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.During the period from inception (December 18, 2012) through its fiscal year end (September 30, 2013), the fund's portfolio turnover rate was 115% of the average value of its portfolio.

Generally, Class A Shares are not subject to any charges by the Fund when redeemed; however, a contingent deferred sales charge may be imposed on certain redemptions (i) within 18 months on exchanges from a Virtus non-money market fund into a Virtus money market fund; and (ii) on purchases on which a finder's fee has been paid. The 18-month period begins on the last day of the month preceding the month in which the purchase was made. The deferred sales charge is imposed on Class C Shares redeemed during the first year only.

Example

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

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 that 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 and that the expense reimbursement arrangement remains in place only for the period indicated. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]

Investments, Risks and Performance

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The fund seeks to outperform the MSCI EAFE® Index over a full market cycle by tactically allocating net assets among countries included in the MSCI EAFE® Index. In pursuing this strategy, the fund maintains an emphasis on preservation of capital.

Allocations are based on a quantitative model that provides a positive or negative signal, on a weekly basis, for each country evaluated. Countries with positive signals will receive allocations approximating their relative weights in the MSCI EAFE® Index. The remaining portfolio assets will be allocated to the subadviser’s “minimum volatility portfolio,” which is designed to limit downside risk. The minimum volatility portfolio is allocated equally among the four countries that, in the subadviser’s opinion, have exhibited the lowest volatility pattern historically. To mitigate concentration, geographic, and political risk, the four countries in the minimum volatility portfolio cannot be from the same geographic or political region.

Each allocation may be invested in ETFs and/or baskets of securities representative of such ETFs. The fund may invest in a basket of securities to represent an ETF if it determines that investment in the ETF is not feasible or otherwise not in the best interest of the fund. The fund may invest in issuers of any capitalization.

Risk [Heading]

rr_RiskHeading

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The fund may not achieve its objective, and it is not intended to be a complete investment program. The value of the fund’s investments that supports your share value may decrease. If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money. Investment values can decrease for a number of reasons. Conditions affecting the overall economy, specific industries or companies in which the fund invests can be worse than expected, and investments may fail to perform as the subadviser expects. As a result, the value of your shares may decrease. Purchase and redemption activities by fund shareholders may impact the management of the fund and its ability to achieve its investment objective(s). The redemption by one or more large shareholders or groups of shareholders of their holdings in the fund could have an adverse impact on the remaining shareholders in the fund including by accelerating the realization of capital gains and increasing the fund's transaction costs. In addition, you will also be subject to the risks associated with the principal investment strategies of any ETFs in which the fund invests. The principal risks of investing in the fund are:

Equity Securities Risk. The risk that events negatively affecting issuers, industries or financial markets in which the fund invests, will impact the value of the stocks held by the fund and thus, the value of the fund’s shares over short or extended periods. Investments in a particular style or in small or medium-sized companies may enhance that risk.

Exchange-Traded Funds (ETFs) Risk. The risk that the value of an ETF will be more volatile than the underlying portfolio of securities the ETF is designed to track, or that the costs to the fund of owning shares of the ETF will exceed those the fund would incur by investing in such securities directly.

Foreign Investing Risk. The risk that the prices of foreign securities in the fund’s portfolio will be more volatile than those of domestic securities, or will be negatively affected by currency fluctuations or economic, political or other developments.

Fund of Funds Risk. The risk that the underlying funds in which the fund invests will expose the fund to negative performance and additional expenses associated with investment in such funds, and increased volatility.

Market Volatility Risk. The risk that the value of the securities in which the fund invests may go up or down in response to the prospects of individual companies and/or general economic conditions. Price changes may be temporary or may last for extended periods.

Model Portfolio Risk. The risk that investments selected using quantitative models may perform differently from the market as a whole or from their expected performance. There can be no assurance that use of a quantitative model will enable the fund to achieve positive returns or outperform the market.

Portfolio Turnover Risk. The risk that the fund’s principal investment strategies will result in a consistently high portfolio turnover rate. See the Portfolio Turnover section above for more information about the impact that portfolio turnover can have on fund performance.

Small and Medium Market Capitalization Risk. The risk that the fund’s investments in small and medium market capitalization companies will increase the volatility and risk of loss to the fund, as compared with investments in larger, more established companies.

Risk Lose Money [Text]

If between the time you purchase shares and the time you sell shares the value of the fund’s investments decreases, you will lose money.
