Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	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 50.92% of the average value of its whole portfolio.

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. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies in the Utilities sectors (as determined by the Global Industry Classification Standard) including, but not limited to: Electric Utilities, Gas Utilities, Independent Power Producers & Energy Traders, Multi-utilities and Water Utilities. 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.
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 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. For example, general economic conditions, supply and demand, competition, and government regulation or deregulation may impact the performance of this Fund. The recent trend towards deregulation in the Utilities industries presents special risks. Companies may be faced with increased competition and may become less profitable. Non-Diversified Portfolio Risk. The Fund is "non-diversified" which means that 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 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.
Risk Lose Money [Text]	rr_RiskLoseMoney	Like all investments in securities, you risk losing money by investing in the Fund.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies.
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund uses a quantitative methodology to identify industries and sectors in small company securities that ICON’s methodology suggests are underpriced or overpriced relative to our calculation of intrinsic value. ICON believes that the 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. We sell industries we believe are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. ICON’s combination of industry rotation and bottom-up valuation of small company equities distinguishes us from other small company investment managers. Normally, the Fund will invest at least 80% of its net assets (including any borrowings for investment purposes) in companies with a market capitalization that is within or below the range of companies in the S&P SmallCap 600 Index. The market capitalization of the companies in the Fund’s portfolio and the S&P SmallCap 600 Index changes over time, and the Fund will not sell a stock just because the company has grown to a market capitalization outside the range. This strategy may not be changed unless Fund shareholders are given at least 60 days’ prior notice. The Fund invests primarily in equity securities, including common stocks, preferred stocks, and equity interests in trusts (including real estate investment trusts), partnerships, joint ventures, and limited liability companies. The Fund considers equity securities to include rights offerings and investments that convert into the equity securities.
Risk [Heading]	rr_RiskHeading	Principal Investment Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investing in the Fund involves risk, including the risk that you may receive little or no return on your investment. When you redeem your shares, they may be worth more or less than what you paid for them, which means that you may lose a portion or all of the money you invested in the Fund. The Fund invests principally in stocks and other securities that may experience significant volatility at times and may fall sharply in response to adverse events. Individual securities also may experience dramatic movements in price. In addition to the risks of overall market movements, risks of events affecting a particular industry or sector, and risks that are specific to an individual security, the principal risks of investing in the Fund, which could adversely affect its performance, include: Small Company Risk. Securities of small companies generally involve greater risks than investments in larger companies. Small companies may have limited management experience or depth, limited access to capital, or limited products or services, or operate in markets that have not yet been established. Small company securities tend to be more volatile and less liquid than equity securities of larger companies. Value Investing Risk. The prices of value stocks may lag the stock market for long periods of time if the market fails to recognize ICON’s evaluation of the company’s intrinsic worth. Active Management Risk. The Fund is subject to the risk that the investment adviser’s judgments about the attractiveness, value, or potential appreciation of the Fund’s investments may prove to be incorrect. If the securities selected and strategies employed by the Fund fail to produce the intended results, the Fund could underperform other funds with similar objectives and investment strategies. 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 broader 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 the 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence.

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. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies in the Consumer Discretionary sector (as determined by the Global Industry Classification Standard) including, but not limited to: Advertising, Apparel & Accessories & Luxury Goods, Apparel Retail, Auto Parts & Equipment, Automobile Manufacturers, Automotive Retail, Broadcasting, Cable & Satellite, Casinos & Gaming, Catalog Retail, Computer & Electronics Retail, Consumer Electronics, Department Stores, Distributors, Education Services, Footwear, General Merchandise Stores, Home Furnishing Retail, Home Furnishings, Home Improvement Retail, Homebuilding, Hotels, Resorts & Cruise Lines, Household Appliances, Housewares & Specialties, Internet Retail, Leisure Facilities, Leisure Products, Motorcycle Manufacturers, Movies & Entertainment, Photographic Products, Publishing, Restaurants, Specialized Consumer Services, Specialty Stores, Textiles and Tires & Rubber. 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.
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 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 Consumer Discretionary sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries. For example, consumer confidence and spending, changes in demographics and consumer tastes, interest rates, and competition may impact the performance of the Fund. Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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. It normally invests in equity securities of companies of any market capitalization and traded in U.S. markets. The Fund will generally take long positions in equity securities identified as undervalued and take short positions in equity securities identified as overvalued. This strategy may not be changed unless Fund shareholders are given at least 60 days' prior notice. Each long or short position will be determined by considering the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio. 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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. ICON's combination of industry rotation and bottom-up valuation distinguishes us from other investment managers.
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: 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. Segregated Account Risk. Until the Fund replaces a borrowed security, it is required to maintain a segregated account of cash or highly liquid securities with a broker or custodian to cover the Fund's short position. Securities held in a segregated account cannot be sold while the position they are covering is outstanding, unless they are replaced with similar securities. As a result, there is the possibility that segregation of a large percentage of the Fund's assets could affect its portfolio management. 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. Foreign Investment Risk. Up to 20% of the Fund's net assets may be invested in foreign securities. 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 than U.S. stock markets. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example ICON Consumer Staples Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	839	1,155	1,590	2,795
Class C	354	948	1,666	3,567
Class S	154	486	842	1,843

You would pay the following expenses if you did not redeem your Class C shares:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
ICON Consumer Staples Fund Class C	254	948	1,666	3,567

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 81.81% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON 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 in the Consumer Staples sector (as determined by the Global Industry Classification Standard) including, but not limited to: 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. 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

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 broader categories called sectors. The Fund overweights 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. For example, the Fund’s performance may be impacted by general economic conditions, consumer confidence, consumer preferences, product cycles, competition, and changes in government regulation.

Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.
Risk Lose Money [Text]	rr_RiskLoseMoney	Like all investments in securities, you risk losing money by investing in the Fund.
Risk Nondiversified Status [Text]	rr_RiskNondiversifiedStatus	Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example ICON Materials Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	838	1,168	1,617	2,858
Class C	354	1,139	2,038	4,340
Class S	142	441	761	1,669

You would pay the following expenses if you did not redeem your Class C shares:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
ICON Materials Fund Class C	254	1,139	2,038	4,340

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 40.89% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON 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 in the Materials sector (as determined by the Global Industry Classification Standard) including, but not limited to Aluminum, Commodity Chemicals, Construction Materials, Diversified Chemicals, Diversified Metals & Mining, Fertilizers & Agricultural Chemicals, Forest Products, Gold, Industrial Gases, Metal & Glass Containers, Paper Packaging, Paper Products, Precious Metals & Minerals, Specialty Chemicals, and Steel. 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

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 broader categories called sectors. The Fund overweights industries within the Materials sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries. For example, general economic conditions, commodity prices, competition, and changes in government regulation may impact the performance of the Fund.

Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in foreign equity securities in the European region. Foreign equity securities in the European region include securities of issuers wherever organized, whose securities are traded principally on a recognized stock exchange or over-the-counter market in the countries listed in the Morgan Stanley Capital International (“MSCI”) Europe Index. The European Region includes the following countries: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, Poland, Portugal, Spain, the Netherlands, Norway, Sweden, Switzerland, Turkey and the United Kingdom. This strategy may not be changed unless Fund shareholders are given at least 60 days’ prior notice. 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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. 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 and preferred stocks of companies of any market capitalization.
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: Non-Diversified Portfolio Risk. The ICON Europe Fund is “non-diversified” which means that a Fund may own larger positions in a smaller number of securities than funds 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 fund. The Fund’s share prices may also be more volatile than those of a diversified fund. 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. 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. Geographic Risk. The Fund will be more susceptible to the economic, market, political and local risks of the European region than a fund that is more geographically diversified. Europe includes both developed and emerging markets. Most Western European countries are members of the European Union, which imposes restrictions on inflation rates, deficits and debt levels. Unemployment in Europe has historically been high. Many Eastern European countries continue to move toward market economies, however, their markets remain relatively underdeveloped. 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

[1] A contingent deferred sales charge of 1.00% applies on certain redemptions within one year following purchases of $1 million or more made without an initial sales charge.

[2] ICON has contractually agreed to limit the total expenses of the Fund (excluding interest, taxes, brokerage and extraordinary expenses) to an annual rate for Class A of 1.80% and Class C of 2.55%. This expense limitation may be terminated at any time after January 31, 2021 upon 30 days written notice of termination to the Fund's Board of Trustees. ICON is entitled to reimbursement from the Fund of any fees waived pursuant to this arrangement if such reimbursement does not cause the Fund to exceed existing expenses limitations and the reimbursement is made within three years after the expenses were reimbursed or absorbed.

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. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies in the Materials sector (as determined by the Global Industry Classification Standard) including, but not limited to Aluminum, Commodity Chemicals, Construction Materials, Diversified Chemicals, Diversified Metals & Mining, Fertilizers & Agricultural Chemicals, Forest Products, Gold, Industrial Gases, Metal & Glass Containers, Paper Packaging, Paper Products, Precious Metals & Minerals, Specialty Chemicals, and Steel. 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.
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 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 Materials sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries. For example, general economic conditions, commodity prices, competition, and changes in government regulation may impact the performance of the Fund. Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies in the Consumer Staples sector (as determined by the Global Industry Classification Standard) including, but not limited to: 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. 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.
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 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 Consumer Staples sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries. For example, the Fund’s performance may be impacted by general economic conditions, consumer confidence, consumer preferences, product cycles, competition, and changes in government regulation. Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

ICON Energy Fund Class C	239	736	1,260	2,696

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 74.41% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON 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 in the Energy sector (as determined by the Global Industry Classification Standard) including, but not limited to: Coal & Consumable Fuels, Integrated Oil & Gas, Oil & Gas Drilling, Oil & Gas Equipment & Services, Oil & Gas Exploration & Production, and Oil & Gas Refining, Marketing, Oil & Gas Storage & Transportation. 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

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 broader categories called sectors. The Fund overweights 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. For example, energy prices, supply and demand fluctuations, energy conservation, tax and other regulatory policies of governments, and global events including instability in the Middle East or war may impact the performance of the Fund.

Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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 91.24% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON 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 in the Consumer Discretionary sector (as determined by the Global Industry Classification Standard) including, but not limited to: Advertising, Apparel & Accessories & Luxury Goods, Apparel Retail, Auto Parts & Equipment, Automobile Manufacturers, Automotive Retail, Broadcasting, Cable & Satellite, Casinos & Gaming, Catalog Retail, Computer & Electronics Retail, Consumer Electronics, Department Stores, Distributors, Education Services, Footwear, General Merchandise Stores, Home Furnishing Retail, Home Furnishings, Home Improvement Retail, Homebuilding, Hotels, Resorts & Cruise Lines, Household Appliances, Housewares & Specialties, Internet Retail, Leisure Facilities, Leisure Products, Motorcycle Manufacturers, Movies & Entertainment, Photographic Products, Publishing, Restaurants, Specialized Consumer Services, Specialty Stores, Textiles and Tires & Rubber.

Equity securities in which the Fund may invest include common stocks and preferred stocks of companies of any market capitalization.

Principal Investment Risks

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 broader categories called sectors. The Fund overweights 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. For example, consumer confidence and spending, changes in demographics and consumer tastes, interest rates, and competition may impact the performance of the Fund.

Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund uses a quantitative methodology to identify securities ICON 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. 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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. 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.
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 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth. 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. Foreign Investment Risk. Up to 20% of the Fund’s net assets may be invested in foreign securities. 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 than U.S. stock markets.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example ICON Europe Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	841	1,109	1,493	5,082
Class C	358	793	1,355	6,595
Class S	159	493	851	1,857

You would pay the following expenses if you did not redeem your Class C shares:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
ICON Europe Fund Class C	258	793	1,355	6,595

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 89.78% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON believes are underpriced relative to value. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in foreign equity securities in the European region. Foreign equity securities in the European region include securities of issuers wherever organized, whose securities are traded principally on a recognized stock exchange or over-the-counter market in the countries listed in the Morgan Stanley Capital International (“MSCI”) Europe Index. The European Region includes the following countries: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, Poland, Portugal, Spain, the Netherlands, Norway, Sweden, Switzerland, Turkey and the United Kingdom. This strategy may not be changed unless Fund shareholders are given at least 60 days’ prior notice.

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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. 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 and preferred stocks of companies of any market capitalization.

Principal Investment Risks

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

Non-Diversified Portfolio Risk. The ICON Europe Fund is “non-diversified” which means that a Fund may own larger positions in a smaller number of securities than funds 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 fund. The Fund’s share prices may also be more volatile than those of a diversified fund.

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.

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.

Geographic Risk. The Fund will be more susceptible to the economic, market, political and local risks of the European region than a fund that is more geographically diversified. Europe includes both developed and emerging markets. Most Western European countries are members of the European Union, which imposes restrictions on inflation rates, deficits and debt levels. Unemployment in Europe has historically been high. Many Eastern European countries continue to move toward market economies, however, their markets remain relatively underdeveloped.

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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON believes are underpriced relative to value. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in foreign equity securities in the Asia-Pacific Region. Foreign equity securities in the Asia-Pacific Region include securities of issuers, wherever organized, whose securities are traded principally on a recognized stock exchange or over-the-counter market in the countries listed in the Morgan Stanley Capital International (“MSCI”) All Country (“AC”) Asia-Pacific Index. The Asia-Pacific Region includes the following countries: Australia, China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, New Zealand, Philippines, Singapore, Taiwan and Thailand. This strategy may not be changed unless Fund shareholders are given at least 60 days’ prior notice.

Foreign stock markets may also be less liquid and more volatile than U.S. stock markets.

Geographic Risk. The Fund will be more susceptible to the economic, market, regulatory, political, natural disasters and local risks of the Asia-Pacific region than a fund that is more geographically diversified. The Asia-Pacific region includes countries in all stages of economic development; however, it has a higher prevalence of “emerging market” countries as compared to other regions of the world. Such emerging countries can be characterized as having less-developed legal and financial structures, over-extensions of credit, currency devaluations and restrictions, high inflation and unemployment. The region has historically been highly dependent on global trade, with nations taking strong roles in both the importing and exporting of goods; such a relationship creates a risk with this dependency on global growth. The respective stock markets tend to have a larger prevalence of smaller companies which are inherently more volatile and less liquid than larger comparables. Varying levels of accounting and disclosure standards, restrictions on foreign ownership, minority ownership rights, and corporate governance standards are also common for the region.

Non-Diversified Portfolio Risk. The ICON Asia-Pacific Region Fund is “non-diversified” which means that a Fund may own larger positions in a smaller number of securities than funds 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 fund.

It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies in the Industrials sector (as determined by the Global Industry Classification Standard) including, but not limited to: Aerospace & Defense, Air Freight & Logistics, Airlines, Airport Services, Building Products, Commercial Printing, Construction & Engineering, Construction & Farm Machinery & Heavy Equipment, 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. 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

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 broader categories called sectors. The Fund overweights 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. For example, general economic conditions, interest rates, insurance costs, technical progress, capital-spending levels, labor relations and government regulation may impact the performance of the Fund.

Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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. 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 bonds. These include corporate bonds, notes and debentures, 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 25% of its assets in lower-rated securities. There is no limit on the Fund’s average maturity or on the maturity of any individual issues in the Fund. 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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. ICON’s combination of industry rotation and bottom-up valuation distinguishes us from other investment managers.
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: 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. Credit Risk. The Fund could lose money if the issuer of a 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 bond can cause a bond’s price to fall, potentially affecting the Fund’s share price. 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. High Yield Risk. The Fund may invest 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. Call Risk. Some debt securities allow the issuer to repay the obligation early; these are referred to as “callable securities.” Issuers will often repay the obligation underlying a callable security when interest rates are low. To the extent that the Fund holds callable securities and the issuer repays the securities early, the Fund may not benefit fully from the increase in value that other debt securities experience when rates decline. In addition, the Fund likely would have to reinvest the proceeds of the payoff at current yields, which will likely be lower than those paid by the callable security that was paid off. Government Agency Securities Risk. Securities issued by U.S. government agencies or government-sponsored enterprises may not be guaranteed by the U.S. Treasury. Government National Mortgage Association (“Ginnie Mae”) is authorized to guarantee, with the full faith and credit of the U.S. government, the timely payment of principal and interest on securities issued by institutions approved by Ginnie Mae and backed by pools of mortgages insured by the Federal Housing Administration or guaranteed by the Department of Veteran Affairs. Government-related guarantors are not backed by the full faith and credit of the U.S. government and include the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Pass-through securities issued by Fannie Mae are guaranteed as to timely payment of principal and interest by Fannie Mae, but are not backed by the full faith and credit of the U.S. government. Freddie Mac guarantees the timely payment of interest and ultimate collection of principal, but its participation certificates are not backed by the full faith and credit of the U.S. government. 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. Market Risk. The Fund’s overall risk level will depend on the market sectors in which the Fund is invested and the current interest rate, liquidity conditions, and credit quality of such sectors. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example ICON Bond Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	667	841	1,130	1,952
Class C	248	505	871	2,080
Class S	77	240	417	967

You would pay the following expenses if you did not redeem your Class C shares:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
ICON Bond Fund Class C	163	505	871	2,080

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 51.28% of the average value of the portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON 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 bonds. These include corporate bonds, notes and debentures, 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 25% of its assets in lower-rated securities. There is no limit on the Fund’s average maturity or on the maturity of any individual issues in the Fund.

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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. ICON’s combination of industry rotation and bottom-up valuation distinguishes us from other investment managers.

Principal Investment Risks

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

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.

Credit Risk. The Fund could lose money if the issuer of a 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 bond can cause a bond’s price to fall, potentially affecting the Fund’s share price.

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.

High Yield Risk. The Fund may invest 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.

Call Risk. Some debt securities allow the issuer to repay the obligation early; these are referred to as “callable securities.” Issuers will often repay the obligation underlying a callable security when interest rates are low. To the extent that the Fund holds callable securities and the issuer repays the securities early, the Fund may not benefit fully from the increase in value that other debt securities experience when rates decline. In addition, the Fund likely would have to reinvest the proceeds of the payoff at current yields, which will likely be lower than those paid by the callable security that was paid off.

Government Agency Securities Risk. Securities issued by U.S. government agencies or government-sponsored enterprises may not be guaranteed by the U.S. Treasury. Government National Mortgage Association (“Ginnie Mae”) is authorized to guarantee, with the full faith and credit of the U.S. government, the timely payment of principal and interest on securities issued by institutions approved by Ginnie Mae and backed by pools of mortgages insured by the Federal Housing Administration or guaranteed by the Department of Veteran Affairs. Government-related guarantors are not backed by the full faith and credit of the U.S. government and include the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Pass-through securities issued by Fannie Mae are guaranteed as to timely payment of principal and interest by Fannie Mae, but are not backed by the full faith and credit of the U.S. government. Freddie Mac guarantees the timely payment of interest and ultimate collection of principal, but its participation certificates are not backed by the full faith and credit of the U.S. government.

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.

Market Risk. The Fund’s overall risk level will depend on the market sectors in which the Fund is invested and the current interest rate, liquidity conditions, and credit quality of such sectors. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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 50.92% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON 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 in the Utilities sectors (as determined by the Global Industry Classification Standard) including, but not limited to: Electric Utilities, Gas Utilities, Independent Power Producers & Energy Traders, Multi-utilities and Water Utilities. 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

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 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. For example, general economic conditions, supply and demand, competition, and government regulation or deregulation may impact the performance of this Fund. The recent trend towards deregulation in the Utilities industries presents special risks. Companies may be faced with increased competition and may become less profitable.

Non-Diversified Portfolio Risk. The Fund is "non-diversified" which means that 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 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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in foreign equity securities. Foreign equity securities refer to securities of issuers, wherever organized, whose securities are listed or traded principally on a recognized stock exchange or over-the-counter market outside the United States. This strategy may not be changed unless Fund shareholders are given at least 60 days’ prior notice. 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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. 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 and preferred stocks of companies of any market capitalization.
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: 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. 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 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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. It 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. 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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. ICON’s combination of industry rotation and bottom-up valuation distinguishes us from other investment managers. The Fund generally invests 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 lower-rated securities.
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: Credit Risk. The Fund could lose money if the issuer of a 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 convertible security can cause a convertible security’s price to fall, potentially lowering the Fund’s share price. 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. 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. 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth. 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. Government Agency Securities Risk. Securities issued by U.S. government agencies or government-sponsored enterprises may not be guaranteed by the U.S. Treasury. Government National Mortgage Association (“Ginnie Mae”) is authorized to guarantee, with the full faith and credit of the U.S. government, the timely payment of principal and interest on securities issued by institutions approved by Ginnie Mae and backed by pools of mortgages insured by the Federal Housing Administration or guaranteed by the Department of Veteran Affairs. Government-related guarantors are not backed by the full faith and credit of the U.S. government and include the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Pass-through securities issued by Fannie Mae are guaranteed as to timely payment of principal and interest by Fannie Mae, but are not backed by the full faith and credit of the U.S. government. Freddie Mac guarantees the timely payment of interest and ultimate collection of principal, but its participation certificates are not backed by the full faith and credit of the U.S. government. Foreign Investment Risk. Up to 20% of the Fund’s net assets may be invested in foreign securities. 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 than U.S. stock markets.

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 47.59% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund using a quantitative methodology to identify securities ICON 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 in the Health Care sector (as determined by the Global Industry Classification Standard) including, but not limited to: 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. 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

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 broader categories called sectors. The Fund overweights 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. For example, competition, patent considerations, regulatory approval of products, and government 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.

Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example ICON Information Technology Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	837	1,313	1,908	3,510
Class C	353	1,172	2,101	4,468
Class S	136	424	734	1,612

You would pay the following expenses if you did not redeem your Class C shares:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
ICON Information Technology Fund Class C	253	1,172	2,101	4,468

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 35.22% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON 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 in the Information Technology sector (as determined by the Global Industry Classification Standard) including, but not limited to: Application Software, Communications Equipment, Computer Hardware, Computer Storage & Peripherals, Data Processing & Outsourced Services, Electronic Components, Electronic Equipment & Instruments, Electronic Manufacturing Services, Home Entertainment Software, Internet Software & Services, IT Consulting & Other Services, Office Electronics, Semiconductor Equipment, Semiconductors, Systems Software and Technology Distributors. 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

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 broader categories called sectors. The Fund overweights 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. For example, the Fund’s performance may be impacted by general economic conditions, product cycles, competition, and government regulation. In addition, technological services and products are subject to rapid obsolescence which may lower the market value of the securities in the sector.

Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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 23.73% of the average value of the portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON 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.

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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. 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.

Principal Investment Risks

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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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.

Foreign Investment Risk. Up to 20% of the Fund’s net assets may be invested in foreign securities. 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 than U.S. stock markets.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	1 Year	3 Years
ICON Opportunities Fund	153	1,579

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. No portfolio turnover rate is provided because the Fund has not completed at least six months of operations as of the date of this prospectus.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify industries and sectors in small company securities that ICON’s methodology suggests are underpriced or overpriced relative to our calculation of intrinsic value. ICON believes that the 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. We sell industries we believe are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. ICON’s combination of industry rotation and bottom-up valuation of small company equities distinguishes us from other small company investment managers. Normally, the Fund will invest at least 80% of its net assets (including any borrowings for investment purposes) in companies with a market capitalization that is within or below the range of companies in the S&P SmallCap 600 Index. The market capitalization of the companies in the Fund’s portfolio and the S&P SmallCap 600 Index changes over time, and the Fund will not sell a stock just because the company has grown to a market capitalization outside the range. This strategy may not be changed unless Fund shareholders are given at least 60 days’ prior notice.

The Fund invests primarily in equity securities, including common stocks, preferred stocks, and equity interests in trusts (including real estate investment trusts), partnerships, joint ventures, and limited liability companies. The Fund considers equity securities to include rights offerings and investments that convert into the equity securities.

Principal Investment Risks

Investing in the Fund involves risk, including the risk that you may receive little or no return on your investment. When you redeem your shares, they may be worth more or less than what you paid for them, which means that you may lose a portion or all of the money you invested in the Fund. The Fund invests principally in stocks and other securities that may experience significant volatility at times and may fall sharply in response to adverse events. Individual securities also may experience dramatic movements in price. In addition to the risks of overall market movements, risks of events affecting a particular industry or sector, and risks that are specific to an individual security, the principal risks of investing in the Fund, which could adversely affect its performance, include:

Small Company Risk. Securities of small companies generally involve greater risks than investments in larger companies. Small companies may have limited management experience or depth, limited access to capital, or limited products or services, or operate in markets that have not yet been established. Small company securities tend to be more volatile and less liquid than equity securities of larger companies.

Value Investing Risk. The prices of value stocks may lag the stock market for long periods of time if the market fails to recognize ICON’s evaluation of the company’s intrinsic worth.

Active Management Risk. The Fund is subject to the risk that the investment adviser’s judgments about the attractiveness, value, or potential appreciation of the Fund’s investments may prove to be incorrect. If the securities selected and strategies employed by the Fund fail to produce the intended results, the Fund could underperform other funds with similar objectives and investment strategies.

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 broader 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 the 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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that
issued them, general market and economic conditions, and investor confidence.

Performance History

A comparison of the Fund’s performance with that of an unmanaged securities index may illustrate the potential risks of an investment in the Fund; however, the Fund commenced operations on October 1, 2012 and does not have performance history for a full calendar year. Once the Fund has performance history, its past performance, before and after taxes, will not provide a guarantee of future results.

[1] ICON Advisers has contractually agreed to limit the total expenses of the Fund (excluding interest, taxes, brokerage and extraordinary expenses) to an annual rate of 1.50%. This expense limitation may be terminated at any time after January 31, 2014 upon 30 days written notice of termination to the Fund’s Board of Trustees. ICON is entitled to reimbursement from the Fund of any fees waived pursuant to this arrangement if such reimbursement does not cause the Fund to exceed existing expense limitations and the reimbursement is made within three years after the expenses were reimbursed or absorbed.

It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of companies in the Financial sector (as determined by the Global Industry Classification Standard) including, but not limited to: Asset Management & Custody Banks, Consumer Finance, Diversified Banks, Diversified Capital Markets, Diversified Real Estate Activities, Diversified REITs, Industrial REITs, Insurance Brokers, Investment Banking & Brokerage, Life & Health Insurance, Mortgage REITs, Multi-line Insurance, Multi-sector Holdings, Office REITs, Other Diversified Financial Services, Property & Casualty Insurance, Real Estate Development, Real Estate Operating Companies, Real Estate Services, Regional Banks, Reinsurance, Residential REITs, Retail REITs, Specialized Finance, Specialized REITs and Thrifts & Mortgage Finance.

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 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 Financial sector, which causes the Fund’s performance to be susceptible to the economic, business or other developments that affect those industries. For example, interest rate fluctuations, general economic conditions, the availability and cost of capital, natural disasters and changes in government regulation and legislation may impact the performance of the Fund. Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example ICON Risk-Managed Balanced Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	811	1,016	1,336	2,413
Class C	326	697	1,194	2,816
Class S	126	393	680	1,654

You would pay the following expenses if you did not redeem your Class C shares:

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 71.06% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON believes are underpriced relative to value. It seeks modest capital appreciation by normally investing at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities traded in U.S. markets, including common stocks and preferred stocks of any market capitalization. To manage the risk of holding equity securities, the Fund may write call options or purchase puts on the securities in the portfolio or indexes. The Fund may also purchase exchange traded funds and other derivatives.

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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. ICON's combination of industry rotation and bottom-up valuation distinguishes us from other investment managers. The Fund may invest up to 20% of its net assets in a broad range of investment grade U.S. dollar denominated bonds.

Principal Investment Risks

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

Correlation Risk. The effectiveness of the Fund's index option-based risk management strategy may be reduced if the performance of the Fund's equity portfolio does not correlate to that of the index underlying its option positions.

Options Risk. Investments in call 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.

• 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 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 usually 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.

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.

Bond Risk. Up to 20% of the Fund's net assets may be invested in a broad range of investment grade U.S. dollar denominated bonds, including corporate, agency and government-issued bonds. 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.

Small and Mid-Size Company Risk. The Fund may invest in small or mid-size companies, which may involve greater risk of loss and price fluctuation than larger and more established companies. The trading markets for securities of small-cap issuers may be less liquid and more volatile than securities of larger companies. This means that the Fund could have greater difficulty buying or selling a security of a small-cap issuer at an acceptable price, especially in periods of market volatility.

Foreign Investment Risk. Up to 20% of the Fund's net assets may be invested in foreign securities. 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 than U.S. stock markets.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

Segregated Account Risk. The Fund is required to maintain a segregated account of cash or highly liquid securities with a broker or custodian to cover the Fund's options positions. Securities held in a segregated account cannot be sold while the position they are covering is outstanding, unless they are replaced with similar securities. As a result, there is the possibility that segregation of a large percentage of the Fund's assets could affect its portfolio management.

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 54.26% of the average value of the portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON believes are underpriced relative to value. It normally invests in equity securities of companies of any market capitalization and traded in U.S. markets. The Fund will generally take long positions in equity securities identified as undervalued and take short positions in equity securities identified as overvalued. This strategy may not be changed unless Fund shareholders are given at least 60 days' prior notice. Each long or short position will be determined by considering the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio.

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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. ICON's combination of industry rotation and bottom-up valuation distinguishes us from other investment managers.

Principal Investment Risks

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

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.

Segregated Account Risk. Until the Fund replaces a borrowed security, it is required to maintain a segregated account of cash or highly liquid securities with a broker or custodian to cover the Fund's short position. Securities held in a segregated account cannot be sold while the position they are covering is outstanding, unless they are replaced with similar securities. As a result, there is the possibility that segregation of a large percentage of the Fund's assets could affect its portfolio management.

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.

Foreign Investment Risk. Up to 20% of the Fund's net assets may be invested in foreign securities. 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 than U.S. stock markets.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example ICON Financial Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	839	1,107	1,492	2,568
Class C	354	4,279	6,922	10,212
Class S	142	441	761	1,669

You would pay the following expenses if you did not redeem your Class C shares:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
ICON Financial Fund Class C	254	4,279	6,922	10,212

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 95.47% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON 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 in the Financial sector (as determined by the Global Industry Classification Standard) including, but not limited to: Asset Management & Custody Banks, Consumer Finance, Diversified Banks, Diversified Capital Markets, Diversified Real Estate Activities, Diversified REITs, Industrial REITs, Insurance Brokers, Investment Banking & Brokerage, Life & Health Insurance, Mortgage REITs, Multi-line Insurance, Multi-sector Holdings, Office REITs, Other Diversified Financial Services, Property & Casualty Insurance, Real Estate Development, Real Estate Operating Companies, Real Estate Services, Regional Banks, Reinsurance, Residential REITs, Retail REITs, Specialized Finance, Specialized REITs and Thrifts & Mortgage Finance. 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

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 broader categories called sectors. The Fund overweights 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. For example, interest rate fluctuations, general economic conditions, the availability and cost of capital, natural disasters and changes in government regulation and legislation may impact the performance of the Fund.

Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in foreign equity securities in the Asia-Pacific Region. Foreign equity securities in the Asia-Pacific Region include securities of issuers, wherever organized, whose securities are traded principally on a recognized stock exchange or over-the-counter market in the countries listed in the Morgan Stanley Capital International (“MSCI”) All Country (“AC”) Asia-Pacific Index. The Asia-Pacific Region includes the following countries: Australia, China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, New Zealand, Philippines, Singapore, Taiwan and Thailand. This strategy may not be changed unless Fund shareholders are given at least 60 days’ prior notice. 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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. 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 and preferred stocks of companies of any market capitalization.
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: 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. Geographic Risk. The Fund will be more susceptible to the economic, market, regulatory, political, natural disasters and local risks of the Asia-Pacific region than a fund that is more geographically diversified. The Asia-Pacific region includes countries in all stages of economic development; however, it has a higher prevalence of “emerging market” countries as compared to other regions of the world. Such emerging countries can be characterized as having less-developed legal and financial structures, over-extensions of credit, currency devaluations and restrictions, high inflation and unemployment. The region has historically been highly dependent on global trade, with nations taking strong roles in both the importing and exporting of goods; such a relationship creates a risk with this dependency on global growth. The respective stock markets tend to have a larger prevalence of smaller companies which are inherently more volatile and less liquid than larger comparables. Varying levels of accounting and disclosure standards, restrictions on foreign ownership, minority ownership rights, and corporate governance standards are also common for the region. Non-Diversified Portfolio Risk. The ICON Asia-Pacific Region Fund is “non-diversified” which means that a Fund may own larger positions in a smaller number of securities than funds 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 fund. The Fund’s share prices may also be more volatile than those of a diversified fund. 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. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth. 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.

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. It seeks modest capital appreciation by normally investing at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities traded in U.S. markets, including common stocks and preferred stocks of any market capitalization. To manage the risk of holding equity securities, the Fund may write call options or purchase puts on the securities in the portfolio or indexes. The Fund may also purchase exchange traded funds and other derivatives. 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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. ICON's combination of industry rotation and bottom-up valuation distinguishes us from other investment managers. The Fund may invest up to 20% of its net assets in a broad range of investment grade U.S. dollar denominated bonds.
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: Correlation Risk. The effectiveness of the Fund's index option-based risk management strategy may be reduced if the performance of the Fund's equity portfolio does not correlate to that of the index underlying its option positions. Options Risk. Investments in call 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. 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 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 usually 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. 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. Bond Risk. Up to 20% of the Fund's net assets may be invested in a broad range of investment grade U.S. dollar denominated bonds, including corporate, agency and government-issued bonds. 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. Small and Mid-Size Company Risk. The Fund may invest in small or mid-size companies, which may involve greater risk of loss and price fluctuation than larger and more established companies. The trading markets for securities of small-cap issuers may be less liquid and more volatile than securities of larger companies. This means that the Fund could have greater difficulty buying or selling a security of a small-cap issuer at an acceptable price, especially in periods of market volatility. Foreign Investment Risk. Up to 20% of the Fund's net assets may be invested in foreign securities. 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 than U.S. stock markets. Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth. Segregated Account Risk. The Fund is required to maintain a segregated account of cash or highly liquid securities with a broker or custodian to cover the Fund's options positions. Securities held in a segregated account cannot be sold while the position they are covering is outstanding, unless they are replaced with similar securities. As a result, there is the possibility that segregation of a large percentage of the Fund's assets could affect its portfolio management.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example ICON Equity Income Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	808	1,007	1,321	2,271
Class C	323	688	1,179	2,639
Class S	123	384	665	1,537

You would pay the following expenses if you did not redeem your Class C shares:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
ICON Equity Income Fund Class C	223	688	1,179	2,639

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 122.39% of the average value of the portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON 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 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.

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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. ICON’s combination of industry rotation and bottom-up valuation distinguishes us from other investment managers. The Fund generally invests 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 lower-rated securities.

Principal Investment Risks

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

Credit Risk. The Fund could lose money if the issuer of a 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 convertible security can cause a convertible security’s price to fall, potentially lowering the Fund’s share price.

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.

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.

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.

Stock Market Risk. The value of the stocks and other securities owned by the Fund will fluctuate depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence. The market also may fail to recognize the intrinsic worth of an investment or ICON may misgauge that worth.

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.

Government Agency Securities Risk. Securities issued by U.S. government agencies or government-sponsored enterprises may not be guaranteed by the U.S. Treasury. Government National Mortgage Association (“Ginnie Mae”) is authorized to guarantee, with the full faith and credit of the U.S. government, the timely payment of principal and interest on securities issued by institutions approved by Ginnie Mae and backed by pools of mortgages insured by the Federal Housing Administration or guaranteed by the Department of Veteran Affairs. Government-related guarantors are not backed by the full faith and credit of the U.S. government and include the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Pass-through securities issued by Fannie Mae are guaranteed as to timely payment of principal and interest by Fannie Mae, but are not backed by the full faith and credit of the U.S. government. Freddie Mac guarantees the timely payment of interest and ultimate collection of principal, but its participation certificates are not backed by the full faith and credit of the U.S. government.

Foreign Investment Risk. Up to 20% of the Fund’s net assets may be invested in foreign securities. 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 than U.S. stock markets.

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 121.82% of the average value of its whole portfolio.

Principal Investment Strategies.

The Fund uses a quantitative methodology to identify securities ICON believes are underpriced relative to value. It normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in foreign equity securities. Foreign equity securities refer to securities of issuers, wherever organized, whose securities are listed or traded principally on a recognized stock exchange or over-the-counter market outside the United States. This strategy may not be changed unless Fund shareholders are given at least 60 days’ prior notice.

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 industries ICON believes are overpriced and buy industries we believe are underpriced. The Fund may invest up to 25% of its assets in a single industry. 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 and preferred stocks of companies of any market capitalization.

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 broader categories called sectors. The Fund overweights 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. For example, the Fund’s performance may be impacted by general economic conditions, product cycles, competition, and government regulation. In addition, technological services and products are subject to rapid obsolescence which may lower the market value of the securities in the sector. Non-Diversified Portfolio Risk. The Fund is “non-diversified” which means that 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 involve greater risk of loss and price fluctuation.
