Vanguard Health Care Fund Admiral Shares 

For more than 25 years, this actively managed fund has offered investors low-cost exposure to domestic and foreign companies involved in various aspects of the health care industry, such as pharmaceutical firms, medical supply companies, and research firms. The fund tends to be more geographically diverse and exhibit lower turnover than other health care funds. Still, one risk to note is the fund’s narrow scope, investing solely within the health care sector. Returns may vary widely from year to year, so this fund should be considered complementary to a diversified portfolio with a long-term time horizon.
