Disciplined Value Emerging Markets Equity Trust Investment Risks - Disciplined Value Emerging Markets Equity Trust	Dec. 31, 2025
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.
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. 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.
Emerging Markets Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Emerging-market risk.  The risks of investing in foreign securities are magnified in emerging markets. Emerging-market countries may experience higher inflation, interest rates, and unemployment and greater social, economic, and political uncertainties than more developed countries.
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.
Exchange Traded Funds Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Exchange-traded fund (ETF) investment 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.
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. 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.
Greater China Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Greater China risk.  Investments in the Greater China region may be subject to less developed trading markets, acute political risks such as possible negative repercussions resulting from China’s relationship with Taiwan or Hong Kong, and restrictions on monetary repatriation or other adverse government actions. For example, a government may restrict investment in companies or industries considered important to national interests, intervene in contractual arrangements, or intervene in the financial markets, such as by imposing trading restrictions, or banning or curtailing short selling. A small number of companies and industries may generally represent a relatively large portion of the Greater China market as a whole.
Frontier Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Frontier-market risk.  Frontier-market countries generally have smaller economies and less-developed capital markets and political systems than traditional emerging-market countries, which magnifies emerging-market risks.
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, and 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.
Initial Public Offerings Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Initial public offerings (IPOs) risk.  IPO share prices are frequently volatile and may significantly impact fund performance.
Investment Company Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Investment company securities risk.  Fund shareholders indirectly bear their proportionate share of the expenses of any investment company in which the fund invests. The total return on such investments will be reduced by the operating expenses and fees of such other investment companies, including advisory fees.
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.
Master Limited Partnership Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Master limited partnership (MLP) risk.  MLPs generally reflect the risks associated with their underlying assets and with pooled investment vehicles. MLPs with credit-related holdings are subject to interest-rate risk and risk of default.
Preferred And Convertible Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Preferred and convertible securities risk.  Preferred stock dividends are payable only if declared by the issuer’s board. Preferred stock may be subject to redemption provisions. The market values of convertible securities tend to fall as interest rates rise and rise as interest rates fall. Convertible preferred stock’s value can depend heavily upon the underlying common stock’s value.
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.
Large Company Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Large company risk.  Larger companies may grow more slowly than smaller companies or be slower to respond to business developments. Large-capitalization securities may underperform the market as a whole.
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.
Quantitative Modeling Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Quantitative modeling risk.  Quantitative models may not accurately predict future market movements or characteristics, which may negatively impact performance. Models also may perform differently than expected due to implementation problems, technological malfunction, or programming or data inaccuracies, among other possible issues.
Sector Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Sector risk.  When a fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the fund were invested more evenly across sectors. To the extent that a fund invests in securities of companies in the financial services sector, the fund may be significantly affected by economic, market, and business developments, borrowing costs, interest-rate fluctuations, competition, and government regulation, among other factors, impacting that sector.
Securities Lending Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Securities lending risk.  Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral if the borrower fails financially. The fund could also lose money if the value of the collateral decreases.
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.
US Treasury Obligations Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	U.S. Treasury obligations risk.  The market value of direct obligations of the U.S. Treasury may vary due to changes in interest rates. In addition, changes to the financial condition or credit rating of the U.S. government may cause the value of the fund’s investments in obligations issued by the U.S. Treasury to decline.
Value Investment Style Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Value investment style risk.  Value securities, as a category, may underperform other segments of the market or the market as a whole and following a value-oriented investment strategy may cause the fund, at times, to underperform equity funds that employ a different investment style.
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]
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.
