U.S. equity index futures fell to a six-week low on Sunday in a sign Wall Street would start
the week defensively after Republicans pulled legislation to overhaul the U.S. healthcare system in a stunning setback for President Donald Trump.
S&P 500 e-mini futures ESv1 were down over 0.65 percent, shortly after electronic trading resumed on Sunday evening.
Volume of more than 17,000 contracts in the first 30 minutes marked the heaviest trading activity to kick off a week since Trump took office. That was roughly 2-1/2 times the average of fewer than 7,000 contracts in early Sunday evening trading since the inauguration.
U.S. Treasury futures were up 0.18 percent Sunday, indicating that yields would start the week lower when bonds start trading in Asia later.
Markets were unnerved last week by Trump’s inability to get enough support for legislation to reform the U.S. healthcare system, a major 2016 election campaign promise of the president and his allies.
