Portfolio Turnover:
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. The Fund’s portfolio turnover rate was 85% of the average value of its portfolio for the fiscal year ending April 30, 2016.

This Example does not reflect the effect of brokerage commissions or other transaction costs you pay in connection with the purchase or sale of Fund shares. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same and the expense reduction/reimbursement remains in place for the contractual period only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Principal Investment Strategy
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is an actively managed exchange-traded fund (“ETF”) that, under normal conditions, will invest primarily in U.S. common stock, exchange traded funds (“ETFs”) and exchange traded notes (“ETNs”). Under normal circumstances, at least 80% of the Fund’s net assets, plus any borrowings for investment purposes, will be invested in securities of U.S. companies or in other investment companies that principally invest in such securities. The Fund may also invest in foreign companies traded on a U.S. exchange (including American Depositary Receipts). The Fund’s portfolio is composed of two components: (i) the common stock component and (ii) the tactical component. The Fund’s assets may be invested in either of these two components without limit.

 

The Common Stock Component.

 

The Common Stock Component of the Fund’s portfolio will invest in companies within each of the large-cap, mid-cap and small-cap U.S. equity segments (each a “Market Segment”) that operate in each of the ten (10) sectors represented in the S&P Composite 1500Ò. A sector is a large grouping of companies operating within the market that share similar characteristics. The ten (10) sectors comprising the S&P Composite 1500Ò are: utilities, consumer staples, information technology, healthcare, financials, energy, consumer discretionary, materials, industrials, and telecommunications services (“Sectors”). The S&P Composite 1500 is comprised of the S&P 500®, the S&P MidCap 400® and S&P SmallCap 600®.

 

As market conditions change, the Fund intends to rotate the investment focus of the Fund so as to overweight its portfolio in companies comprising those Market Segments and Sectors that the Advisor believes offer the greatest potential for capital appreciation in the given market environment and underweight its portfolio in those Market Segments and Sectors that the Advisor believes offer the least potential for capital appreciation in that same market environment. If the Fund’s portfolio allocation to a particular Market Segment or Sector exceeds that Market Segment’s or Sector’s current weighting in the S&P Composite 1500, then the Fund will be “overweighting” that Market Segment or Sector. Similarly, if the Fund’s portfolio allocation to a specific Market Segment or Sector is less than that Market Segment’s or Sector’s current weighting in the S&P Composite 1500, then the Fund will be “underweighting” that Market Segment or Sector. The Advisor believes that these adjustments, collectively, will position the Fund for continued capital appreciation in the new market environment.

 

The Common Stock of the Fund’s portfolio is created using two proprietary quantitative strategies. The first strategy identifies and evaluates various factors including value, momentum, smart money (ex. tracking insider and institutional buying and selling), profitability, trading friction (ex. volume, price and beta) and growth. The second strategy utilizes a multi-factor model which analyze earnings, technical factors, valuations and industry leadership.

 

The Advisor retains a broad mandate and discretion to invest in companies consistent with its evaluation of the capital appreciation potential of the Market Segments and Sectors. The strategy of overweighting and underweighting Sectors to maximize opportunities for capital appreciation may result in the Fund investing greater than 25% of its total assets in the equity securities of companies operating in one or more Sectors. Sectors are comprised of multiple individual industries. The Fund will not invest more than 25% of its total assets in an individual industry.

 

Both in current market conditions and, more importantly, over longer time periods, the Advisor believes that investing in companies consistent with its ongoing evaluation of the capital appreciation potential of the Market Segments and Sectors is intrinsic to maximizing performance in the domestic equity markets.

 

The Tactical Component

 

The Tactical Component of the Fund’s portfolio invests in actively managed or index equity-based ETFs and ETNs. This portion of the Fund’s portfolio may also invest in treasury, fixed income, volatility and commodity ETFs and ETNs. The Fund may invest in fixed income ETFs and ETNs that principally invest in investment grade securities of any duration or maturity. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates. For example, if a bond has a duration of 5 years, a 1% rise in rates would result in a 5% decline in share price. If a bond has a duration of 10 years, a 1% rise in interest rates would result in a 10% decline in share price. The goal of this component of the Fund’s portfolio is to be opportunistic during market rallies and move into defensive positions during market declines though the use of three tactical strategies:

 

Trend Following---The trend following models seeks to identify strong sectors to buy and weak sectors to sell. Trend following is based on the idea that strong areas of the market will remain strong and weak areas will remain weak.

 

Mean Reversion---The mean reversion models look for strong sectors that appear overbought to sell and weak sectors that appear oversold to buy. Mean reversion is based on the idea that market sectors often become overextended on the upside and downside before ultimately snapping back to equilibrium.

 

Intermarket Analysis---These models will analyze market sectors that are correlated or uncorrelated and look for divergences. These divergences often signal major market turning points.

 

The Fund actively trades its portfolio securities in an attempt to achieve its investment objective.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration Under normal circumstances, at least 80% of the Fund’s net assets, plus any borrowings for investment purposes, will be invested in securities of U.S. companies or in other investment companies that principally invest in such securities.
Risk [Heading] rr_RiskHeading

Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

All ETFs, including the Fund, take investment risks. Therefore, it is possible to lose money by investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The primary factors that may reduce the Fund’s net asset value per share (“NAV”), market price per share and returns include:

 

Active Trading Risk. The Fund may trade securities actively, which could increase its transaction costs (thereby lowering its performance) and could increase the amount of taxes you owe by generating short-term gains, which may be taxed at a higher rate.

 

Commodities Risk. Investing in the commodities markets (directly or indirectly) may subject the Fund to greater volatility than investments in traditional securities. Commodity prices may be influenced by unfavorable weather, animal and plant disease, geologic and environmental factors as well as changes in government regulation such as tariffs, embargoes or burdensome production rules and restrictions.

 

Equity Securities Risk. The price of equity securities in the Fund’s portfolio will fluctuate based on changes in a company’s financial condition and on market and economic conditions.

 

ETF Risk. The Fund is an actively-managed ETF and the Fund’s NAV will fluctuate based on changes in the prices of the securities it owns. The market price of Fund shares will fluctuate based on changes in the Fund’s NAV as well as changes in the supply and demand of its shares in the secondary market. It is also possible that an active secondary market for Fund shares may not develop and market trading in the Fund shares may be halted under certain circumstances. Shares of the Fund are not individually redeemable.

 

ETN Risk. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced commodity. The value of the ETN may drop due to a downgrade in the issuer’s credit rating, even if the underlying index remains unchanged. Investments in ETNs are subject to the risks facing income securities in general including the risk that a counterparty will fail to make payments when due or default.

 

Fixed Income Risk. The value of the Fund’s investments in fixed income securities may decline when prevailing interest rates rise or increase when interest rates fall. The longer a security’s maturity or duration, the greater its value will change in response to changes in interest rates. The interest earned on the Fund’s investments in fixed income securities may decline when prevailing interest rates fall.

 

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. To the extent foreign securities are denominated in foreign currencies, their values may be adversely affected by changes in currency exchange rates. All of the risks of investing in foreign securities are typically increased by investing in emerging market countries.

 

Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.

 

Large-Cap Stock Risk. The Fund’s investment in larger companies is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.

 

Management Risk. The Advisor may not successfully implement the Fund’s investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.

 

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s NAV or market price per share may decline suddenly or over a sustained period of time.

 

Market Price Variance Risk. There may be times when the market price per share and NAV of the Fund may vary significantly, and because most investors buy and sell shares of the Fund in the secondary market at market price, investors may pay more than NAV when buying Fund shares, and receive less than NAV when selling Fund shares. In addition, investors will incur certain transaction costs in purchasing and selling Fund shares in the secondary market.

 

Mid/Small-Cap Stock Risk. Because the smaller companies in which the Fund may invest may have unproven track records, a limited product or service base and limited access to capital, they may be more likely to fail than larger companies.

 

Sector Risk. If the Fund invests more than 25% of its total assets in securities of issuers within a particular Sector, it is subject to increased risk. Performance will generally depend on the performance of the Sector, which may differ in direction and degree from that of the overall U.S. stock markets. In addition, financial, economic, business and political developments affecting the Sector may have a greater effect on the Fund than they would if the Fund did not focus on that Sector.

 

Treasury Obligations Risk. Direct obligations of the U.S. Treasury have historically involved little risk of loss of principal if held to maturity. However, due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund.

 

Underlying Fund Risk. Other investment companies including ETFs (“Underlying Funds”) in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in the Underlying Funds and may be higher than other funds that invest directly in stocks and bonds. Each of the Underlying Funds is subject to its own specific risks, but the sub-adviser expects the principal investments risks of such Underlying Funds will be similar to the risks of investing in the Fund.

Principal Investment Strategy
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is an actively managed exchange-traded fund (“ETF”) and, under normal conditions, will invest at least 80% of its net assets (plus borrowings for investment purposes) in the exchange-listed equity securities of ecologically-focused companies.

 

The Fund will primarily invest (at least 65% of total assets) in the U.S. exchange-listed common stock of ecologically-focused companies organized in the U.S. (“U.S. Companies”). The Fund, however, may also invest up to 35% of total assets in the exchange-listed common stock (or the equivalent thereof) and sponsored American Depositary Receipts (“ADRs”) of ecologically-focused companies organized outside the U.S. (“Foreign Companies”). Sponsored ADRs are securities issued by a U.S. bank or trust company with the cooperation of a foreign company evidencing ownership of underlying securities issued by that foreign company. The Fund may invest in companies of all sizes.

 

The Advisor will apply the following ecologically-focused criteria to identify the equity securities of U.S. and Foreign Companies. Ecologically-focused companies are companies that have positioned their business to respond to increased environmental legislation, cultural shifts towards environmentally conscious consumption, and capital investments in environmentally oriented projects. These companies include, but are not limited to, all U.S. and Foreign Companies that are components of one or more well-recognized environmentally-focused indices (such as the Dow Jones Sustainability Indexes and the DB NASDAQ OMX Clean Tech Index).

 

The Fund will also invest in ecologically-focused companies which are not included in a well-recognized environmentally-focused index but generate at least ? of their revenues from activities aligned with one or more of the following environmental themes (“Environmental Themes”):

 

• Alternative renewable power such as solar, wind, geothermal, hydro or biomass;

 

• Alternative renewable fuel such as biofuel, biomass or hydrogen;

  

• Alternative engines such as electric, flywheel or micro turbines;

 

• Energy efficiency such as energy efficient building materials, power, lighting, heating, or fuel;

 

• Resource conservation/healthier use of resources such as recycling or renewable materials; and

 

• Healthy lifestyle such as pollution control or organic foods.

 

A company that is not included in a well-recognized environmentally-focused index or does not generate 1/3 of its revenue from activities aligned with one or more Environmental Themes shall also be considered an ecologically-focused company if the Advisor believes that environmentally conscious trends such as a stronger demand for chemical-free cleaning and farming, recycling, alternative fuel and energy, energy efficiency, pollution control, or environmental cleanup/restoration will positively impact that company’s future revenue (“Environmentally Conscious Companies”). Ecologically-focused companies also include those companies that the Advisor believes demonstrate sustainable environmental practices (“Other Environmental Companies”). Sustainable environmental practices include, but are not limited to, demonstrated progress in:

 

• Improving energy and resource efficiency;

 

• Reducing emissions from business operations;

 

• Financial and operational support of renewable materials and less polluted energy sources; or

 

• Using or promoting the use of efficient buildings (measured by such labels as LEED or Energy Star).

 

The Fund’s investment in the securities of Environmentally Conscious Companies and Other Environmental Companies will be limited to 10% of the Fund’s total assets.

 

The strategy of investing in ecologically-focused companies may result in the Fund investing greater than 25% of its total assets in one or more market sectors (“Sectors”). A Sector is a large grouping of companies operating within the market that share similar characteristics. The ten most commonly recognized market Sectors are: utilities, consumer staples, information technology, healthcare, financials, energy, consumer discretionary, materials, industrials, and telecommunication services. Sectors are comprised of multiple individual industries. The Fund will not invest more than 25% of its total assets in an individual industry as defined by the Standard Industrial Classification Codes utilized by the Division of Corporation Finance of the U.S. Securities and Exchange Commission.

 

The Fund actively trades its portfolio securities in an attempt to achieve its investment objective.

Principal Investment Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

All ETFs, including the Fund, take investment risks. Therefore, it is possible to lose money by investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The primary factors that may reduce the Fund’s net asset value per share (“NAV”), market price and returns include:

 

Active Trading Risk. The Fund may trade securities actively, which could increase its transaction costs (thereby lowering its performance) and could increase the amount of taxes you owe by generating short-term gains, which may be taxed at a higher rate.

 

Currency Risk. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

 

Ecological Investment Risk. The Fund’s ecological investment criteria limit the types of investments the Fund may make. This could cause the Fund to underperform other funds that do not have an ecological focus.

 

Equity Securities Risk. The price of equity securities in the Fund’s portfolio will fluctuate based on changes in a company’s financial condition and on market and economic conditions.

 

ETF Risk. The Fund is an actively-managed ETF and the Fund’s NAV will fluctuate based on changes in the prices of the securities it owns. The market price of Fund shares will fluctuate based on changes in the Fund’s NAV as well as changes in the supply and demand of its shares in the secondary market. It is also possible that an active secondary market for Fund shares may not develop and market trading in the Fund shares may be halted under certain circumstances. Individual shares of the Fund are not redeemable.

 

Foreign Custodial Services Risk. Custodial services are generally more expensive in foreign jurisdictions than in the U.S. In addition, because the procedures for settling securities transactions in foreign markets differ from those in the U.S., it may be more difficult for the Fund to make intended purchases and sales of securities in foreign countries.

 

Foreign Investment Risk. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. To the extent foreign securities are denominated in foreign currencies, their values may be adversely affected by changes in currency exchange rates. All of the risks of investing in foreign securities are typically increased by investing in emerging market countries.

 

Growth Investing Risk. The growth stocks in which the Fund invests are typically more volatile than value stocks and may depend more on price changes than dividends for return.

 

Investment Style Risk. The type of securities in which the Fund focuses may underperform other assets or the overall market.

 

Large-Cap Stock Risk. The Fund’s investment in larger companies is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.

 

Management Risk. The Advisor may not successfully implement the Fund’s investment strategies and, as a result, the Fund may not meet its investment objective and/or underperform other investment vehicles with similar investment objectives and strategies.

 

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s NAV or market price per share may decline suddenly or over a sustained period of time.

 

Market Price Variance Risk. There may be times when the market price per share and NAV of the Fund may vary significantly, and because most investors buy and sell shares of the Fund in the secondary market at market price, investors may pay more than NAV when buying Fund shares, and receive less than NAV when selling Fund shares. In addition, investors will incur certain transaction costs in purchasing and selling Fund shares in the secondary market.

 

Mid/Small-Cap Stock Risk. Because the smaller companies in which the Fund may invest may have unproven track records, a limited product or service base and limited access to capital, they may be more likely to fail than larger companies.

 

Sector Risk. If the Fund invests more than 25% of its total assets in securities of issuers within a particular Sector, it is subject to increased risk. Performance will generally depend on the performance of the Sector, which may differ in direction and degree from that of the overall U.S. stock markets. In addition, financial, economic, business and political developments affecting the Sector may have a greater effect on the Fund than they would if the Fund did not focus on that Sector.

[2] Acquired Fund Fees and Expenses are the indirect costs of investing in other investment companies. The total annual fund operating expenses in this fee table will not correlate to the expense ratio in the Fund’s financial highlights because the financial statements include only the direct operating expenses incurred by the Fund, not the indirect costs of investing in other investment companies.

The Expense Cap will remain in effect until at least August 31, 2017. The Expense Cap may be terminated earlier only upon the approval of the Board.
