‘Sector funds are too risky.’ ‘I doubled my money with Fidelity Select Technology in 12 months!’ ‘Avoid sector funds.’ If all of this sounds confusing, you are not alone. Sector funds are among the more misused and misunderstood investments. So, how should you use sector funds?

Before looking at one of the uses of sector funds in detail, let’s review what sector funds really are: Sector funds confine their investments to a particular sector of the economy. Fidelity Select Healthcare (NDQ: FSPHX) is an example of a sector fund. By focusing on stocks of companies in the healthcare sector, the price moves of this fund are more dependent on factors that impact the healthcare sector rather than the economy as a whole. Demographic change, such as increasing age of the population, is an example of a factor that particularly drives investments in healthcare. By diversifying its assets across over 60 companies within the healthcare sector, Fidelity Select Healthcare provides investors with the opportunity to benefit from secular trends driving the demand for healthcare while mitigating company-specific risks such as failure of clinical trials conducted by a particular company.

Let’s now look at a high-potential approach of using sector funds. Using sector funds to create a diversified mutual fund portfolio

By allocating assets across a group of sector funds, investors can effectively create a diversified mutual fund portfolio using sector funds. This approach gives the investor flexibility to over-weight or under-weight certain sectors versus broadly diversified indexes such as the S&P 500®.

To implement this active approach to money management, it helps to have a diverse group of sector funds to choose from. Fidelity Investments manages 41 sector funds under the Fidelity Select Portfolios® umbrella which makes this family of sector funds well-suited for this purpose. By dividing assets across, say, 8 sector funds in the Fidelity Select Portfolios, e.g., Fidelity Select Biotechnology (NDQ: FBIOX), Fidelity Select Computers (NDQ: FDCPX), Fidelity Select Energy Service (NDQ: FSESX), Fidelity Select Home Finance (NDQ: FSVLX), Fidelity Select Medical Delivery (NDQ: FSHCX), Fidelity Select Multimedia (NDQ: FBMPX), Fidelity Select Retailing (NDQ: FSRPX), and Fidelity Select Wireless (NDQ: FWRLX), one can build a customized diversified portfolio. With each of the sector fund managers actively scouting for the best investment ideas within their sectors, this cluster of Fidelity Select Portfolios packs a lot of power into your diversified portfolio.

Other mutual fund families that provide a relatively wide choice of sector funds include ProFunds and Rydex Funds. Exchange traded sector funds such as Select Sector SPDRs, iShares, and Sector HOLDRS, that trade on the American Stock Exchange, can also be used to construct diversified sector fund portfolios.

The wide selection of sector funds available provides you with the ability to take advantage of changing market conditions and continually optimize the risk-reward characteristics of your diversified portfolio. To employ this approach effectively, you need to understand and follow the dynamics of the individual sectors. You must also be able to make informed decisions on sectors to select and sectors to avoid. At the end of the day, you should be right more often than wrong with the sectors you select.

AlphaProfit.com’s research suggests that by constructing diversified mutual fund portfolios using sector funds, investors have the potential to outperform the market averages on the basis of relative returns as well as risk-adjusted returns. The track-record of AlphaProfit’s model portfolios indicates the potential of this approach.

A Caveat

Diversification is one of the cornerstone principles of mutual fund investing. Sector funds that focus on high-growth sectors or narrow niches of the economy tend to be volatile. It is generally not advisable to commit a substantial portion of your total assets to a single sector fund. Maintaining adequate diversification across sectors in your overall mutual fund portfolio is good investing practice. Key Points to Remember

1. Sector funds are investment vehicles that focus their investments on a particular sector or industry group. Sector funds provide investors with an opportunity to profit from trends impacting a particular sector or industry while reducing company-specific risks.

2. High-potential diversified portfolios can be constructed by dividing assets among a group of sector funds. This active investment approach requires investors to make informed decisions on sector selection.
