Risk [Text Block]	Risks Relating to Communication Services Industries or Groups of Industries. The Fund’s assets will have significant exposure to one or more industries or groups of industries in the Communication Services Sector, which means the Fund will be more affected by the performance of such industries or groups of industries than a fund that is more diversified. Market or economic factors impacting companies in industries or groups of industries within the Communication Services Sector that rely heavily on technological advances could have a major effect on the value of the Fund’s investments. The value of stocks of communication services companies and companies that rely heavily on technology is particularly vulnerable to research and development costs, substantial capital requirements, product and services obsolescence, government regulation, and domestic and international competition, including competition from foreign competitors with lower production costs. Stocks of communication services companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in industries or groups of industries within the Communication Services Sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel. While all companies may be susceptible to network security breaches, certain companies in industries or groups of industries within the Communication Services Sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.
