Calamos Investments
Calamos Investments is a diversified global investment management firm headquartered in Naperville, Illinois, offering a broad range of equity, fixed income, convertible securities, liquid alternatives, and multi-asset investment strategies to institutional and individual investors worldwide. Founded in 1977 by John P. Calamos, Sr., the firm built its reputation as a pioneer in convertible securities investing — a hybrid asset class combining features of both bonds and equities — before expanding into a comprehensive multi-asset investment platform serving clients across the full spectrum of investment needs. According to its website at calamos.com, the firm manages assets across traditional and alternative strategies for a global client base that includes pension funds, endowments, foundations, financial advisors, and individual investors seeking actively managed investment solutions.
Calamos' investment capabilities, described at calamos.com, encompass global equities and equity long/short strategies, investment-grade and high yield fixed income, convertible securities including both dedicated convertible and balanced convertible strategies, liquid alternative investments with low market correlation, and structured protection strategies including its innovative defined outcome ETF products that offer market participation with specific return buffers and floors. The firm's research-driven investment process draws on decades of analytical expertise in convertible securities — which provide valuable insights into both equity and credit markets — and applies rigorous fundamental analysis across all strategy types to identify investment opportunities that offer compelling risk-adjusted returns. Calamos operates from its headquarters in Naperville with additional offices in Chicago, New York, London, and other global financial centers.
Calamos has partnered with Aksia, a leading alternative investment adviser, to develop and offer credit and alternative investment strategies that complement Calamos' core convertible and equity capabilities. According to calamos.com, this partnership reflects the firm's commitment to expanding its alternatives platform and providing clients with access to a broader range of investment strategies across the liquid and illiquid alternatives spectrum. Calamos' combination of its decades-long convertible securities heritage, expanded multi-asset platform, innovative structured protection products, and alternative investment capabilities positions it as a differentiated investment manager with distinctive competencies across the hybrid securities market and a growing presence in the broader liquid and illiquid alternatives landscape.
