The Fund defines equity securities to include ETFs that invest primarily in equity securities, such as common and preferred stocks. The Fund defines fixed-income securities to include ETFs that invest primarily in fixed-income securities, such as bonds, notes and debentures. Pursuant to the Fund?s principal investment strategies, the Fund invests its assets in equity and fixed income ETFs that each invest primarily in domestic issuers of varying market capitalizations. While the Fund expects to primarily hold equity securities, it may reduce its equity security exposure and may, from time to time, not have any investment exposure to equity securities, depending on market conditions. With respect to fixed income securities, the Fund invests primarily in those rated BBB- or higher by Standard and Poor?s Rating Group or similarly rated by another nationally recognized statistical rating organization (?NRSRO?). The Fund may invest in fixed income securities of any credit quality (including high yield or ?junk? bonds) and any maturity. Under normal market conditions, the Fund invests at least 80% of its assets (defined as net assets plus any borrowing for investment purposes) measured at the time of purchase in ETFs. The Fund is named to reflect its investment strategy ?sector allocation.? The Fund?s adviser seeks capital appreciation through a tactical asset allocation strategy based on its proprietary macroeconomic model and investment philosophy that it believes have the potential to generate positive returns and manage risk in the given economic environment. The adviser?s investment model, which looks at the GICS universe of sectors to measure quantitative data, focuses on identifying the relative strength of various market sectors by analyzing data inputs including: (1) employment, (2) economic output (through gross domestic product or GDP), as well as (3) overall market conditions (such as price momentum). Based upon the inputs, the adviser seeks to overweight the sectors with the strongest economic and market signals while holding underweight allocations for the weaker sectors. The adviser tactically allocates assets among various sectors and market segments to rebalance the Fund?s investment portfolio according to the economic environment with the goal of achieving capital appreciation and lower drawdowns throughout full economic cycles. The adviser anticipates rebalancing the Fund?s portfolio based upon the adviser?s determination of changes in the economic cycle as well as other proprietary indicators. By balancing the Fund?s portfolio based on economic cycles, the adviser seeks to invest in those sectors and market categories with the highest potential for positive returns during periods of relative economic strength while de-allocating from equities and utilizing defensive positioning such as allocations to cash and fixed-income ETFs when economic and market environments weaken. In managing the Fund?s portfolio, the adviser may engage in frequent portfolio transactions, resulting in a high portfolio turnover rate. Show less
