S000038959 [Member] Investment Risks - Midas Special Opportunities |
Dec. 31, 2025 |
|---|---|
| Industry Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Industry Concentration Risk. The Fund is subject to industry concentration risk, which is the risk that the Fund’s performance can be significantly affected by economic, market, political or regulatory occurrences affecting particular industries. Because the Fund may be concentrated in an industry, its performance may be more volatile than a fund that is not so concentrated. A downturn in a single industry could cause the Fund’s value to decline more sharply than that of the general market.
|
| Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent the Fund focuses its investments, from time to time, in a particular sector, the Fund will be subject to a greater degree to the risks specific to that sector. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single sector, and therefore the Fund, to a greater extent than if the Fund’s investments were diversified across different sectors.
|
| Leverage [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Leverage. The Fund may use leverage to the extent permitted under the 1940 Act. Leveraging (buying securities using borrowed money) exaggerates the effect on the Fund’s NAV of any increase or decrease in the market value of the Fund’s investments. Money the Fund borrows for leveraging is limited to 33 1/3% of the value of the Fund’s total assets. These borrowings are subject to interest costs that may or may not be offset by income or capital gain from the securities purchased. There can be no assurance that the Fund’s use of leverage will be successful.
|
| Foreign Investments [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investments. Investments in the securities of foreign issuers involve certain considerations and risks not ordinarily associated with investments in the securities of domestic issuers. Foreign companies are not generally subject to the same accounting, auditing, and financial standards and requirements as those applicable to U.S. companies. Additionally, there may be less publicly available information about a foreign company than a U.S. company. Investments in foreign securities could expose the Fund to the direct or indirect consequences of political, social, or economic changes in the foreign countries where those securities are issued or in which the issuers are located. With respect to certain foreign countries, there are risks of expropriation, confiscatory taxation, political or social instability, or diplomatic developments that could affect assets of the Fund held in custody in those foreign countries. If the value of any foreign currency in which the Fund’s investments are denominated declines relative to the U.S. dollar, the value of the Fund’s investments is expected to decline proportionately. In addition, a portfolio that includes foreign securities can expect to have a higher expense ratio because of the increased transaction costs on non‑U.S. securities markets and the increased costs of maintaining the custody of foreign securities. The Fund may experience higher levels of each of these risks by investing in emerging (less developed) markets. Further, geopolitical events may cause market disruptions. Ongoing armed conflict in Europe and in the Middle East may cause continued volatility in the securities markets, which could negatively impact the Fund.
|
| Growth Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Growth Securities Risk. The Fund may invest in companies that the Investment Manager believes have growth potential. Securities of companies perceived to be “growth” companies may be more volatile than other securities and may involve special risks. If the Investment Manager’s perception of a company’s growth potential is not realized, the securities purchased may not perform as expected, thereby reducing the Fund’s returns. In addition, because different types of securities tend to shift in and out of favor depending on market and economic conditions, “growth” securities may perform differently from the market as a whole and other types of securities.
|
| Small Capitalization [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small Capitalization. The Fund may invest in companies that are small or thinly capitalized and may have a limited operating history. Investments in small‑cap companies may involve greater risks than investments in larger, more established issuers because they generally are more vulnerable to adverse business or economic developments than stocks of larger companies. The securities of small capitalization companies generally are less liquid and have narrower product lines, more limited financial resources, and more limited markets for their stock as compared with larger companies. As a result, the value of such securities may be more volatile than the securities of larger companies. During broad market downturns, the Fund’s NAV may fall further than those of funds investing in larger companies. Full development of small capitalization companies takes time, and for this reason, among others, the Fund should be considered a long term investment and not a vehicle for seeking short term profit.
|
| Medium and Large Capitalization [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Medium and Large Capitalization. Compared to small capitalization companies, medium and large capitalization companies may be less responsive to business changes and opportunities. At times, the stocks of large capitalization companies may lag other types of stocks in performance. Compared to large capitalization companies, medium capitalization companies may have a shorter history of operations, and may have limited product lines, markets or financial resources.
|
| Pricing [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Pricing. Many factors may influence the price at which the Fund could sell any particular portfolio investment. The sales price may well differ—higher or lower—from the Fund’s last valuation, and such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market conditions make it difficult to value some investments, the Fund may value these investments using more subjective methods, such as fair value pricing. In such cases, the value determined for an investment could be different than the value realized upon such investment’s sale. As a result, you could pay more than the market value when buying Fund shares or receive less than the market value when selling Fund shares.
|
| Security Selection [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Security Selection. The securities selected for the Fund’s portfolio may decline in value. The Investment Manager could be wrong in its analysis of industries, companies, economic trends, the relative attractiveness of different securities, or other matters. As a result, the Fund may underperform the markets, its benchmark index or other funds with the same objective or in the same asset class.
|
| Active Trading [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Active Trading. The Fund may trade securities actively. This strategy could increase transaction costs, reduce performance, and result in increased taxable distributions, which could lower the Fund’s after tax performance.
|
| Short Selling Options and Futures Transactions [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Short Selling, Options, and Futures Transactions. The Fund may engage in short selling, options, and futures transactions to increase returns. There is a risk that these transactions may reduce the Fund’s returns or increase volatility. The Fund may incur a loss as a result of a short position if the price of the asset sold short increases in value between the date of the short position sale and the date on which an offsetting position is purchased, plus any premiums or interest paid to the third party. Because the Fund’s potential loss on a short position arises from increases in the value of the asset sold short, the extent of such loss, like the price of the asset sold short, is theoretically unlimited. In addition, derivatives, such as options and futures, can be illiquid and highly sensitive to changes in their underlying security, interest rate or index, and as a result can be highly volatile. Derivatives also may be subject to certain other risks such as leverage risk, liquidity risk, interest rate risk, market risk, credit risk, the risk that a counterparty may be unable or unwilling to honor its obligations, management risk and the risk of mispricing or improper valuation. A small investment in certain derivatives could have a potentially large impact on the Fund’s performance.
|
| Cybersecurity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Cybersecurity Risk. With the Internet and other technologies being essential to conducting business, the Fund is susceptible to operational, information security, and related risks. The growing use of artificial intelligence may lead to increasingly sophisticated cybersecurity attacks. Cyber incidents affecting the Fund or its service providers, including incidents involving artificial intelligence, 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 related costs.
|
| Recent Market Events [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Recent Market Events. U.S. and international markets have experienced volatility in recent months and years due to a number of economic, political and global macro factors, including elevated inflation levels and wars in Europe and in the Middle East. Uncertainties regarding interest rate levels, political events, potential trade restrictions and tariffs, global geopolitical conflicts, and the possibility of a national or global recession have also contributed to market volatility.
|
| Market Risks [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. The market risks associated with investing in the Fund are those related to fluctuations in the value of the investments in the Fund’s portfolio. A risk of investing in stocks and other instruments is that their value will go up and down, sometimes rapidly and unpredictably, reflecting overall economic conditions and other factors and you could lose money. The Fund may invest in emerging companies, such as start‑ups and spin-offs, and special situations, which include companies undergoing unusual or possibly one time developments such as reorganizations or liquidations. These investments may involve above average market price volatility and greater risk of loss. Certain unanticipated events, such as natural disasters, terrorism, war, and other geopolitical events, can have a dramatic adverse effect on the investments held by the Fund.
|
| Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | It is not a complete investment program and you could lose money by investing in the Fund. |
| Risk Not Insured Depository Institution [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. |
| Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non‑Diversification. The Fund is non‑diversified, which means that it is not limited by the 1940 Act in the proportion of its assets that may be invested in the securities or obligations of a single issuer. As a result, the Fund may hold a smaller number of issuers than if it were diversified. Investing in a non‑diversified fund could involve more risk than investing in a fund that holds a broader range of securities because changes in the financial condition of a single issuer could cause greater fluctuation in the Fund’s total returns.
