Monitoring factor exposure
Robeco examines existing investment portfolios' exposure to factor premiums using its own customized scanning system. This is known as the 'Robeco Factor Exposure Monitor'.
The scan shows the relative underweights or overweights per factor (relative to the market portfolio). This can form a first step in the decision-making process for implementing factor investing.
