Calamos Global Dynamic Income Fund (CHW) is a closed-end fund that seeks a high level of current income with a secondary objective of capital appreciation through dynamic allocation among equities, convertible bonds, fixed-income securities, and alternative investments across global markets. The fund invests primarily in a diversified portfolio of convertible securities, common and preferred stocks, investment-grade and high-yield debt instruments, growth stocks of companies across all market capitalizations, higher-yield corporate and government bonds, and alternative strategies including arbitrage and call writes; it maintains at least 40% and up to 100% of managed assets in foreign securities, encompassing emerging markets. Launched by Calamos Investments LLC and managed by Calamos Advisors LLC, with an inception date of June 27, 2007, the fund is headquartered at 2020 Calamos Court, Naperville, Illinois 60563-2787, United States, and trades on the NASDAQ exchange. It employs leverage, with total managed assets of approximately $788 million, a leverage ratio of 30.52%, and an expense ratio of 2.62% based on managed assets, targeting investors seeking enhanced income and risk management relative to traditional fixed-income funds amid market volatility. In December 2024, the Board of Trustees approved a transition from a managed distribution policy to a level distribution policy for select Calamos closed-end funds including CHW alongside CCD, CHY, and CHI, aiming for more sustainable monthly payouts of $0.0500 per share; the fund continues regular monthly distributions funded by short-term capital gains, net investment income, and return of capital as needed, with recent characterizations showing primarily capital gains support.
