US stocks dip as Republicans unveil health plan

New York - US stocks dipped early on Tuesday as congressional Republicans unveiled a controversial health bill that traders worry could delay enactment of tax cuts and other growth measures.

The American Health Care Act would dismantle several core aspects of former president Barack Obama's health law, fulfilling a campaign pledge by President Donald Trump, but also potentially disrupting momentum for tax cuts.

Optimism about Trump's planned tax cuts and stimulus spending were a catalyst in a series of stock market records since the November election.

About 15 minutes into trading, the Dow Jones Industrial Average was at 20 917.67, down 0.2%.

In recent days, more analysts have begun to discuss a longer time horizon to implement key aspects of Trump's agenda. Barclays cited the health policy debate, as well as probes into Trump's relationship with Russia, as a reason to revise its forecasts for 2017 and 2018.

"The administration continues to spend time and political capital in ways we did not anticipate," Barclays said in the note last week.
