Currency Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. securities, the value of dividends and interest earned from such securities, and gains and losses realized on the sale of such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Fund’s portfolio.
Cybersecurity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Cybersecurity Risk—Cybersecurity risk is the risk of an unauthorized breach and access to Fund assets, customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider, a financial intermediary or the issuers of securities held by the Fund to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Fund, its service providers or the issuers of securities held by the Fund may adversely impact the Fund or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Fund invests, which may cause the Fund’s investments to lose value.
Emerging Markets Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets or that are otherwise economically tied to emerging market countries. For example, these countries may have more unstable governments than developed countries and their economies may be based on only a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Fund’s ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Fund’s sub-adviser to evaluate local companies or their potential impact on the Fund’s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Fund are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.
Equity Security Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Equity Security Risk—Equity securities in the Fund’s portfolio may decline significantly in price over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular country, company, industry, or sector of the market. From time to time, the Fund may invest a significant portion of its assets in companies in one or more related sectors or industries which would make the Fund more vulnerable to adverse developments affecting such sectors or industries.
Financial Services Sector Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Financial Services Sector Risk—The Fund currently invests a significant portion of its assets in the financial services sector, although this may change over time. Financial services companies are particularly sensitive to the adverse effects of economic recession; changes in government regulation; the availability of capital; volatile interest rates; and the health of the commercial and residential real estate markets.
Foreign Investment Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Foreign Investment Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad, as well as armed conflicts and different legal, regulatory and tax environments. Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent the Fund invests a significant portion of its assets in the securities of companies in a single country or region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting that country or region. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards.
Large Cap Company Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Large-Cap Company Risk—Because it invests primarily in securities of large-capitalization companies, the Fund may underperform funds that invest primarily in securities of smaller capitalization companies during periods when the securities of such companies are in favor.
Market Risks [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Risk—The market value of the Fund’s investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time, due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact the value of the Fund’s investments whether or not the Fund invests in such country or region. Events such as war, the imposition or removal of tariffs, sanctions, and other trade restrictions, terrorism, geopolitical events, financial system instability, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may have a severe negative impact on the global economy, could cause financial markets to experience extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. Additionally, as inflation increases, the value of the Fund’s assets can decline.
Service Provider Operational Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Service Provider Operational Risk—The Fund’s service providers, such as the Fund’s administrator, custodian or transfer agent, may experience disruptions or operating errors that could negatively impact the Fund. Although service providers are required to have appropriate operational risk management policies and procedures, and to take appropriate precautions to avoid and mitigate risks that could lead to disruptions and operating errors, it may not be possible to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects.
Small and Mid Cap Company Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Small- and Mid-Cap Company Risk—Securities of small-cap companies involve substantial risk. Prices of small-cap securities may be subject to more abrupt or erratic movements, and to wider fluctuations and lower liquidity, than security prices of larger, more established companies or broader market averages in general. It may be difficult to sell small-cap securities at the desired time and price. While mid-cap securities may be slightly less volatile than small-cap securities, they still involve similar risks.
Value Stock Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Value Stock Risk—Value stocks are securities of companies that typically trade at a perceived discount to their intrinsic value and at valuation discounts relative to companies in the same industry. Value stocks often times are also in sectors that trade at a discount to the broader market. The reasons for their discount may vary greatly, but some examples may include adverse business, industry or other developments that may cause the company to be subject to special risks. The intrinsic value of a stock with value characteristics may be difficult to identify and may not be fully recognized by the market for a long time or a stock identified to be undervalued may actually be appropriately priced at a low level.
Active Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Active Management Risk—The Fund’s sub-adviser actively manages the Fund’s investments. Consequently, the Fund is subject to the risk that the investment techniques and risk analyses employed by the Fund’s sub-adviser, including its use of proprietary and third-party technology systems, models, algorithms and data management software, may not produce the desired results. This could cause the Fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.
Risk Lose Money [Member]

Risk [Text Block]	The value of your investment in this Fund will change daily. You could lose money by investing in the Fund.
