The health-care sector is hot—but it's not due just to the wild ride in booming biotech.
The health-care sector as a whole has been a standout in the S&P 500, up 9 percent year-to-date through the end of May and the top sector gainer last month, with a 4 percent return. That's compared to the S&P 500's meager 2.3 percent for the year and 1 percent in May.
No health-care niche can keep pace with biotech—it just notched its best month since August with a 9.3 percent return in May. But solid returns are being generated across the broader universe of health-care stocks. Older, more established medical technology companies are a good example of a health-care bet that couples global growth with dividends.
