Cash And Cash Equivalents Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Cash and cash equivalents risk. Under certain market conditions, such as during a rising stock market, rising interest rate or rising credit spread markets, the use of cash and/or cash equivalents, including money market instruments, could have a negative effect on the fund’s ability to achieve its investment objective and may negatively impact the fund’s performance.
Convertible Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Convertible securities risk. Convertible securities are subject to certain risks of both equity and debt securities. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. As the market price of underlying common stock declines below the conversion price, the market value of the convertible security tends to be increasingly influenced by its yield.
Credit And Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit and counterparty risk. The issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter derivatives contract, or a borrower of fund securities may not make timely payments or otherwise honor its obligations. U.S. government securities are subject to varying degrees of credit risk depending upon the nature of their support. A downgrade or default affecting any of the fund’s securities could affect the fund’s performance.
Economic And Market Events Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Banks and financial services companies could suffer losses if interest rates rise or economic conditions deteriorate.
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Equity securities risk. The price of equity securities may decline due to changes in a company’s financial condition or overall market conditions.
Exchange Traded Funds Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Exchange-traded funds (ETFs) risk. The risks of owning shares of an ETF include the risks of owning the underlying securities the ETF holds. Lack of liquidity in an ETF could result in the ETF being more volatile than its underlying securities. An ETF’s shares could trade at a significant premium or discount to its net asset value (NAV). A fund bears ETF fees and expenses indirectly.
Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign securities risk. Less information may be publicly available regarding foreign issuers, including foreign government issuers. Foreign securities may be subject to foreign taxes and may be more volatile than U.S. securities. Currency fluctuations and political and economic developments may adversely impact the value of foreign securities. The risks of investing in foreign securities are magnified in emerging markets. Depositary receipts are subject to most of the risks associated with investing in foreign securities directly because the value of a depositary receipt is dependent upon the market price of the underlying foreign equity security. Depositary receipts are also subject to liquidity risk.
Hong Kong Stock Connect Program (Stock Connect) Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Hong Kong Stock Connect Program (Stock Connect) risk. Trading in China A-Shares through Stock Connect, a mutual market access program that enables foreign investment in the People’s Republic of China (PRC), is subject to certain restrictions and risks. Securities listed on Stock Connect may lose purchase eligibility, which could adversely affect the fund’s performance. Trading through Stock Connect is subject to trading, clearance, and settlement procedures that may continue to develop as the program matures. Any changes in laws, regulations and policies applicable to Stock Connect may affect China A-Share prices. These risks are heightened by the underdeveloped state of the PRC’s investment and banking systems in general.
Hedging Derivatives And Other Strategic Transactions Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Hedging, derivatives, and other strategic transactions risk. Hedging, derivatives, and other strategic transactions may increase a fund’s volatility and could produce disproportionate losses, potentially more than the fund’s principal investment. Risks of these transactions are different from and possibly greater than risks of investing directly in securities and other traditional instruments. Under certain market conditions, derivatives could become harder to value or sell and may become subject to liquidity risk (i.e., the inability to enter into closing transactions). Derivatives and other strategic transactions that the fund intends to utilize include: foreign currency forward contracts, futures contracts, options, swaps, and total return swaps. Foreign currency forward contracts, futures contracts, options, and swaps generally are subject to counterparty risk. In addition, swaps may be subject to interest-rate and settlement risk, and the risk of default of the underlying reference obligation. Derivatives associated with foreign currency transactions are subject to currency risk.
High Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] High portfolio turnover risk. Trading securities actively and frequently can increase transaction costs (thus lowering performance) and taxable distributions.
Illiquid And Restricted Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Illiquid and restricted securities risk. Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security’s market price and the fund’s ability to sell the security.
Leveraging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Leveraging risk. Using derivatives may result in a leveraged portfolio. Leveraging long exposures increases a fund’s losses when the value of its investments declines. Some derivatives have the potential for unlimited loss, regardless of the size of the initial investment.
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Liquidity risk. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments.
Operational And Cybersecurity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Operational and cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund’s securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.
Preferred Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Preferred stock risk. Preferred stock generally ranks senior to common stock with respect to dividends and liquidation but ranks junior to debt securities. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock may be subject to optional or mandatory redemption provisions.
Real Estate Investment Trust Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Real estate investment trust (REIT) risk. REITs, pooled investment vehicles that typically invest in real estate directly or in loans collateralized by real estate, carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.
Short Sales Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Short sales risk. In a short sale, a fund pays interest on a borrowed security. The fund will lose money if the price of the borrowed security increases between the short sale and the replacement date.
Small And Mid Sized Company Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Small and mid-sized company risk. Small and mid-sized companies are generally less established and may be more volatile than larger companies. Small and/or mid-capitalization securities may underperform the market as a whole.
Synthetic Short Exposure Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Synthetic short exposure risk. The fund will gain synthetic short exposure through a forward commitment through a swap agreement. Synthetic short exposures involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment.
Unseasoned Issuers Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Unseasoned issuers risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.
Value Investment Style Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Value investment style risk. Value securities may underperform the market as a whole, which may cause value-oriented funds to underperform equity funds with other investment strategies. Securities the manager believes are undervalued may never perform as expected.
Warrants Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Warrants risk. The prices of warrants may not precisely reflect the prices of their underlying securities. Warrant holders do not receive dividends or have voting or credit rights. A warrant ceases to have value if not exercised prior to its expiration date.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] Many factors affect performance, and fund shares will fluctuate in price, meaning you could lose money.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]
