Portfolio Turnover

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover 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.

Strategy Narrative [Text Block]

The Fund seeks to achieve its investment objective by investing primarily in common stocks and options of U.S. companies. The Fund will take long positions in stocks that are experiencing significant insider buying and take counteracting short positions, primarily through selling stocks short and buying put options, in those companies that are experiencing significant insider selling. The Fund may invest in companies of any market capitalization, including smaller-sized companies.

The Advisor uses public information on insider buying and selling activity for its investment decisions. The Advisor’s research and quantitative back testing of insider trading data over long periods of time has resulted in the development of a proprietary method of analyzing insider trading activity that it believes can provide long term capital appreciation with low volatility and low correlation to the general equity markets. The Fund’s investment process focuses on insider identities (position in the company), motivations, insider trading trends, trading volumes, firm size and other factors to select stocks for long and short positions. Long positions are sold and short positions are covered (bought back) when the relevant insider trading trends reverse or when portfolio positions achieve or no longer provide the targeted risk adjusted return.

The Fund is classified as “non-diversified” for purposes of the Investment Company Act of 1940 (the “1940 Act”), which means that it is not limited by the 1940 Act with regard to the portion of its assets that may be invested in the securities of a single issuer.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any mutual fund, there is no guarantee that the Fund will achieve its goal. The Fund's net asset value and returns will vary and you could lose money on your investment in the Fund.

Limited History of Operations. The Fund is a new or relatively new mutual fund and has a limited history of operations.

Management Risk. The portfolio manager’s judgments about the attractiveness, value and potential appreciation of particular stocks or other securities in which the Fund invests may prove to be incorrect and there is no guarantee that the portfolio manager’s judgment will produce the desired results.

Market Risk. Overall stock market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels and political events affect the securities markets.

Non-diversification Risk. Because a relatively high percentage of a non-diversified Fund’s assets may be invested in the securities of a limited number of companies that could be in the same or related economic sectors, the Fund’s portfolio may be more susceptible to any single economic, technological or regulatory occurrence than the portfolio of a diversified fund.

Options Risk. There are risks associated with the sale and purchase of call and put options. As the buyer of a put option, the Fund assumes the risk of a rise in the market price of the underlying security above the exercise price of the option which will cause a loss of the premium paid for the option.

Security Risk. The value of the Fund may decrease in response to the activities and financial prospects of an individual security in the Fund’s portfolio.

Short Selling 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. The Fund may not be able to successfully implement its short sale strategy due to limited availability of desired securities or for other reasons.

Smaller Capitalization Stock Risk. To the extent the Fund invests in the stocks of smaller-sized companies, the Fund may be subject to additional risks, including the risk that earnings and prospects of these companies are more volatile than larger companies. Smaller-sized companies may experience higher failure rates than larger companies and normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objectives by tactically allocating and re-balancing its portfolio among domestic equity and fixed income securities. The Fund's sub-advisor uses a proprietary quantitative tactical allocation model to evaluate the relative attractiveness of equity and fixed income market sectors. This model uses a combination of price momentum, current price relative to long-term moving averages, relative strength of price trend and other price history-based inputs to generate buy and sell signals. The model signals increasing equity allocation during sustained rallies and signals increasing fixed income allocation, when weaker equity markets are anticipated.

The allocation of the Fund's investments are expected to track the sub-advisor's tactical allocation model. Asset allocation is evaluated and rebalanced on a monthly basis based on the model's calculation of the yield curve for bonds (the relationship between interest rates and bond maturities) and the risk premium for equities. The tactical allocation strategy is designed to signal avoiding equity investments during periods in which equities are expected to significantly underperform fixed income investments. When the model's inputs reach certain thresholds, the model will signal a complete move either out of stocks and into bonds or out of bonds and into stocks, as appropriate.

The model's default state (i.e., when equities are not expected to significantly underperform fixed income investments) is to allocate assets to equities. To select specific stocks, the sub-advisor uses a proprietary stock selection model that ranks stocks according to fundamental criteria that the sub-advisor believes are indicative of both company strength and relative value. These criteria include market capitalization, sector, dividend yield, earnings, cash flow and return on capital. Stocks are sold either when indicated by the stock selection model or when the risk model signals a move out of stocks and into bonds.

When the tactical allocation model signals a move from stocks to bonds, all equity allocations are sold and equal-weight allocations are made to a group of exchange traded funds (ETFs) that invest in bonds. These fixed income positions are sold when the risk model signals a move out of bonds and into stocks.

The Fund may invest in common stock, or ETFs investing in common stock, of companies of any market capitalization, but has a concentration in medium and large capitalization companies. Likewise, the Fund may invest in any domestic fixed income or bond ETF, but will be invested primarily in short-term and intermediate-term U.S. Treasury obligation ETFs. The Fund may also purchase put options on both equity index and fixed income ETFs in an effort to hedge against downside price risk.

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any mutual fund, there is no guarantee that the Fund will achieve its goal. The Fund's net asset value and returns will vary and you could lose money on your investment in the Fund.

Acquired Fund Risk. Because the Fund invests in other investment companies such as ETFs, the value of your investment will fluctuate in response to the performance of the acquired funds. Investing in acquired funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the securities of the acquired funds.

Interest Rate Risk. Interest rate risk is the risk that bond prices overall, including the prices of securities held by the Fund, will decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. When the Fund invests in acquired funds that invest in fixed-income securities, the value of your investment in the Fund will generally decline when interest rates rise.

Limited History of Operations. The Fund is a new or relatively new mutual fund and has a limited history of operations.

Management Risk. The portfolio manager’s judgments about the attractiveness, value and potential appreciation of particular stocks or other securities in which the Fund invests may prove to be incorrect and there is no guarantee that the portfolio manager’s judgment will produce the desired results.

Market Risk. Overall stock market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels and political events affect the securities markets.

The Fund seeks to achieve its investment objectives by investing in common stocks of U.S. companies and using options to generate premium income and hedge against downside risk. The Fund may invest in companies of any market capitalization, including smaller-sized companies, but invests primarily in medium and large capitalization stocks. The Fund will sell (write) put options on the same equity securities being purchased to generate premium income and to dollar-cost average equity purchases over time. The Fund may also purchase put options on underlying long positions in an effort to hedge against downside price risk.

Assets of the Fund are invested using a quantitative methodology followed by qualitative research. The quantitative analysis ranks stocks based on a combination of return on invested capital, earnings yield and free cash flow measures. Return on invested capital is the company's earnings as a percentage of the company's total assets. Earnings yield is the company's earnings per share as a percentage of the stock price. Free cash flow is operating cash flow less capital expenditures. This methodology generally results in a selection of profitable companies with relatively low price-to-earnings (P/E) ratios.

The highest scoring stocks from the quantitative analysis are then researched to identify which companies the portfolio managers believe have the best opportunity to maintain their financial performance and increase in value. Allocations for each of these stocks are then developed. A portion of each allocation may be used to purchase the stock as a long position and to purchase put options on the stock as a hedge against downside price risk. The balance of the allocation will be used as collateral against the sale of short-dated put options on the same stock to generate premium. As these puts expire, new short-dated put options will be sold (written) to generate additional premium. In the cases where sold puts are exercised, the Fund is forced to purchase a stock already being accumulated, and in most cases at a lower cost basis. In the event any put positions are converted through assignment into long stock positions, the Fund may purchase put options on the stock as a hedge against downside price risk.
