Sharemarket investors are looking for greater direction in an uncertain environment. The New Zealand sharemarket edged lower in mixed trading as investors sat on their hands amid uncertainty around Brexit, the rollout of any Covid-19 vaccine, and a stimulus package in the United States. The benchmark NZX 50 index slid 0.23 per cent, or 29.03 points, to 12,860.37 on Thursday, after closing at a record 12,889.40 on Wednesday. The UK and the EU have agreed to a Sunday deadline for a deal on Brexit, or there will be no deal, with “very large gaps” said to remain. Meanwhile in the US, Congress is still divided over the size and scope of any new stimulus package.
