Summarize how the Fund intends to achieve its investment objectives by identifying the Fund's principal investment strategies (including the type or types of securities in which the Fund invests or will invest principally) and any policy to concentrate in securities of issuers in a particular industry or group of industries.Reference 1: 1 -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection a falsefalseStrategy [Heading]26false0rr_StrategyNarrativeTextBlockrrfalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00 The Portfolio's adviser seeks to achieve the Portfolio's investment objectives by allocating assets in a combination of (1) open-end investment companies (mutual funds), (2) exchange-traded funds ("ETFs"), (3) closed-end investment companies (collectively "Underlying Funds"), and (4) equity and debt securities, including American Depositary Receipts ("ADRs") using the adviser's proprietary technical and fundamental screening models. Although the Portfolio's strategy is focused primarily on the capital appreciation component of its total return objective, the income component of the objective is derived primarily from interest income from fixed income securities, and stock dividends. The phrase "risk-adjusted" in the Portfolio's objective refers to the goal of enhancing total return by reducing loses when markets are declining. The Portfolio defines equity securities as common and preferred stock, convertible securities, warrants, and ADRs for common and preferred stocks. The Portfolio may also take short positions in common stocks. The Portfolio's adviser selects securities from issuers of any market capitalization, credit quality or country. The Portfolio may invest in fixed income securities that are sometimes referred to as "high yield" or "junk" bonds. The Portfolio defines high yield bonds as those rated lower than Baa3 by Moody's Investors Service ("Moody's") or lower than BBB- by Standard and Poor's Rating Group ("S&P"), or if unrated, determined by the adviser to be of similar quality. Such securities are considered speculative investments that carry greater risk of default. The Underlying Funds include high beta index funds (“HBIFs”), which are mutual funds and ETFs that track an equity or fixed income index by investing in leveraged instruments such as equity index swaps, futures contracts and options on securities, futures contracts, and stock indices.  HBIFs are more volatile than the benchmark index they track and typically don’t invest directly in the securities included in the benchmark, or in the same proportion that those securities are represented in that benchmark. HBIFs seek to provide investment results that will match a certain percentage greater than 100% of the performance of a specific benchmark on a daily basis. For example, if a HBIF’s current benchmark is 200% of the S&P 500 Index and it meets its objective, the value of the HBIF will tend to increase on a daily basis 200% of any increase in the underlying index (if the S&P 500 Index goes up 5% then the HBIF’s value should go up 10%). When the value of the underlying index declines, the value of the HBIF’s shares should also decrease on a daily basis by 200% of the value of any decrease in the underlying index (if the S&P 500 Index goes down 5% then the value of the HBIF should go down 10%). ADRs are traded on U.S. exchanges and represent an ownership interest in a foreign security. They are generally issued by a U.S. bank or trust as a substitute for direct ownership of the foreign security.  The Portfolio typically will not invest directly in foreign securities, but will, in any case, limit such direct foreign investments to 25% of its net assets. The adviser uses proprietary models to determine the types and amounts of securities in the Portfolio’s portfolio. The models used are technical and fundamental. The technical models are proprietary trading strategies based on applying certain mathematical properties (such as linear regressions and weighted moving averages) to the value of a stock index (such as the S&P 500 or Russell 2000) or a bond category or index (such as inflation-protected securities, municipal bonds, or corporate bonds).  The technical models seek to invest in the market when the trends suggest lower risk and not invest in the market when the trends suggest higher risk.  The adviser uses the models to seek optimum returns relative to reduced risk for the Portfolio.  The fundamental models are proprietary trading strategies that search a monthly database of profit/loss and balance sheet figures to identify investment candidates.  Such figures include, but are not limited to, revenue, earnings, margins, total return, income and p/e ratio. The fundamental models are used to select all of the Portfolio’s direct investments in stocks, and the technical models are generally used to select Underlying Funds.  The proportion of Portfolio assets invested under either type of model will vary with the adviser’s investment allocation and risk reduction strategies, as well as with market conditions.  Generally, securities are purchased to fulfill the adviser's asset allocation targets and specific equity securities are selected based upon the adviser's fundamental screening criteria (e.g. revenue, earnings, margins, total return, income, p/e ratio, etc.).  Securities are sold when they no longer meet the adviser's fundamental criteria, stop-loss limits are reached, or to rebalance asset class allocations.  The adviser may sell common stock short when it believes the value of the company's stock will depreciate and covers (buys back) the shares when a target price has been reached.  The adviser's use of its proprietary models typically results in active trading and the adviser may engage in frequent buying and selling of portfolio securities to achieve the Portfolio's investment objectives. Although current income is not the Portfolio’s primary focus, it may invest in Underlying Funds that, in turn, invest in long, medium, or short-term bonds and other fixed income securities of varying credit quality, whenever the adviser believes they offer a potential for capital appreciation, for example high yield bond funds.  Typically, the Portfolio will not invest directly in bonds and other fixed income securities.  However, if warranted pursuant to the adviser’s proprietary investment models, the Portfolio may pursue such direct investments to the extent the adviser deems them consistent with the Portfolio’s investment objective.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Many factors affect the Portfolio's net asset value and performance. · Derivatives Risk:  The Portfolio may invest in Underlying Funds that use derivatives (including options, futures and options on futures) to invest or to hedge.  An Underlying Fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments.   · Equity Risk:  The net asset value of the Portfolio will fluctuate based on changes in the value of the equity securities held by the Portfolio or Underlying Funds that invest in U.S. and/or foreign equity securities.  Equity prices can fall rapidly in response to developments affecting a specific company or industry, or to changing economic, political or market conditions. · Fixed Income Risk:  The value of the Portfolio's investments in fixed income securities whether held directly or through Underlying Funds, will fluctuate with changes in interest rates.  Typically, a rise in interest rates causes a decline in the value of fixed income securities.  On the other hand, if rates fall, the value of the fixed income securities generally increases. Your investment will decline in value if the value of the Portfolio’s investments decreases. In addition, Underlying Funds may invest in high yield bonds sometimes referred to as “junk bonds.”  These bonds are speculative investments that carry greater risks and are more susceptible to real or perceived adverse economic and competitive industry conditions than higher quality fixed income securities. · Foreign Risk:  When the Portfolio invests in foreign securities directly or through ADRs or Underlying Funds, the Portfolio could be subject to greater risks because the Portfolio’s performance may depend on issues other than the performance of a particular U.S. company or U.S. market sector.  Foreign securities typically have less financial disclosure than U.S. securities and may expose the Portfolio to tax, currency exchange rate and repatriation risks. · Issuer-Specific Risks:  The price of an individual security can be more volatile than the market as a whole and can fluctuate differently than the market as a whole.  An individual issuer’s securities can rise or fall dramatically with little or no warning based upon such things as a better (or worse) than expected earnings report, news about the development of a promising product or service, or the loss of key management personnel. · Management Risk:  The adviser's dependence on technical and fundamental models and judgments about the attractiveness, value and potential appreciation of particular asset classes, securities and Underlying Funds in which the Portfolio invests may prove to be incorrect and may not produce the desired results.   · Portfolio Turnover Risk:  As to the portion of the portfolio invested in ETFs, closed-end investment companies, equities and fixed income securities, turnover may result in higher brokerage commissions, dealer mark-ups and other transaction costs.  The adviser's investment style will likely result in most capital gains within the portfolio being realized as short-term capital gains which will be subject to higher tax rates than long-term capital gains. · Short Position Risk:  The Portfolio will incur a loss as a result of a short position if the price of the short position instrument increases in value between the date of the short position sale and the date on which the Portfolio purchases an offsetting position.  Short positions may be considered speculative transactions and involve special risks, including greater reliance on the adviser’s ability to accurately anticipate the future value of a security or instrument.  The Portfolio's losses are potentially unlimited in a short position transaction. · Underlying Funds Risk:  Mutual funds, closed-end funds and ETFs are subject to investment advisory and other expenses, which will be indirectly paid by the Portfolio.  As a result, the cost of investing in the Portfolio will be higher than the cost of investing directly in other investment companies and may be higher than other mutual funds that invest directly in stocks and bonds.  The ETFs in which the Portfolio invests will not be able to replicate exactly the performance of the indices they track and the market value of ETF and closed-end fund shares may differ from their net asset value.  Each other investment company and ETF is subject to specific risks, depending on the nature of the fund.  falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
