Calamos Dynamic Convertible And Income Fund (CCD) is a closed-end fund which "can invest in convertibles and other fixed income securities with the aim of generating a high level of total return through a combination of capital appreciation and income. To help generate income and attempt to achieve a more favorable reward/risk profile, the fund's investment team also has the flexibility to sell options." (CCD site)
We covered a similar convertible bond-based CEF from Calamos in one of our recent articles: The Calamos Convertible and High Income Fund, CHY.
