Strategy Objective
To deliver absolute returns largely uncorrelated to equity and fixed income markets.
Key Differentiators
- Calamos is a pioneer in convertible and options investing, where analysis of public acquisitions and opportunities to alter risk reward through structure is an ingrained part of the investment process
- Our merger strategy is a natural extension of our experience managing hedged equity and convertible arbitrage strategies for more than 20 years on average as a team
- Because of this, we believe one of our main edges resides in public acquisitions where there are convertible bonds, liquid options or other securities within a target company's capital structure that allow us to alter risk reward through trade structure
