Boston Common’s US Large-Cap Value strategy invests in misvalued companies with catalysts for rerating. These firms have sound governance and a history of responsible financial management that we feel are capable of consistent, visible profitability over a long-time horizon and are trading at a discount to intrinsic value. The ESG team conducts bottom-up research on companies, analyzing material issues in each sector. Financial analysts use this data to identify companies with strong ESG characteristics and build a portfolio focus list. Through an ESG-enriched investing framework, active management, and engaged ownership, the strategy has delivered consistently strong risk-adjusted financial returns and positive social change.
