Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Principal Investment Strategies: The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets plus any borrowings in a combination of securities and other assets of utility and utility related companies. These are companies that are principally engaged in utilities operations such as providing electricity, natural gas, water, internet services, email (electronic mail), data communications, mobile and cellular infrastructure to the public. The Fund considers a company to be in or related to the utilities industry if, at the time of the investment, the Fund determines that at least 50% of the company’s assets or revenues are derived from one or more utilities or utility related functions. As part of its investment process, the Adviser seeks investment opportunities in the utility industry that may provide steady sources of current income and capital appreciation without incurring unnecessary risks. The Fund’s assets will be invested primarily in a diverse range of dividend paying common stocks within the utilities industry with sound and stable corporate structures. The Fund seeks to find utility companies that derive their revenue from utility operations with strong underlying value. The Fund seeks to select utility companies that have a proven dividend history with reliable cash flows.
In addition, the Fund may invest up to 20% of its net assets plus any borrowings in non-utility related investments, including (i) equity securities, including common stock, preferred stock and convertible preferred stock of non-utility related companies of any capitalization, whether domestic or foreign, with potential for accelerating growth, above-average growth or growth potential, increasing or consistent profitability and/or a proven history of paying consistent dividends; (ii) Master Limited Partnerships (“MLPs”), which are publicly traded partnerships typically engaged in the transport, storage, processing, refining, marketing, exploration, production and mining of minerals and natural resources, often referred to as the energy infrastructure; and (iii) fixed income securities of any grade, as well as non-rated fixed income securities, both short-term and long-term, including taxable municipal bonds, income producing convertible securities and corporate bonds. |

Strategy Portfolio Concentration [Text] | rr_StrategyPortfolioConcentration | The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets plus any borrowings in a combination of securities and other assets of utility and utility related companies. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | Principal Risks of Investing in the Utilities Fund: An investment in the Utilities Fund could lose money over short or long periods of time. You should expect and be able to bear the risk that the Utilities Fund’s share price may fluctuate within a wide range. There is no assurance that the Utilities Fund will achieve its investment objective. The Utilities Fund’s performance could be adversely affected by the following principal risks. Each risk summarized below is a principal risk of investing in the Utilities Fund and different risks may be more significant at different times depending upon market conditions or other factors.
Russia’s recent military incursions in Ukraine have led to, and may lead to additional, sanctions being levied by the United States, European Union and other countries against Russia. Russia’s military incursion and the resulting sanctions could adversely affect global energy and financial markets and thus could affect the value of the Fund’s investments, even beyond any direct exposure the Fund may have to Russian issuers or the adjoining geographic regions. The extent and duration of the military action, sanctions and resulting market disruptions are impossible to predict, but could be substantial. Any such disruptions caused by Russian military action or resulting sanctions may magnify the impact of other risks described in this “Principal Risks of Investing in the Utilities Fund” section.
In addition, an outbreak of infectious respiratory illness caused by a novel coronavirus known as COVID-19 was first detected in December 2019 and has now been transmitted globally. In March 2020, the World Health Organization announced that COVID-19 could be characterized as a pandemic. The impact of COVID-19, and other infectious illness outbreaks that may arise in the future, could adversely affect the economies of many nations or the entire global economy, individual issuers and capital markets in ways that cannot necessarily be foreseen. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The duration of the COVID-19 outbreak and its effects cannot be determined with certainty. The value of the Fund and the securities in which the Fund invests may be adversely affected by impacts caused by COVID-19 and other epidemics and pandemics that may arise in the future. For additional information regarding Market Risk, refer to “Market Risk” in the section titled “Additional Information About the Investment Objective, Strategies and Related Risks” in the Fund’s prospectus.
Suitability: An investment in the Fund may be suitable for long-term investors who wish to invest a portion of their overall equity portfolio in a mutual fund that invests primarily in utility companies. Investors should be willing to accept the risks and potential volatility of such investments and the risks of a fund that concentrates in a single industry. |
