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 where 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 had a portfolio turnover rate of 367% for the fiscal year ended December 31, 2012.

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 Investor Class of 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% annual return and the fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your cost would be:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Adviser uses a matrix of "top-down" macro models and "bottom-up" micro stock selection models to determine weighting in countries, sectors and individual securities. The Adviser believes government policies are a precursor to change, and as a result, it monitors and tracks the fiscal and monetary policies of the world's largest countries both in terms of economic stature and population. The Adviser focuses on historical and socioeconomic cycles, and it applies both statistical and fundamental models, including "growth at a reasonable price" (GARP), to identify companies with superior growth and value metrics. The Adviser overlays these explicit knowledge models with the tacit knowledge obtained by domestic and global travel for first-hand observation of local and geopolitical conditions, as well as specific companies and projects.


The Adviser's "bottom-up" stock selection approach is generally characterized as growth at a reasonable price, which focuses on three key drivers: revenue growth, cash flow and return on equity. The Adviser searches for growth companies that have strong fundamentals and are also trading at reasonable valuations. The Adviser considers companies of all sizes when making stock selections, but its emphasis is on small- and mid-sized companies.


The Global Emerging Markets Fund invests, under normal market conditions, at least 80% of its net assets in equity and equity-related securities of companies located in emerging market countries or in companies with a significant business presence in emerging market countries. The equity and equity-related securities in which the fund primarily invests are common stocks, preferred stocks, convertible securities, rights and warrants, and depository receipts (ADRs and GDRs).


Emerging market countries are those countries defined as such by the World Bank, the International Finance Corporation, the United Nations or the European Bank for Reconstruction and Development or included in the MSCI Emerging Markets Index.


The fund will consider investments in an emerging market country to be the following:


1.  securities of issuers organized under the laws of any emerging market country or having a principal office in, an emerging market country;


2.  securities that are traded primarily in an emerging market country;


3.  securities of issuers that have a majority of their assets in an emerging market country; or


4.  securities of issuers that derive a majority of their revenues or profits from goods produced or sold, investments made or services performed in an emerging market country.


The fund may invest up to 20% of its net assets in securities, including debt securities, of governments and companies located anywhere in the world.


The fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.


The fund also may purchase call and put options, and enter into covered option writing transactions. In addition, the fund may invest up to 15% of its net assets in illiquid securities.


The Adviser uses a matrix of statistical models to monitor market volatility and money flows, and as a result, it may at times maintain higher than normal cash levels. For example, the Adviser may take a temporary defensive position when the securities trading markets or the economy are experiencing excessive volatility, a prolonged general decline, or other adverse conditions.

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

•  Main Risk. As with all mutual funds, loss of money is a risk of investing in the fund.


•  Market Risk. The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors affecting the securities market generally.


•  Portfolio Management Risk. The skill of the Adviser will play a significant role in the fund's ability to achieve its investment objectives. There is a risk that the investment strategy does not achieve the fund's objectives or that the Adviser does not implement the strategy properly.


•  Foreign Securities Risk/Emerging Markets Risk. The fund's investments in foreign securities are subject to special risks. The fund's returns and share price may be affected to a large degree by several factors, including fluctuations in currency exchange rates; political, social, or economic instability; the rule of law with respect to the recognition and protection of property rights; and less stringent accounting, disclosure, and financial reporting requirements in a particular country. These risks are generally intensified in emerging markets, which include those countries in which the fund primarily invests. The fund's share prices will reflect the movements of the different stock markets in which it is invested and the currencies in which its investments are denominated.


•  Sector Risk. The fund may invest a significant amount of its total assets in certain sectors, which may be subject to specific risks. These risks include governmental regulation of the sector and governmental monetary and fiscal policies which may negatively affect a particular sector. In addition, governmental policies towards international trade and tariffs may affect particular sectors.


•  Growth Stock Risk. Growth stocks generally experience share price fluctuations as the market reacts to changing perceptions of the underlying companies' growth potentials and broader economic activities.


•  Non-Diversification Risk. The fund is non-diversified and may invest a significant portion of its total assets in a small number of companies. This may cause the performance of the fund to be dependent upon the performance of one or more selected companies, which may increase the volatility of the fund.


•  Small- and Mid-Sized Companies Risk. The fund may invest in small- and mid-sized companies, which involve greater risk than investing in more established companies. This risk includes difficulty in obtaining reliable information and financial data and low liquidity in the market, making it difficult to dispose of shares when it may be otherwise advisable.


•  Options Risk. Investing in options, LEAPS (an option that has an expiration date of up to two and one half years), and other instruments with option-type elements may increase the volatility and/or transaction expenses of the fund. An option may expire without value, resulting in a loss of the fund's initial investment and may be less liquid and more volatile than an investment in the underlying securities.


•  Illiquidity Risk. Illiquid securities are those securities that cannot be disposed of in seven days or less at approximately the value at which a fund carries them on its balance sheet. These investments may involve a high degree of business and financial risk.

Risk Lose Money [Text] rr_RiskLoseMoney As with all mutual funds, loss of money is a risk of investing in the fund.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus The fund is non-diversified and may invest a significant portion of its total assets in a small number of companies. This may cause the performance of the fund to be dependent upon the performance of one or more selected companies, which may increase the volatility of the fund.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The following bar chart and table show the volatility of the fund's Investor Class share returns, which is one indicator of the risks of investing in the fund. The bar charts show changes in the fund's returns from year to year during the periods indicated. The table compares the fund's average annual returns for the last 1-year, 5-year and since inception periods to those of broad-based securities market indexes. How the fund performed in the past, before and after taxes, is not an indication of how it will perform in the future. You may obtain performance data current to the most recent month end at www.usfunds.com or by calling 1-800-873-8637.


On November 7, 2008, the Adviser took over the day-to-day management of the Global Emerging Markets Fund from the subadviser. Consequently, the fund's prior performance may have been different if the Adviser had been managing the fund.
