US equity markets retreated after a volatile session as the drawn out debt ceiling negotiations continued to weigh on sentiment, with losses accelerating in afternoon trading - Dow fell -231-points or -0.69%, The broader S&P500 -1.12%, with Materials (down -1.54%) and Information Technology (-1.50%) falling ~1.5% to lead ten of the eleven primary sectors lower. Energy (up +1.04%) was the sole primary sector to advance overnight. The Nasdaq -1.26%. Apple Inc lost -1.52% after announcing a multibillion-dollar chip production deal with Broadcom Inc (up +1.20%). Apple said the partnership, which centres on 5G radio frequency components and builds on its existing relationship with Broadcom, was part of its 2021 commitment to spend US$430B with US suppliers and manufacturers over five years. The small capitalisation Russell 2000 lost -0.43%. The American Depository Receipts (ADRs) of Alibaba Group Holdings Ltd fell -3.74% after a strong session a day earlier, with reports that the company’s cloud and artificial intelligence (AI) arm has begun cutting 7% of staff (source: Barron’s). The move is a bid to optimise business operations on strategic areas - like AI - in the midst of a historic restructuring, and not representative of a wider downsizing, a person familiar with the matter and cited in the report said. Alibaba announced earlier this year the biggest restructuring in its history, a bid to unlock value by splitting into six units and to foster market competitiveness, a nod to regulators who have hammered the Chinese tech sector since late 2020.
