Guggenheim Short Duration High Yield Trust Series 7

The Trust will invest in a portfolio of high yield corporate bonds. The Sponsor will select bonds that it believes have the best chance to meet the Trust’s investment objective over its life.

The portfolio of the Trust consists of high yield corporate debt obligations which may include corporate bonds, mortgage- and asset-backed securities, loan participations, pass through securities and corporate instruments. As of the initial date of deposit (the “Inception Date”), at least 80% of the bonds in the portfolio are rated below investment-grade as determined by at least one or more nationally recognized statistical rating organizations. High yield or “junk” bonds are frequently issued by corporations in the growth stage of their development or by established companies which are highly leveraged or whose operations or industries are depressed. Obligations rated below investment-grade should be considered speculative as these ratings indicate a quality of less than investment-grade. Because high yield bonds are generally subordinated obligations and are perceived by investors to be riskier than higher rated securities, their prices tend to fluctuate more than higher rated securities and are affected by short-term credit developments to a greater degree than investment-grade bonds. See “Description of Bond Ratings” in the prospectus for additional information.

“Duration” is the estimated number of years required to receive the present value of future payments, both of interest and principal, of a bond. Duration is often used as an indicator of a bond’s price volatility resulting from changes in interest rates. The Sponsor considers this Trust to be a “short duration” portfolio because the average weighted duration of the bonds in the Trust is 2.3 years. The duration of the bonds in the Trust range from 0.7 to 4.66 years.

The Trust intends to pay interest distributions each month and expects to prorate the interest distributed on an annual basis; see “Distributions” in the prospectus. The record dates and distribution dates for principal and interest distributions are the 15th and 25th of each month, respectively. Furthermore, investors may receive principal distributions from bonds being called or sold prior to their maturity or as bonds mature.

The Sponsor has selected Guggenheim Partners Investment Management, LLC ("GPIM"), a wholly-owned subsidiary of Guggenheim Partners, LLC, to assist the Sponsor with the selection of the Trust’s portfolio.

The Sponsor considered the following factors, among others, in selecting the bonds:

• The bonds may be rated below investment-grade by at least one or more nationally recognized statistical rating organizations;
• The price of the bonds relative to other bonds with comparable characteristics;
• The diversification of bonds with respect to the issuer with no one issuer comprising more than 20% of the final portfolio;
• Attractiveness of the interest payments relative to bonds with similar characteristics; and
• The potential for early return of principal or any event risk which could have a negative impact on the price of the bonds.

As with all investments, you may lose some or all of your investment in the Trust. Units of the Trust are not deposits of any bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. No assurance can be given that the Trust’s investment objective will be achieved. The Trust also might not perform as well as you expect. This can happen for reasons such as these:

• At least 80% of the bonds held by the Trust are rated below investment-grade and are considered to be “junk” securities. Below investment-grade obligations are considered to be speculative and are subject to greater market and credit risks, and accordingly, the risk of non-payment or default is higher than with investment-grade securities. In addition, below investment-grade bonds may be more sensitive to interest rate changes and more likely to receive early returns of principal.
• Corporate bonds are fixed rate debt obligations that generally decline in value with increases in interest rates. Foreign and U.S. interest rates may rise or fall by differing amounts and, as a result, the Trust’s investment in foreign securities may expose the Trust to additional risks. Generally, bonds with longer periods before maturity are more sensitive to interest rate changes.
• Corporate bonds are subject to credit risk in that an issuer of a bond may be unable to make interest and principal payments when due. In general, lower rated bonds carry greater credit risk.
• There is no assurance that the Trust portfolio will retain for any length of time its present size and diversity. As indicated in the “Trust Portfolio,” over 50% of the bonds in the Trust may be called prior to their stated maturity date and will remain callable throughout the life of the Trust. A call provision is more likely to be exercised by the issuer when the offering price valuation of a bond is higher than its call price. Such price valuation is likely to be higher in periods of declining interest rates. In such cases, the proceeds from such redemptions will be distributed to unit holders. The Estimated Current Return and Estimated Long-Term Return of the units may be adversely affected by such sales or redemptions. As stated below, the size and diversity of the Trust may also be affected by the Trust’s sale of bonds to meet redemptions, for credit issues and in other circumstances.
• The Sponsor does not actively manage the portfolio. Because the portfolio is fixed and not managed, in general, the Trust only sells bonds at the Trust’s termination or in order to meet redemptions, for tax purposes, for credit issues or to pay sales charges and expenses. As a result, the price at which a bond is sold may not be the highest price the Trust could have received during the life of the Trust.
• No assurance can be given that the Trust’s investment objective will be achieved. This objective is subject to the continuing ability of the respective issuers of the bonds to meet their obligations.
• The Trust is subject to market risk. Market value fluctuates in response to various factors. These can include changes in interest rates, inflation, the financial condition of a bond’s issuer, perceptions of the issuer, ratings on a bond, or political or economic events affecting the issuer.
• Due to the current state of the economy, the value of the securities held by the Trust may be subject to steep declines or increased volatility due to changes in performance or perception of the issuers. Starting in December 2007, economic activity declined across all sectors of the economy, and the United States experienced increased unemployment. The economic crisis affected the global economy with European and Asian markets also suffering historic losses. Extraordinary steps have been taken by the governments of several leading countries to combat the economic crisis; however, the impact of these measures is not yet fully known and cannot be predicted.
• An issuer or an insurer of the bonds may be unwilling or unable to make principal payments and/or interest payments in the future, may call a security before its stated maturity or may reduce the level of payments made. In addition, there is no guarantee that the issuers will be able to satisfy their interest or principal payment obligations to the Trust over the life of the Trust. This may result in a reduction in the value of your units.
• The Trust includes restricted bonds. Restricted bonds are issued under Rule 144A of the Securities Act of 1933, as amended, and may only be resold in privately negotiated transactions pursuant to federal securities laws or in a public offering with respect to which a registration statement is in effect under the Securities Act.
• The financial condition of an issuer or an insurer of the bonds may worsen or its credit ratings may drop, resulting in a reduction in the value of your units. This may occur at any point in time, including during the primary offering period.
• The income generated by the Trust may be reduced over time in response to bond sales, changes in distributions paid by issuers, unit redemptions and expenses.
• The Trust will invest in foreign securities. The Trust’s investment in foreign securities presents additional risk. Foreign risk is the risk that foreign securities will be more volatile than U.S. securities due to such factors as adverse economic, currency, political, social or regulatory developments in a country, including government seizure of assets, excessive taxation, limitations on the use or transfer of assets, the lack of liquidity or regulatory controls with respect to certain industries or differing legal and/or accounting standards.
• Certain bonds in the Trust may have been purchased by the Sponsor on a “when issued” basis. Bonds purchased on a “when issued” basis have not yet been issued by the issuer on the Inception Date (although such issuer has committed to issue such bonds). The effect of the Trust holding a “when issued” bond is that unitholders who purchase the their units prior to the delivery date of such bond may have to make a downward adjustment in the tax basis of their units. Such downward adjustment may be necessary to account for interest accruing on such “when issued” bond during the time between their purchase of units and delivery of such bonds to the Trust.
• The Trust may sell bonds to meet redemptions, to pay deferred sales fees and expenses, for credit issues and in other circumstances. Accordingly, the size, diversity, composition, returns and income generated by the Trust may be adversely affected. In addition, such sales of bonds may be at a loss. If such sales are substantial enough, provisions of the Trust’s indenture could cause a complete and unexpected liquidation of the Trust before its scheduled maturity, resulting in unanticipated losses for investors.
• Certain of the bonds included in the Trust may be original issue discount bonds or “zero coupon” bonds, as noted in “Trust Portfolio.” These bonds may be subject to greater price fluctuations with changing interest rates and contain additional risks.
• Inflation may lead to a decrease in the value of assets or income from investments.
