One goal of almost every investor who is actively managing their portfolio is to outperform the major market averages. Otherwise, a simple buy and hold strategy with index funds can get you to the same performance as the markets. This becomes a more attractive goal in that if you look at the recent market performance, it has been pretty dismal. For example, for the seven years ending the in February of 2008, the S&P 500 averaged under 1% a year, or even including the dividends it averaged about 2% a year.

Fortunately, Fidelity Investments has already identified a family of sector funds well suited for a trend trading strategy. They are known as the Fidelity Select Funds. This is a popular investment vehicle that is followed by several investment newsletters. They offer over 40 different sector funds that are diversified relative to one another. They only have a minimum holding period of 30 days, which turns out to be very well suited to a sector rotation strategy. In addition, the minimum initial investment is only $2500, so it's in the range of most investors.

One well publicized approach to using the Select Funds for a sector rotation strategy has been used for years, and continues to work well today even though it's been publicly available for over 10 years. The approach is straightforward:

1) Set up a spreadsheet or other way of tracking the 25 day (or 5 week) percentage price change for all of the Select Funds. Be sure to correct for dividend distributions, which typically happen in April and December for these funds.

2) Buy the fund with the highest percentage change over the last 5 weeks.

3) Hold that fund for a minimum of 30 calendar days to avoid the early redemption fees (of 0.75%).

4) After 30 days, if the current holding is no longer the top fund, exchange it for the currently top ranked fund. If your current holding is still the top fund, continue to hold it until it drops from the top position.

5) After a trade again hold your fund for a minimum of 30 days.

You'll find that this system is simple, yet has outperformed the S&P over the last 7 years by 5% a year, which is consistent with its long term performance.

Of course, any system that is in the market 100% of the time will do better in bull markets and experience volatily, and this is no exception. This system does not have a much better drawdown than the major indices. During the bear market years of 2000 to 2002 it experienced a drawdown of almost 50%, just as the major indices did. In spite of that it came back to all time highs in 2006. But be aware that it can be a wild ride at times.
