S000057728 [Member] Investment Risks - Morningstar International Equity Fund |
Apr. 30, 2026 |
|---|---|
| Active Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Management Risk—The Fund is actively managed with discretion and may underperform market indexes or other mutual funds with similar investment objectives. The Fund’s performance depends heavily on Morningstar’s skill and judgment in managing assets directly (through open- and closed-end investment companies, ETFs and individual securities) and allocating assets to subadvisers, and Morningstar and each subadviser’s skill in selecting securities and executing its strategy. The Fund could experience losses if these judgments prove to be incorrect.
|
| Asset Allocation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Asset Allocation Risk—In an attempt to invest in areas that look most attractive based on market, economic or other conditions, the Fund may favor asset classes or market segments that cause the Fund to underperform its benchmark.
|
| Market Risks [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk—The value of stocks and other securities can be highly volatile and prices may fluctuate widely, which means you should expect a wide range of returns and could lose money, even over a long time period. Various economic, industry, regulatory, political or other factors (such as natural disasters, epidemics and pandemics, war, terrorism, changes in trade regulation or economic sanctions, conflicts, social unrest, recessions, or the threat or occurrence of a government shutdown) may disrupt U.S. and world economies and can dramatically affect markets generally, certain industry sectors, and/or individual companies.
|
| Smaller Companies Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Smaller Companies Risk—The stocks of small- or mid‑sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources, and their securities may trade less frequently and in lower volume than the securities of larger companies, which could lead to higher transaction costs.
|
| Sector Focus Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Focus Risk—The Fund may from time to time have a significant amount of its assets invested in one market sector or group of related industries. To the extent that the Fund focuses on particular sectors, groups of industries or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of industries, sectors or investments. Information about the Fund’s investment in a particular industry or market sector is available in its annual and semi-annual reports to shareholders, on the Fund’s website and/or on the Fund’s Forms N‑PORT and N‑CSR.
|
| Quantitative Models Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Quantitative Models Risk—Morningstar may utilize quantitative models in managing all or a portion of the Fund. Such quantitative models may not perform as expected and may cause the Fund to underperform other investment strategies that do not use quantitative models. Flaws or errors in the quantitative model’s assumptions, design, execution, or data inputs may adversely affect Fund performance. Due to the significant role technology plays in a quantitative model, use of a quantitative model carries the risk of potential issues with the design, coding, implementation, or maintenance of the technology used in the quantitative model. Quantitative models may underperform in certain market environments including in stressed or volatile market conditions. There can be no assurance that the use of quantitative models by Morningstar will enable the Fund to achieve its objective.
|
| Foreign Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Securities Risk—Securities of non‑U.S. issuers may be less liquid, more volatile, and harder to value than U.S. securities. They may also be subject to political, economic and regulatory risks, and market instability. Non‑U.S. issuers also may not be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable and publicly available financial and other information about such issuers, as compared to U.S. issuers.
|
| Currency Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Currency Risk—Because this Fund may invest in securities of non‑U.S. issuers, changes in currency exchange rates (including in the markets in which such non‑U.S. issuers’ securities are traded) could hurt performance. Morningstar or a subadviser may decide not to hedge, or may not be successful in hedging, its currency exposure.
|
| Derivatives Risks [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk—A derivative is an instrument with a value based on the performance of an underlying currency, security, index, or other reference asset. Derivatives involve risks different from, or possibly greater than, the risks of investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, or difficult to value. In addition, derivatives could cause losses if the counterparty to the transaction does not perform as promised. The investment results achieved by using derivatives may not match or fully offset changes in the value of the underlying currency, security, index, or other reference asset that the Fund was attempting to hedge or the investment opportunity it was trying to pursue. Derivatives also are susceptible to operational risks, such as system failures and inadequate controls, and legal risks, such as insufficient documentation and lack of enforceability of a contract.
|
| ETF Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment Company/ETF Risk—An investment company, including an open- or closed-end mutual fund or ETF, in which the Fund invests may not achieve its investment objective or execute its investment strategies effectively, or a large purchase or redemption activity by shareholders might negatively affect the value of the shares. The Fund must also pay its pro rata portion of an investment company’s fees and expenses. Shares of ETFs trade on exchanges and may be bought and sold at market value. ETF shares may be thinly traded, making it difficult for the Fund to sell shares at a particular time or an anticipated price. ETF shares may also trade at a premium or discount to the net asset value of the ETF; at times, this premium or discount could be significant.
|
| Valuation risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation risk—The amount the Fund actually receives when selling (or otherwise disposing of) an investment may differ from the Fund’s recorded valuation of that investment. This discrepancy is more likely for investments that trade infrequently, are valued using fair-value methods or third-party pricing vendors, or are held during periods of market stress or heightened volatility. Consequently, the Fund may realize a larger loss or a smaller gain than anticipated based on its stated valuation. Additionally, the Fund’s valuation process could be disrupted by technology failures or errors originating from pricing vendors or other external service providers.
|
| Cybersecurity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk—The Fund, like all companies, may be susceptible to operational and information security risks. Cybersecurity failures or breaches of the Fund or its service providers or the issuers of securities in which a Fund invests, have the ability to cause disruptions and impact business operations, and the Fund and its shareholders could be negatively impacted as a result.
|
| European Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | European Market Risk—Adverse economic and political events in Europe may cause the Fund’s investments to decline in value. Member states of the European Union (“EU”) are subject to restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, recessions in an EU member country, the departure of a member state from the EU, and war in or around the European region may have a significant adverse effect on the economies of other EU member countries.
|
| Asian Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Asian Market Risk—Investments in securities of Asian issuers involve risks and special considerations not typically associated with investments in the U.S. securities markets. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, rapid fluctuations in inflation and interest rates, decreased exports, economic recessions and political unrest. Economic and political events in any one Asian country can have a significant effect on the entire Asian region as well as on major trading partners outside Asia, and any adverse effect on some or all of the Asian countries and regions in which the Fund invests. The securities markets in some Asian economies are relatively underdeveloped and may subject the Fund to a higher degree of risk.
|
| China Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | China Market Risk—To the extent the Fund invests in securities of companies located in or operating in China, those companies may be subject to decisions made by the Chinese government including through monetary policy and currency exchange rates. Heightened trade tensions or political disputes may disrupt supply chains or adversely impact revenues of companies selling to or within China. Actions outside of the Fund’s control may result in the Fund’s inability to buy/sell securities listed on Chinese exchanges.
|
| Japan Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Japan Market Risk—To the extent the Fund invests in securities of companies located in or operating in Japan, those companies may be subject to considerable degrees of economic, political and social instability, which could negatively impact Japanese issuers. In recent times, Japan’s economic growth rate has remained low, and it may remain low in the future. In addition, Japan is subject to the risk of natural disasters, such as earthquakes, volcanic eruptions, typhoons and tsunamis, which could negatively affect the securities of Japanese companies held by the Fund. Japan’s relations with its neighbors have at times been strained, and strained relations with its neighbors or trading partners may cause uncertainty in the Japanese markets and adversely affect the overall Japanese economy.
|
| Geographic Concentration Risks [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Geographic Concentration Risk—To the extent that the Fund invests a significant portion of its assets in a particular country, region or continent, economic, political, social and environmental conditions in such country, region or continent will have a greater effect on the Fund’s performance than they would in a more geographically diversified equity fund. Information about the Fund’s investment in a geographic area is available in its annual and semi-annual reports to shareholders, on the Fund’s website and/or on the Fund’s Forms N‑PORT and N‑CSR.
|
| Cash Cash Equivalents Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cash/Cash Equivalents Risk—In rising markets, holding cash or cash equivalents will negatively affect the Fund’s performance relative to its benchmark.
|
| Private Placements Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Private Placements Risk—Securities that are purchased in private placements are subject to restrictions on resale as a matter of contract or under federal securities laws. Because there may be relatively few potential purchasers for these investments, especially under adverse circumstances, a Fund could find it more difficult to sell private placements at an advisable time or attractive price. Additionally, such securities may not be listed on an exchange and may have no active trading market. Accordingly, many private placement securities may be illiquid. At times, it may also be more difficult to determine the fair value of such securities for purposes of computing a Fund’s net asset value.
|
| Emerging Markets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging-Markets Risk—Emerging-market countries may have relatively unstable governments and economies based on only a few industries, which can cause greater instability. These countries are also more likely to experience higher levels of inflation, deflation, or currency devaluations, which could hurt their economies and securities markets.
|
| Multimanager and Subadviser Selection Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Multimanager and Subadviser Selection Risk—To a significant extent, the Fund’s performance depends on Morningstar’s skill in selecting subadvisers and each subadviser’s skill in selecting securities and executing its strategy. Subadviser strategies may occasionally be out of favor and subadvisers may underperform relative to their peers or benchmarks.
|
| Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | You can lose money by investing in the Fund. |
