One Firm, One Investment Philosophy?

We have heard both investment managers and evaluators of managers grappling with the question: How many investment philosophies should an investment firm have?

We believe a firm should be able to articulate a sound investment philosophy for every investment strategy it offers, regardless of whether that strategy is packaged as one product or several related products. An investment strategy is the application of a set of beliefs to a specific set of opportunities. A strategy is an approach for practicing a philosophy, including beliefs about internal skills, portfolio construction and risk management.

A firm with a narrow investment focus might well have only one investment philosophy. For multi-strategy firms, we think it’s perfectly acceptable for each investment strategy team within the firm to have its own investment philosophy.
