Quality is Durability
02:11
Our high-quality investment approach focuses on durability — a company’s ability to sustain its business model and generate enduring growth.

Our focus on durability is important, as it allows our businesses to participate in up markets. But just as important, it provides the ability to protect capital in more difficult environments.

Focusing on both offensive and defensive quality helps our analysts identify durable businesses in the pursuit of better portfolio outcomes.

Our quality philosophy is unique because it is multipronged. We look at quality from a growth lens, not only being able to protect the core today, but also being able to reinvest, reinvent, and then grow for the long term.

Portfolio Manager, Global Research Analyst, Global Equity Team

Diversifying Across the Corporate Lifecycle
02:20
Companies at different stages of the corporate lifecycle exhibit different risk and return characteristics, providing an opportunity to further diversify a portfolio.

Many investors diversify a portfolio based on market cap or where a company is domiciled. As part of our quality analysis, we also focus on where companies are in their corporate cycle to further diversify a portfolio by growth stages.
