Apr. 30, 2026
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] The loss of your money is a principal risk of investing in the Fund.
Risk Nondiversified Status [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Non-Diversification Risk. The Fund is non-diversified. This means that it may invest a larger portion of its assets in a limited number of companies than a diversified fund. Because a relatively high percentage of the Fund’s assets may be invested in the securities of a limited number of companies that could be in the same or related economic sectors, the Fund’s portfolio may be more susceptible to any single economic, technological or regulatory occurrence than the portfolio of a diversified fund.
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Equity Securities Risk. Investments in equity securities may fluctuate in value response to many factors, including general market and economic conditions, interest rates, and specific industry changes. Such price fluctuations subject the Fund to potential losses. During temporary or extended bear markets, the value of equity securities will decline, which could also result in losses for the Fund.
Authorized Participant Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Authorized Participant Risk. Only an authorized participant (“Authorized Participant” or “APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). Authorized Participant concentration risk may be heightened for exchange-traded funds (ETFs), such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.
HealthTech Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
HealthTech Companies Risk:  HealthTech Companies may have limited product lines, markets, financial resources or personnel. Securities of HealthTech Companies, especially smaller, start-up companies, tend to be more volatile than securities of companies that do not rely heavily on technology and may be adversely affected by loss or impairment of those rights. Rapid change to technologies that affect a company’s products could have a material adverse effect on such company’s operating results. HealthTech Companies also rely heavily on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by these companies to protect their proprietary rights will be adequate to prevent the misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology. HealthTech Companies typically engage in significant amounts of spending on research and development, and there is no guarantee that the products or services produced by these companies will be successful. The Fund invests primarily in the equity securities of HealthTech Companies and, as such, is particularly sensitive to risks to those types of companies. These risks include, but are not limited to, changes in business cycles, competition, technological progress and rapid obsolescence, and government regulation. Furthermore, the adoption of AI by HealthTech Companies introduces unique risks, including ethical, regulatory, and safety concerns.
Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Concentration Risk:  Because the Fund invests more heavily in a particular industry, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that industry. As a result, the Fund's share price may fluctuate more widely than the value of shares of a fund that invests in a broader range of industries. Additionally, some industries could be subject to greater government regulation than other industries. Therefore, changes in regulatory policies for those industries may have a material effect on the value of securities issued by companies in those industries.
Small-Cap and Mid-Cap Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Small-Cap and Mid-Cap Securities Risk. The Fund may invest in securities of small-cap and mid-cap companies, which involve greater volatility than investing in larger and more established companies. Small-cap and mid-cap companies can be subject to more abrupt or erratic share price changes than larger, more established companies. Securities of these types of companies have limited market liquidity, and their prices may be more volatile.  You should expect that the value of the Fund’s shares will be more volatile than a fund that invests exclusively in large-capitalization companies.
Large-Cap Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Large-Cap Securities RiskStocks of large companies as a group can fall out of favor with the market, causing the Fund to underperform investments that have a greater focus on mid-cap or small-cap stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.
Foreign Securities [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Foreign Securities. Foreign securities have investment risks different from those associated with domestic securities. The value of foreign investments (including investments in ADRs) may be affected by the value of the local currency relative to the U.S. dollar, changes in exchange control regulations, application of foreign tax laws, changes in governmental economic or monetary policy, or changed circumstances in dealings between nations. There may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information about issuers of foreign securities. In addition, foreign brokerage commissions, custody fees, and other costs of investing in foreign securities are often higher than in the United States. Investments in foreign issues could be affected by other factors not present in the United States, including expropriation, armed conflict, confiscatory taxation, and potential difficulties in enforcing contractual obligations.
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. In managing the Fund’s portfolio securities, the Advisor will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Market Risk.  Market risk refers to the possibility that the value of securities held by the Fund may decline due to daily fluctuations in the market.  Market prices for securities change daily as a result of many factors, including developments affecting the condition of both individual companies and the market in general.  The price of a security may even be affected by factors unrelated to the value or condition of its issuer, including changes in interest rates, economic and political conditions, and general market conditions.  The Fund’s performance per share will change daily in response to such factors.
New Advisor Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
New Advisor Risk. The Advisor has only recently begun serving as an investment advisor. As a result, investors do not have a long-term track record of managing an ETF from which to judge the Advisor, and the Advisor may not achieve the intended result in managing the Fund.
Limited History of Operations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Limited History of Operations Risk. The Fund has a limited history of operations. Accordingly, investors in the Fund bear the risk that the Fund may not be successful in implementing its investment strategy, may not employ a successful investment strategy, or may fail to attract sufficient assets under management to realize economies of scale, any of which could result in the Fund being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders. Such a liquidation could have negative tax consequences for shareholders and will cause shareholders to incur expenses of liquidation.
ETF Structure Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
ETF Structure Risks.  The Fund is structured as an ETF and as a result is subject to the certain risks, including:

o
Not Individually Redeemable.  Shares are not individually redeemable and may be redeemed by the Fund at NAV only in large blocks known as “Creation Units.”  You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit.

o
Trading Issues.  An active trading market for the Fund's shares may not be developed or maintained. Trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility.  There can be no assurance that Shares will continue to meet the listing requirements of the Exchange.  If the Fund's shares are traded outside a collateralized settlement system, the number of financial institutions that can act as authorized participants that can post collateral on an agency basis is limited, which may limit the market for the Fund's shares.
o
Cash purchases. To the extent Creation Units are purchased by APs in cash instead of in-kind, the Fund will incur certain costs such as brokerage expenses and taxable gains and losses. These costs could be imposed on the Fund and impact the Fund’s NAV if not fully offset by transaction fees paid by the APs.

o
Market Price Variance Risk.  The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security.  There may be times when the market price and the NAV vary significantly.  This means that Shares may trade at a discount to NAV.
In times of market stress, market makers may step away from their role market making in shares of ETFs and in executing trades, which can lead to differences between the market value of Shares and the Fund's net asset value.
To the extent Authorized Participants exit the business or are unable to process creations or redemptions and no other Authorized Participant can step in to do so, there may be a significantly reduced trading market in the Fund's shares, which can lead to differences between the market value of Shares and the Fund's net asset value.
The market price for the Fund's shares may deviate from the Fund's net asset value, particularly during times of market stress, with the result that investors may pay significantly more or receive significantly less for Shares than the Fund's net asset value, which is reflected in the bid and ask price for Shares or in the closing price.
When all or a portion of an ETF’s underlying securities trade in a market that is closed when the market for the Fund's shares is open, there may be changes from the last quote of the closed market and the quote from the Fund's domestic trading day, which could lead to differences between the market value of the Fund's shares and the Fund's net asset value.
In stressed market conditions, the market for the Fund's shares may become less liquid in response to the deteriorating liquidity of the Fund's portfolio.  This adverse effect on the liquidity of the Fund's shares may, in turn, lead to differences between the market value of the Fund's shares and the Fund's net asset value.
Cybersecurity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Cybersecurity Risk. With the increased use of technologies such as the internet to conduct business, the Fund, like all companies, may be susceptible to operational, information security, and related risks. As part of its business, the Advisor processes, stores, and transmits large amounts of electronic information, including information relating to the transactions of the Fund. The Fund and its service providers are therefore susceptible to cybersecurity risk. Cybersecurity failures or breaches of the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties and/or reputational damage. The Fund and its shareholders could be negatively impacted as a result.
Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Investment Risk. An investment in Shares is subject to investment risk, including the possible loss of the entire principal amount invested. An investment in shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably. The value of your shares at any point in time may be worth less than the value of your original investment.
All investments involve risks, including the risk that the entire amount invested may be lost. No guarantee or representation is made that the Fund’s investment objectives will be achieved.
Any real or perceived adverse economic changes, local, regional or global events such as war, acts of terrorism, disasters, trade disputes, disputes with specific countries that could result in additional tariffs, trade barriers and/or investment restrictions in certain securities of those countries, the spread of infectious illness or other public health issues, recessions, raising of interest rates, or other events, could have a material adverse impact on the Fund or its investments. Any of these conditions can adversely affect the economic prospects of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen. Moreover, changes in these and other areas present uncertainty and risk with respect to the Fund’s NAV, performance, financial condition, results of operations, ability to pay distributions, and portfolio liquidity, among other factors.
Economic problems in a single country are increasingly affecting other markets and economies, and a continuation of this trend could adversely affect global economic conditions and world markets. Uncertainty and volatility in the financial markets and political systems of the U.S. or any other country, may have adverse spill-over effects into the global financial markets generally.
Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Sector RiskThe fund may be susceptible to an increased risk of loss, including losses due to events that adversely affect the fund's investments more than the market as a whole, to the extent that the fund may, from time to time, have greater exposure to the securities of a particular issuer or issuers within the same industry or sector. Such sector-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, legislative or regulatory changes, adverse market conditions and/or increased competition within the sector. In addition, at times, such sector may be out of favor and underperform other sectors or the market as a whole.

o
Medical Equipment.  Companies in the medical equipment sector are affected by rising costs of medical products, devices and services, and the increased emphasis on the delivery of health care through outpatient services. Competition among medical equipment companies is high and can be significantly affected by extensive government regulation or government reimbursement for medical expenses. The equipment may be subject to extensive litigation based on malpractice claims, product liability claims, or other litigation. Medical equipment manufacturers are heavily dependent on patent protection, and the expiration of patents may adversely affect their profitability. Many new health care products are subject to the approval of the U.S. Food and Drug Administration (“FDA”). The process of obtaining FDA approval is often long and expensive.
Early Close/Trading Halt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may prevent the Fund from buying or selling certain securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and may incur substantial trading losses.
