Risk Table - Virtus Emerging Markets Opportunities Fund	Risk [Text Block]
Principal Risks	Principal Risks The fund may not achieve its objective(s), and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The principal risks of investing in the fund are identified below (in alphabetical order after the first eight risks).
Risk Lose Money [Member]	If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money.
Market Volatility Risk	> Market Volatility Risk: The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g., Russia’s invasion of Ukraine), geopolitical risk, acts of terrorism, the spread of infectious illness or other public health issue, recessions, tariffs and other restrictions on trade, or the threat or potential of one or more such events and developments, could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended.
Issuer Risk	> Issuer Risk: The fund will be affected by factors specific to the issuers of securities and other instruments in which the fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers.
Equity Securities Risk	> Equity Securities Risk: The value of the stocks held by the fund may be negatively affected by the financial market, industries in which the fund invests, or issuer-specific events. Focus on a particular style or in small or medium-sized companies may enhance that risk.
Foreign Investing Risk	> Foreign Investing Risk: Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; less publicly available information about the foreign investment; and political, regulatory, economic, and market risk.
Emerging Market Risk	> Emerging Market Risk: Emerging markets securities may be more volatile, or more greatly affected by negative conditions, than those of their counterparts in more established foreign markets. Such securities may also be subject to Sanctions Risk.
Investing in China Risk	> Investing in China Risk: The government of China maintains strict currency controls in order to achieve economic, trade and political objectives and regularly intervenes in the currency market. The Chinese government also plays a major role in the country’s economic policies regarding foreign investments. Foreign investors are subject to the risk of loss from expropriation or nationalization of their investment assets and property, governmental restrictions on foreign investments and the repatriation of capital invested. In addition, the rapid growth rate of the Chinese economy over the past several years may not continue, and the trend toward economic liberalization and disparities in wealth may result in social disorder, including violence and labor unrest. These and other factors could have a negative impact on the fund’s performance and increase the volatility of an investment in the fund. Certain securities issued by companies located or operating in China, such as China A-shares, are also subject to trading restrictions, quota limitations and less market liquidity, which could pose risks to the fund.
Sanctions Risk	> Sanctions Risk: The imposition of sanctions and other similar measures could cause a decline in the value and/or liquidity of securities issued by or tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent the fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of transactions, and negatively impact the fund’s liquidity and performance.
Focused Investment Risk	> Focused Investment Risk: To the extent the fund focuses its investments on a limited number of issuers, sectors, industries, geographic regions or portfolio themes, it may be subject to increased risk and volatility.
Small and Medium Market Capitalization Companies Risk	> Small and Medium Market Capitalization Companies Risk: The fund’s investments in small and medium market capitalization companies may increase the volatility and risk of loss to the fund, as compared with investments in larger, more established companies.
Counterparty Risk	> Counterparty Risk: There is risk that a party upon whom the fund relies to complete a transaction will default.
Credit Risk	> Credit Risk: If the issuer of a debt instrument fails to pay interest or principal in a timely manner, or negative perceptions exist in the market of the issuer’s ability to make such payments, the price of the security may decline.
Currency Rate Risk	> Currency Rate Risk: Fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect the value of the fund’s shares.
Depositary Receipts Risk	> Depositary Receipts Risk: Investments in foreign companies through depositary receipts may expose the fund to the same risks as direct investments in securities of foreign issuers.
Derivatives Risk	> Derivatives Risk: Derivatives and other similar instruments (collectively referred to in this section as “derivatives”) may include, among other things, futures, options, forwards, and swap agreements, and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment.
Leverage Risk	> Leverage Risk: When the fund leverages its portfolio by borrowing or by engaging in certain types of transactions or instruments, including derivatives, the fund may be less liquid, may liquidate positions at an unfavorable time, and the volatility of the fund’s value may increase.
Liquidity Risk	> Liquidity Risk: Certain instruments may be difficult or impossible to sell at a time and price beneficial to the fund.
Portfolio Turnover Risk	> Portfolio Turnover Risk: The fund’s principal investment strategies may result in a high portfolio turnover rate. See the “Portfolio Turnover” section above for more information about the impact that portfolio turnover can have on your investment.
Preferred Stocks Risk	> Preferred Stocks Risk: Preferred stocks may decline in price, fail to pay dividends when expected, or be illiquid.
Redemption Risk	> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of fund shares would particularly impact non-redeeming shareholders who do not hold their fund shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund’s net asset value and liquidity. In addition, a large redemption could result in the fund’s current expenses being allocated over a smaller asset base, leading to an increase in the fund’s expense ratio. Please see “More Information About Risks of Investing in the Funds” in the fund’s prospectus for a more detailed description of the fund’s risks.

The principal risks of investing in the fund are identified below (in alphabetical order after the first nine risks).
Risk Lose Money [Member]	If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money.
Market Volatility Risk	> Market Volatility Risk: The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g., Russia’s invasion of Ukraine), geopolitical risk, acts of terrorism, the spread of infectious illness or other public health issue, recessions, tariffs and other restrictions on trade, or the threat or potential of one or more such events and developments, could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended.
Issuer Risk	> Issuer Risk: The fund will be affected by factors specific to the issuers of securities and other instruments in which the fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers.
High-Yield/High-Risk Fixed Income Securities (Junk Bonds) Risk	> High-Yield/High-Risk Fixed Income Securities (Junk Bonds) Risk: There is a greater risk of issuer default, less liquidity, and increased price volatility related to high-yield/high-risk securities than investment grade securities, and high-yield/high-risk securities are generally considered to be speculative.
Bank Loan Risk	> Bank Loan Risk: In addition to the risks typically associated with high-yield/high-risk fixed income securities, bank loans may be unsecured or not fully collateralized, may be subject to restrictions on resale, may be less liquid and may trade infrequently on the secondary market. Bank loans settle on a delayed basis; thus, sale proceeds may not be available to meet redemptions for a substantial period of time after the sale of the loan.
Equity Securities Risk	> Equity Securities Risk: The value of the stocks held by the fund may be negatively affected by the financial market, industries in which the fund invests, or issuer-specific events. Focus on a particular style or in small or medium-sized companies may enhance that risk.
Credit Ratings and Unrated Securities Risk	> Credit Ratings and Unrated Securities Risk: If a subadviser is unable to accurately assess the quality of an unrated fixed income security or the credit rating assigned by a rating agency does not reflect an issuer’s current financial condition or credit quality, the fund may invest in a security with greater risk than intended, or the securities may be more difficult to sell than anticipated.
Debt Instruments Risk	> Debt Instruments Risk: Debt instruments are subject to greater levels of credit and liquidity risk, may be speculative and may decline in value due to changes in interest rates or an issuer’s or counterparty’s deterioration or default.
Derivatives Risk	> Derivatives Risk: Derivatives and other similar instruments (collectively referred to in this section as “derivatives”) may include, among other things, futures, options, forwards, and swap agreements, and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment.
Convertible Securities Risk	> Convertible Securities Risk: The value of a convertible security may decline as interest rates rise and/or vary with fluctuations in the market value of the underlying securities. The security may be called for redemption at a time and/or price unfavorable to the fund.
Allocation Risk	> Allocation Risk: If the fund’s exposure to equities and fixed income securities, or to other asset classes, deviates from the intended allocation, or if the fund’s allocation is not optimal for market conditions at a given time, the fund’s performance may suffer.
Contingent Convertible Securities Risk	> Contingent Convertible Securities Risk: Contingent convertible securities (“CoCos”) are subject to greater levels of credit and liquidity risk than fixed income securities generally. They may rank junior to other creditors in the event of a liquidation or other bankruptcy-related event and become further subordinated as a result of conversion from debt to equity.
Counterparty Risk	> Counterparty Risk: There is risk that a party upon whom the fund relies to complete a transaction will default.
Covenant Lite Loans Risk	> Covenant Lite Loans Risk: The lack of financial maintenance covenants in covenant lite loans increases the risk that the fund will experience difficulty or delays in enforcing its rights on its holdings of such loans, which may result in losses, especially during a downturn in the credit cycle.
Credit Risk	> Credit Risk: If the issuer of a debt instrument fails to pay interest or principal in a timely manner, or negative perceptions exist in the market of the issuer’s ability to make such payments, the price of the security may decline.
Currency Rate Risk	> Currency Rate Risk: Fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect the value of the fund’s shares.
Depositary Receipts Risk	> Depositary Receipts Risk: Investments in foreign companies through depositary receipts may expose the fund to the same risks as direct investments in securities of foreign issuers.
Emerging Market Risk	> Emerging Market Risk: Emerging markets securities may be more volatile, or more greatly affected by negative conditions, than those of their counterparts in more established foreign markets. Such securities may also be subject to Sanctions Risk.
Equity Linked Notes (ELNs) Risk	> Equity Linked Notes (ELNs) Risk: When the fund invests in ELNs, it receives cash but limits its opportunity to profit from an increase in the market value of the reference benchmark because of the limits relating to the call options written within the particular ELN. Investments in ELNs often have risks similar to the reference benchmark, which include market risk. Should the price of the reference benchmark move in an unexpected manner, the fund may not achieve the anticipated benefits of an investment in an ELN, and may realize losses, which could be significant and could include the fund’s entire principal investment.
Focused Investment Risk	> Focused Investment Risk: To the extent the fund focuses its investments on a limited number of issuers, sectors, industries, geographic regions or portfolio themes, it may be subject to increased risk and volatility.
Foreign Investing Risk	> Foreign Investing Risk: Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; less publicly available information about the foreign investment; and political, regulatory, economic, and market risk.
Growth Stocks Risk	> Growth Stocks Risk: The fund’s investments in growth stocks may be more volatile than investments in other types of stocks, or may perform differently from the market as a whole and from other types of stocks.
Income Risk	> Income Risk: Income received from the fund may vary widely over the short- and long-term and/or be less than anticipated if the proceeds from maturing securities in the fund are reinvested in lower-yielding securities.
Interest Rate Risk	> Interest Rate Risk: The values of debt instruments may rise or fall in response to changes in interest rates, and this risk may be enhanced for securities with longer maturities.
Large Market Capitalization Companies Risk	> Large Market Capitalization Companies Risk: The value of investments in larger companies may not rise as much as smaller companies, or larger companies may be unable to respond quickly to competitive challenges, such as changes in technology and consumer tastes.
Leverage Risk	> Leverage Risk: When the fund leverages its portfolio by borrowing or by engaging in certain types of transactions or instruments, including derivatives, the fund may be less liquid, may liquidate positions at an unfavorable time, and the volatility of the fund’s value may increase.
Liquidity Risk	> Liquidity Risk: Certain instruments may be difficult or impossible to sell at a time and price beneficial to the fund.
Redemption Risk	> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken.

Foreign Investing Risk	> Foreign Investing Risk: Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; less publicly available information about the foreign investment; and political, regulatory, economic, and market risk.
Emerging Market Risk	> Emerging Market Risk: Emerging markets securities may be more volatile, or more greatly affected by negative conditions, than those of their counterparts in more established foreign markets. Such securities may also be subject to Sanctions Risk.
Investing in China Risk	> Investing in China Risk: The government of China maintains strict currency controls in order to achieve economic, trade and political objectives and regularly intervenes in the currency market. The Chinese government also plays a major role in the country’s economic policies regarding foreign investments. Foreign investors are subject to the risk of loss from expropriation or nationalization of their investment assets and property, governmental restrictions on foreign investments and the repatriation of capital invested. In addition, the rapid growth rate of the Chinese economy over the past several years may not continue, and the trend toward economic liberalization and disparities in wealth may result in social disorder, including violence and labor unrest. These and other factors could have a negative impact on the fund’s performance and increase the volatility of an investment in the fund. Certain securities issued by companies located or operating in China, such as China A-shares, are also subject to trading restrictions, quota limitations and less market liquidity, which could pose risks to the fund.
Sanctions Risk	> Sanctions Risk: The imposition of sanctions and other similar measures could cause a decline in the value and/or liquidity of securities issued by or tied to the sanctioned country and increase market volatility and disruption in the sanctioned country and throughout the world. Sanctions and other similar measures could limit or prevent the fund from buying and selling securities (in the sanctioned country and other markets), significantly delay or prevent the settlement of transactions, and negatively impact the fund’s liquidity and performance.
Small and Medium Market Capitalization Companies Risk	> Small and Medium Market Capitalization Companies Risk: The fund’s investments in small and medium market capitalization companies may increase the volatility and risk of loss to the fund, as compared with investments in larger, more established companies.
Counterparty Risk	> Counterparty Risk: There is risk that a party upon whom the fund relies to complete a transaction will default.
Credit Risk	> Credit Risk: If the issuer of a debt instrument fails to pay interest or principal in a timely manner, or negative perceptions exist in the market of the issuer’s ability to make such payments, the price of the security may decline.
Currency Rate Risk	> Currency Rate Risk: Fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect the value of the fund’s shares.
Depositary Receipts Risk	> Depositary Receipts Risk: Investments in foreign companies through depositary receipts may expose the fund to the same risks as direct investments in securities of foreign issuers.
Focused Investment Risk	> Focused Investment Risk: To the extent the fund focuses its investments on a limited number of issuers, sectors, industries, geographic regions or portfolio themes, it may be subject to increased risk and volatility.
Liquidity Risk	> Liquidity Risk: Certain instruments may be difficult or impossible to sell at a time and price beneficial to the fund.
Portfolio Turnover Risk	> Portfolio Turnover Risk: The fund’s principal investment strategies may result in a high portfolio turnover rate. See the “Portfolio Turnover” section above for more information about the impact that portfolio turnover can have on your investment.
Preferred Stocks Risk	> Preferred Stocks Risk: Preferred stocks may decline in price, fail to pay dividends when expected, or be illiquid.
Real Estate Investment Risk	> Real Estate Investment Risk: The fund may be negatively affected by changes in real estate values or economic conditions, credit risk and interest rate fluctuations, changes in the value of the underlying real estate and defaults by lessees and/or borrowers.
Redemption Risk	> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of fund shares would particularly impact non-redeeming shareholders who do not hold their fund shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund’s net asset value and liquidity. In addition, a large redemption could result in the fund’s current expenses being allocated over a smaller asset base, leading to an increase in the fund’s expense ratio.
Value Stocks Risk	> Value Stocks Risk: The fund may underperform when value investing is out of favor or the fund’s investments may not appreciate in value as anticipated. Please see “More Information About Risks of Investing in the Funds” in the fund’s prospectus for a more detailed description of the fund’s risks.

Market Volatility Risk	> Market Volatility Risk: The value of the securities in the fund may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be short- or long-term. Local, regional or global events such as war or military conflict (e.g., Russia’s invasion of Ukraine), geopolitical risk, acts of terrorism, the spread of infectious illness or other public health issue, recessions, tariffs and other restrictions on trade, or the threat or potential of one or more such events and developments, could have a significant impact on the fund and its investments, including hampering the ability of the fund’s portfolio manager(s) to invest the fund’s assets as intended.
Issuer Risk	> Issuer Risk: The fund will be affected by factors specific to the issuers of securities and other instruments in which the fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers.
Equity Securities Risk	> Equity Securities Risk: The value of the stocks held by the fund may be negatively affected by the financial market, industries in which the fund invests, or issuer-specific events. Focus on a particular style or in small or medium-sized companies may enhance that risk.
Foreign Investing Risk	> Foreign Investing Risk: Investing in foreign securities subjects the fund to additional risks such as increased volatility; currency fluctuations; less liquidity; less publicly available information about the foreign investment; and political, regulatory, economic, and market risk.
Counterparty Risk	> Counterparty Risk: There is risk that a party upon whom the fund relies to complete a transaction will default.
Credit Risk	> Credit Risk: If the issuer of a debt instrument fails to pay interest or principal in a timely manner, or negative perceptions exist in the market of the issuer’s ability to make such payments, the price of the security may decline.
Currency Rate Risk	> Currency Rate Risk: Fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect the value of the fund’s shares.
Depositary Receipts Risk	> Depositary Receipts Risk: Investments in foreign companies through depositary receipts may expose the fund to the same risks as direct investments in securities of foreign issuers.
Derivatives Risk	> Derivatives Risk: Derivatives and other similar instruments (collectively referred to in this section as “derivatives”) may include, among other things, futures, options, forwards, and swap agreements, and may be used in order to hedge portfolio risks, create leverage or attempt to increase returns. Investments in derivatives may result in increased volatility and the fund may incur a loss greater than its principal investment.
Focused Investment Risk	> Focused Investment Risk: To the extent the fund focuses its investments on a limited number of issuers, sectors, industries, geographic regions or portfolio themes, it may be subject to increased risk and volatility.
IPO Risk	> IPO Risk: Securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility.
Leverage Risk	> Leverage Risk: When the fund leverages its portfolio by borrowing or by engaging in certain types of transactions or instruments, including derivatives, the fund may be less liquid, may liquidate positions at an unfavorable time, and the volatility of the fund’s value may increase.
Liquidity Risk	> Liquidity Risk: Certain instruments may be difficult or impossible to sell at a time and price beneficial to the fund.
Portfolio Turnover Risk	> Portfolio Turnover Risk: The fund’s principal investment strategies may result in a high portfolio turnover rate. See the “Portfolio Turnover” section above for more information about the impact that portfolio turnover can have on your investment.
Preferred Stocks Risk	> Preferred Stocks Risk: Preferred stocks may decline in price, fail to pay dividends when expected, or be illiquid.
Real Estate Investment Risk	> Real Estate Investment Risk: The fund may be negatively affected by changes in real estate values or economic conditions, credit risk and interest rate fluctuations, changes in the value of the underlying real estate and defaults by lessees and/or borrowers.
Redemption Risk	> Redemption Risk: One or more large shareholders or groups of shareholders may redeem their holdings in the fund, resulting in an adverse impact on remaining shareholders in the fund by causing the fund to take actions it would not otherwise have taken. The effects of taxable gains resulting from large redemptions of fund shares would particularly impact non-redeeming shareholders who do not hold their fund shares in a tax-advantaged or tax-exempt vehicle. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause a fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the fund’s net asset value and liquidity. In addition, a large redemption could result in the fund’s current expenses being allocated over a smaller asset base, leading to an increase in the fund’s expense ratio.
Small and Medium Market Capitalization Companies Risk	> Small and Medium Market Capitalization Companies Risk: The fund’s investments in small and medium market capitalization companies may increase the volatility and risk of loss to the fund, as compared with investments in larger, more established companies. Please see “More Information About Risks of Investing in the Funds” in the fund’s prospectus for a more detailed description of the fund’s risks.
