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.
