Apr. 30, 2025
Active Trading Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Active trading market risk.  Active trading markets for fund shares may not be developed or maintained by market makers or authorized participants. Market makers are not obligated to make a market in the fund’s shares or to submit purchase or redemption orders for creation units. Decisions by market makers or authorized participants to reduce their role with respect to market making or creation/redemption activities in times of market stress could lead to wider bid-ask spreads and variances in the market of fund shares.
Authorized Participant Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Authorized participant concentration risk.  To the extent that authorized participants are unable or otherwise unavailable to proceed with creation and/or redemption orders and no other authorized participant is able to create or redeem in their place, shares may trade at a discount to net asset value (NAV) and may face delisting. To the extent that the fund’s limited number of intermediaries that act as authorized participants exit the business or are unable to proceed with creation and/or redemption orders and no other authorized participant is able to create or redeem in their place, there may be a significantly diminished trading market for fund shares.
Cash Transactions Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Cash transactions risk.  Under certain circumstances, the fund intends to effect some or all of its creation and redemption transactions using cash, rather than in-kind securities. As a result, an investment in the fund may be less tax-efficient than an investment in an ETF that effects all of its creation and redemption transactions in-kind. In order to obtain the cash needed to distribute redemption proceeds, the fund may be required to sell portfolio securities which may cause the fund to recognize capital gains or losses and incur higher brokerage costs. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover these costs and expenses, the fund’s NAV could be negatively impacted.
Changing Distribution Levels Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Changing distribution levels risk.  The fund may cease or reduce the level of its distribution if income or dividends paid from its investments declines.
Communication Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Communication sector risk.  Because the fund may be concentrated in securities of companies in the communication sector, any market price movements, regulatory or technological changes, or economic conditions affecting companies in the communication sector may have a significant impact on the fund’s performance.
Contingent Convertible Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Contingent convertible securities risk.  Contingent convertible securities have unique equity conversion or principal write-down features that involve additional risks, which may include cancellation of interest payments by the issuer or a regulatory authority; subordination to other creditors due to either a liquidation or other bankruptcy-related event or a conversion of the security from debt to equity; and a write-down of the security’s principal amount.
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.
Corporate Hybrid Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Corporate hybrid securities risk.  Although a corporate hybrid security may be considered an equity security within an issuer’s capital structure, a hybrid security may exhibit characteristics to a debt security, convertible security or other evidence of indebtedness on which the value of the interest, or principal of which, is determined by reference to changes in the value of a reference instrument or financial strength of a reference entity (e.g., a security or other financial instrument, asset, currency or interest rate). Hybrid securities may be functionally equivalent to preferred stock and are issued and trade in a manner similar to traditional perpetual preferred stock. Such hybrid securities may have a lower par amount, may allow the issuer to defer interest or dividend payments and may be equal to preferred shares or the lowest level of subordinated debt in terms of claims to an issuer’s assets in the event of liquidation. Also, the price of a hybrid security and any applicable reference instrument may not move in the same direction or at the same time.
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.
Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Currency risk.  Fluctuations in exchange rates may adversely affect the U.S. dollar value of a fund’s investments. Foreign currencies may decline in value, which could negatively impact 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. Securities the manager believes are undervalued may never realize their full potential value, and in certain markets value stocks may underperform the market as a whole.
ESG Integration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ESG integration risk.  The manager considers ESG factors that it deems relevant or additive, along with other material factors and analysis, when managing the fund. ESG factors may include, but are not limited to, matters regarding board diversity, climate change policies, and supply chain and human rights policies. The manager may consider these ESG factors on all or a meaningful portion of the fund’s investments. Incorporating ESG criteria and making investment decisions based on certain ESG characteristics, as determined by the manager, carries the risk that the fund may perform differently, including underperforming, funds that do not utilize ESG criteria, or funds that utilize different ESG criteria.
ETF Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ETF trading risk.  The market price of shares may include a bid-ask spread (the difference between the prices at which investors are willing to buy and sell shares), which may vary over time and may increase for various reasons, including decreased trading volume or reduced market liquidity.
Financial Services Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Financial services sector risk.  Financial services companies can be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors.
Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Fixed-income securities risk.  A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payments or repay all or any of the principal borrowed. Changes in a security’s credit quality may adversely affect fund performance.
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.
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: credit default swaps, foreign currency forward contracts, foreign currency swaps, futures contracts, interest-rate swaps, and options. 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.
Industry Or Sector Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Industry or sector investing risk.  The performance of a fund that focuses on a single industry or sector of the economy depends in large part on the performance of that industry or sector. As a result, the value of an investment may fluctuate more widely since it is more susceptible to market, economic, political, regulatory, and other conditions and risks affecting that industry or sector than a fund that invests more broadly across industries and sectors.
LIBOR Discontinuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] LIBOR discontinuation risk.  The official publication of the London Interbank Offered Rate (LIBOR), which many debt securities, derivatives and other financial instruments traditionally utilized as the reference or benchmark rate for interest rate calculations, was discontinued as of June 30, 2023. As of September 30, 2024, the UK FCA has confirmed that all publications of LIBOR, including all synthetic publications of the 1-, 3-, and 6-month U.S. dollar LIBOR settings, have ceased. The discontinuation of LIBOR and a transition to replacement rates may lead to volatility and illiquidity in markets and may adversely affect the fund’s performance.
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. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities. Periods of heavy redemption could cause the fund to sell assets at a loss or depressed value, which could negatively affect performance. Redemption risk is heightened during periods of declining or illiquid markets.
Lower Rated And High Yield Fixed Income Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Lower-rated and high-yield fixed-income securities risk.  Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.
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. To the extent the fund invests in non-cumulative preferred securities, whereby the issuer does not have an obligation to make up any arrearages to holders of such securities upon default, the amount of income earned by the fund may be adversely affected. With respect to depositary shares of preferred stock, the fund may only be entitled to a portion of the interest of a holder of preferred stock directly.
Premium Discount Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Premium/discount risk.  The NAV of the fund and the value of your investment may fluctuate. Disruptions to creations and redemptions or the market price of the fund’s holdings, the existence of extreme market volatility or potential lack of an active trading market for shares may result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares at a time when the market price is at a premium to the NAV or sells shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses. Given the nature of the relevant markets for certain of the fund’s securities, shares may trade at a larger premium or discount to the NAV than shares of other ETFs. In addition, in stressed market conditions, the market for shares may become less liquid in response to deteriorating liquidity in the markets for the fund’s underlying portfolio holdings. While the creation/redemption feature is designed to make it more likely that the fund’s shares normally will trade on stock exchanges at prices close to the fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the fund’s NAV due to timing reasons, supply and demand imbalances and other factors.
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.
Trading Issues Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Trading issues risk.  Trading in shares on NYSE Arca, Inc. (NYSE Arca) may be halted in certain circumstances. There can be no assurance that the requirements of NYSE Arca necessary to maintain the listing of the fund will continue to be met.
Trust Preferred Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Trust preferred securities risk.  Holders of trust preferred securities have limited voting rights to control the activities of the trust and no voting rights with respect to the financial institution. The market value of trust preferred securities may be more volatile than those of conventional debt securities. There can be no assurance as to the liquidity of trust preferred securities and the ability of holders, such as a fund, to sell their holdings. The condition of the financial institution is looked at to identify the risks of the trust preferred securities as the trust typically has no business operations other than to issue the trust preferred securities. If the financial institution defaults on interest payments to the trust, the trust will not be able to make dividend payments to holders of its securities, such as a fund.
Utilities Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Utilities sector risk.  Companies in the utilities sector may be affected by general economic conditions, supply and demand, financing and operating costs, rate caps, interest rates, liabilities arising from governmental or civil actions, consumer confidence and spending, competition, resource conservation and depletion, man-made or natural disasters, geopolitical events, and environmental and other government regulations.
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]  
Risk [Text Block] An investment in the fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
