| Small-Capitalization Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small-Capitalization Companies Risk. Investing in securities of small-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Small-capitalization companies often have less predictable earnings, more limited product lines, markets, distribution channels and financial resources, and the management of such companies may be dependent upon one or a small number of individuals. Price movements of small-capitalization companies may be more volatile than mid-capitalization and large-capitalization companies.

| Market Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic, political, or geopolitical conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. In addition, local, regional or global events such as war, acts of terrorism, international conflicts, trade disputes, supply chain disruptions, cybersecurity events, the spread of infectious illness or other public health issues, natural disasters or climate events, or other events could have a significant impact on a security or instrument.
|
| Equity Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests.
|
| Value-Oriented Investment Strategy Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Value-Oriented Investment Strategy Risk. Value stocks are those that are believed to be undervalued in comparison to their peers due to adverse business developments, unfavorable market sentiment, or other factors. Value investing is subject to the risk that the market will not recognize a security’s inherent value for a long time or at all or that a stock judged to be undervalued may actually be appropriately priced or overvalued. In addition, during some periods (which may be extensive) value stocks generally may be out of favor in the markets.
|
| Quantitative Security Selection Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Quantitative Security Selection Risk. Data for some companies may be less available and/or less current than data for companies in other markets. The Sub-Adviser uses quantitative analysis, and its processes could be adversely affected if erroneous or outdated data is utilized. In addition, securities selected using quantitative analysis could perform differently from the financial markets as a whole as a result of the characteristics used in the analysis, the weight placed on each characteristic and changes in the characteristic’s historical trends.
|
| Sector Focus Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Focus Risk. The Fund may invest a larger portion of its assets in one or more sectors and thus will be more susceptible to negative events affecting those sectors. •Consumer Discretionary Sector Risk. The Fund is expected to have exposure to companies in the consumer discretionary sector, and therefore, the Fund’s performance could be negatively impacted by events affecting this sector. The consumer discretionary sector includes, for example, automobile, textile and retail companies. This sector can be significantly affected by, among other things, changes in domestic and international economies, exchange and interest rates, economic growth, worldwide demand, supply chain constraints and social trends. Success of companies in the consumer discretionary sector also depends heavily on disposable household income and consumer spending, which can be negatively impacted by inflationary pressures on consumers. •Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be affected by supply and demand both for their specific products or services and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. •Energy Sector Risk. The market value of securities in the energy sector may decline for many reasons including, fluctuations in energy prices and supply and demand of energy fuels caused by geopolitical events, the success of exploration projects, weather or meteorological events, taxes, increased governmental or environmental regulation, resource depletion, rising interest rates, declines in domestic or foreign production, accidents or catastrophic events that result in injury, loss of life or property, pollution or other environmental damage claims, terrorist threats or attacks, among other factors. Markets for various energy-related commodities can have significant volatility and are subject to control or manipulation by large producers or purchasers. Companies in the energy sector may need to make substantial expenditures, and may incur significant amounts of debt, to maintain or expand their reserves through exploration of new sources of supply, through the development of existing sources, through acquisitions, or through long-term contracts to acquire reserves. Factors adversely affecting producers, refiners, distributors, or others in the energy sector may adversely affect companies that service or supply those entities, either because demand for those services or products is curtailed, or those services or products come under price pressure. Issuers in the energy sector may also be impacted by changing investor and consumer preferences arising from the sector’s potential exposure to sustainability and environmental concerns.

| Foreign Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investment Risk. The prices of foreign securities may be more volatile than the prices of securities of U.S. issuers because of economic and social conditions abroad, political developments, and changes in the regulatory environments of foreign countries. Changes in exchange rates and interest rates and the imposition of sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the U.S. and/or other governments may adversely affect the values of the Fund’s foreign investments. Foreign companies are generally subject to different legal and accounting standards than U.S. companies, and foreign financial intermediaries may be subject to less supervision and regulation than U.S. financial firms. Foreign securities include ADRs. Unsponsored ADRs involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends. Emerging markets tend to be more volatile than the markets of more mature economies and generally have less diverse and less mature economic structures and less stable political systems than those of developed countries.
|
| Currency Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Currency Risk. The values of investments in securities denominated in foreign currencies increase or decrease as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile and are affected by factors such as general economic conditions, the actions of the United States and foreign governments or central banks, the imposition of currency controls, and speculation. |
| Management And Strategy Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Management and Strategy Risk. The value of your investment depends on the judgment of the Sub-Adviser about the quality, relative yield, value, or market trends affecting a particular security, industry, sector, or region, which may prove to be incorrect. |
| ETF Risks Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | ETF Risks. •Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. •Premium-Discount Risk. The Shares may trade above or below their net asset value (“NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on NYSE Arca, Inc (the “Exchange”) or other securities exchanges. The trading price of Shares may deviate significantly from NAV during periods of market volatility or limited trading activity in Shares. In addition, you may incur the cost of the “spread,” that is, any difference between the bid price and the ask price of the Shares. In addition, because securities held by the Fund may trade on foreign exchanges that are closed when its primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs. •Cost of Trading Risk. Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. •Trading Risk. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of its underlying portfolio holdings, which can be less liquid than Shares, potentially causing the market price of Shares to deviate from its NAV. The spread varies over time for Shares of the Fund based on the Fund’s trading volume and market liquidity and is generally lower if the Fund has high trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity (which is often the case for funds that are newly launched or small in size).

| 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 FDIC or any government agency. |
| Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. The Fund is classified as “non-diversified,” which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. Investment in securities of a limited number of issuers exposes the Fund to greater volatility and potential losses than if its assets were diversified among the securities of a greater number of issuers.
