S000057734 [Member] Investment Risks - Morningstar Global Opportunistic Equity Fund
Apr. 30, 2025
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 judgments around allocating assets to subadvisers, open- and closed‑end investment companies, ETFs and individual securities 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 on a valuation basis, the Fund may favor asset classes or market segments that cause the Fund to underperform its benchmark. Given the wide latitude with which the adviser manages this portfolio, you should expect this Fund to periodically underperform broad markets.
Market Risk [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 or social unrest) may disrupt U.S. and world economies and can dramatically affect markets generally, certain industry sectors, and/or individual companies.
U S Government Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
U.S. Government Securities Risk—U.S. government obligations have different levels of credit support and, therefore, different degrees of credit risk. The U.S. government does not guarantee the market value of the securities it issues, so those values may fluctuate. Like most fixed-income securities, the prices of government
securities typically fall when interest rates increase and rise when interest rates decline. In addition, the payment obligations on certain securities in which the Fund may invest, including securities issued by certain U.S. Government agencies and U.S. Government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States.
Sovereign Debt Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Sovereign Debt Securities Risk—Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy, or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.
Mortgage Related and Other Asset Backed Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Mortgage-Related and Other Asset-Backed Securities Risk—Mortgage- and asset-backed securities represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust.
Mortgage- and asset-backed securities are subject to credit and interest rate risks, as well as extension and prepayment risks:
Extension Risk—Rising interest rates tend to extend the duration of mortgage-related securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, if the Fund holds mortgage-related securities, it may exhibit additional volatility.
Prepayment Risk—When interest rates decline, the value of mortgage-related securities with prepayment features may not increase as much as other fixed-income securities because borrowers may pay off their mortgages sooner than expected. In addition, the potential impact of prepayment on the price of asset-backed and mortgage-backed securities may be difficult to predict and result in greater volatility.
These securities also are subject to risk of default on the underlying mortgage or asset, particularly during periods of economic downturn. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities. TBA (or “to be announced”) commitments are forward agreements for the purchase or sale of securities, including mortgage-backed securities for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate and mortgage terms.
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.
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.
Investment Company 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.
REITs and Other Real Estate Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
REITs and Other Real Estate Companies Risk—REITs and other real estate company securities are subject to, among other risks: declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; changes in interest rates; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; or casualty or condemnation losses.
Interest Rate Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Interest-Rate Risk—The value of fixed-income securities, as well as some income-oriented equity securities that pay dividends, will typically decline when interest rates rise. The Fund may be subject to a greater risk of rising interest rates during low interest rate environments.
Call Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Call Risk—During periods of falling interest rates, an issuer may call or repay a higher-yielding fixed income security before its maturity date, forcing the Fund to reinvest in fixed income securities with lower interest rates than the original obligations.
Credit Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Credit Risk—Issuers of fixed-income securities could default or be downgraded if they fail to make required payments of principal or interest.
High Yield Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
High-Yield Risk—High-yield securities and unrated securities of similar credit quality (commonly known as junk bonds) are subject to greater levels of credit, valuation and liquidity risks. High-yield securities are considered speculative with respect to the issuer’s continuing ability to make principal and interest payments.
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.
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.
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.
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.
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.
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 the 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.
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.
