Pharmaceutical companies will keep hiking the prices for popular treatments and fighting off cheaper competitors.

Insurers are benefiting from the rising popularity of private Medicare Advantage plans.

UnitedHealth, the largest health insurance company by revenue, just forecasted a very profitable 2020, in line with Wall Street's estimates.
