| Artificial Intelligence Investing Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Artificial Intelligence Investing Risk. Artificial intelligence companies that contribute to or benefit from artificial intelligence technologies (Artificial Intelligence Companies) face intense competition and potentially rapid product obsolescence, and many depend significantly on retaining and growing the consumer base of their respective products and services. Artificial Intelligence Companies may be substantially exposed to market risk generally, and risks of other industries or sectors specifically, and the Fund may be adversely affected by negative developments impacting Artificial Intelligence Companies, and related industries or sectors.
Artificial Intelligence Companies are heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.
Artificial Intelligence Companies may utilize artificial intelligence in their own business operations; such companies’ use of artificial intelligence could result in reputational harm, competitive harm, and legal liability, and/or have an adverse effect on such companies’ business operations and Artificial Intelligence Companies as a whole.
Artificial intelligence technologies and the use of such technology could face increasing regulatory scrutiny in the future, which may limit the development of this technology and impede the growth of Artificial Intelligence Companies.
Artificial Intelligence 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. Securities of Artificial Intelligence Companies, especially smaller companies, tend to be more volatile than those of companies that have a more developed set of product and/or service offerings. |

| Market Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Market Risk. The value of the Fund’s portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund’s NAV may decrease. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. Market risk may be magnified if certain social, political, economic, and other conditions and events (such as financial institution failures, economic recessions, tariffs, trade disputes, terrorism, war, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money. |
||
| Equity Securities Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The value of the Fund’s portfolio may decrease if the value of an individual a company or security, or multiple companies or securities, in the portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions or perceptions regarding the industries which the issuers of securities the Fund holds participate. |
||
| Growth Securities Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Growth Securities Risk. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. If portfolio management’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, reducing the Fund’s returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, “growth” stocks may perform differently from other types of securities and the market as a whole. |
||
| Issuer Concentration Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Issuer Concentration Risk. The Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by the Fund may affect the overall value of the Fund more than it would affect a fund that holds more investments. In particular, the Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments. The Fund’s policy of concentrating its portfolio on a smaller number of holdings could result in more volatility in the Fund’s performance and share price. |
||
| Small and Mid-Sized Companies Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Small and Mid-Sized Companies Risk. The Fund’s investments in securities issued by small and mid-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. For example, they may also suffer more significant losses as a result of their narrow product lines, limited operating history, greater exposure to competitive threats, limited financial resources, limited trading markets, and the potential lack of management depth. Securities issued by small and mid-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities of larger and more established companies. These holdings are also subject to wider price fluctuations and tend to be less liquid than stocks of larger or more established companies, which could have a significant adverse effect on the Fund’s returns, especially as the market conditions change. |
||
| Large-Sized Companies Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Large-Sized Companies Risk. Large-sized companies may be less able than smaller-sized companies to adapt to changing market conditions. Large-sized companies may be more mature and subject to more limited growth potential compared with smaller sized companies. During different market cycles, the performance of large-sized companies has trailed the overall performance of the broader securities markets. |
||
| Industry and Sector Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Industry and Sector Risk. The Fund invests a significant portion of its assets invested in securities of companies conducting similar business or business within the same economic sector. Companies in the same industry or economic sector may be similarly affected by negative economic or market events, making the Fund more vulnerable to unfavorable developments than funds that invest more broadly. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility.
|
||
| Portfolio Management Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Portfolio Management Risk. The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to produce the intended results. Accordingly, the Fund may underperform its benchmark index or other mutual funds with similar investment objectives. |
||
| Foreign Exposure Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Foreign Exposure Risk. Foreign markets can be more volatile than the U.S. market. As a result, the Fund’s returns and NAV may be affected by fluctuations in currency exchange rates or political or economic conditions in a particular country. In some foreign markets, there may not be protection against failure by other parties to complete transactions. It may not be possible for the Fund to repatriate capital, dividends, interest, and other income from a particular country or governmental entity. In addition, a market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. |
||
| Depositary Receipts Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Depositary Receipts Risk. Depositary receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as currency risk, market risk, and foreign exposure risk, because their values depend on the performance of a foreign security denominated in its home currency. |
||
| Emerging Markets Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Emerging Markets Risk. Emerging market securities involve a number of risks, which may result from less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies. Information about emerging market companies, including financial information, may be less available or reliable and the Adviser’s ability to conduct due diligence with respect to such companies may be limited. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments. In addition, the taxation systems at the federal, regional, and local levels in developing or emerging market countries may be less transparent, inconsistently enforced, and subject to change. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets, and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness, and/or resources than participants in developed markets. |
||
| New/Smaller Sized Fund Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | New/Smaller Sized Fund Risk. Because the Fund is relatively new, it has a limited operating history and a small asset base. The Fund’s performance may not represent how the Fund is expected to or may perform in the long term if and when it becomes larger. If a new or smaller fund were to fail to attract sufficient assets to achieve or maintain economies of scale, performance may be negatively impacted, and any resulting liquidation could create negative transaction costs for the Fund and tax consequences for investors. |
||
| Exchange Listing and Trading Issues Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Exchange Listing and Trading Issues Risk. Although Fund shares are listed for trading on The Nasdaq Stock Market, LLC (the “Exchange”), there can be no assurance that an active trading market for such shares will develop or be maintained. The lack of an active market for Fund shares, as well as periods of high volatility, disruptions in the creation/redemption process, or factors affecting the liquidity of the underlying securities held by the Fund, may result in the Fund’s shares trading at a premium or discount to its NAV. Trading in the Fund’s shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in the Fund’s shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the Fund’s listing will continue to be met or will remain unchanged. |
||
| Fluctuation of NAV and Market Price Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Fluctuation of NAV and Market Price Risk. The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s securities holdings. The market prices of the Fund’s shares will generally fluctuate in accordance with changes in the Fund’s NAV and supply and demand of shares on the Exchange. Volatile market conditions, an absence of trading in shares of the Fund, or a high volume of trading in the Fund, may result in trading prices in the Fund’s shares that differ significantly from the Fund’s NAV. Additionally, during a “flash crash,” the market prices of the Fund’s shares may decline suddenly and significantly resulting in the Fund’s shares trading at a substantial discount to NAV. Such a decline may not reflect the performance of the portfolio securities held by the Fund. Flash crashes may cause Authorized Participants (‘APs”) and other market makers to limit or cease trading in the Fund’s shares for temporary or longer periods, which may result in an increase in the variance between market price of the Fund’s shares and the Fund’s NAV. Shareholders could suffer significant losses to the extent that they sell shares during a flash crash.
It cannot be predicted whether Fund shares will trade below, at, or above the Fund’s NAV. Further, the securities held by the Fund may be traded in markets that close at a different time than the Exchange. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing, or fixing settlement times, bid-ask spreads and the resulting premium or discount to the Fund shares’ NAV is likely to widen. Similarly, the Exchange may be closed at times or days when markets for securities held by the Fund are open, which may increase bid-ask spreads and the resulting premium or discount to the Fund’s shares NAV when the Exchange re-opens. The Fund’s bid-ask spread and the resulting premium or discount to the Fund’s NAV may also be impacted by the liquidity of the underlying securities held by the Fund, particularly in instances of significant volatility of the underlying securities. |
||
| Authorized Participant Risk | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Authorized Participant Risk. The Fund may have a limited number of financial institutions that may act as APs. Only APs who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. These APs have no obligation to submit creation or redemption orders and, as a result, there is no assurance that an active trading market for the Fund’s shares will be established or maintained. This risk may be heightened to the extent that the securities underlying the Fund are traded outside of a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be willing or able to do. In addition, to the extent that APs exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund, and no other AP is able to step forward to create and redeem Creation Units, this may result in a significantly diminished trading market for Fund shares, and Fund shares may be more likely to trade at a premium or discount to the Fund’s NAV and to face trading halts and/or delisting. |

| Risk Lose Money [Member] | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | The biggest risk is that the Fund’s returns and yields will vary, and you could lose money. | ||
| Risk Not Insured Depository Institution [Member] | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. | ||
| Risk Nondiversified Status [Member] | |||
| Prospectus [Line Items] | |||
| Risk [Text Block] | Nondiversification Risk. The Fund is classified as nondiversified under the Investment Company Act of 1940, as amended (the “1940 Act”). This gives the Fund’s portfolio management more flexibility to hold larger positions in securities. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund’s NAV and total return. |
