NAPERVILLE, Ill, Sept. 5, 2013 /PRNewswire/ -- Calamos Investments ®* announces that its flagship Calamos Convertible Fund (A Shares: CCVIX; C Shares: CCVCX; I Shares: CICVX) is reopened to new accounts and new investments as of September 6, 2013. "We're pleased to reopen our convertible mutual fund to new investors at what we consider to be an opportune time to invest in these unique hybrid securities," said John P. Calamos, Sr., Chief Executive Officer and Global Co-Chief Investment Officer of Calamos Investments. "An improving global economy and widening spreads have boosted interest in the asset class by issuers, resulting in an improving and diversified convertible market that we expect will become more robust. Moreover, during periods of rising rates and economic expansion, convertibles have historically outperformed their more traditional fixed-income counterparts." Calamos has been a pioneer and long-time champion of the convertible asset class, launching the fund in 1985 as one of the first convertible mutual funds.
