Bottom Line

Overall, health insurance and benefit providers have helped the fund early on in 2016, despite overall losses for the fund on the year. Pharmaceuticals in particular are continuing to be hit hard with scrutiny from U.S. government regulators over drug price increases that were considered unduly large. In addition, while health care stocks have been some of the best performing stocks during the current bull market, the health care sector is the worst performing U.S. sector with YTD losses of 9.40%, as of March 2016. With weakness currently holding most of the health care sector, the T. Rowe Price Health Sciences Fund will likely continue to follow suit and take a breather after years of strong returns.
