Risk [Text Block]	Market RiskYour investment in Fund shares represents an indirect investment in the REIT shares and other securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account any reinvestment of Fund dividends and distributions.
Common Stock Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Common Stock RiskCommon stocks are subject to special risks. Although common stocks have historically generated higher average returns than fixed-income securities over the long-term, common stocks also have experienced significantly more volatility in returns. Common stocks may be more susceptible to adverse changes in market value due to issuer specific events or general movements in the equities markets. A drop in the stock market may depress the price of common stocks held by the Fund. Common stock prices fluctuate for many reasons, including changes to investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or the occurrence of political or economic events affecting issuers. For example, an adverse event, such as an unfavorable earnings report, may depress the value of common stock in which the Fund has invested; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks held by the Fund. Also, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. The common stocks in which the Fund will invest are typically subordinated to preferred securities, bonds and other debt instruments in a company’s capital structure in terms of priority to corporate income and assets, and, therefore, will be subject to greater risk than the preferred securities or debt instruments of such issuers. In addition, common stock prices may be sensitive to rising interest rates as the costs of capital rise and borrowing costs increase.
Real Estate Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Real Estate Market RiskSince the Fund concentrates its assets in companies engaged in the real estate industry, your investment in the Fund will be closely linked to the performance of the real estate markets. Property values may fall due to increasing vacancies or declining rents resulting from unanticipated economic, legal, cultural or technological developments. Real estate company prices also may drop because of the failure of borrowers to pay their loans and poor management, and residential developers, in particular, could be negatively impacted by falling home prices, slower mortgage origination and rising construction costs.
REIT Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	REIT RiskIn addition to the risks of securities linked to the real estate industry, REITs are subject to certain other risks related to their structure and focus. REITs generally are dependent upon management skills and may not be diversified. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. By investing in REITs through the Fund, a shareholder will bear expenses of the REITs in addition to expenses of the Fund. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law, or (ii) maintain their exemptions from registration under the Investment Company Act of 1940 (the “1940 Act”). The above factors may also adversely affect a borrower’s or a lessee’s ability to meet its obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting its investments.
Foreign Non US and Emerging Market Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Foreign (Non-U.S.) and Emerging Market Securities RiskRisks of investing in foreign securities, which can be expected to be greater for investments in emerging markets, include currency risks, future political and economic developments, including but not limited to, international wars or conflicts, instability in regions such as Asia, Eastern Europe and the Middle East, terrorism, natural disasters and public health emergencies (including epidemics and pandemics), and possible imposition of foreign withholding or other taxes on income or proceeds payable on the securities (including trading and tariff arrangements and restrictions, sanctions and cybersecurity attacks). In addition, there may be less publicly available information about a foreign issuer than about a domestic issuer, and foreign issuers may not be subject to the same accounting, auditing and financial recordkeeping standards and requirements as domestic issuers. Securities of companies in emerging markets may be more volatile than those of companies in more developed markets. Emerging market countries generally have less developed markets, exchanges and economies and, in some countries, less mature governments and governmental institutions. Foreign securities markets and exchanges may be less liquid, more volatile and less subject to governmental supervision than in the United States. Political developments in foreign countries or the United States may at times subject such countries to sanctions from the U.S. government, foreign governments and/or international institutions that could negatively affect the Fund’s investments in issuers located in, doing business in or with assets in such countries. Investing in securities of companies in emerging markets may entail special risks relating to potential economic, political or social instability and the risks of expropriation, nationalization, confiscation, trade sanctions or embargoes, exchange controls, the imposition of restrictions on foreign investment, the lack of hedging instruments, restrictions on repatriation of capital invested or from problems in security registration or settlement and custody. Furthermore, custody practices and regulations abroad may offer less protection to investors, such as the Fund, and the Fund may be limited in its ability to enforce contractual rights or obligations. The securities and real estate markets of some emerging market countries have in the past experienced substantial market disruptions and may do so in the future. The economies of many emerging market countries may be heavily dependent on international trade and have thus been, and may continue to be, adversely affected by trade barriers, foreign exchange controls and other protectionist measures imposed or negotiated by the countries with which they wish to trade.
Risks of Investing in Japan [Member]
Prospectus [Line Items]
Risk [Text Block]	Risks of Investing in JapanThe growth of Japan's economy has historically lagged that of its Asian neighbors and other major developed economies. Japan also remains heavily dependent on international trade, such as oil imports, and thus susceptible to the adverse effects of trade barriers, exchange controls, and other measures imposed or negotiated by the countries with which they trade. China has become an important trading partner with Japan, yet the countries' political relationship has at times become strained. Should political tension increase, it could adversely affect the Japanese economy, especially the export sector, and destabilize the region as a whole. The Japanese yen has been susceptible to fluctuations at times and any increase in its value may cause a decline in exports that could weaken the Japanese economy. Japan has, in the past, intervened in the currency markets in an to attempt to maintain or reduce the value of the yen. Japanese intervention in the currency markets could cause the value of the yen to fluctuate sharply and unpredictably and could cause losses to investors. Structural social and labor market changes, including an aging workforce, population decline and traditional aversion to labor mobility may adversely affect Japan's economic competitiveness and growth potential. Natural disasters, such as earthquakes, volcanoes, typhoons or tsunamis, could occur in Japan or surrounding areas and could negatively affect the Japanese economy.
Foreign Currency and Currency Hedging Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Foreign Currency and Currency Hedging RiskAlthough the Fund will report its NAV and pay dividends in U.S. dollars, foreign securities often are purchased with and make any dividend and interest payments in foreign currencies. Therefore, the Fund’s investments in foreign securities will be subject to foreign currency risk, which means that the Fund’s NAV could decline solely as a result of changes in the exchange rates between foreign currencies and the U.S. dollar. In particular, Russia’s military invasion of Ukraine has weakened a number of Euro-area currencies and increased volatility of currencies in general. Certain foreign countries may impose restrictions on the ability of issuers of foreign securities to make payment of principal, dividends and interest to investors located outside the country, due to blockage of foreign currency exchanges or otherwise. The Fund may, but is not required to, engage in various investments that are designed to hedge the Fund’s foreign currency risks, including foreign currency forward contracts, foreign currency futures contracts, put and call options on foreign currencies and foreign currency swaps. Such transactions may reduce returns or increase volatility, perhaps substantially.
Small and Medium Sized Companies Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Small- and Medium-Sized Companies RiskCompanies in the real estate industry tend to be small- to medium-sized companies in relation to the equity markets as a whole. There may be less trading in a smaller company’s stock, which means that buy and sell transactions in that stock could have a larger impact on the stock’s price than is the case with larger company stocks. Smaller companies also may have fewer lines of business so that changes in any one line of business may have a greater impact on a smaller company’s stock price than is the case for a larger company. Further, smaller company stocks may perform differently in different cycles than larger company stocks. Accordingly, real estate company shares can, and at times will, perform differently than large company stocks.
Preferred Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Preferred Securities RiskThere are various risks associated with investing in preferred securities. These risks include deferral and omission of distributions; credit risk; subordination to bonds and other debt securities in a company’s capital structure; interest rate risk; prepayment and extension risk; call, reinvestment and income risk; liquidity risk; limited voting rights; and special redemption rights.
Market Disruption and Geopolitical Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Disruption and Geopolitical Risk Geopolitical and market events (including armed conflicts, terrorism, natural disasters, public health emergencies, trade disputes, tariffs, sanctions, and political or economic instability) can cause significant volatility in global markets and may adversely affect the Fund’s investments. Disruptions to supply chains, sharp movements in commodity prices, and changes in investor sentiment or credit conditions may negatively impact issuers, sectors, or entire regions, even those not directly involved in the originating event.Recent examples include the ongoing conflicts in Ukraine and the Middle East, and increasing political polarization around issues such as trade policy, monetary policy and the U.S. debt ceiling. The rapid development and regulation of artificial intelligence technologies may also introduce uncertainty. The scope, severity, and duration of these risks are difficult to predict, but they could materially reduce the value of the Fund’s investments.
Regulatory Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Regulatory Risk Legal and regulatory developments may adversely affect the Fund. The regulatory environment for the Fund is evolving, and changes in the regulation of investment funds and other financial institutions or products (such as banking or insurance products), and their trading activities and capital markets, or a regulator’s disagreement with the Fund’s interpretation of the application of certain regulations, may adversely affect the ability of the Fund to pursue its investment strategy, its ability to obtain leverage and financing, and the value of investments held by the Fund. The U.S. government has proposed and adopted multiple regulations that could have a long-lasting impact on the Fund and on the fund industry in general. These regulations or any laws and regulations that may be adopted in the future may restrict the Fund’s ability to engage in transactions or raise additional capital and/or increase overall expenses of the Fund. Additional legislative or regulatory actions may alter or impair certain market participants’ ability to utilize certain investment strategies and techniques. The Fund and the instruments in which it invests may be subject to new or additional regulatory constraints in the future. These regulations and actions may adversely affect both the Fund and the instruments in which the Fund invests and its ability to execute its investment strategy. For example, climate change regulation (such as decarbonization legislation, other mandatory controls to reduce emissions of greenhouse gases, or related disclosure requirements) could significantly affect the Fund or its investments by, among other things, increasing compliance costs or underlying companies’ operating costs and capital expenditures. Similarly, regulatory developments in other countries may have an unpredictable and adverse impact on the Fund.
Cyber Security Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Cyber Security RiskWith the increased use of technologies such as the Internet and artificial intelligence including machine learning technology and generative artificial intelligence such as ChatGPT (collectively, “AI Technologies”), and the dependence on computer systems to perform necessary business functions, the Fund and its service providers (including the Advisor and Subadvisors (defined below)), and their own service providers, may be susceptible to operational and information security risks resulting from cyber-attacks and/or other technological malfunctions. In general, cyber-attacks are deliberate, but unintentional events may have similar effects. Cyber-attacks include, among others, stealing or corrupting data maintained online or digitally, preventing legitimate users from accessing information or services on a website or company system, misappropriating or releasing confidential information without authorization (including personal data), gaining unauthorized access to digital systems for purposes of misappropriating assets and causing operational disruption. Cyber-attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service. New ways to carry out cyber-attacks continue to develop. There may be an increased risk of cyber-attacks during periods of geopolitical or military conflict, and geopolitical tensions may increase the scale and sophistication of deliberate cyber security attacks, particularly those from nation-states or from entities with nation-state backing. Successful cyber-attacks against, or security breakdowns of, the Fund, the Advisor, a Subadvisor, or a custodian, transfer agent, or other affiliated or third-party service provider may adversely affect the Fund or its shareholders. Each of the Fund, the Advisor and the Subadvisors may have limited ability to detect, prevent or mitigate cyber-attacks or security or technology breakdowns affecting the Fund’s third-party service providers. While the Fund has established business continuity plans and systems designed to detect, prevent or reduce the impact of cyber-attacks, such plans and systems are subject to inherent limitations.
Shareholder Concentration Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Shareholder Concentration Risk The Fund may have one or more large shareholders or a group of shareholders investing in classes of Fund shares indirectly through an account, platform or program sponsored by a financial institution. In addition, a large number of shareholders collectively may purchase or redeem Fund shares in large amounts rapidly or unexpectedly (collectively, such transactions are referred to as “large shareholder transactions”). Investment and asset allocation decisions by such financial institutions regarding the account, platform or program through which multiple shareholders invest may result in subscription and redemption decisions that have a significant impact on the assets, expenses and trading activities of the Fund. Such a decision may cause the Fund to sell assets (or invest cash) at disadvantageous times or prices, increase or accelerate taxable income and/or gains or transaction costs and may negatively affect the Fund’s NAV, performance, or ability to satisfy redemptions in a timely manner. The effects of taxable income and/or gains resulting from large shareholder transactions would particularly impact non-redeeming shareholders who do not hold their Fund shares in an IRA, 401(k) plan or other tax-advantaged plan. The Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. A number of circumstances may cause a Fund to experience large redemptions, such as changes in investors’ circumstances; changes in the eligibility criteria for a Fund or share class of the Fund; liquidations, reorganizations, repositionings, or other announced Fund events; or changes in investment objectives, strategies, policies, risks, or investment personnel.
Other Investment Companies Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Other Investment Companies Risk To the extent the Fund invests a portion of its assets in investment companies, including open-end funds, closed-end funds, exchange-traded funds (“ETFs”) and other types of pooled investment funds, those assets will be subject to the risks of the purchased investment funds’ portfolio securities, and a shareholder in the Fund will bear not only his or her proportionate share of the Fund’s expenses, but also indirectly the expenses of the purchased investment funds. Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment funds. Risks associated with investments in closed-end funds also generally include market risk, leverage risk, risk of market price discount from NAV, risk of anti-takeover provisions and non-diversification risk. In addition, restrictions under the 1940 Act may limit the Fund’s ability to invest in other investment companies to the extent desired. Rule 12d1-4 and other applicable rules under Section 12(d)(1) of the 1940 Act permit an investment company to invest in other investment companies beyond the statutory limits, subject to certain conditions. This could affect the Fund’s ability to redeem its investments in other investment companies, make such investments less attractive, cause the Fund to incur losses, realize taxable gains distributable to shareholders, incur greater or unexpected expenses or experience other adverse consequences.
Active Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Active Management RiskAs an actively managed portfolio, the value of the Fund’s investments could decline because the financial condition of an issuer may change (due to such factors as management performance, reduced demand or overall market changes), financial markets may fluctuate or overall prices may decline, or the Advisor’s investment techniques could fail to achieve the Fund’s investment objective or negatively affect the Fund’s investment performance.
