The Fund will invest to a significant extent in the securities of Real Estate Companies that have small to mid-sized capitalizations. Real Estate Companies, which also include master limited partnerships, are primarily engaged in the ownership, construction, management, financing or sale of residential, commercial or industrial real estate. Real Estate Companies also may include companies whose products and services are related to the real estate industry, such as building supply manufacturers, mortgage lenders, or mortgage servicing companies. The Fund also may purchase American Depositary Receipts (ADRs) to gain exposure to foreign Real Estate Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the real estate sector and, therefore, may be concentrated in an industry or group of industries within the real estate sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including: Active Trading RiskActive trading, also called high portfolio turnover, may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance. High portfolio turnover may also result in high levels of short-term capital gains, which are generally taxable as ordinary income when distributed to shareholders. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Funds ability to achieve its investment objective. Depositary Receipt RiskThe Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs in the Funds portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Funds portfolio. In addition, the value of the securities underlying the ADRs may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers. Derivatives RiskThe Funds investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Funds other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested. Early Closing RiskThe Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Funds inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses. Equity RiskThe Fund is subject to the risk that the value of the equity securities or equity-based derivatives in the Funds portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure. Foreign Issuer Exposure RiskThe Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets. Industry and Real Estate Sector RiskThe risk of concentrating Fund investments in a limited number of issuers conducting business in the same industry or group of industries is that the Fund will be more susceptible to the risks associated with that industry or group of industries than a fund that does not concentrate its investments. To the extent that the Funds investments are exposed to issuers conducting business in the real estate sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Real Estate Companies also may fluctuate widely in response to such events. Market RiskThe Funds investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Funds value, to fluctuate over time. An investment in the Fund may lose money. Mid-Capitalization Securities RiskThe Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Non-Diversification RiskThe Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund. Small-Capitalization Securities RiskThe Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Temporary Defensive Investment RiskThe Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets. Trading Halt RiskIf a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Funds ability to use leverage and may prevent the Fund from achieving its investment objective.falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph
