Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 13.5% of the average value of its portfolio.

Expense Example [Heading] rr_ExpenseExampleHeading Example
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading] rr_StrategyHeading Investments, Risks, and Performance

Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The fund will normally invest at least 80% of its net assets (including any borrowings for investment purposes) in the common stocks of companies engaged in any facet of media and telecommunications, including the Internet, publishing, movies, cable/satellite TV, telephones, cellular services, technology, and equipment. Generally, the fund invests in companies in the large- to mid-capitalization range, but may invest in small companies, including privately held and newly public companies.

Stock selection is based on fundamental, bottom-up analysis that seeks to identify companies with good appreciation prospects. The portfolio manager may use both growth and value approaches to stock selection. When assessing opportunities among growth-oriented stocks, the portfolio manager generally seeks to identify companies with capable management, attractive business niches, sound financial and accounting practices, and a demonstrated ability to increase revenues, earnings, and cash flow consistently. In looking for value stocks, the portfolio manager will seek companies whose current stock prices appear undervalued in terms of earnings, projected cash flow, or asset value per share, and with growth potential temporarily unrecognized by the market. The portfolio manager also seeks to invest in companies whose stock prices may be temporarily depressed.

In pursuing its investment objective, the fund has the discretion to deviate from its normal investment criteria. These situations might arise when the fund’s adviser believes a security could increase in value for a variety of reasons, including an extraordinary corporate event, a new product introduction or innovation, a favorable competitive development, or a change in management.

The fund’s portfolio may hold stocks of either U.S. or non-U.S. companies, and may at times consist of a relatively small number of holdings. Although the fund typically invests a greater portion of its assets in U.S. stocks than international stocks, there is no limit on the fund’s investments in international securities.

The fund may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into more promising opportunities.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The fund will normally invest at least 80% of its net assets (including any borrowings for investment purposes) in the common stocks of companies engaged in any facet of media and telecommunications, including the Internet, publishing, movies, cable/satellite TV, telephones, cellular services, technology, and equipment.
Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock As with any mutual fund, there is no guarantee that the fund will achieve its objective. The fund’s share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund are summarized as follows:

Active management risk The fund is subject to the risk that the investment adviser’s judgments about the attractiveness, value, or potential appreciation of the fund’s investments may prove to be incorrect. If the investments selected and strategies employed by the fund fail to produce the intended results, the fund could underperform in comparison to other funds with similar objectives and investment strategies.

Risks of stock investing Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. The value of a stock in which the fund invests may decline due to general weakness in the stock market or because of factors that affect a particular company or industry. In addition, the relatively small number of holdings in which the fund invests could cause it to be more volatile than comparable funds with a more diversified portfolio.

Any investments in the stocks of privately held companies and newly public companies involve greater risks than investments in stocks of companies that have traded publicly on an exchange for extended time periods. There is significantly less information available about these companies’ business models, quality of management, earnings growth potential, and other criteria that are normally considered when evaluating the investment prospects of a company. Private placements and other restricted securities held by the fund are generally considered to be illiquid and are difficult to value since there are no market prices and less overall financial information available. The adviser evaluates a variety of factors when assigning a value to these holdings, but the determination involves some degree of subjectivity and the fund’s value may differ from the value assigned by other mutual funds holding the same security.

Market capitalization risk Because the fund may invest in companies of any size, its share price could be more volatile than a fund that invests only in large companies. Small- and medium-sized companies often have less experienced management, narrower product lines, more limited financial resources, and less publicly available information than larger companies. Larger companies may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods, and they may be less capable of responding quickly to competitive challenges and industry changes.

Industry risk A fund that focuses its investments in specific industries or sectors is more susceptible to developments affecting those industries and sectors than a more broadly diversified fund. Because the fund invests significantly in media and telecommunications companies, the fund may perform poorly during a downturn in those industries. Media and telecommunications companies can be adversely affected by, among other things, changes in government regulation, intense competition, dependency on patent protection, and rapid obsolescence of products and services due to product compatibility or changing consumer preferences.

International investing risk Investing in the securities of non-U.S. issuers involves special risks not typically associated with investing in U.S. issuers. International securities tend to be more volatile and less liquid than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, international investments are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S.

Emerging markets risk The risks of foreign investing are heightened for securities of issuers in emerging market countries. Emerging market countries tend to have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries. In addition to all of the risks of investing in foreign developed markets, emerging markets are more susceptible to governmental interference, local taxes being imposed on foreign investments, restrictions on gaining access to sales proceeds, and less liquid and less efficient trading markets.
