Dividend Paying Investments Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Dividend-Paying Investments Risk. The Fund’s investments in dividend-paying securities could cause the Fund to underperform other funds. Securities that pay dividends, as a group, can fall out of favor with the market, causing such securities to underperform securities that do not pay dividends. Depending upon market conditions and political and legislative responses to such conditions, dividend-paying securities that meet the Fund’s investment criteria may not be widely available and/or may be highly concentrated in only a few market sectors. In addition, issuers that have paid regular dividends or distributions to shareholders may not continue to do so at the same level or at all in the future. This may limit the ability of the Fund to produce current income.
Geographic Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Geographic Risk. If the Fund focuses its investments in securities of issuers located in a particular country or region, the Fund may be subjected, to a greater extent than if investments were less focused, to the risks of volatile economic cycles and/or conditions and developments that may be particular to that country or region, such as: adverse securities markets; adverse exchange rates; adverse social, political, regulatory, economic, business, environmental or other developments; or natural disasters.
Industry Concentration Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Industry Concentration Risk. The Fund concentrates its investments in the real estate industry, which has historically experienced substantial price volatility. This concentration subjects the Fund to greater risk of loss as a result of adverse economic, business, political, environmental or other developments than if its investments were diversified across different industries.
Large Shareholder Transactions Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Large Shareholder Transactions Risk. The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund's net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund's performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund's current expenses being allocated over a smaller asset base, leading to an increase in the Fund's expense ratio.
Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Risk. The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors, governments or countries and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Events such as war, military conflict, geopolitical disputes, acts of terrorism, social or political unrest, natural disasters, recessions, inflation, rapid interest rate changes, supply chain disruptions, tariffs and other restrictions on trade, sanctions or the spread of infectious illness or other public health threats, or the threat or potential of one or more such events and developments, could also significantly impact the Fund and its investments.
Real Estate Industry Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Real Estate Industry Risk. Risks associated with investments in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. The real estate industry is particularly sensitive to economic downturns. The values of securities of companies in the real estate industry may go through cycles of relative under-performance and out-performance in comparison to equity securities markets in general.
Real Estate Investment Trusts REITs Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Real Estate Investment Trusts (“REITs”) Risk. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price.
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	Loss of money is a risk of investing in the Fund.
Risk Not Insured Depository Institution [Member]
Prospectus [Line Items]
Risk [Text Block]	An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency.
Risk Nondiversified Status [Member]
Prospectus [Line Items]
Risk [Text Block]	Non-Diversification Risk. The Fund is non-diversified, meaning that it is permitted to invest a larger percentage of its assets in one or more issuers or in fewer issuers than diversified mutual funds. Thus, the Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio, and may be more susceptible to greater losses because of these developments.
