Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to track the returns of the CEMP U.S. Small Cap 500 Long/Cash Volatility Weighted Index (the “Index”) before fees and expenses.  The Fund employs a replication strategy that entails holding all, or approximately all, the stocks in the Index.

The Index is an unmanaged index that was created by the Fund’s investment advisor and generally consists of the common stock of the 500 largest companies by market capitalization that have their headquarters in the U.S., market capitalizations of less than $3 billion, and the stock of which trades on a U.S. exchange.  The Index may include less than 500 stocks depending on the number of companies meeting the Index’s criteria.  The Index includes only companies with consistent positive earnings (at least its 4 most recent quarters) and is weighted based on the volatility of each stock.  Volatility is the extent to which the return of a security fluctuates between its highest price and its lowest price within a given period.  The weight of each member in the Index is defined by its own volatility relative to the average volatility of all Index members measured over the past 180 trading days.  Stocks with lower volatility receive a higher weighting and stocks with higher volatility receive a lower weighting.  The Index’s stock component is reconstituted every March and September and is adjusted to limit exposure to any particular sector to 25%.

The Index seeks to limit risk during unfavorable (non-normal) market conditions by reducing its exposure to the market. Market conditions are measured by reference to the CEMP U.S. Small Cap 500 Volatility Weighted Index. During a period of market decline, defined as a 10% drop from the all-time daily high and based on the month end value of the CEMP U.S. Small Cap 500 Volatility Weighted Index, exposure to the market may be as low as 25% depending on the magnitude and duration of such decline. The Index will return to being fully invested if the month end value of the stocks in the CEMP U.S. Small Cap 500 Volatility Weighted Index returns to a -10% value from its daily high. However, if the CEMP U.S. Small Cap 500 Volatility Weighted Index declines further to -20% from its recent highest value, 25% of the Index will be reinvested from cash equivalents back into the stocks of the CEMP U.S. Small Cap 500 Volatility Weighted Index at their current securities weighting. If the CEMP U.S. Small Cap 500 Volatility Weighted Index declines still further to -30% from the recent highest value, another 25% of the Index will be reinvested back into the stocks of the CEMP U.S. Small Cap 500 Volatility Weighted Index at their current securities weighting. If the CEMP U.S. Small Cap 500 Volatility Weighted Index declines even further to -40% (or more) from the recent highest value, the remaining 25% of the Index will be reinvested back into the stocks of the CEMP U.S. Small Cap 500 Volatility Weighted Index at their current securities weighting and the Index will then be 100% invested in stocks. The Index’s exposure to the market is dictated by a mathematical index construction algorithm, which is not subject to discretionary human judgment or intervention. Under normal market conditions, the Fund invests at least 80% of its assets (defined as net assets plus any borrowing for investment purposes) in securities of U.S. issuers included in the Index as of its most recent reconstitution.

During unfavorable market conditions the Fund will invest its cash in excess of the amount required for equity investments primarily in fixed income securities, including U.S. Treasury bills and notes, commercial paper and corporate bonds. With respect to such excess cash investments, the Fund expects the dollar-weighted average fixed income maturity to be 12 months or less and the credit quality of such securities to be primarily investment grade (defined as having a rating of BBB- and above). However, up to 20% of the fixed income portfolio may be composed of lower-quality corporate bonds rated B- or higher, which are commonly referred to as “junk bonds.”

Principal Risks of Investing in the Fund

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The following summarizes the principal investment risks of the Fund. Shares will change in value, and you could lose money by investing in the Fund.  The Fund may not achieve its investment objective and an investment in the Fund is not by itself a complete or balanced investment program.

· ETF Structure Risks.  The Fund is structured as an ETF and as a result is subject to special risks, including:

o   Not Individually Redeemable.  Shares are not individually redeemable and may be redeemed by the Fund at its net asset value per share (“NAV”) only in large blocks known as “Creation Units.”  You may incur brokerage costs purchasing enough Shares to constitute a Creation Unit.

o   Trading Issues.  Trading in Shares on the Exchange (as defined below) may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility.  There can be no assurance that Shares will continue to meet the listing requirements of the Exchange.  There is no guarantee that an active secondary market will develop for Shares of the Fund.

o   Market Price Variance Risk.  The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security.  There may be times when the market price and the NAV vary significantly.  This means that Shares may trade at a discount to NAV.

· Fixed Income Risk. The value of the Fund’s investments in fixed income securities will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities owned by the Fund. On the other hand, if rates fall, the value of the fixed income securities generally increases. The value of fixed income securities typically falls when an issuer’s credit quality declines and may even become worthless if an issuer defaults.

· Index Risk. Because the Index’s allocation to cash versus securities may be reallocated monthly, there is a risk that the Index will not be able to immediately react to changes in market conditions that occur between reallocations.

· Junk Bond Risk.  Lower-quality fixed income securities, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default.  These securities are considered speculative.

· Limited History of Operations.  The Fund is a new exchange traded fund (“ETF”) and has a limited history of operations for investors to evaluate.

· Passive Investment Risk.  The Fund is not actively managed and the Advisor will not sell shares of an equity security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a rebalancing of the Index as addressed in the Index methodology.

· Small Capitalization Stock Risk.  The earnings and prospects of smaller-sized companies are more volatile than larger companies and may experience higher failure rates than larger companies.  Smaller-sized companies normally have a lower trading volume than larger companies, which may tend to make their market price fall disproportionately more than larger companies in response to selling pressures and may have limited markets, product lines, or financial resources and lack management experience.

· Stock Market Risk. Overall stock market risks may 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.

· Tracking Risks. The Fund’s return may not match the return of the Index for a number of reasons, including: the Fund incurs operating expenses not applicable to the Index, and incurs costs in buying and selling securities; the Fund may not be fully invested at times; the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund’s portfolio and the Index resulting from legal restrictions, cost or liquidity constraints.
