The fund specifically represents the healthcare space within developed markets. It includes companies engaged in medical distributions, hospital/nursing management and services, pharmaceuticals, biotech, drugstore chains, and other medical specialties. Eligible securities are ranked by market-cap, and the top 135 securities are selected for inclusion with considerations to succeeding ranks until the portfolio reaches 150 constituents. Holdings are market-cap-weighted and are rebalanced on a quarterly basis. The fund may include firms of all sizes, however, its market-cap-focused strategy skews the fund towards large-caps.
