This morning's trading has marked a bad day for the market so far. The Nasdaq has decreased 0.4%; the S&P 500 has slipped 0.2%; and the Dow is trading down 0.2%. The healthcare sector is the category of stocks relating to medical and healthcare goods or services. This sector includes hospital management firms, health maintenance organizations (HMOs), biotechnology and a variety of medical products. Stocks in the healthcare sector are often considered to be defensive because the products and services are essential. Even during economic downturns, people will still require medical aid and medicine to overcome illness. Having a consistent demand for goods and services makes this sector less sensitive to business cycle fluctuations.

The Healthcare sector (XLV) is currently ahead of the overall market, down only 0.2%, and its biggest movers are currently:
