To invest at least 80% of net assets in common stocks of companies engaged in the research, development, production, or distribution of products or services related to health care, medicine, or the life sciences. The fund defines the health sciences industry broadly and divides it into four main areas: pharmaceutical companies; health care services companies; medical products and devices providers; and biotechnology firms. While the fund can invest in companies of any size, the majority of fund assets are expected to be invested in large- and mid-capitalization companies.

All investments are subject to market risk, including possible loss of principal. Due to the fund's concentration in health sciences companies, its share price will be more volatile than that of more diversified funds. Further, these firms are often dependent on government funding and regulation and are vulnerable to product liability lawsuits and competition from low-cost generic products.
**This chart displays relative risk of each U.S. mutual fund listed using standard deviation of returns. Those values are provided in the bars at the top of the chart.
Methodology: We evaluate the standard deviation and its resulting placement within a specific risk/return category on an annual basis. A fund is generally placed in a risk/return category based on the 10-year standard deviation of its performance.
If a fund is less than 10 years old, the actual fund performance history is supplemented with the primary prospectus benchmark history to obtain a full 10-year history, or longest time period available up to 10 years.
For an Asset Allocation fund with less than 10 years of performance history, sub-strategy returns are used.
When a sub-strategy is less than 10 years old, the actual sub-strategy performance history is supplemented with benchmark history to obtain a full 10-year history, or longest time period available up to 10 years.
Risk return categories overlap; a fund with a standard deviation in the overlap between two categories, denoted by a plus (+), is placed so that its risk categorization is better aligned with anticipated return characteristics an investor may experience going forward at the discretion of T Rowe Price.
When a fund has a cash-like benchmark, denoted by a double plus (++), its standard deviation is estimated using only available fund returns. If the fund is less than 10 years old, benchmark returns are not used to obtain a full 10-year history because they would artificially suppress the volatility estimate.
All investments are subject to market risk, including the possible loss of principal. Standard deviation of returns, a measure of price volatility, is one measure of risk. Please consult the funds' prospectuses for a more complete discussion of the funds' risks.
