The portfolio generally commits at least 80% of its assets to securities issued by companies fundamentally engaged in the ownership or management of healthcare providers like hospitals, nursing homes, and health maintenance organizations, along with other businesses delivering health care services. Its primary investments are in common stocks, sourced from both domestic and international issuers. To select investments, the fund employs fundamental analysis, evaluating aspects such as an issuer's financial strength, its competitive position in the industry, and broader market and economic conditions. This is a non-diversified fund.
