According to Yahoo Finance at this time, health insurance share prices are down between 1.5% and 6%, while hospital groups shares are rising between 3 and 7%.

For the hospital groups, thirty million new insured customers is just pure good news.
Stocks of major insurance companies fell sharply as analysts sorted through the ruling. UnitedHealth Group declined 3 percent, WellPoint almost 6 percent and AFLAC 1.5 percent.
Hospital chains rose. Hospital Corp. of America was up 7 percent. Quest Diagnostics, which runs laboratories, was up 2.5 percent.
