The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example of Expenses, affect the Fund’s performance. During the most recent fiscal year, the portfolio turnover rate was 118% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in various credit-related instruments. “Credit-related instruments” are debt securities, instruments and obligations of U.S. and non-U.S. governments, non-governmental and corporate entities and issuers, and include (i) debt issued by or on behalf of states, territories, and possessions of the United States, (ii) U.S. and non-U.S. corporate bonds, notes and other debentures, (iii) securities issued or guaranteed by the U.S. government, its agencies, instrumentalities or sponsored entities, (iv) sovereign debt, including emerging markets debt (v) zero coupon securities, (vi) collateralized debt and loan obligations, (vii) senior secured floating rate and fixed rate loans or debt, (viii) second lien or other subordinated or unsecured floating rate and fixed rate loans or debt, and (ix) derivatives with similar economic characteristics. The Fund may invest up to 100% of its net assets in any one of the categories of instruments included in the preceding sentence. The Fund may invest its total assets, including borrowings for investment purposes and proceeds from short selling, if any, without restriction in debt securities of any maturity and credit quality, including securities that are rated at the time of investment below investment grade (that is, securities rated below the Baa3/BBB- categories by nationally recognized securities rating organizations or, if unrated, determined to be of comparable quality by Shelton), commonly referred to as “junk bonds.”

The Fund is managed as a total return fund, employing a “credit long/short” investment strategy. Shelton makes assessments across the fixed income markets that include analyses of asset classes, economic sectors, individual credits, and security selection in order to identify undervalued securities and overlooked market opportunities, as well as to attempt to take advantage of certain arbitrage opportunities. The Fund’s short positions may equal up to 100% of the Fund’s net asset value. The Fund may take short positions in U.S. Treasuries, treasury futures, corporate bonds, credit default and/or interest rate swaps, exchange-traded funds (“ETFs”), non-U.S. bonds, equities and equity-related instruments, and options. The Fund’s investment strategy involves active and frequent trading.

The Fund may also engage in borrowing for cash management purposes or for investment purposes, in order to increase its holdings of portfolio securities and/or to collateralize short sale positions. The Fund may use ETFs and derivatives, such as options, futures contracts, forward currency contracts and swap agreements (including, but not limited to, interest rate swaps, credit default swaps and total return swaps), both for hedging purposes and to seek investment returns consistent with the Fund’s investment objective.

Summary of Principal Risks of Investing

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Risk is inherent in all investing and you could lose money by investing in the Fund. A summary description of certain principal risks of investing in the Fund is set forth below. Before you decide whether to invest in the Fund, carefully consider these risk factors associated with investing in the Fund, which may cause investors to lose money. There can be no assurance that the Fund will achieve its investment objective.

Market Risk. Investment prices may increase or decrease, sometimes suddenly and unpredictably, due to general market conditions. The Fund invests in stock markets primarily outside the U.S. As with any investment whose performance is linked to these markets, the value of an investment in the Fund will change. During a declining stock market, investment in this Fund would lose money.

Interest Rate Risk. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, with longer-term securities being more sensitive than shorter-term securities. For example, the price of a security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Generally, the longer the maturity and duration of a bond or fixed rate loan, the more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund’s income. Changes in governmental policy, rising inflation rates, and general economic developments, among other factors, could cause interest rates to increase and could have a substantial and immediate effect on the values of the Fund’s investments. These risks are greater during periods of rising inflation. In addition, a potential rise in interest rates may result in periods of volatility and increased redemptions that might require the Fund to liquidate portfolio securities at disadvantageous prices and times.

Fixed Income Securities Risk. The prices of fixed income securities respond to economic developments, particularly interest rate changes, as well as to changes in an issuer’s credit rating or market perceptions about the creditworthiness of an issuer. Generally fixed income securities decrease in value if interest rates rise and increase in value if interest rates fall, and longer-term and lower rated securities are more volatile than shorter-term and higher rated securities.

Derivatives Risk. Derivatives include instruments and contracts that are based on and valued in relation to one or more underlying securities, financial benchmarks, indices, or other reference obligations or measures of value. Major types of derivatives include futures, options, swaps and forward contracts. Using derivatives can have a leveraging effect and increase fund volatility. Derivatives transactions can be highly illiquid and difficult to unwind or value, and changes in the value of a derivative held by the Fund may not correlate with the value of the underlying instrument or the Fund’s other investments. Many of the risks applicable to trading the instruments underlying derivatives are also applicable to derivatives trading. However, additional risks are associated with derivatives trading that are possibly greater than the risks associated with investing directly in the underlying instruments. These additional risks include, but are not limited to, illiquidity risk, and counterparty credit risk. For derivatives that are required to be cleared by a regulated clearinghouse, other risks may arise from the Fund’s relationship with a brokerage firm through which it submits derivatives trades for clearing, including in some cases from other clearing customers of the brokerage firm.

Municipal Bond Risk. Interest rates on tax-exempt municipal bonds are generally lower than taxable bonds, and the return on investment in the Fund may be lower than an investment in another fund that does not invest in tax-exempt municipal obligations. The Funds generally will not be eligible to pass-through to their shareholders the tax-exempt character of municipal bond interest. Changes or proposed changes in federal tax laws could impact the value of the debt securities of municipal issuers that the Fund may purchase. Also, the failure or possible failure of such debt issuances to qualify for tax-exempt treatment may cause the prices of such municipal securities to decline, possibly adversely affecting the value of the Fund’s portfolio, and such a failure could also result in additional taxable income to the Fund and its shareholders. The value of municipal securities can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or credit enhancement providers for municipal issuers, regulatory and political developments, legislative actions, and by uncertainties and public perceptions concerning these and other factors. Financial difficulties impacting certain municipal issuers could result in an increasing number of defaults on obligations by municipal issuers.

Credit Risk. If an issuer or guarantor of a debt security held by the Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Fund’s portfolio will typically decline. Subordinated securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness.

Prepayment or Call Risk. Many issuers have a right to prepay their securities. If interest rates fall, an issuer may exercise this right. If this happens, the Fund will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on the prepaid security. The Fund may also lose any premium it paid on the security.

High Yield (“Junk”) Bond Risk. High yield bonds are debt securities rated below investment grade (often called “junk bonds”). Junk bonds are speculative, involve greater risks of default, downgrade, or price declines and are more volatile and tend to be less liquid than investment- grade securities. Companies issuing high yield bonds are less financially strong, are more likely to encounter financial difficulties, and are more vulnerable to adverse market events and negative sentiments than companies with higher credit ratings.

Asset Segregation Risk. As a series of an investment company registered with the SEC, the Fund must segregate liquid assets, or engage in other measures to “cover” open positions with respect to certain kinds of derivatives and short sales. The Fund may incur losses on derivatives and other leveraged investments (including the entire amount of the Fund’s investment in such investments) even if they are covered.

Borrowing Risk. Borrowing may exaggerate changes in the net asset value of Fund shares and in the return on the Fund’s portfolio. Borrowing will cost the Fund interest expense and other fees. The costs of borrowing may reduce the Fund’s return. Borrowing may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations.

Collateralized Debt Obligations Risk. Collateralized debt obligations are subject to credit, interest rate, valuation, prepayment and extension risks. These securities also are subject to risk of default on the underlying asset, particularly during periods of economic downturn.

Currency Risk. The values of investments in securities denominated in foreign currencies increase or decrease as the rates of exchange between those currencies and the U.S. Dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation.

Extension Risk. If interest rates rise, repayments of fixed income securities may occur more slowly than anticipated by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they remain outstanding longer.

Non-U.S. Investment Risk. Securities of non-U.S. issuers (including ADRs and other securities that represent interests in a non-U.S. issuer’s securities) may be less liquid, more volatile, and harder to value than U.S. securities. Non-U.S. issuers may be subject to political, economic, or market instability, or unfavorable government action in their local jurisdictions or economic sanctions or other restrictions imposed by U.S. or foreign regulators. There may be less information publicly available about non-U.S. issuers and their securities and those issuers may be subject to lower levels of government regulation and oversight. These risks may be higher when investing in emerging market issuers. Certain of these elevated risks may also apply to securities of U.S. issuers with significant non-U.S. operations.

Foreign Sovereign Risk. Foreign governments rely on taxes and other revenue sources to pay interest and principal on their debt obligations. The payment of principal and interest on these obligations may be adversely affected by a variety of factors, including economic results within the foreign country, changes in interest and exchange rates, changes in debt ratings, changing political sentiments, legislation, policy changes, a limited tax base or limited revenue sources, natural disasters, or other economic or credit problems.

Leveraging Risk. Certain Fund transactions, including entering into futures contracts and taking short positions in financial instruments, may give rise to a form of leverage. Leverage can magnify the effects of changes in the value of the Fund’s investments and make the Fund more volatile. Leverage creates a risk of loss of value on a larger pool of assets than the Fund would otherwise have had, potentially resulting in the loss of all assets. The Fund may also have to sell assets at inopportune times to satisfy its obligations in connection with such transactions.

Liquidity Risk. The Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. In addition, the reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years has the potential to decrease the liquidity of the Fund’s investments. Illiquid assets may also be difficult to value.

Short Sales Risk. In connection with a short sale of a security or other instrument, the Fund is subject to the risk that instead of declining, the price of the security or other instrument sold short will rise. If the price of the security or other instrument sold short increases between the date of the short sale and the date on which the Fund replaces the security or other instrument borrowed to make the short sale, the Fund will experience a loss, which is theoretically unlimited since there is a theoretically unlimited potential for the market price of a security or other instrument sold short to increase. Shorting options or futures may have an imperfect correlation to the assets held by the Fund and may not adequately protect against losses in or may result in greater losses for the Fund’s portfolio.

Sector Concentration Risk. The Fund may concentrate its investments in companies that are in a single sector or related sector. Concentrating investments in a single sector may make the Fund more susceptible to adverse economic, business, regulatory or other developments affecting that sector. If an economic downturn occurs in a sector in which the Fund’s investments are concentrated, the Fund may perform poorly during that period.

ETF Risk. Investing in an ETF will provide the Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Manager Risk. Shelton Capital Management’s opinion about the intrinsic worth or creditworthiness of a company or security may be incorrect or the market may continue to undervalue the company or security. Shelton Capital Management may not make timely purchases or sales of securities for the Fund.

Portfolio Turnover Risk: The risk that high portfolio turnover is likely to lead to increased Fund expenses that may result in lower investment returns. High portfolio turnover also is likely to result in higher short-term capital gains taxable to shareholders.

COVID-19 Risks. The impact of COVID-19, (and the variants of such virus) and other epidemics and pandemics that may arise in the future, could affect the economies of many nations, individual companies, their securities (including equity and debt), and the market in general in ways that cannot necessarily be foreseen at the present time. Health crises caused by the recent coronavirus outbreak may exacerbate other pre-existing political, social, financial, and economic risks in certain countries. The impact of the outbreak may last for an extended period of time.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund primarily invests, under normal market conditions, at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in a combination of equity securities of foreign (i.e., non-U.S.) companies with a suitable potential for earnings growth. The Fund invests its assets in equity securities of non-U.S. companies located in countries with developed markets but may also invest in companies domiciled in emerging markets.

Under normal market conditions, the Fund seeks to achieve its investment objective by investing in a universe of stocks listed within the MSCI ACWI ex USA index, as well as those in other developed, emerging, and frontier markets with a market capitalization of $2.5 billion or higher. The Advisor anticipates that the percentage of the Fund’s investable universe not included in the MSCI ACWI ex USA index will be approximately 20%. The Fund ordinarily invests in no fewer than three different countries outside the U.S. The Fund may invest a lesser amount of its assets in securities of non-U.S. companies when market conditions are not deemed favorable, in which case the Fund would invest at least 30% of its net assets, plus any borrowings for investment purposes, in securities of non-U.S. companies. The Fund will normally invest in the securities of approximately 30 to 50 issuers.

The Fund’s investments in equity securities may include common and preferred stock, convertible preferred stock, warrants and rights. Additionally, in unusual or extreme market conditions, the manager may choose to hedge general market exposures. This may be done primarily with the use of certain ETF’s that create either long or short exposure to the desired market segment.

The Fund’s investments are based on a principles-based investment philosophy, and the Fund seeks to invest in businesses it believes are overall beneficial to society, and in the first instance considers potential investments on that basis. Our criteria for such businesses are that they offer products and services that improve the lives of their customers, and of people in the communities in which they operate, and to exhibit responsible management practices. These practices may include dealings with customers, suppliers, employees, and the environment. Additionally, special care is taken when investing in companies in countries that have controversial governments and may involve the avoidance of some industries in certain countries or some countries altogether. There is no guarantee that the investment team will be able to successfully screen out all companies that are inconsistent with its ethical standards.

With this perspective in mind, we apply a three-stage investment process to construct a portfolio with consistent returns with an appropriate level of risk.

Classification: The team classifies companies in our investment universe according to different characteristics: what industry they belong to, where they are in their life-cycle, and what part of the world they are from. This classification guides the analysis of each company, focusing on the aspects of a company most relevant to future performance

Analysis: With these qualities in mind the team uses data science and machine learning to conduct a deeper dive into each candidate firm to determine the investment merit, suitability for the portfolio, and pertinent risk factors.

Portfolio Construction: We view the portfolio as a whole, adjusting, including or excluding positions in order to provide the greatest exposure to stocks with sustainable performance, while minimizing exposure to systematic risks such as interest rates, currency rate volatility, or the economic cycle.

The Fund may invest in equity index futures contracts when holding cash or cash equivalents to keep the Fund more fully exposed to the equity markets.

The Fund may engage in frequent and active trading of securities as a part of its principal investment strategy. The Advisor may sell or reallocate a Fund’s securities if the Advisor believes the issuer of such securities no longer meets certain growth criteria, if certain political and economic events occur, or if it believes that more attractive opportunities are available. The team strives to preserve capital as part of its investment process.

Summary of Principal Risks of Investing

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund, and the Fund could underperform other investments. You should expect the Fund’s share price and total return to fluctuate within a wide range. The Fund’s performance could be hurt by:

Economic and Political Risks. These effects may be short-term by causing a change in the global markets that is corrected in a year or less, or they may have long-term impacts which may cause changes in the markets that may last for many years. In any given country, some factors may affect changes in one sector of the economy or one stock, but don’t have an impact on the overall market. The particular sector of the economy or the individual stock may be affected for a short or long-term.

Equity Risk. Equity securities can be volatile and may decline in value because of changes in the actual or perceived financial condition of their issuers or other events affecting their issuers. The Fund’s target index may, at times, become focused in stocks of a particular sector, category or group of companies, which could cause Fund to underperform the overall stock market.

Non-U.S. Currency Risk. Non-U.S. currencies may decline relative to the U.S. dollar, which reduces the unhedged value of securities denominated in or otherwise exposed to those currencies. Shelton Capital Management may not be able to determine accurately the extent to which a security or its issuer is exposed to currency risk.

Portfolio Turnover Risk: The risk that high portfolio turnover is likely to lead to increased Fund expenses that may result in lower investment returns. High portfolio turnover also is likely to result in higher short-term capital gains taxable to shareholders.

Valuation Risk: The risk that the Fund has valued certain of its securities at a higher price than it can sell them. Some or all of the securities held by the Fund may be valued using “fair value” techniques, rather than market quotations. Security values may differ depending on the methodology used to determine their values, and may differ from the last quoted sales or closing prices.

MidCap Stock Risk. The risk that stocks of relatively smaller capitalization within the midcap range of companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Relatively smaller capitalization companies may have limited product lines or financial resources, or may be dependent upon a small or inexperienced management group, and their securities may trade less frequently and in lower volume than the securities of larger companies, which could lead to higher transaction costs. Generally, the smaller the company size, the greater the risk.

SmallCap Stock Risk. The risk that stocks of smaller capitalization companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Small capitalization companies may have limited product lines or financial resources, or may be dependent upon a small or inexperienced management group, and their securities may trade less frequently and in lower volume than the securities of larger companies, which could lead to higher transaction costs. Generally, the smaller the company size, the greater the risk.

ETF Risk. In unusual or extreme market conditions, the manager may choose to hedge general market exposures. This may be done primarily with the use of certain ETF’s that create either long or short exposure to the desired market segment. Investing in an ETF will provide the Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Ethical Investment Risk. In avoiding investments that are inconsistent with the Fund’s principles based screening approach, which may preclude an otherwise attractive investment opportunity, the Fund may not achieve the same level of performance as it would have without the application of the screening process.

Derivatives Risk. Investing with derivatives, such as equity index futures, or other futures contracts involves risks additional to and possibly greater than those associated with investing directly in securities. The value of a derivative may not correlate to the value of the underlying instrument to the extent expected. Derivative transactions may be volatile, and can create leverage, which could cause the Fund to lose more than the amount of assets initially contributed to the transaction, if any. The Fund may not be able to close a derivatives position at an advantageous time or price. For over-the-counter derivatives transactions, the counterparty may be unable or unwilling to make required payments and deliveries, especially during times of financial market distress. Changes in regulation relating to a mutual fund’s use of derivatives and related instruments may make derivatives more costly, limit the availability of derivatives, or otherwise adversely affect the value or performance of derivatives and the Fund.

Manager Risk. Shelton Capital Management’s opinion about the intrinsic worth or creditworthiness of a company or security may be incorrect or the market may continue to undervalue the company or security. Shelton may not make timely purchases or sales of securities for the Fund.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund primarily invests, under normal market conditions, at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in a combination of equity securities of foreign (i.e., non-U.S.) companies in “Emerging Markets” with a suitable potential for earnings growth. “Emerging markets” for this purpose are markets included in MSCI Emerging Markets Index (the “Index”). The Fund invests its assets in equity securities of non-U.S. companies located in countries with emerging markets, but may also invest in companies domiciled in developed markets.

Under normal market conditions, the Fund seeks to achieve its investment objective by investing primarily in a universe of stocks listed within the MSCI Emerging Markets Index. In determining whether an issuer not included in the Index is within the geographies represented as emerging markets by the Index, the Advisor may consider the domicile determination of a leading provider of global indexes, such as Morgan Stanley Capital International, and may also take into account such factors as where the company’s securities are listed and where the company is legally organized, maintains principal corporate offices, conducts its principal operations and/or generates revenues. The Fund will normally invest in the securities of approximately 30 to 50 issuers.

With this perspective in mind, we apply a three-stage investment process to construct a portfolio with consistent returns with an appropriate level of risk.

The Fund may invest in equity index futures contracts when holding cash or cash equivalents to keep the Fund more fully exposed to the equity markets.

The Fund may engage in frequent and active trading of securities as a part of its principal investment strategy. The Advisor will sell or reallocate a Fund’s securities if the Advisor believes the issuer of such securities no longer meets certain growth criteria, if certain political and economic events occur, or if it believes that more attractive opportunities are available. The team strives to preserve capital as part of its investment process.

Summary of Principal Risks of Investing

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Emerging Markets Risk. Emerging market securities may present issuer, market, currency, liquidity, volatility, valuation, legal, political, and other risks different from, and potentially greater than, the risks of investing in securities of issuers in more developed markets. Emerging markets may have less established legal and accounting systems than those in more developed markets. Governments in emerging markets may be less stable and more likely to take extra-legal action with respect to companies, industries, assets, or foreign ownership than those in more developed markets. The economies of emerging markets may be dependent on relatively few industries and thus affected more severely by local or global changes. Emerging market securities may also be more volatile, more difficult to value, and have lower overall liquidity than securities economically tied to U.S. or developed non-U.S. issuer.

Non-U.S. Investment Risk. Securities of non-U.S. issuers (including American depository receipts (“ADRs”) and other securities that represent interests in a non-U.S. issuer’s securities) may be less liquid, more volatile, and harder to value than U.S. securities. Non-U.S. issuers may be subject to political, economic, or market instability, or unfavorable government action in their local jurisdictions or economic sanctions or other restrictions imposed by U.S. or foreign regulators. There may be less information publicly available about non-U.S. issuers and their securities and those issuers may be subject to lower levels of government regulation and oversight. These risks may be higher when investing in emerging market issuers. Certain of these elevated risks may also apply to securities of U.S. issuers with significant non-U.S. operations.

Equity Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, national or international political events, natural disasters, the spread of infectious illness or other public health issue, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally.

MidCap Stock Risk. The risk that stocks of relatively smaller capitalization within the midcap range of companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Relatively smaller capitalization companies may have limited product lines or financial resources or may be dependent upon a small or inexperienced management group, and their securities may trade less frequently and in lower volume than the securities of larger companies, which could lead to higher transaction costs. Generally, the smaller the company size, the greater the risk.

SmallCap Stock Risk. The risk that stocks of smaller capitalization companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Small capitalization companies may have limited product lines or financial resources or may be dependent upon a small or inexperienced management group, and their securities may trade less frequently and in lower volume than the securities of larger companies, which could lead to higher transaction costs. Generally, the smaller the company size, the greater the risk.

Valuation Risk: The risk that the Fund has valued certain of its securities at a higher price than it can sell them. Some or all of the securities held by the Fund may be valued using “fair value” techniques, rather than market quotations. Security values may differ depending on the methodology used to determine their values and may differ from the last quoted sales or closing prices.

Ethical Investment Risk. In avoiding investments that are inconsistent with the Fund’s principles based screening approach, which may preclude an otherwise attractive investment opportunity, the Fund may not achieve the same level of performance as it would have without the application of the screening process.

Derivatives Risk. Investing with derivatives, such as equity index futures, or other futures contracts involves risks additional to and possibly greater than those associated with investing directly in securities. The value of a derivative may not correlate to the value of the underlying instrument to the extent expected. Derivative transactions may be volatile, and can create leverage, which could cause the Fund to lose more than the amount of assets initially contributed to the transaction, if any. The Fund may not be able to close a derivatives position at an advantageous time or price. For over-the-counter derivatives transactions, the counterparty may be unable or unwilling to make required payments and deliveries, especially during times of financial market distress. Changes in regulation relating to a mutual fund’s use of derivatives and related instruments may make derivatives more costly, limit the availability of derivatives, or otherwise adversely affect the value or performance of derivatives and the Fund.

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

Shelton Capital Management has contractually agreed to reimburse expenses incurred by the Fund to the extent that total annual fund operating expenses (excluding acquired fund fees and expenses, certain compliance costs, and extraordinary expenses such as litigation or merger and reorganization expenses, for example) exceed 0.99% and 1.24% for Institutional Class and Investor Class shares, respectively, until May 1, 2023. This agreement may only be terminated with the approval of the SCM Trust Board. Shelton may be reimbursed for any foregone advisory fees or unreimbursed expenses within three fiscal years following a particular reduction or expense, but only to the extent the reimbursement does not cause the Fund to exceed applicable expense limits, and the effect of the reimbursement is measured after all ordinary operating expenses are calculated. Any such reimbursement is subject to the review and approval of the SCM Trust Board.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund uses a quantitative methodology to identify securities ICON believes are underpriced relative to value. The Fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies of any market capitalization, including convertible and preferred securities, and in securities issued by dividend-paying companies. This strategy may not be changed unless Fund shareholders are given at least 60 days prior notice. To manage the risk of holding equity securities, the Fund may write call options or purchase put options on securities or securities indexes.

The Fund may invest up to 25% of its assets in a single industry. The Fund may also invest in U.S. government agencies or government sponsored enterprises and investment-grade securities, although the Fund may invest up to 25% of its total assets in securities with a lower rating by both S&P and Moodys.

ICON’s quantitative methodology calculates intrinsic value using average earnings per share, future earnings growth estimates, beta, and bond yield. This calculated intrinsic value for each individual stock is aggregated by industry and sector which enables ICON to identify value opportunities within industries and sectors. ICON then employs a tactical, rotation-based process that tilts the Fund toward industries and sectors ICON believes will outperform.

ICON believes that equity markets go through themes over time, simply stated, stocks in industries that were market leaders at one time tend to become overpriced relative to intrinsic value, and stocks in industries that were not in favor tend to drop below intrinsic value. In general, the Fund will sell securities in industries ICON believes are overpriced and buy securities in industries we believe are underpriced. We believe ICON’s combination of industry rotation and bottom-up valuation distinguishes us from other investment managers.

The Fund will not change its principal investment strategy without providing shareholders at least 60 days’ notice.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Like all investments in securities, you risk losing money by investing in the Fund. The main risks of investing in this Fund are:

Industry and Concentration Risk. Companies that have similar lines of business are grouped together in broad categories called industries. Certain industries are grouped together in broad categories called sectors. The Fund may overweight industries within various sectors and may invest up to 25% of the Fund’s total assets in a single industry. The fact that the Fund may overweight a specific industry or industries may cause the Fund’s performance to be more susceptible to political, economic, business or other developments that affect those industries or sectors. This overweighting means the Fund may be less diverse and more volatile than its benchmark.

Small and Mid-Size Company Risk. The Fund may invest in small or mid-size companies which in turn may involve greater risk of loss and price fluctuation. The trading markets for securities of small-cap issuers may be less liquid and more volatile than securities of larger companies.

Investment in Other Investment Companies Risk. The Fund may invest in other investment companies. As with other investments, investments in other investment companies, including closed-end funds (which include business development companies (“BDCs”), unit investment trusts, open-end investment companies, and exchange traded funds, are subject to many of the same risks as investing directly in the underlying instruments, including market risk and, for non-index strategies, selection risk. In addition, if the Fund acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Fund (including management and advisory fees) and, indirectly, the expenses of the investment companies (including management and advisory fees). If the Fund acquires shares of one or more underlying funds, shareholders bear both their proportionate share of expenses in the Fund (excluding management and advisory fees attributable to those assets of the Fund invested in the underlying funds) and, indirectly, the expenses of the underlying funds (including management and advisory fees). Further, the closed-end fund market is inefficient. Many closed-end funds (“CEFs”), including many in which the Fund invests, are small or micro-cap securities. There is little independent research published on CEFs and limited availability of data makes research difficult and time consuming. CEFs may trade unpredictably. The underlying assets may be unknown and their value not readily determinable. The Fund often purchases CEFs believing they are trading at a discount to NAV, and an ongoing corporate action will cause the discount to narrow or disappear. With little independent analysis of the CEFs’ individual assets, the Fund essentially makes a value based arbitrage strategy. The Fund will look to events like pending or proposed tender offers, liquidations, take-over plays etc. If the event is not preceded by an official announcement — and is, instead, “pending” or “anticipated” — this strategy can be very risky. If the event is announced, there is still the possibility that it will not happen. In sum, investing in CEFs in general, and CEF arbitrage plays in particular carry unique and arguably heightened risks.

Credit Risk. The Fund could lose money if the issuer of a fixed income security is unable to meet its financial obligations or goes bankrupt. Failure of an issuer to make timely payments of principal and interest or a decline or perception of decline in the credit quality of a fixed income security can cause a security’s price to fall, potentially affecting the Fund’s share price. Furthermore, the Fund invests primarily in corporate bonds, which are not guaranteed by the U.S. government. If the corporate issuer or guarantor of a debt security is unable or unwilling to honor its obligations, the government will not intervene if the issuer defaults and the Fund will lose its investment in the issue.

Changes in Debt Ratings. If a rating agency gives a convertible security a lower rating, the value of the security may decline because investors will demand a higher rate of return.

Bond Risk. Bond prices tend to move inversely with changes in interest rates. Bonds with longer maturities are more sensitive to changes in interest rates. Slower payoffs effectively increase duration, also heightening interest rate risk. The Fund could lose money if the issuer of the bonds is unable to meet its financial obligations or goes bankrupt. Failure of an issuer to make timely payments of principal or interest, or a decline in the perception in the credit quality of a bond could affect bond prices. If a credit rating agency gives a debt security a lower rating, the value or liquidity of the bond may be adversely affected. Bonds, unlike equities listed on a national securities exchange, have less liquidity and the Fund may not be able to sell the bonds when it wants to sell, or if it can, it may need to sell at greatly reduced prices because of the lack of demand.

High Yield Risk. The Fund may invest 25% of its net assets in high yield securities (commonly known as “junk bonds”) which may be subject to greater levels of interest rate, credit and liquidity risk than investment grade securities. High yield securities may be considered speculative with respect to the issuer’s continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for junk bonds and reduce the Fund’s ability to sell these securities (liquidity risk). If the issuer of a security is in default with respect to interest or principal payments, the Fund may lose its investment in the issue.

Options Risk. Investments in options involve certain risks. These risks include:

● Limited Gains. By selling a call option, the Fund may forego the opportunity to benefit from an increase in price of the underlying stock or index above the exercise price, but continue to bear the risk of a decline in the value of the underlying stock or index. While the Fund receives a premium for writing the call option, the price the Fund realizes from the sale of stock or exposure to the underlying index upon exercise of the option could be substantially below its prevailing market price.

●

Premium Losses. By purchasing a put option for a premium, the Fund secures the right to sell a security to the writer of that option on or before a fixed date at a predetermined price. The Fund will realize a gain from the exercise of a put option if, during the option period, the price of the security declines by an amount in excess of the premium paid. The Fund will realize a loss equal to all or a portion of the premium paid for the option if the price of the security increases or does not decrease by more than the premium.

●

Lack of Liquidity for the Option. A liquid market may not exist for the option. If the Fund is not able to close out the options transaction, the Fund will not be able to sell the underlying security until the option expires or is exercised.

●

Lack of Liquidity for the Security. The Fund’s investment strategy may also result in a lack of liquidity of the purchase and sale of portfolio securities. Because the Fund may generally hold the stocks or exposure to the index underlying the option, the Fund may be less likely to sell the stocks in its portfolio to take advantage of new investment opportunities. This risk is less likely to be prevalent on options that are written on an index.

Tax Consequences. The sale of call options generates premiums. These premiums typically will result in ordinary income or short-term capital gains to the Fund for federal and state income tax purposes. Transactions involving the disposition of the Fund’s underlying securities (whether pursuant to the exercise of a call option or otherwise) will give rise to capital gains or losses. Due to the tax treatment of securities on which call options have been written, the majority, if not all, of the gains from the sale of the underlying security will be short-term capital gains. Short-term capital gains are taxable as ordinary income when distributed to shareholders. Because the Fund does not have control over the exercise of the call options it writes, shareholder redemptions or corporate events involving its equity securities investments (such as mergers, acquisitions or reorganizations), may force it to realize capital gains or losses at inopportune times. The Fund intends to make quarterly distributions of income (versus capital gains), if any.

Portfolio Turnover Risk. Active trading generates transaction costs which, in turn, can affect performance. A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses, affect the Fund’s performance.

Quantitative Model Risk. Quantitative models and the analysis of specific metrics are used to construct the Fund’s portfolio. The impact of these metrics on a stock’s performance can be difficult to predict, and stocks that previously possessed certain desirable quantitative characteristics may not continue to demonstrate those same characteristics in the future. In addition, relying on quantitative models entails the risk that the models themselves may be limited or incorrect, that the data on which the models rely may be incorrect or incomplete, and that ICON Advisers may not be successful in selecting companies for investment or determining the weighting of particular stocks in the Fund’s portfolio. Any of these factors could cause the Fund to underperform funds with similar strategies that do not select stocks based on quantitative analysis.

Manager Risk. ICON Advisers’ opinion about the intrinsic worth or creditworthiness of a company or security may be incorrect or the market may continue to undervalue the company or security. ICON Advisers may not make timely purchases or sales of securities for the Fund.

Interest Rate Risk. Prices of convertible securities tend to move inversely with changes in interest rates. For example, when interest rates rise, prices of convertible securities generally fall. Securities with longer maturities tend to be more sensitive to changes in interest rates. Due to their hybrid nature, convertible securities are typically more sensitive to changes in interest rates than the underlying common stock, but less sensitive to interest rate changes than a fixed-rate corporate bond.

COVID-19 Risks. The impact of COVID-19, (and the variants of such virus) and other epidemics and pandemics that may arise in the future, could affect the economies of many nations, individual companies, their securities (including equity and debt), and the market in general in ways that cannot necessarily be foreseen at the present time. Health crises caused by the recent coronavirus outbreak may exacerbate other pre-existing political, social, financial, and economic risks in certain countries. The impact of the outbreak may last for an extended period of time.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund uses a valuation methodology to identify securities ICON Advisors, Inc. ("ICON"), the Fund’s investment sub-advisor, believes are underpriced relative to value. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in a broad range of U.S. dollar-denominated fixed income products. These include corporate bonds, notes and debentures, and closed-end funds that invest at least 80% of their assets in fixed income securities, as well as U.S. government and agency securities. This strategy may not be changed unless Fund shareholders are given at least 60 days prior notice. The Fund generally invests in investment-grade securities, although the Fund may invest up to 35% of its assets in securities with a lower rating by both S&P and Moody’s. There is no limit on the Fund’s average maturity or on the maturity of any individual issues in the Fund.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Like all investments in securities, you risk losing money by investing in the Fund. The main risks of investing in this Fund are:

High Yield Risk. The Fund may invest up to 35% of the Fund’s total assets in high yield securities (commonly known as “junk bonds”) which may be subject to greater levels of interest rate, credit and liquidity risk than investment grade securities. These securities may be considered speculative with respect to the issuer’s continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for junk bonds and reduce the Fund’s ability to sell these securities (liquidity risk). If the issuer of a security is in default with respect to interest or principal payments, the Fund may lose its investment in the issue.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. The Fund’s investment in less liquid securities may reduce the Fund’s returns because it may be unable to sell the less liquid security at an advantageous time or price.

Interest Rate Risk. Bond prices tend to move inversely with changes in interest rates. For example, when interest rates rise, bond prices generally fall. Securities with longer maturities are more sensitive to changes in interest rates. Performance could also be affected if unexpected interest rate trends cause the Fund’s mortgage or asset-backed securities to be paid off substantially earlier or later than expected. Slower payoffs effectively increase maturity, also heightening interest rate risk. When interest rates fall, many mortgages are refinanced and mortgage-backed securities may be repaid early. As a result, the Fund may not experience the increase in market value from these securities that normally accompanies a decline in interest rates.

Investment in Other Investment Companies Risk. The Funds may invest in other investment companies. As with other investments, investments in other investment companies, including closed-end funds (which include business development companies (BDCs), unit investment trusts, open-end investment companies, and exchange traded funds, are subject to many of the same risks as investing directly in the underlying instruments, including market risk and, for non-index strategies, selection risk. In addition, if the Fund acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Fund (including management and advisory fees) and, indirectly, the expenses of the investment companies (including management and advisory fees). If the Fund acquires shares of one or more underlying funds, shareholders bear both their proportionate share of expenses in the Fund (excluding management and advisory fees attributable to those assets of the Fund invested in the underlying funds) and, indirectly, the expenses of the underlying funds (including management and advisory fees). Further, the closed-end fund market is inefficient. Many closed-end funds (CEFs), including many in which the Fund invests, are small or micro-cap securities. There is little independent research published on CEFs and limited availability of data makes research difficult and time consuming. CEFs may trade unpredictably. The underlying assets may be unknown and their value not readily determinable. The Fund often purchases CEFs believing they are trading at a discount to NAV, and an ongoing corporate action will cause the discount to narrow or disappear. With little independent analysis of the CEFs’ individual assets, the Fund essentially makes a value based arbitrage strategy. The Fund will look to events like pending or proposed tender offers, liquidations, take-over plays etc. If the event is not preceded by an official announcement — and is, instead, “pending” or “anticipated” — this strategy can be very risky. If the event is announced, there is still the possibility that it will not happen. In sum, investing in CEFs in general, and CEF arbitrage plays in particular carry unique and arguably heightened risks.

Changes in Debt Ratings. If a rating agency gives a debt security a lower rating, the value of the security may decline because investors may demand a higher rate of return.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund uses a quantitative methodology to identify securities ICON Advisors, Inc. (“ICON”) the Fund’s investment sub-advisor, believes are underpriced relative to value. Normally the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities traded in the U.S. This strategy may not be changed unless Fund shareholders are given at least 60 days prior notice. To manage the risk of holding equity securities, the Fund may write call options or purchase put options on securities or securities indexes.

ICON believes that equity markets go through themes over time, simply stated, stocks in industries that were market leaders at one time tend to become overpriced relative to intrinsic value, and stocks in industries that were not in favor tend to drop below intrinsic value. The Fund will sell securities in industries ICON believes are overpriced and buy securities in industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. We believe ICON’s combination of industry rotation and bottom-up valuation distinguishes us from other investment managers. Equity securities in which the Fund may invest include common stocks and preferred stocks of companies of any market capitalization.

The Fund may short securities and may also purchase exchange traded funds, including leveraged and inversed exchange-traded funds (“ETFs”). Leveraged ETFs seek to deliver multiples of the performance of the index or benchmark they track. Inverse ETFs (also called “short” funds) seek to deliver the opposite of the performance of the index or benchmark they track. Like traditional ETFs, some leveraged and inverse ETFs track broad indices, some are sector-specific, and others are linked to commodities, currencies, or some other benchmark.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Like all investments in securities, you risk losing money by investing in the Fund. The main risks of investing in this Fund are:

Industry, Focus and Concentration Risk. Companies that have similar lines of business are grouped together in broad categories called industries. Certain industries are grouped together in broad categories called sectors. The Fund may overweight industries within various sectors and may invest up to 25% of the Fund’s total assets in a single industry. The fact that the Fund may overweight a specific industry or industries may cause the Fund’s performance to be more susceptible to political, economic, business or other developments that affect those industries or sectors. This overweighting means the Fund may be less diverse and more volatile than its benchmark. Moreover, the Fund generally maintains a portfolio of approximately 30 to 40 securities. Holding a smaller, more concentrated portfolio rather than a larger, more diversified portfolio may likewise cause the Fund to be more volatile and susceptible to political, economic, business and other developments, all of which could adversely affect performance.

Small and Mid-Size Company Risk. The Fund may invest in small or mid-size companies which in turn may also involve greater risk of loss and price fluctuation. The trading markets for securities of small-cap issuers may be less liquid and more volatile than securities of larger companies.

Short Sale Risk. If a security sold short increases in price, the Fund may have to cover its short position at a higher price than the short sale price, resulting in a loss. To borrow the security, the Fund also may be required to pay a premium, which would increase the cost of the security sold short. The amount of any gain will be decreased, and the amount of any loss increased, by the amount of the premium, dividends, interest or expenses the Fund may be required to pay in connection with the short sale. In addition, because the Fund’s loss on a short sale arises from increases in the value of the security sold short, such loss is theoretically unlimited. By contrast, the Fund’s loss on a long position arises from decreases in the value of the security and is limited by the fact that a security’s value cannot drop below zero. Because the Fund screens and buys and sells securities using a value based, quantitative methodology, the Fund may be entirely long or entirely short depending on where the Portfolio Manager sees value and reads the market in general.

ETF Risk. Investing in an ETF will provide the Fund with exposure to the securities comprising the index on which the ETF is based and will expose the Fund to risks similar to those of investing directly in those securities. Shares of ETFs typically trade on securities exchanges and may at times trade at a premium or discount to their net asset values. In addition, an ETF may not replicate exactly the performance of the benchmark index it seeks to track for a number of reasons, including transaction costs incurred by the ETF, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of securities held. Investing in ETFs, which are investment companies, involves duplication of advisory fees and certain other expenses. The Fund will pay brokerage commissions in connection with the purchase and sale of shares of ETFs.

Leveraged and Inverse ETF Risk. Risks associated with investing in inverse and leveraged ETFs include compounding risk, derivative securities risk, correlation risk and leverage. Most leveraged and inverse ETFs “reset” daily, meaning that they are designed to achieve their stated objectives on a daily basis. Their performance over longer periods of time - over weeks or months or years - can differ significantly from the performance (or inverse of the performance) of their underlying index or benchmark during the same period of time. This effect can be magnified in volatile markets.

Quantitative Model Risk. Quantitative models and the analysis of specific metrics are used to construct the Fund’s portfolio. The impact of these metrics on a stock’s performance can be difficult to predict, and stocks that previously possessed certain desirable quantitative characteristics may not continue to demonstrate those same characteristics in the future. In addition, relying on quantitative models entails the risk that the models themselves may be limited or incorrect, that the data on which the models rely may be incorrect or incomplete, and that ICON Advisers may not be successful in selecting companies for investment or determining the weighting of particular stocks in the Fund’s portfolio. Any of these factors could cause the Fund to underperform funds with similar strategies that do not select stocks based on quantitative analysis.

Industry, Sector, and Concentration Risk. Companies that have similar lines of business are grouped together in broad categories called industries. Certain industries are grouped together in broader categories called sectors. The Fund may overweight industries within the Consumer Discretionary sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries, including, but not limited to, the Apparel Retail, Apparel, Accessories & Luxury Goods, Auto Parts & Equipment, Automobile Manufacturers, Automotive Retail, Casinos & Gaming, Computer & Electronics Retail, Consumer Electronics, Department Stores, Distributors, Education Services, Footwear, General Merchandise Stores, Home Furnishings, Home Improvement Retail, Homebuilding, Homefurnishing Retail, Hotels, Resorts & Cruise Lines, Household Appliances, Housewares & Specialties, Internet & Direct Marketing Retail, Leisure Facilities, Leisure Products, Motorcycle Manufacturers, Restaurants, Specialized Consumer Services, Specialty Stores, Textiles and Tires & Rubber industries. The Fund is subject to the risk that securities within the sector will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Consumer Discretionary sector. The performance of companies operating in the Consumer Discretionary sector will also be affected by economic growth, consumer confidence, attitudes and spending. Changes in demographics and consumer tastes also can affect the demand for, and success of, consumer products and services in the marketplace. Moreover, the Consumer Discretionary sector encompasses businesses that tend to be sensitive to economic cycles.

The Fund may overweight industries within the Consumer Staples sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries, including the Agricultural Products, Brewers, Distillers & Vintners, Drug Retail, Food Distributors, Food Retail, Household Products, Hypermarkets & Super Centers, Packaged Foods & Meats, Personal Products, Soft Drinks and Tobacco industries. The Fund is subject to the risk that securities within the sector will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Consumer Staples sector. The performance of companies operating in the Consumer Staples sector will also be affected by consumer confidence, demands and preferences, and spending. In addition, companies in the Consumer Staples sector may be subject to risks pertaining to the supply of, demand for, and prices of raw materials.

The Fund may overweight industries within the Financial sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries, including the Asset Management & Custody Banks, Consumer Finance, Diversified Banks, Diversified Capital Markets, Financial Exchanges & Data, Insurance Brokers, Investment Banking & Brokerage, Life & Health Insurance, Mortgage REITS, Multi-line Insurance, Multi-sector Holdings, Other Diversified Financial Services, Property & Casualty Insurance, Regional Banks, Reinsurance, Specialized Finance, and Thrifts & Mortgage Finance industries. The Financials sector includes companies involved in banking, thrifts and mortgage finance, specialized finance, consumer finance, asset management and custody banks, investment banking and brokerage and insurance. The Fund is subject to the risk that securities within the sector will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Financials sector. Companies operating in the Financials sector are subject to extensive government regulation, which may limit the financial commitments they can make and the interest rates and fees they can charge. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition.

Stock Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, national or international political events, natural disasters, the spread of infectious illness or other public health issue, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally.

Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means it may own larger positions in a smaller number of securities than portfolios that are “diversified”. The Fund may invest up to 25% of its total assets in the securities of one issuer. This means that an increase or decrease in the value of a single security likely will have a greater impact on the Fund’s net asset value (“NAV”) and total return than a diversified portfolio. The Fund’s share prices may also be more volatile than those of a diversified fund.

Small and Mid-Size Company Risk. The Fund may invest in small or mid-size companies which in turn may offer greater risk of loss and price fluctuation. The trading markets for securities of small-cap issuers may be less liquid and more volatile than securities of larger companies.

Manager Risk. ICON Advisers’ opinion about the intrinsic worth or creditworthiness of a company or security may be incorrect, or the market may continue to undervalue the company or security. ICON Advisers may not make timely purchases or sales of securities for the Fund.

Principal Investment Strategies. The Fund uses a quantitative methodology to identify securities ICON Advisers, Inc. (“ICON”) the Fund’s investment sub-advisor believes are underpriced relative to value. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies the Fund considers Natural Resources and/or Infrastructure focused, which are companies in the Energy, Industrials, Materials and Utilities sectors (as determined by the Global Industry Classification Standard) and otherwise described below. There is no minimum or maximum with respect to the amount the Fund may invest in any particular sector.

The Energy sector includes, but is not limited to: Coal & Consumable Fuels, Integrated Oil & Gas, Oil & Gas Drilling, Oil & Gas Equipment & Services, Oil & Gas Exploration & Production, Oil & Gas Refining & Marketing, and Oil & Gas Storage & Transportation.

The Industrials sector includes, but is not limited to: Aerospace & Defense, Agricultural & Farm Machinery, Air Freight & Logistics, Airlines, Airport Services, Building Products, Commercial Printing, Construction & Engineering, Construction Machinery & Heavy Trucks, Diversified Support Services, Electrical Components & Equipment, Environmental & Facilities Services, Heavy Electrical Equipment, Highways & Railtracks, Human Resources & Employment Services, Industrial Conglomerates, Industrial Machinery, Marine, Marine Ports & Services, Office Services & Supplies, Railroads, Research & Consulting Services, Security & Alarm Services, Trading Companies & Distributors, and Trucking.

The Materials sector includes, but is not limited to: Specialty Chemicals, Paper Products, Paper Packaging, Metal & Glass Containers, Silver, Diversified Metals & Mining, Construction Materials, Industrial Gases, Steel, Gold, Fertilizers & Agricultural Chemicals, Forest Products, Commodity Chemicals, Precious Metals & Minerals, Diversified Chemicals, Copper, and Aluminum.

The Utilities sector includes, but is not limited to: Electric Utilities, Gas Utilities, Multi-Utilities, Water Utilities, Independent Power Producers & Energy Traders, and Renewable Electricity.

The Fund invests in foreign companies and U.S. companies that have principal operations in foreign jurisdictions. While ICON typically seeks to anchor the Fund’s assets in the United States, the Fund may also invest in foreign securities. Exposure to companies in any one particular foreign country typically is less than 20% of the Fund’s total assets. The Fund also may have exposure to companies located in, and/or doing business in, emerging markets.

Generally, in determining whether to buy or sell a security, ICON identifies industries, sectors and countries that our methodology suggests are underpriced relative to our calculation of intrinsic value. In determining whether to buy or sell a security, the Fund may consider various other factors, including whether the security has sufficiently exceeded ICON’s calculation of the security’s intrinsic value price, whether a value-oriented company has failed to actualize that value, the effect of commodity price trends on certain holdings, the relative strength of the security in the industry, sector or market in general, or whether a company has experienced a change in its valuation. The Fund may also sell a security to take advantage of what it believes are more attractive investment opportunities, to reduce the Fund’s holding in that security, or to raise cash.

The Fund may also purchase exchange traded funds (“ETFs”). ETFs track broad indices, some are sector-specific, and others are linked to commodities, currencies, or some other benchmark.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Like all investments in securities, you risk losing money by investing in the Fund. The main risks of investing in this Fund are:

The Fund may overweight industries within the Energy sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries, including the Energy Equipment & Services and Oil, Gas & Consumable Fuels industries. Issuers in energy-related industries can be significantly affected by fluctuations in energy prices and supply and demand of energy fuels. Markets for various energy-related commodities can have significant volatility, and are subject to control or manipulation by large producers or purchasers. Companies in the Energy sector may need to make substantial expenditures, and to incur significant amounts of debt, in order to maintain or expand their reserves. Oil and gas exploration and production can be significantly affected by natural disasters as well as changes in exchange rates, interest rates, government regulation, world events (including, but not limited to, instability in the Middle East), energy conservation, alternative energy sources, increases in energy efficiencies and economic conditions. These companies may be at risk for environmental damage claims.

The Fund may overweight industries within the Industrials sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries, including but not limited to the Aerospace & Defense, Agricultural & Farm Machinery, Air Freight & Logistics, Airlines, Airport Services, Building Products, Commercial Printing, Construction & Engineering, Construction Machinery & Heavy Trucks, Diversified Support Services, Electrical Components & Equipment, Environmental & Facilities Services, Heavy Electrical Equipment, Highways & Railtracks, Human Resources & Employment Services, Industrial Conglomerates, Industrial Machinery, Marine, Marine Ports & Services, Office Services & Supplies, Railroads, Research & Consulting Services, Security & Alarm Services, Trading Companies & Distributors, and Trucking industries. The Fund is subject to the risk that securities within the sector will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Industrials sector. The prices of the securities of companies operating in the Industrials sector may fluctuate due to the level and volatility of commodity prices, the exchange value of the dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

The Fund may overweight industries within the Natural Resources sectors, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries, which include but are not limited to the energy (such as electricity and gas utilities, producers and developers, equipment and services, storage and transportation, gas/oil refining and marketing, service and drilling, pipelines and master limited partnerships (MLPs)), alternative energy (such as uranium, coal, nuclear, hydrogen, wind, solar, fuel cells), industrial products (such as building materials, cement, packaging, chemicals, materials infrastructure, supporting transport and machinery), forest products (such as lumber, plywood, pulp, paper, newsprint, tissue), base metals (such as aluminum, copper, nickel, zinc, iron ore and steel), precious metals and minerals (such as gold, silver, platinum, diamonds), and agricultural products (grains and other foods, seeds, fertilizers, water) industries. Investments in the natural resources and related sectors may be affected by numerous factors. For example, natural disaster (e.g. earthquakes or fires) and political events (such as coups or military campaigns) can affect the overall supply of a natural resource and the value of companies involved in such natural resource. Political risks and other risks to which foreign securities are subject also may affect domestic companies in which the Fund invests if they have significant operations or investments in foreign countries. In addition, interest rates, prices of raw materials and other commodities, international economic developments, energy conservation, tax and other government regulations (both domestic and foreign) may affect the supply of and demand for natural resources, which can affect the profitability and value of securities issued by companies in the natural resources sectors. Securities of companies within specific natural resources sectors can perform differently than the overall market. This may be due to changes in such things as the regulatory or competitive environment or to changes in investor perceptions regarding a sector. Because the Fund may allocate relatively more assets to certain natural resources sectors than others, the Fund’s performance may be more sensitive to developments which affect those sectors emphasized by the Fund.

Developing and Emerging Markets Risk. The economies of developing or emerging market countries may be more dependent on relatively few industries that may be highly vulnerable to local and global changes than economies in more developed countries. The governments of developing and emerging market countries may be less stable than the governments of more developed countries. Countries in the emerging markets generally have less developed securities markets or exchanges, and less developed legal and accounting systems, reduced availability of public information, and lack of uniform financial reporting and regulatory practices, which in turn may adversely impact the Fund’s ability to calculate accurately the intrinsic value of the securities. Securities of emerging or developing market companies may be less liquid and more volatile than securities in countries with more mature markets. The value of developing or emerging market currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company’s assets, restrictions on foreign ownership of local companies and restrictions on withdrawing assets from the country. Investments in securities of issuers in developing or emerging market countries may be considered speculative and higher risk.

Global Natural Resources Risk. Global natural resources risks include price fluctuation caused by inflationary trends (whether actual or imagined), political developments, changes in energy or materials costs, changes in the supply of or demand for different natural resources, the costs assumed by natural resources companies in complying with environmental and safety regulations, and the risks associated with natural and man-made disasters.

Globalization Risk. The growing inter-relationship of global economies and financial markets has increased the effect of conditions in one country or region on issuers of securities in a different country or region. In particular, the adoption or prolongation of protectionist trade policies by one or more countries, changes in economic or monetary policy in the United States or abroad, or a slowdown in the U.S. economy, could lead to a decrease in demand for products and reduced flows of capital and income to companies in other countries. Those events might particularly affect companies in emerging and developing market countries.

Regional Focus. At times, the Fund might increase the relative emphasis of its investments in a particular region of the world. Stocks of issuers in a region might be affected by changes economic conditions or by changes in government regulations, availability of basic resources or supplies, or other events that affect that region more than others. If the Fund has a greater emphasis on investments in a particular region, it may be subject to greater risks from adverse events that occur in that region than the Fund that invests in a different region or that is more geographically diversified. Political, social or economic disruptions in the region may adversely affect the values of the Fund’s holdings.

Foreign Investment Risk. Investments in foreign securities involve different risks than U.S. investments, including fluctuations in currency exchange rates, potentially unstable political and economic structures, less efficient trade settlement practices, reduced availability of public information, and lack of uniform financial reporting and regulatory practices similar to those that apply to U.S. issuers. Foreign stock markets may also be less liquid and more volatile than U.S. stock markets.

Like all investments in securities, you risk losing money by investing in the Fund. The main risks of investing in this Fund are:

The Fund may overweight industries within the Information Technology sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries, including the Application Software, Communications Equipment, Data Processing & Outsourced Services, Electronic Components, Electronic Equipment & Instruments, Electronic Manufacturing Services, Internet Services & Infrastructure, IT Consulting & Other Services, Semiconductor Equipment, Semiconductors, Systems Software, Technology Distributors and Technology Hardware, Storage & Peripherals industries. The Fund is subject to the risk that securities within the sector will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Information Technology sector. The prices of the securities of companies operating in the Information Technology Sector are closely tied to market competition, and may also demonstrate increased sensitivity to short product cycles and aggressive pricing, and problems with bringing products to market.

The Fund may overweight industries within the Health Care sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries, including the Biotechnology, Health Care Distributors, Health Care Equipment, Health Care Facilities, Health Care Services, Health Care Supplies, Health Care Technology, Life Sciences Tools & Services, Managed Health Care, and Pharmaceuticals industries. The Fund is subject to the risk that securities within the sector will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Health Care sector. The prices of the securities of companies operating in the Health Care sector are closely tied to government regulation and approval of their products and services, which can have a significant effect on the price and availability of those products and services. Competition, patent considerations, regulatory approval of products, and government proposed and adopted regulation may impact the performance of the Fund. Many of these products and services are also subject to rapid obsolescence, which may lower the market value of the securities of the companies in this sector.

(“ICON”) the Fund’s investment sub-advisor believes are underpriced relative to value.

This strategy may not be changed unless the Fund shareholders are given at least 60 days prior notice. Equity securities in which the Fund may invest include common stocks and preferred stocks of companies of any market capitalization.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Like all investments in securities, you risk losing money by investing in the Fund. The main risks of investing in this Fund are:

Industry, Sector, and Concentration Risk. Companies that have similar lines of business are grouped together in broad categories called industries. Certain industries are grouped together in broader categories called sectors. The Fund overweights industries within the Utilities sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries, including the Electric Utilities, Gas Utilities, Independent Power Producers & Energy Traders, Multi-utilities, Renewable Electricity and Water Utilities industries. Utility companies are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, and rate caps or rate changes. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. The recent trend towards deregulation in the Utilities sector presents special risks. Utility companies may be subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company’s equipment unusable or obsolete and negatively impact profitability. Additional risks can include fuel and other operating cost increases, restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations, and difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices.

[3]	The MSCI ACWI Ex USA Index is a free float-adjusted market capitalization index that is designed to measure developed and developing market equity performance, excluding the U.S. MSCI, Inc. publishes two versions of this Index reflecting the reinvestment of dividends using two different methodologies: gross dividends and net dividends. While both versions reflect reinvested dividends, they differ with respect to the manner in which taxes associated with dividend payments are treated. In calculating the gross dividends version, MSCI reinvests as much as possible of a company’s dividend distributions. The reinvested amount is equal to the total dividend amount distributed to persons residing in the country of the dividend-paying company. Gross total return indexes do not, however, include any tax credits. In calculating the net dividends version, MSCI incorporates reinvested dividends applying the withholding tax rate applicable to foreign non-resident institutional investors that do not benefit from double taxation treaties.
