US close: Health and big-tech send S&P 500 to second weekly drop

The Dow Jones Industrials lost 0.33% or 57.94 points to end the session at 17,675.16, alongside losses of 0.33% for the S&P 500 and of 0.92% in the tech-laden Nasdaq.

That saw the S&P 500 register its second consecutive retreat, with a weekly loss of 1.2%.

In Europe, the main indices were all over 1% higher as both sides of the referendum debate suspended campaigning until Saturday at the earliest following the murder of a British MP on Thursday.

Labour MP Jo Cox was shot and stabbed in her constituency town of Birstall near Leeds, allegedly by local resident Tommy Mair, who is reported to have shouted “Britain First” as he attacked her. There was a sense among market participants on Friday that the incident could sway public opinion back towards a Remain vote.

“One of the triggers for the change in market sentiment appears to be the suspension of Brexit campaigns following tragic killing of MP Jo Cox. The suspension of campaigns just means Brexit can temporarily move to the sidelines,” said Lawler.

“The killer is reported to have said ‘Britain First’ before shooting the MP, who was a strong believer in Britain remaining in the European Union. If true, it could tarnish the image of pro-Brexit supporters.”

Meanwhile, oil prices recovered, with West Texas Intermediate up $1.99 a barrel to $47.98 despite the latest weekly data from Baker Hughes revealing a third back-to-back rise in the US oil rig count, which was up by nine to 337.
