Stocks of several big carriers outpaced gains on the broader market Tuesday, as enrollment began for a key provision of PPACA.

Hailing it as an "historic day," President Barack Obama pressed forward his flagship health care program Tuesday, inaugurating new insurance exchanges to expand access for those without coverage despite the shutdown taking hold across much of the government.

Researchers say 80 percent of consumers will choose a health care plan on the exchanges that costs too much.

The partial government shutdown that began Tuesday left many federal workers uncertain of their financial future, with many facing unpaid furloughs or delays in paychecks.

Questioned about whether shutting down the government was a good strategy to block the PPACA, respondents decisively said "no."

President Barack Obama's long-anticipated launch Tuesday of new insurance exchanges to provide health care to millions of uninsured Americans is coming under the cloud of a government shutdown that began the same day.
