How the Fund diversifies.Why it matters.

Most mutual funds make it possible for investors, including those with small- and medium-sized portfolios, to diversify their holdings at an affordable cost. Each and every Fund share represents a spread of securities, which could help lessen the impact of the fluctuations of any one security. Of course, diversification cannot prevent fluctuations and possible market loss, but it is recommended as a wise investment step.

Since the Energy Alternatives Fund emphasizes holdings in the specific area of sustainable investing, it diversifies by hunting for opportunities around the globe and by including three types of energy-related investments: eco-technology leaders, critical-path companies, and resource-based investments (see "three-tiered sustainable investing strategy").
