C000017621 Investment Objective and Strategy
Calamos Growth and Income Portfolio describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Calamos Advisors Trust/IL.
Investment objective
Calamos Growth and Income Portfolio's investment objective is high long-term total return through growth and current income.
Principal investment strategy
"The Portfolio invests primarily in a diversified portfolio of convertible instruments (including synthetic convertible instruments) and equity and fixed-income securities of U.S. companies without regard to market capitalization. In pursuing its investment objective, the Portfolio attempts to utilize these different types of securities to strike, in the investment adviser's opinion, the appropriate balance between risk and reward in terms of growth and income. A synthetic convertible instrument is designed to simulate the economic characteristics of a convertible security through the combined features of a debt instrument, or loan, and a security providing an option on an equity security. The Portfolio may establish a synthetic convertible instrument by combining a fixed-income security with the right to acquire an equity security.
The fixed-income and equity option components may have different issuers, and either component may change at any time. The Portfolio may invest up to 25% of its net assets in foreign equity securities. Foreign securities are securities issued by issuers that are organized under the laws of a foreign country or that have a substantial portion of their operations or assets in a foreign country or countries, or that derive a substantial portion of their revenue or profits from businesses, investments or sales outside of the United States. The Portfolio may also invest in foreign securities that are represented in the United States securities markets by American Depositary Receipts (""ADRs"") or similar depositary arrangements. The Portfolio's foreign debt investments can be denominated in U.S.
dollars or in foreign currencies. Debt securities issued by a foreign government may not be supported by the ""full faith and credit"" of that government. The Portfolio attempts to keep a consistent balance between risk and reward over the course of different market cycles, through various combinations of stocks, bonds and/or convertible securities, to achieve what the Portfolio's investment adviser believes to be an appropriate blend for the then-current market. As the market environment changes, portfolio securities may change in an attempt to achieve a relatively consistent risk level over time. At some points in a market cycle, one type of security may make up a substantial portion of the portfolio, while at other times certain securities may have minimal or no representation, depending on market conditions.
Interest rate changes normally have a greater effect on prices of longer-term bonds than shorter-term bonds. The Portfolio's investment adviser seeks to lower the risks of investing in stocks by using a ""top-down approach"" of diversification by company, industry, sector, country and currency and focusing on macro-level investment themes. Consistent with the Portfolio's investment objective and principal investment strategies, the Portfolio's investment adviser views the strategies as low volatility equity strategies and attempts to achieve equity-like returns with lower than equity market risk by managing a portfolio that it believes will exhibit less volatility over full market cycles."
