The Index is an unmanaged equal-weighted version of the S&P 500 Health Care Index that consists of the common stocks of industries, such as healthcare equipment and supplies, healthcare providers and services, and biotechnology and pharmaceuticals that comprise the healthcare sector of the S&P 500 Index.
