Here is a reference list of the 50 largest healthcare service and hospital & clinic providers as of January 2017. This is an attractive sector as global populations age and have more money to spend on health care, and ROA rates tend to cluster around 7% in this moderately capital intensive but still skill and labor intensive industry. I’m of course interested in trends in better using technology and information to provide better and lower cost health care, which may lower costs while maintaining profit margins in health care.
