One of the issues that favored the Democrats in controlling the House over the next two years was healthcare and the "pre-existing conditions" debate. This factor caused the spike in share prices for four healthcare insurers to new all-time highs as both sides of the aisle just may be willing to negotiate a reboot of Obamacare.

Medicaid expansion is set to grow by 500,000 after voters in three red states elected Democratic governors. Obamacare supporters cite victories that reprimanded Republicans for the failure to repeal and replace the Affordable Care Act. It remains to be seen whether healthcare can become an issue that brings Democrats and Republicans to the bipartisan table.

Each of the four health insurers charted below reported their quarterly earnings between Oct. 16 and Nov. 7 and kept alive winning streaks of eight to 20 quarters.
