GLOBAL CONVERTIBLE FUND (CAGCX)

Choose a class

Overview

The fund invests in global convertible securities, striving to balance risk and reward while providing growth and income.

Key Features

  • Provides broadly diversified exposure to the global convertible bond universe
  • Leverages more than 40 years of research in convertible security investing
  • Seeks to provide upside participation in equity markets with less exposure to downside than an equity-only portfolio over a full market cycle
  • Blends global investment themes and fundamental research via active management

Portfolio Fit

Consisting of convertible securities that participate in upside equity movements with limited downside exposure, the fund can provide a means to manage risk vis-a-vis an equity allocation. The fund can also serve a role within a fixed-income allocation, as convertibles have performed well during periods of rising interest rates and inflation.

Calamos Convertible Experience Applied Globally

On December 31, 2014, Calamos launched the Calamos Global Convertible Fund, which applies more than 40 years of convertible investing experience to a global universe. We have invested in non-U.S. convertible securities since the late 1980s and have managed pure global convertible portfolios for our institutional clients since 2001. We are pleased to bring our institutional strength experience to bear on this new mutual fund.

The fund is actively managed—allying global topdown views with bottom-up analysis—with the intent to select the convertible securities of companies we believe offer the greatest investment value and growth potential in the world.

Bringing an Experienced Approach to Global Opportunity

Our new Global Convertible Fund leverages more than two decades of growth investing experience on the international stage.

Important Fund Information

  • Calamos Growth, Growth and Income, Opportunistic Value, Global Growth and Income, International Growth, Global Equity and Evolving World Growth Funds may invest in small and mid-size company securities, which generally present greater risk and higher volatility than investments in larger, more established companies.
  • Calamos Growth, Growth and Income, Opportunistic Value, Focus Growth, Global Growth and Income, International Growth, Global Equity and Evolving World Growth Funds invest a substantial portion of their assets in equity securities, which are subject to greater fluctuations in market value than other asset classes as a result of such factors as a company's business performance, investor perceptions, stock market trends, and general economic conditions.
  • Calamos Global Growth and Income, International Growth, Global Equity and Evolving World Growth Funds may invest up to 100% of assets in foreign securities. Total Return Bond Fund may invest up to 35% and all other Calamos funds up to 25% of assets in foreign securities. Investing outside the U.S. offers both risks and rewards. Increased volatility, changes in the value of foreign currencies, and difficulty in obtaining information are some of the risks involved.
  • Global Growth and Income, International Growth, Global Equity, Evolving World Growth and Total Return Bond Funds may invest in securities issued by companies in emerging markets; these may present additional risk due to the potential for greater economic and political instability in less developed countries.
  • Calamos High Income Fund invests and Total Return Bond Funds may invest in lower-rated fixed-income securities, often referred to as "junk bonds," which generally present greater risks than higher-quality securities, because of the greater likelihood that the company issuing the lower-rated securities will default on income and principal payments.
  • Calamos Growth and Income, Convertible and Market Neutral Income Funds: There are certain risks associated with an investment in a convertible bond such as a default risk—the company issuing a convertible security may be unable to repay principal and interest—and interest rate risk—the convertible may decrease in value if interest rates increase.
  • Calamos Market Neutral Income Fund engages in short sales. Short sales involve the risk that the Fund may incur a loss if the market value of a borrowed security increases between the date of the short sale and the date the Fund replaces the security. A short position in a security poses more risk than holding the same security long. Because a short position loses value as the security's price increases, the loss on a short sale is theoretically unlimited. It is possible that the market value of the securities the Fund holds in long positions will decline at the same time that the market value of the securities the Fund has sold short increases, thereby increasing the Fund's potential volatility. The Market Neutral Income Fund engages in short sales of convertible securities' underlying stock, which may increase volatility and portfolio turnover.
  • Calamos Total Return Bond Fund may invest in derivative securities, including options, futures contracts and swap agreements. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. There is no assurance that any derivative strategy used by the Fund will succeed.
  • In addition to market risk, there are certain risks associated with an investment in Calamos Total Return Bond Fund, such as default risk, the risk that the company issuing debt securities will be unable to repay principal and interest, and interest rate risk that the security may decrease in value if interest rates increase.
