US 50 Dividend Strategy Portfolio Series 19

Under normal circumstances, the Trust invests at least 80% of the value of its assets in dividend-paying common stocks of U.S. companies.

The Sponsor, with the assistance of Guggenheim Partners Investment Management, LLC (“GPIM”), an affiliate of Guggenheim Partners, LLC, has selected the securities to be included in the Trust’s portfolio. The Sponsor and GPIM believe that companies that distribute significant dividends on a consistent basis generally demonstrate financial strength and positive performance relative to their peers.

The Trust’s portfolio was constructed and the securities were selected on January 16, 2019 (the “Security Selection Date”) using the following security selection rules:

1. Initial Universe: Begin with the universe of all stocks issued by large-, mid- and small-capitalization companies that trade on one of the three major U.S. exchanges and that are designated as a U.S. company by the Morningstar US Market Index as of the Security Selection Date. This may include U.S.-listed foreign securities and real estate investment Trusts.

2. Define Sub-Universe: Reduce the initial universe of securities to a sub-universe that meets the following requirements, as of the Security Selection Date:

• Exclude securities with a share price less than $5.

• Exclude securities with a market capitalization less than $1 billion, as provided by FactSet based on the closing price as of the Security Selection Date.

• Exclude securities with trading liquidity of less than $1 million, as determined by the median daily dollar trading volume (i.e., volume in shares multiplied by the closing price for the day, as provided by FactSet) during a 90-trading day look back from the Security Selection Date.

3. Rank on Dividends: Rank every company identified in the sub-universe against other companies in the same sectors/groups, as defined by Global Industry Classification Standard (“GICS”) (the Sponsor combines the financial and real estate sectors as one sector, as they were one sector prior to September 1, 2016) as of the Security Selection Date, based on current dividend yield. The dividend yields were calculated by annualizing the last quarterly or semi-annual ordinary dividend declared and dividing the result by the market value of the security as of the close of business on the Security Selection Date.

4. Selection: Select from the sub-universe the five securities within each of the 10 GICS sectors/groups (the Sponsor combines the financial and real estate sectors as one sector, as they were one sector prior to September 1, 2016) for this strategy with the highest dividend yield and equally weight these securities to create a portfolio of 50 equally-weighted common stocks as of the Security Selection Date, ensuring a minimum 80% in U.S. incorporated companies. If the portfolio violates the 80% minimum in U.S. incorporated companies, the lowest yielding foreign incorporated security will be removed and replaced by the next highest yielding U.S. incorporated company in that sector. This substitution process will be repeated, if necessary, until 80% of the portfolio consists of U.S. incorporated companies.

Please note that due to the fluctuating nature of security prices, the weighting of an individual security or sector in the Trust portfolio may change after the Security Selection Date.

As with all investments, you may lose some or all of your investment in the Trust. 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:

• Securities prices can be volatile. The value of your investment may fall over time. Market value fluctuates in response to various factors. These can include stock market movements, purchases or sales of securities by the Trust, government policies, litigation, and changes in interest rates, inflation, the financial condition of the securities’ issuer or even perceptions of the issuer. 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.

• Share prices or dividend rates on the securities in the Trust may decline during the life of the Trust. There is no guarantee that share prices of the securities in the Trust will not decline and that the issuers of the securities will declare dividends in the future and, if declared, whether they will remain at current levels or increase over time.

• Securities selected according to this strategy may not perform as intended. The Trust is exposed to additional risk due to its policy of investing in accordance with an investment strategy. Although the Trust’s investment strategy is designed to achieve the Trust’s investment objective, the strategy may not prove to be successful. The investment decisions may not produce the intended results and there is no guarantee that the investment objective will be achieved.

• The Trust includes real estate investment Trusts (“REITs”). REITs may concentrate their investments in specific geographic areas or in specific property types, such as, hotels, shopping malls, residential complexes and office buildings. The value of the REITs and other real estate securities and the ability of such securities to distribute income may be adversely affected by several factors, including: rising interest rates; changes in the global and local economic climate and real estate conditions; perceptions of prospective tenants of the safety, convenience and attractiveness of the properties; the ability of the owner to provide adequate management, maintenance and insurance; the cost of complying with the Americans with Disabilities Act; increased competition from new properties; the impact of present or future environmental legislation and compliance with environmental laws; changes in real estate taxes and other operating expenses; adverse changes in governmental rules and fiscal policies; adverse changes in zoning laws; declines in the value of real estate; the downturn in the subprime mortgage lending market and the real estate market in the United States; and other factors beyond the control of the issuer of the security.

• The Trust invests in U.S.-listed foreign securities. The Trust’s investment in U.S.-listed foreign securities presents additional risk. Securities of foreign issuers present risks beyond those of domestic securities. More specifically, 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.

• The Trust invests in securities issued by small-capitalization and mid-capitalization companies. These securities customarily involve more investment risk than securities of large-capitalization companies. Small-capitalization and mid-capitalization companies may have limited product lines, markets or financial resources and may be more vulnerable to adverse general market or economic developments.

• Inflation may lead to a decrease in the value of assets or income from investments.

• The Sponsor does not actively manage the portfolio. The Trust will generally hold, and may, when creating additional units, continue to buy, the same securities even though a security’s outlook, market value or yield may have changed.
