Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund uses a “passive management” (or indexing) approach to track the performance, before fees and expenses, of the Index. The Index follows a rules-based methodology (described generally below) that tracks the performance of 500 of the largest U.S.-listed companies weighted based on a proprietary mix of their market capitalization and fundamental factors. The Index is owned and administered by Solactive AG (the “Index Provider”), and the Index Provider partnered with Social Finance, Inc. (“SoFi”) to co-develop the methodology used by the Index to determine the securities included in the Index. SoFi is not involved in the ongoing maintenance of the Index or any discretionary decisions relating to its application, and does not act in the capacity of an index provider. SoFi has licensed certain of its trademarks to the Index Provider for use in connection with the Index.
Solactive SoFi US 500 Growth Index
Construction of the Index begins with the selection of the 500 largest constituents by market capitalization of the Solactive US Broad Market Index, a market capitalization-weighted index that includes equity securities of approximately 3,000 of the largest U.S. companies. This selection is subject to a 20% buffer rule to limit index turnover. The Index may include common stocks and equity interests in real estate investment trusts (“REITs”).
The weight of each Index constituent is initially based on each constituent’s free-float market capitalization and then adjusted upward or downward based on a proprietary composite score calculated based on three growth-oriented fundamental factors of each company: trailing 12-month sales growth, trailing 12-month earnings per share (“EPS”) growth, and 12-month forward-looking EPS growth consensus estimates. For each factor, the scores for all Index constituents are adjusted to account for outliers, and each company’s score is calculated relative to the average score for that factor. The composite score for a company reflects an average of that company’s score for each factor.
The Index is rebalanced and reconstituted annually, effective on the first Wednesday of each May based on data as of the tenth business day prior to the reconstitution date. As of May 28, 2021, the three largest Index constituents and the weights were as follows: Amazon.com Inc. 5.86%; Apple Inc. 5.14%; and Microsoft Corp. 4.98%.
The Fund’s Investment Strategy
The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Index. The Fund’s investment adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it generally will invest in all of the component securities of the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole, when the Fund’s investment adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
The Fund generally may invest up to 20% of its total assets (exclusive of any collateral held from securities lending) in securities or other investments not included in the Index, but which the Fund’s investment adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).
To the extent the Index concentrates (i.e., holds more than 25% of its total assets in the securities of a particular industry or group of related industries), the Fund will concentrate its investments to approximately the same extent as the Index.
The Fund may actively and frequently trade all or a significant portion of the securities in its portfolio.

Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
The principal risks of investing in the Fund are summarized below. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return, and/or ability to meet its objective. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds—Principal Risks of Investing in Each Fund.”
The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with those of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.
•Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
•Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.
•ETF Risk.
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption
orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.
◦Trading. Although Shares are listed on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.
•General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, pandemic diseases, terrorism, regulatory events, and government controls.
•High Portfolio Turnover Risk. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.
•Limited Operating History Risk. The Fund has a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
•Market Capitalization Risk.
◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
◦Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole.
•Models and Data Risk. The composition of the Index is heavily dependent on proprietary quantitative models as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Index universe that would have been excluded or included had the Models and Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to also reflect the errors.
•Passive Investment Risk. The Fund invests in the securities included in, or representative of, its Index regardless of their investment merit. The Fund does not attempt to outperform its Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index.
•Recent Market Events Risk. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including the impact of the novel coronavirus (COVID-19) as a global pandemic, which has resulted in public health issues, growth concerns in the U.S. and overseas, layoffs, rising unemployment claims, changed travel and social behaviors, and reduced consumer spending. The effects of COVID-19 may lead to a substantial economic downturn or recession in the U.S. and global economies, the recovery from which is uncertain and may last for an extended period of time. These developments as well as other events could result in further market volatility and negatively affect financial asset prices, the liquidity of certain securities and the normal operations of securities exchanges and other markets.
•REIT Risk. Through its investments in REITs, the Fund is subject to the risks of investing in the real estate market, including decreases in property revenues, increases in interest rates, increases in property taxes and operating expenses, legal and regulatory changes, a lack of credit or capital, defaults by borrowers or tenants, environmental problems and natural disasters.
REITs are subject to additional risks, including those related to adverse governmental actions; declines in property value and the real estate market; the potential failure to qualify for tax-free pass through of income; and exemption from registration as an investment company. REITs are dependent upon specialized management skills and may invest in relatively few properties, a small geographic area, or a small number of property types. As a result, investments in REITs may be volatile. To the extent the Fund invests in REITs concentrated in specific geographic areas or property types, the Fund may be subject to a greater loss as a result of adverse developments affecting such area or property types. REITs are pooled investment vehicles with their own fees and expenses and the Fund will indirectly bear a proportionate share of those fees and expenses.
•Sector Risk. At times the Fund may increase the relative emphasis of its investments in a particular sector or group of industries. The prices of securities of issuers in a particular sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of Shares may fluctuate in response to events affecting that industry or sector.
•Tracking Error Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
The principal risks of investing in the Fund are summarized below. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return, and/or ability to meet its objective. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds—Principal Risks of Investing in Each Fund.”
The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with those of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.
•Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
•Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.
•ETF Risk.
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption
orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices.

In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.
•General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, pandemic diseases, terrorism, regulatory events, and government controls.
•High Portfolio Turnover Risk. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.
•Limited Operating History Risk. The Fund has a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
•Market Capitalization Risk.
◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
◦Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole.
•Models and Data Risk. The composition of the Index is heavily dependent on proprietary quantitative models as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Index universe that would have been excluded or included had the Models and Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to also reflect the errors.
•Passive Investment Risk. The Fund invests in the securities included in, or representative of, its Index regardless of their investment merit. The Fund does not attempt to outperform its Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index.
•Recent Market Events Risk. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including the impact of the novel coronavirus (COVID-19) as a global pandemic, which has resulted in public health issues, growth concerns in the U.S. and overseas, layoffs, rising unemployment claims, changed travel and social behaviors, and reduced consumer spending. The effects of COVID-19 may lead to a substantial economic downturn or recession in the U.S. and global economies, the recovery from which is uncertain and may last for an extended period of time. These developments as well as other events could result in further market volatility and negatively affect financial asset prices, the liquidity of certain securities and the normal operations of securities exchanges and other markets.
•REIT Risk. Through its investments in REITs, the Fund is subject to the risks of investing in the real estate market, including decreases in property revenues, increases in interest rates, increases in property taxes and operating expenses, legal and regulatory changes, a lack of credit or capital, defaults by borrowers or tenants, environmental problems and natural disasters.
REITs are subject to additional risks, including those related to adverse governmental actions; declines in property value and the real estate market; the potential failure to qualify for tax-free pass through of income; and exemption from registration as an investment company. REITs are dependent upon specialized management skills and may invest in relatively few properties, a small geographic area, or a small number of property types. As a result, investments in REITs may be volatile. To the extent the Fund invests in REITs concentrated in specific geographic areas or property types, the Fund may be subject to a greater loss as a result of adverse developments affecting such area or property types. REITs are pooled investment vehicles with their own fees and expenses and the Fund will indirectly bear a proportionate share of those fees and expenses.
•Sector Risk. At times the Fund may increase the relative emphasis of its investments in a particular sector or group of industries. The prices of securities of issuers in a particular sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of Shares may fluctuate in response to events affecting that industry or sector.
•Tracking Error Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund uses a “passive management” (or indexing) approach to track the performance, before fees and expenses, of the Index. The Index follows a rules-based methodology (described generally below) that tracks the performance of a portfolio of the 50 most widely held U.S.-listed equity securities in self-directed brokerage accounts (the “SoFi Accounts”) of SoFi Securities, LLC, an affiliate of Social Finance, Inc. (“SoFi”), as determined using the rules-based methodology. The Index is owned and administered by Solactive AG (the “Index Provider”), which engaged SoFi to develop the rules set and related methodology used to determine the securities to be included in the Index. SoFi is not involved in the ongoing maintenance of the Index or any discretionary decisions relating to its application, and does not act in the capacity of an index provider. SoFi has licensed certain of its trademarks to the Index Provider for use in connection with the Index.
SoFi Social 50 Index
The Index is designed to reflect the 50 most widely held U.S.-listed equity securities in the SoFi Accounts as weighted by aggregate holdings within the SoFi Accounts. Securities eligible for inclusion in the Index must: (a) be U.S.-listed equity securities held in SoFi Accounts, and (b) have an average daily trading volume of at least $10,000,000 during the preceding one-month and six-month periods (the “Eligible Universe”). The Index may include common stocks and equity interests in real estate investment trusts (“REITs”). ETFs and other investment companies are not eligible for the Index. Securities in the Eligible Universe are sorted based on (1) the number of SoFi Accounts that hold a particular security and (2) the total market value of the security held in the SoFi Accounts (the “Weighted Average Value”). Each security in the Eligible Universe is then ranked from highest to lowest based on its Weighted Average Value (e.g., the security with the highest Weighted Average Value is assigned rank 1). Subject to a “buffer rule” aimed at limiting Index turnover, securities ranked within the top 50 are included in the Index.
Each security in the Index is then weighted based on its Weighted Average Value in relation to that of the other Index components and is subject to certain individual security weight and sector concentration caps. For example, the weight of each individual Index component is capped at 10%, and securities representing investments in any particular industry sector are capped at 50%. The Index is rebalanced and reconstituted monthly.
As of May 31, 2021, the SoFi Accounts consisted of over 300,000 separate self-directed brokerage accounts.
The Fund’s Investment Strategy
The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Index. The Fund’s investment adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it generally will invest in all of the component securities of the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole, when the Fund’s investment adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
The Fund generally may invest up to 20% of its total assets (exclusive of any collateral held from securities lending) in securities or other investments not included in the Index, but which the Fund’s investment adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).
To the extent the Index concentrates (i.e., holds more than 25% of its total assets in the securities of a particular industry or group of related industries), the Fund will concentrate its investments to approximately the same extent as the Index.
The Fund may actively and frequently trade all or a significant portion of the securities in its portfolio.

Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
The principal risks of investing in the Fund are summarized below. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return, and/or ability to meet its objective. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds—Principal Risks of Investing in Each Fund.”
The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with those of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.
•Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
•Data Risk.  The composition of the Index is heavily dependent on information and data supplied by third parties. When such data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Index universe that would have been excluded or included had the data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to also reflect the errors.
•Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.
•ETF Risk.
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and
possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.
◦Trading. Although Shares are listed on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.
•General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, pandemic diseases, terrorism, regulatory events, and government controls.
•High Portfolio Turnover Risk. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.
•Limited Operating History Risk. The Fund has a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
•Market Capitalization Risk.
◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
◦Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole.
•Passive Investment Risk. The Fund invests in the securities included in, or representative of, its Index regardless of their investment merit. The Fund does not attempt to outperform its Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index.
•Recent Market Events Risk. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including the impact of the novel coronavirus (COVID-19) as a global pandemic, which has resulted in public health issues, growth concerns in the U.S. and overseas, layoffs, rising unemployment claims, changed travel and social behaviors, and reduced consumer spending. The effects of COVID-19 may lead to a substantial economic downturn or recession in the U.S. and global economies, the recovery from which is uncertain and may last for an extended period of time. These developments as well as other events could result in further market volatility and negatively affect financial asset prices, the liquidity of certain securities and the normal operations of securities exchanges and other markets.
•REIT Risk. Through its investments in REITs, the Fund is subject to the risks of investing in the real estate market, including decreases in property revenues, increases in interest rates, increases in property taxes and operating expenses, legal and regulatory changes, a lack of credit or capital, defaults by borrowers or tenants, environmental problems and natural disasters.
REITs are subject to additional risks, including those related to adverse governmental actions; declines in property value and the real estate market; the potential failure to qualify for tax-free pass through of income; and exemption from registration as an investment company. REITs are dependent upon specialized management skills and may invest in relatively few
properties, a small geographic area, or a small number of property types. As a result, investments in REITs may be volatile. To the extent the Fund invests in REITs concentrated in specific geographic areas or property types, the Fund may be subject to a greater loss as a result of adverse developments affecting such area or property types. REITs are pooled investment vehicles with their own fees and expenses and the Fund will indirectly bear a proportionate share of those fees and expenses.
•Sector Risk. At times the Fund may increase the relative emphasis of its investments in a particular sector or group of industries. The prices of securities of issuers in a particular sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of Shares may fluctuate in response to events affecting that industry or sector.
◦Communication Services Sector Risk. The Fund may invest in companies in the communication services sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Communication services companies are susceptible to the risk of potential obsolescence of products and services due to technological advancements and innovation competition among companies. Demand for product, shifting consumer demographics and shifting consumer preferences can drastically affect a communication services company's profitability. Companies in the communication services sector may be particular targets of cyber-security losses and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation.
◦Consumer Staples Sector Risk. The Fund may invest in companies in the consumer staples sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Companies in the consumer staples sector, including those in the food and beverage industries, may be affected by general economic conditions, commodity production and pricing, consumer confidence and spending, consumer preferences, interest rates, product cycles, marketing campaigns, competition, and government regulations.
•Tracking Error Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.
•User Bias Risk. The securities that comprise the Index are selected by retail investors holding SoFi Accounts, who may not be professional investors, may have no financial expertise, and may not do any research on the companies in which they invest prior to investing. In some cases, investment decisions made may be influenced by non-quantitative factors, including, without limitation, cognitive and emotional biases, resulting in the inclusion of certain securities in the Index which may underperform the market generally and result in lower returns for the Fund.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund is an actively-managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective primarily by investing in a portfolio of companies listed globally that Toroso Investments, LLC, the Fund’s investment adviser (the “Adviser”), considers part of the “gig economy”. The “gig economy” refers to the group of companies that have embraced, that support, or that otherwise benefit from a workforce where individual employees or independent contractors are empowered to create their own freelance business by leveraging recent developments in technology platforms that enable individuals to offer their services directly to retail and commercial customers. Examples of gig economy businesses include selling or reselling products through auction platforms or web-based stores and offering delivery services through an app-based platform.
The Adviser considers the gig economy to include five categories of companies, and constructs the Fund’s portfolio based on the following weights:
30% to 60%Companies that directly facilitate and participate in revenue generation from gig economy businesses (e.g., app-based platforms, auction sites, web-based stores, and other commission-based platforms)
20% to 40%Companies that enable or support gig economy businesses in marketing and sales functions (e.g., social media platforms, messaging platforms)
5% to 20%Companies that facilitate financial transactions for gig economy businesses through apps or web-based platforms
5% to 15%Companies that support the ability of individuals to operate a gig economy business without participating in a commission or revenue-based model (e.g., companies providing health care, technology, or other back office services)
0% to 10%Other companies that are expected to benefit from the growth of gig economy businesses and associated lifestyle changes for individuals engaged in gig economy businesses
The Adviser purchases and sells securities based on changes in the Adviser’s assessment of which companies are likely to benefit the most from their role in the gig economy. The Fund may invest in equity securities of large-, mid-, and small-capitalization companies listed on a U.S., non-U.S. developed, or emerging markets exchange. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. The Fund may actively and frequently trade all or a significant portion of the securities in its portfolio.
The Fund may invest significantly in companies in the communication services sector.
Risk [Heading] rr_RiskHeading Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
The principal risks of investing in the Fund are summarized below. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return, and/or ability to meet its objective. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds—Principal Risks of Investing in Each Fund.”
The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with those of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.
•Currency Exchange Rate Risk. The Fund’s assets may include exposure to investments denominated in non-U.S. currencies or in securities or other assets that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investments and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.
•Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
•Emerging Markets Risk. The Fund may invest in securities issued by companies domiciled or headquartered in emerging market nations. Investments in securities traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, currency, or regulatory conditions not associated with investments in U.S. securities and investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell, or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value.
•Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.
•ETF Risk.
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.
◦Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.
•Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices.
•General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, pandemic diseases, terrorism, regulatory events, and government controls.
•High Portfolio Turnover Risk. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.
•Limited Operating History Risk. The Fund has a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
•Management Risk. The Fund is actively-managed and may not meet its investment objective based on the Adviser’s success or failure to implement investment strategies for the Fund.
•Market Capitalization Risk.
◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.
◦Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole.
◦Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.
•Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
•Recent Market Events Risk. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including the impact of the novel coronavirus (COVID-19) as a global pandemic, which has resulted in public health issues, growth concerns in the U.S. and overseas, layoffs, rising unemployment claims, changed travel and social behaviors, and reduced consumer spending. The effects of COVID-19 may lead to a substantial economic downturn or recession in the U.S. and global economies, the recovery from which is uncertain and may last for an extended period of time. These developments as well as other events could result in further market volatility and negatively affect financial asset prices, the liquidity of certain securities and the normal operations of securities exchanges and other markets.
•Sector Risk. At times the Fund may increase the relative emphasis of its investments in a particular sector or group of industries. The prices of securities of issuers in a particular sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of Shares may fluctuate in response to events affecting that industry or sector.◦Communication Services Sector Risk. The Fund may invest in companies in the communication services sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Communication services companies are susceptible to the risk of potential obsolescence of products and services due to technological advancements and innovation competition among companies. Demand for product, shifting consumer demographics and shifting consumer preferences can drastically affect a communication services company's profitability. Companies in the communication services sector may be particular targets of cyber-security losses and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses. Companies in the communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund is an actively-managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective, under normal circumstances, by investing in U.S.-dollar denominated investment grade and non-investment grade (also known as “high-yield” or “junk”) fixed income securities and instruments and expects to distribute income from its investments to shareholders weekly. The Fund anticipates making its weekly income distributions each Friday (or, in the event the NYSE is closed for trading on Friday, on a day earlier in the week). While obligations of any maturity may be purchased, under normal circumstances, the Fund will generally have a short to intermediate overall effective duration (i.e., typically less than three years). Effective duration is a measure of the Fund’s price sensitivity to changes in yields or interest rates and a fund with a higher effective duration will, under normal circumstances, have a greater sensitivity to interest rates. For example, if a portfolio has a duration of one year, and interest rates increase (fall) by 2%, the portfolio would decline (increase) in value by approximately 2%. However, duration may not accurately reflect the true interest rate sensitivity of instruments held by the Fund and, therefore, the Fund’s exposure to changes in interest rates.
Investment decisions for the Fund are made by Income Research + Management (“IR+M” or the “Sub-Adviser”), the Fund’s sub-adviser, primarily through a fundamental analysis of available debt instruments and their issuers. IR+M applies a bottom-up investing approach focusing on the analysis of individual companies rather than on the industry or sector in which a company operates or on the economy as a whole.
IR+M’s bottom-up process focuses on the following attributes of investment opportunities:
CreditIR+M evaluates the strength of a company’s management, its financial statements, and its competitive position in its industry or peer group.
StructureIR+M focuses on the shape of the curve reflecting the relationship of a bond’s price to interest rates (also known as “convexity”) with a particular interest in the extent to which an instrument may be callable (i.e., the issuer can redeem the bond prior to its maturity date) or have other such options attached to it that may affect the bond’s convexity. This analysis favors bonds with positive convexity (i.e., where the price would be expected to increase as interest rates rise) and those with structures that may add to the bond’s effective yield without increasing credit risk.
PriceIR+M seeks bonds that it believes are under- or mis-priced and will seek to avoid bonds it determines are overpriced.
The Fund may invest in a variety of fixed income instruments with a fixed or floating (variable) interest rate. The Fund may hold U.S government securities, including Treasury securities, Treasury Inflation Protected Securities (“TIPS”), and agency bonds. The Fund may also invest in corporate debt, commercial and residential mortgage-backed securities (“CMBS” and “RMBS”, respectively) (including collateralized mortgage obligations (“CMOs”), including interest only and principal only instruments), asset-backed securities (“ABS”), municipal securities, convertible securities, pass-through securities, and U.S. dollar denominated securities issued or guaranteed by foreign governments, their agencies, or instrumentalities, and floating rate securities (such as bank loans). The Fund may also invest in non-investment grade bonds (including distressed securities), non-investment grade bank loans, and bonds of emerging market issuers. The Fund’s investment in mortgage-backed securities (“MBS”) may include both agency and non-agency MBS. The portion of the Fund invested in non-investment grade instruments may be up to 100% of the Fund’s total assets.
The Fund may purchase or sell securities on a when-issued, delayed delivery, or forward commitment basis, including the use of the “To Be Announced” (“TBA”) market for MBS investments. The Fund may invest up to 15% of its net assets in securities that are deemed to be illiquid, which may include private placements, certain Rule 144A securities (which are subject to resale restrictions), and securities of issuers that are bankrupt or in default.
The Fund may actively and frequently trade the Fund’s all or a significant portion of the securities in its portfolio.
The Fund is expected to generally have significant exposure to companies in the financial services and industrials sectors, although the Fund will not concentrate (i.e., investment more than 25% of its total assets) in any particular industry. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with those of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.
•ABS Risk. The value of ABS may be significantly affected by changes in interest rates, the market’s perception of issuers, and the creditworthiness of the parties involved. These securities may have a structure that makes their reaction to interest rate changes and other factors difficult to predict, making their value highly volatile.
•Agency Debt Risk. Bonds or debentures issued by U.S. government agencies, government-sponsored entities, or government corporations, including, among others, Federal National Mortgage Association (“Fannie Mae”) and Federal Home Loan Mortgage Corporation (“Freddie Mac”), are generally backed only by the general creditworthiness and reputation of the U.S. government agency, government-sponsored entity, or government corporation issuing the bond or debenture and are not guaranteed by the U.S. Department of the Treasury (“U.S. Treasury”) or backed by the full faith and credit of the U.S. government. As a result, there is uncertainty as to the current status of many obligations of Fannie Mae, Freddie Mac and other agencies that are placed under conservatorship of the federal government. By contrast, Government National Mortgage Association securities are generally backed by the full faith and credit of the U.S. government.
•Bank Loans Risk. Bank loans often involve borrowers whose financial conditions are troubled or uncertain and companies that are highly leveraged. The market for bank loans may not be highly liquid and the Fund may have difficulty selling bank loans. These investments expose the Fund to the credit risk of both the financial institution and the underlying borrower. Bank loans generally are subject to legal or contractual restrictions on resale. In addition, bank loans may have trade settlement periods extending beyond seven days, which means that, in certain cases, it could take the Fund a significant amount of time to get its money after selling an investment. Bank loans may be structured such that they are not “securities” under federal securities laws and therefore not subject to federal securities laws protections against fraud and misrepresentation. As such, there can be no assurances that fraud or misrepresentation will not occur with respect to bank loans in which the Fund invests.
•Call Risk. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” or repay the security prior to its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income.
•Convertible Securities Risk. Convertible securities rank senior to the issuer's common stock, but may be subordinate to senior debt obligations. In part, the total return for a convertible security may depend upon the performance of the underlying stock into which it can be converted. Synthetic convertibles may respond differently to market fluctuations than traditional convertible securities. They are also subject to counterparty risk.
•CMBS Risk. The Fund’s investments in CMBS are subject to the risk that if there is a shortfall in loan payments from borrowers or if an underlying property is sold via foreclosure and does not generate sufficient proceeds to meet scheduled payments on all bond classes, investments in the most subordinate outstanding bond class will incur a principal loss first, with any further losses impacting more senior classes in reverse order of payment priority. CMBS are historically more volatile than RMBS. Such securities are subject to credit, interest rate, prepayment, and extension risks.
•CMOs Risk. CMOs represent interests in a short-term, intermediate-term or long-term portion of a mortgage pool. Each portion of the pool receives monthly interest payments, but the principal repayments pass through to the short-term CMO first and to the long-term CMO last. Investments in CMOs are subject to the same risks as direct investments in the underlying mortgage-backed securities including credit, interest rate, prepayment, and extension risks. In the event of a bankruptcy or other default of a broker who issued the CMO held by the Fund, the Fund could experience both delays in liquidating its position and losses. In addition, classes of CMOs may also include interest only (“IOs”) and principal only (“POs”). IOs and POs are stripped mortgage-backed securities representing interests in a pool of mortgages the cash flow from which has been separated into interest and principal components. IOs (interest only securities) receive the interest portion of the cash flow while POs (principal only securities) receive the principal portion. IOs and POs can be extremely volatile in response to changes in interest rates. As interest rates rise and fall, the value of IOs tends to move in the same direction as interest rates. When payments on mortgages underlying a PO are slow, the life of the PO is lengthened and the yield to maturity is reduced.
•Credit Risk. Issuers and/or counterparties may fail to make payments when due or default completely. If an issuer’s or counterparty’s financial condition worsens, the credit quality of the issuer or counterparty may deteriorate, making it difficult for the Fund to sell such investments. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of an investment in that issuer.
•Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
•Emerging Markets Risk. Investments in securities traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, currency, or regulatory conditions not associated with investments in U.S. securities and investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell, or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value.
•ETF Risk.
◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
◦Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments and bonds that cannot be broken up beyond certain minimum sizes needed for transfer and settlement). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.
◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.
◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of ETFs holding only domestic securities.
◦Trading. Although Shares are listed on a national securities exchange, such as NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.
•Event Risk. Corporate issuers may undergo restructurings, such as mergers, leveraged buyouts, takeovers, or similar events financed by increased debt. As a result of the added debt, the credit quality and market value of a company’s bonds and/or other debt securities may decline significantly.
•Extension Risk. When interest rates rise, certain obligations will be repaid by the obligor more slowly than anticipated, causing the value of these securities to fall.
•Fixed Income Risk. The value of the Fund’s investments in fixed income securities will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned indirectly by the Fund. On the other hand, if rates fall, the value of the fixed income securities generally increases. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities.
•Floating or Variable Rate Securities Risk. Securities with floating or variable interest rates are generally less sensitive to interest rate changes than securities with fixed interest rates, but may decline in value if their interest rates do not rise as much, or as quickly, as comparable market interest rates. Although floating or variable rate securities are generally less sensitive to interest rate risk than fixed rate securities, they are subject to credit, liquidity and default risk and may be subject to legal or contractual restrictions on resale, which could impair their value.
•Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices.
•General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters or events, pandemic diseases, terrorism, regulatory events, and government controls.
•High Portfolio Turnover Risk. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.
•High-Yield Securities Risk. High-yield securities (also known as “junk” bonds) carry a greater degree of risk and are more volatile than investment grade securities and are considered speculative. High-yield securities may be issued by companies that are restructuring, are smaller and less creditworthy, or are more highly indebted than other companies. This means that they may have more difficulty making scheduled payments of principal and interest. Changes in the value of high-yield securities are influenced more by changes in the financial and business position of the issuing company than by changes in interest rates when compared to investment grade securities. The Fund’s investments in high-yield securities expose it to a substantial degree of credit risk.
•Illiquid Securities Risk. The Fund may, at times, hold illiquid securities, by virtue of the absence of a readily available market for certain of its investments, or because of legal or contractual restrictions on sales. The Fund could lose money if it is unable to dispose of an investment at a time or price that is most beneficial to the Fund.
•Interest Rate Risk. The Fund’s investments in bonds and other debt securities will change in value based on changes in interest rates. If rates rise, the value of these investments generally declines. Securities with greater interest rate sensitivity and longer maturities generally are subject to greater fluctuations in value.
•LIBOR Risk. Instruments in which the Fund invests may pay interest at floating rates based on the London Interbank Offered Rate (“LIBOR”) or may be subject to interest caps or floors based on LIBOR. The Fund and issuers of instruments in which the Fund invests may also obtain financing at floating rates based on LIBOR. Derivative instruments utilized by the Fund and/or issuers of instruments in which the Fund may invest may also reference LIBOR. In July 2017, the head of the United Kingdom Financial Conduct Authority announced the desire to phase out the use of LIBOR by December 31, 2021. There is currently no definitive information regarding the future utilization of LIBOR or of any particular replacement rate. Abandonment of or modifications to LIBOR may affect the value, liquidity or return on certain Fund investments that reference LIBOR without including fallback provisions and may result in costs incurred in connection with closing out positions and entering into new trades. Any pricing adjustments to the Fund’s investments resulting from a substitute reference rate may also adversely affect the Fund’s performance and/or NAV. The effect of a phase out of LIBOR on instruments in which the Fund may invest is currently unclear.
•Limited Operating History Risk. The Fund has a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
•Management Risk. The Fund is actively-managed and may not meet its investment objective based on IR+M’s success or failure to implement investment strategies for the Fund.
•MBS Risk. MBS securities are subject to credit, interest rate, prepayment, and extension risks. 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 may quickly and significantly reduce the value of certain mortgage back securities.
•Municipal Securities Risk. Municipal securities can be significantly affected by political or economic changes, including changes made in the law after issuance of the securities, as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders, including in connection with an issuer insolvency. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the inability to collect revenues from the project or the assets.
•Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
•Prepayment Risk. The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the Fund may have to reinvest in securities with a lower yield. The Fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.
•Privately Placed Securities Risk. Privately placed securities generally are less liquid than publicly traded securities and the Fund may not always be able to sell such securities without experiencing delays in finding buyers or reducing the sale price for such securities. The disposition of some of the securities held by the Fund may be restricted under federal securities laws. As a result, the Fund may not be able to dispose of such investments at a time when, or at a price at which, it desires to do so and may have to bear expenses of registering these securities, if necessary. These securities may also be difficult to value.
•Rating Agencies Risks. Ratings are not an absolute standard of quality. Ratings are general indicators that reflect only the view of the originating rating agencies from which an explanation of the significance of such ratings may be obtained. There is no assurance that a particular rating will continue for any given period of time or that any such rating will not be revised downward or withdrawn entirely. Such changes may negatively affect the liquidity or market price of the securities in which the Fund invests. The ratings of securitized assets may not adequately reflect the credit risk of those assets due to their structure.
•Recent Market Events Risk. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including the impact of the novel coronavirus (COVID-19) as a global pandemic, which has resulted in public health issues, growth concerns in the U.S. and overseas, layoffs, rising unemployment claims, changed travel and social behaviors, and reduced consumer spending. The effects of COVID-19 may lead to a substantial economic downturn or recession in the U.S. and global economies, the recovery from which is uncertain and may last for an extended period of time. These developments as well as other events could result in further market volatility
and negatively affect financial asset prices, the liquidity of certain securities and the normal operations of securities exchanges and other markets.
•RMBS Risk. RMBS are particularly susceptible to prepayment risks, as they generally do not contain prepayment penalties and a reduction in interest rates will increase the prepayments on the RMBS. Such securities are also subject to credit, interest rate, and extension risks.
•Sector Risk. At times the Fund may increase the relative emphasis of its investments in a particular sector or group of industries. The prices of securities of issuers in a particular sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of Shares may fluctuate in response to events affecting that industry or sector.
◦Financial Services Sector Risk. The Fund may invest in companies in the financial services sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. This sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt and the availability and cost of capital, among other factors. Insurance companies, in particular, may be significantly affected by changes in interest rates, catastrophic events, price and market competition, the imposition of premium rate caps, or other changes in government regulation or tax law and/or rate regulation, which may have an adverse impact on their profitability. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses.
◦Industrials Sector Risk. The Fund may invest in companies in the industrials sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The industrials sector may be affected by changes in the supply of and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.
•TBA Securities and Rolls Risk. TBA transactions are subject to increased credit risk and increased overall investment exposure. TBA rolls involve the risk that the Fund’s counterparty will be unable to deliver the MBS underlying the TBA roll at the fixed time. If the buyer files for bankruptcy or becomes insolvent, the buyer or its representative may ask for and receive an extension of time to decide whether to enforce the Fund’s repurchase obligation. In addition, the Fund earns interest by investing the transaction proceeds during the roll period. TBA roll transactions may have the effect of creating leverage in the Fund’s portfolio.
•TIPS Risk. Interest payments on TIPS are unpredictable and will fluctuate as the principal and corresponding interest payments are adjusted for inflation. There can be no assurance that the Consumer Price Index (“CPI”) will accurately measure the real rate of inflation in the prices of goods and services. Any increases in the principal amount of TIPS will be considered taxable ordinary income, even though the Fund will not receive the principal until maturity. As a result, the Fund may make income distributions to shareholders that exceed the cash it receives. In addition, TIPS are subject to credit risk and interest rate risk.
•Uncertain Tax Treatment. Below investment grade instruments may present special tax issues for the Fund. U.S. federal income tax rules are not entirely clear about issues such as when the Fund may cease to accrue interest, original issue discount (“OID”) or market discount, when and to what extent deductions may be taken for bad debts or worthless instruments, how payments received on obligations in default should be allocated between principal and income and whether exchanges of debt obligations in a bankruptcy or workout context are taxable, which may make it difficult for the Fund to satisfy the annual distribution requirements applicable to RICs.
•U.S. Government Obligations Risk. Obligations of U.S. government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so. Additionally, market prices and yields of securities supported by the full faith and credit of the U.S. government or other countries may decline or be negative for short or long periods of time.
•Valuation Risk. The prices provided by the Fund’s pricing services or independent dealers or the fair value determinations made by the Fund’s valuation committee may be different from the prices used by other investment companies or from the prices at which debt obligations are actually bought and sold. The prices of certain debt obligations provided by pricing services may be subject to frequent and significant change, and will vary depending on the information that is available.
•When-Issued, Delayed Delivery, and Forward Commitment Risks. The purchase of securities on a when-issued, delayed delivery, or forward commitment basis involves a risk of loss if the value of the security to be purchased declines prior to the settlement date.
Risk Lose Money [Text] rr_RiskLoseMoney As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.
