Management

Managed by Robeco Institutional Asset Management US Inc. (Since 12/1/2019)

Robeco is an international asset manager offering an extensive range of active investments, from equities to bonds. Research lies at the heart of everything they do, with a ‘pioneering but cautious’ approach that has been in their DNA since the foundation in Rotterdam in 1929. Robeco has invested in emerging markets since the early beginnings of the company and has a fully-dedicated emerging markets team in place since 1994. Based on award-winning academic research and experienced investment teams, quantitative investing is one of the key strengths of Robeco. In addition to the existing factor-based quantitative stock selection strategies in global and emerging markets, Robeco in 2006 introduced Conservative Equities: their active approach to low volatility investing. It is based on the anomaly that low-risk stocks tend to deliver a higher risk-adjusted return than high-risk stocks, contrary to classical finance theories. An approach that tends to lead to a portfolio that offers stable equity returns and high income.
