Investment Philosophy
Aperture’s investment philosophy is built on the core principle of 'Active Management with Accountability,' which seeks to align the incentives of the firm and its managers with those of its investors. The firm rejects the traditional asset-gathering model that relies on high fixed management fees, instead utilizing a performance-linked compensation structure where fees are primarily earned through outperformance relative to benchmarks. Aperture believes that capacity constraints are vital to maintaining a robust opportunity set and avoiding the pitfalls of 'closet indexing.' By combining fundamental research with a disciplined focus on downside protection and selective deployment, the firm aims to capture differentiated opportunities in credit and equity markets while maintaining a client-centric focus on alpha generation.
