UnitedHealth Group (UNH -1.98%) reported mixed news on earnings last week. Revenue, at $31.7 billion (up about 5% year-over-year), slightly missed analyst estimates, while earnings per share, at $1.10, were down from $1.16 in first quarter 2013.

Management pulled no punches in broadly blaming the Affordable Care Act, also known as Obamacare, for the decline in earnings, with the company announcing that Obamacare and Medicare cuts from the sequester combined to shave $0.35 per share from earnings. There was also some interesting commentary on hepatitis C drugs and the impact of that expense on UNH's earnings.

Both of these are issues that may be generalizable to other insurers, and indeed investors scared by UnitedHealth Group's report sent most insurance stocks down on Friday.
