broad-based mutual funds. Because sector funds concentrate their investments in a single industry or sector, they are more susceptible to fluctuations in that industry or sector. This can lead to greater volatility and higher risk. However, investors can reduce their risk by investing in a variety of different sector funds.

In conclusion, sector funds can be an effective tool for constructing diversified mutual fund portfolios. They allow investors to take a focused approach to investing and manage risk by investing in a variety of different sectors. However, investors should be aware of the challenges of using sector funds, including higher volatility and the difficulty of predicting which sectors will outperform in the coming years. By doing their homework and conducting thorough research, investors can use sector funds to build diversified portfolios that align with their investment goals and risk tolerance.
