Real Estate Market And Related Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Real Estate Market and Related Risk. Since the Fund concentrates its assets in the real estate industry, your investment in the Fund involves many of the risks of investing directly in real estate such as declining real estate values, changing economic conditions and increasing interest rates. The value of the Fund’s holdings in real estate exposed companies may be affected negatively by factors unrelated to real estate markets.
REIT Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
REIT Risk. REITs are pooled investment vehicles which include equity REITs and mortgage REITs.

Equity REITs invest the majority of their assets directly in real property and derive income primarily from the collection of rents. Equity REITs can also realize capital gains by selling property that has appreciated in value.

Mortgage REITs invest the majority of their assets in real estate mortgages and derive income from the collection of interest payments.

Like investment companies, REITs are not taxed on income distributed to shareholders provided they comply with certain requirements of the Internal Revenue Code of 1986, as amended (the “Code”). The Fund will indirectly bear its proportionate share of expenses incurred by REITs in which the Fund invests in addition to the expenses incurred directly by the Fund. The Fund will be subject to risks similar to those associated with the direct ownership of real estate, including: declines in the value of real estate, risks related to general and local economic conditions, dependency on management skill, heavy cash flow dependency, possible lack of availability of mortgage funds, overbuilding, extended vacancies of properties, increased competition, increases in property taxes and operating expenses, changes in zoning laws, losses due to costs resulting from the clean-up of environmental problems, liability to third parties for damages resulting from environmental problems, casualty or condemnation losses, lost rents due to public health crises, limitations on rents, changes in neighborhood values and the appeal of properties to tenants, changes in interest rates and changes in the tax laws.
Additionally, equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may be affected by the quality of any credit extended. REITs are dependent upon management skills, are not diversified, and are subject to heavy cash flow dependency, default by borrowers and self-liquidation. REITs are also subject to the possibilities of failing to qualify for tax free pass-through of income under the Code and failing to maintain their exemption from registration under the Investment Company Act of 1940, as amended (the “1940 Act”).

REITs, and in particular, mortgage REITs, are also subject to interest rate risks. When interest rates decline, the value of a REIT’s investment in fixed rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a REIT’s investment in fixed rate obligations can be expected to decline. In contrast, as interest rates on adjustable-rate mortgage loans are reset periodically, yields on a REIT’s investment in such loans will gradually align
themselves to fluctuate less dramatically in response to interest rate fluctuations than would investments in fixed rate obligations.

Investments in REITs may also be subject to limited financial resources, infrequent or limited trading, and abrupt or erratic price movements.
The distributions the Fund receives from REITs generally will be taxable as ordinary income (to the extent that they come from mortgage interest and rents), rather than qualifying for the lower rate on qualified dividends.

Investment In Smaller Companies Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Investment in Smaller Companies Risk. The Fund may be focused on smaller companies (those companies with a market capitalization of less than $1 billion). Smaller real estate company stocks can be more volatile and speculative than, and perform differently from, larger real estate company stocks. Smaller companies tend to have limited resources, products, and market share and are dependent on a smaller management group than larger companies. As a result, their share prices tend to fluctuate more than those of larger companies. Their shares may also trade less frequently and in limited volume, making them potentially less liquid. The prices of small company stocks may fall regardless of trends in the broader market.
Leverage Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Leverage Risk. The Fund may use leverage in executing its investment strategy. Leverage will increase the volatility of the Fund’s performance and its risk. The amount of leverage may not exceed 33-1/3% of the Fund’s total assets less its liabilities other than borrowings. The amount of the Fund’s borrowings, and the interest rates at which the Fund borrows, in particular, will affect the operating results of the Fund. There can be no assurance that a leveraging strategy will be successful.
Short Sales Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Short Sales Risk. The Fund may engage in short sales of securities and index funds in executing its investment strategy. Short sales may not exceed 30% of the Fund’s total assets. Short sales may occur if the Adviser determines an event is likely to have a downward impact on the market price of a company’s securities. Such practices can, in certain circumstances, substantially increase the impact of adverse price movements on the Fund’s portfolio. Short sales may involve substantial risk and leverage. Short sales expose the Fund to the risk that it will be required to buy the security sold short (also known as “covering” the short position) at a time when the security has appreciated in value, thus resulting in a loss to the Fund. The Fund may incur expenses in selling securities short. A short sale of a security involves the risk of a theoretically unlimited increase in the market price of the security, which could result in an inability to cover the short position or a theoretically unlimited loss.
Index Non-Correlation Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Index Non-Correlation Risk. The Fund does not attempt to mimic the composition or performance of any index, including any equity REIT indices. The Fund’s investment process will not take into consideration the weightings or composition of any indices, including any equity REIT indices. As a result, there is a significant risk that the performance of the Fund will deviate from that of any particular indices.
Stock Market Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Stock Market Risk. Stock prices in general rise and fall as a result of investors’ perceptions of the market as a whole. If the stock market drops in value, the value of the Fund’s portfolio investments is also likely to decrease in value. The increase or decrease in the value of the Fund’s investments, in percentage terms, may be more or less than the increase or decrease in the value of the market. The value of securities in the Fund’s portfolio may decline due to daily fluctuations in the securities markets, including fluctuation in interest rates, national and international economic conditions and general equity market conditions. Local, regional, and global events such as war, acts of terrorism, the spread of infectious diseases or other public health issues, recessions, or other events could have a significant impact on the Fund’s investments.
Investment Style Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Investment Style Risk. The Fund pursues an income plus appreciation style of investing. This style of investing focuses on companies with stocks with generally larger market capitalizations. If the Adviser’s assessment of a company’s value or prospects for exceeding earnings expectations or market conditions is wrong, the Fund could suffer losses or produce poor performance relative to other funds. In addition, larger capitalization stocks sometimes tend to get overvalued during heightened periods of passive fund flows – in a manner that exceeds underlying real estate value.
Preferred Securities Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Preferred Securities Risk. Preferred securities combine features of both fixed income and equity. Preferred securities tend to exhibit characteristics more like traditional fixed income securities because regular income distributions are the principal source of return, as opposed to capital appreciation. Therefore, prices of preferred securities can rise or fall depending on interest rates. Adverse changes in the credit quality of the issuer may negatively impact the market value of the securities. This credit risk may also include that the issuer cannot afford to pay the preferred dividend due to tenant vacancies, defaults, or other cash flow issues. The securities may be redeemed beginning on their call date, or at any time following a special event (e.g., a change in tax law that adversely affects the Company with regard to the securities). If called, holders may face a reinvestment decision at lower future rates. Certain events can impact a preferred security issuer’s financial situation and ability to make timely payments to shareholders, including economic, political, legal, or regulatory changes and natural disasters. Event risk is unpredictable and can significantly impact preferred security holders since they are paid after bondholders. Also, in the event of a sale or privatization of a company, its preferred shares may be
negatively impacted. Preferred securities are also subject to duration risk as they are long-duration instruments, typically callable only at the option of the issuer. They are also subject to the risk that if the company is taken over by another company with higher leverage than the current issuer, coverages and other credit metrics could decline making the preferred security less valuable.
Convertible Securities Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Convertible Securities Risk. The market values of convertible securities are affected by market interest rates, the risk of issuer default on interest or principal payments and the value of the underlying common stock into which the convertible security may be converted. Additionally, a convertible security is subject to the same types of market and issuer risk as apply to underlying common stock. In addition, certain convertible securities are subject to involuntary conversions and may undergo principal write-downs upon the occurrence of certain triggering events, and, as a result, are subject to an increased risk of loss. Convertible securities may be rated below investment grade.
Restricted and Illiquid Securities Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Restricted and Illiquid Securities Risk. Certain securities generally trade in lower volume and may be less liquid than securities of large established companies. If a security is illiquid, the Adviser may not be able to sell the security at a time when it might wish to sell, which means that the Fund could lose money.
Debt Securities Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Debt Securities Risk. Debt securities are issued with a specific interest rate and maturity. Once the securities are issued, they are subject to credit risk and interest rate risk. Credit risk is the chance that the issuer will fail to pay the stipulated interest payments on the security, or to pay the principal at maturity. Negative perceptions of the issuer’s ability to make interest or principal payments will cause the price of the security to decline. While U.S. government-backed debt securities generally are considered to be among the highest credit quality, they are subject to market risk. The U.S. government guarantees the timely payment of interest and principal on U.S. Treasury securities but does not guarantee their price.
Interest Rate Risk1 Member  
Prospectus [Line Items]  
Risk [Text Block]
Interest Rate Risk. The value of common and preferred equities generally can be expected to fall when interest rates rise and to rise when interest rates fall. Interest rate risk is the risk that interest rates will rise, so that the value of the Fund's investments that are interest rate sensitive will fall. Because interest rate risk is the primary risk presented by bills, notes and bonds that are issued, sponsored, or guaranteed by the U.S. government, its agencies or instrumentalities ("U.S. Government Securities") and other very high-quality bonds, changes in interest rates may actually have a larger effect on the value of those bonds than on lower quality bonds. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. Interest rates may continue to rise in the future, possibly suddenly and significantly, with unpredictable effects
on the financial markets and the Fund’s investments. Fixed income instruments with longer durations are subject to more volatility than those with shorter durations.
Credit Risk1 Member  
Prospectus [Line Items]  
Risk [Text Block]
Credit Risk. Credit risk is the risk that a security in the Fund's portfolio will decline in price or the issuer will fail to make dividend, interest, or principal payments when due because the issuer of the security experiences a decline in its financial status. Real estate companies, including REITs, may be leveraged and financial covenants may affect the ability of REITs to operate effectively.
Concentration Risk Member  
Prospectus [Line Items]  
Risk [Text Block] Concentration Risk. The Fund will concentrate its investments in real estate companies and other publicly traded companies whose asset base is primarily real estate. As such, the Fund will be subject to risks similar to those associated with the direct ownership of real estate including those noted above under “Real Estate Market Risk and Related Risk.”
Covered Call Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Covered Call Risk. A covered call strategy involves the Fund writing (selling) covered call options in return for the receipt of premiums. The Fund, as the seller of the option, gives up the opportunity to benefit from value increases in the securities of the underlying security above the strike price of the sold call options, but continues to bear the risk of underlying security price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying equity price declines. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that Fund, as the option seller, is unable to sell options at a time that may be desirable or advantageous to do so.
Derivatives Risk Member  
Prospectus [Line Items]  
Risk [Text Block]
Derivatives Risk. The Fund may gain exposure to equity securities directly through investment in derivatives instruments, such as short covered call options. The Fund’s exposure to derivative instruments may involve risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index; and (iv) potential for a greater loss than the amount invested by the Fund.

•Call Options Risk. There are risks associated with the sale and purchase of call options. As the seller (writer) of a call option, the Fund may experience lower returns if the value of the reference index or security rises above the exercise price.
There is risk of loss to the Fund in connection with purchasing call options. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. The Fund retains the risk of loss should the price of such securities decline.
