Port Capital Management

Paul Dietrich serves as Chief Executive Officer and chief investment decision-maker for the firm. He designed the core earnings-acceleration screening methodology and remains the named portfolio manager for the firm's large-cap growth strategies. Dietrich's tenure traces to the firm's founding, creating strong alignment between the investment process and the leadership that oversees it.

ESG integration functions as a fundamental screen rather than an exclusionary filter or a separate overlay. Companies that score poorly on governance indicators or exhibit high exposure to carbon-intensive fuel industries are removed from consideration before the upside-capture model screens for earnings acceleration. The resulting portfolio is designed to match or exceed the Russell 1000 Growth benchmark's growth profile while maintaining significantly lower ESG risk scores.

Unlike passive ESG indices that rely on third-party exclusionary criteria and market-cap weighting, Port Capital actively selects companies based on an earnings-acceleration model with a built-in governance and environmental screen. The active share is high, and the strategy has historically generated performance distinct from both traditional large-cap growth benchmarks and ESG index products. The approach treats ESG variables as forward-looking fundamental factors rather than backward-looking scoring artifacts.
