Editor's Note: Over a three-year period, funds in sectors tend to move together, but they can diverge greatly in week-to-week performance. As this article focuses on one-week returns, it is not intended to agree with our ratings that examine time periods of as long as three years. Therefore, it is likely that either the winners or losers may disagree with our longer-term outlook. As a fund being up or down in any given week is not a reason to buy or sell that fund, please be sure any potential investment fits your long-term portfolio goals.
