MARKET RISKS [Member]  
Prospectus [Line Items]  
Risk [Text Block]
MARKET RISK is the risk that the value of the Fund’s investments may increase or decrease in response to expected, real or perceived economic, political or financial events in the U.S. or global markets. The frequency and magnitude of such changes in value cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in response to changing market conditions, inflation, elevated levels of government debt, changes in interest rates, lack of liquidity in the bond or equity markets or volatility in the equity markets. Market disruptions caused by local or regional events such as financial institution failures, changes in trade regulation or economic sanctions, internal unrest and discord, war, acts of terrorism, the spread of infectious illness (including epidemics and pandemics) or other public health issues, recessions, the threat or occurrence of a government shutdown or other events or adverse investor sentiment could have a significant impact on the Fund and its investments. During periods of market disruption or other abnormal market conditions, the Fund’s exposure to risks described elsewhere in this summary will likely increase.
QUALITY FACTOR RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
QUALITY FACTOR RISK is the risk that the past performance of companies that have exhibited quality characteristics does not continue or the returns on securities issued by such companies may be less than returns from other styles of investing or the overall stock market. There may be periods when quality investing is out of favor and during which time the Fund’s performance may suffer.
SECTOR RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
SECTOR RISK is the risk that companies in similar businesses may be similarly affected by particular economic or market events, which may, in certain circumstances, cause the value of securities of all companies in a particular sector of the market to decrease.
  ∎  
INFORMATION TECHNOLOGY SECTOR RISK is the risk that securities of technology companies may be subject to greater price volatility than securities of companies in other sectors. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology companies also may be affected adversely by changes in technology, consumer and business purchasing patterns, government scrutiny or regulation, legal action and/or obsolete products or services.
PREFERRED SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
PREFERRED SECURITIES RISK is the risk that preferred securities may be subordinated to bonds or other debt instruments, subjecting them to a greater risk of non‑payment, may be less liquid than many other securities, such as common stocks, and generally offer no voting rights with respect to the issuer. Preferred securities also are subject to issuer-specific and market risks applicable generally to equity securities.
DIVIDEND RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
DIVIDEND RISK is the risk that as a group, securities that pay high dividends may fall out of favor with investors and underperform companies that do not pay high dividends. Also,
changes in the dividend policies of such companies and the capital resources available for such companies’ dividend payments may affect the Fund. There is the possibility that dividend-paying companies could reduce or eliminate the payment of dividends in the future or an anticipated acceleration of dividends may not occur. Depending on market conditions, dividend paying stocks that meet the Fund’s investment criteria may not be widely available for purchase by the Fund, which may increase the volatility of the Fund’s returns and limit its ability to produce current income while remaining fully diversified. High-dividend stocks may not experience high earnings growth or capital appreciation. The Fund’s performance during a broad market advance could suffer because dividend paying stocks may not experience the same capital appreciation as non‑dividend paying stocks.
SECURITIES LENDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
SECURITIES LENDING RISK is the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral.
AUTHORIZED PARTICIPANT CONCENTRATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
AUTHORIZED PARTICIPANT CONCENTRATION RISK is the risk that the Fund may be adversely affected because it has a limited number of institutions that act as authorized participants (“Authorized Participants”). Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. To the extent that these institutions exit the business or are unable or unwilling to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able or willing to step forward to create or redeem Creation Units (as defined below), Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting.
MARKET TRADING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]
MARKET TRADING RISK is the risk that the Fund faces because its shares are listed on a securities exchange, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.
Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of its listing exchange, make trading in the shares inadvisable. The market prices of Fund shares will generally fluctuate in accordance with changes in its NAV, changes in the relative supply of, and demand for, Fund shares, and changes in the liquidity, or the perceived liquidity, of the Fund’s holdings.
DERIVATIVES RISKS [Member]  
Prospectus [Line Items]  
Risk [Text Block]
DERIVATIVES RISK is the risk that derivatives may pose risks in addition to and greater than those associated with investing directly in securities, currencies and other instruments, may be illiquid or less liquid, more volatile, more difficult to value and leveraged so that small changes in the value of the underlying instrument may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party to the transaction will not perform its contractual obligations. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.
  ∎  
FUTURES CONTRACTS RISK is the risk that there will be imperfect correlation between the change in market value of the Fund’s securities and the price of futures contracts, which may result in the strategy not working as intended; the possible inability of the Fund to sell or close out a futures contract at the desired time or price; losses due to unanticipated market movements, which potentially are unlimited; and the possible inability of the Fund’s investment adviser to correctly predict the direction of securities’ prices, interest rates, currency exchange rates and other economic factors, which may make the Fund’s returns more volatile or increase the risk of loss.
Risk Lose Money [Member]  
Prospectus [Line Items]

Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]
