LME three-month copper rose above $14,000/t for the first time since June 3 as traders monitor rising US copper stocks and a potential US tariff decision by President Trump. IHS Markit shipping data show more than 200,000 tonnes of copper arrived at US ports in July—the largest monthly inflow since records began in 2014—adding to US warehouse and port stockpiles and tightening available supply for buyers elsewhere. A planned US refined-copper tariff remains uncertain; the Commerce Department was due to issue recommendations by June 30 but has not published a decision. US domestic copper prices trade above LME levels, leaving cross-market arbitrage opportunities.

Aug 4 — A-shares tied to co‑packaged optics (CPO) and compute hardware rallied sharply. Multiple names hit daily limits, including Yongding and Dongshan Precision; Tianfu Communication, Zhongji Xuchuang and Xinyisheng rose over 11%. The ChiNext index jumped more than 5% in the afternoon and a CPO-heavy communications ETF gained over 8%. NVIDIA senior VP Gilad Shainer said CPO has entered volume production and flagged vertical scale‑up as the largest future market opportunity for optical communications, with required bandwidth efficiency about ten times that of horizontal scale‑out. Separately, Phoenix cited Nikkei Asia reporting that AI-driven memory shortages have prompted HP, ASUS and Acer to start using small volumes of CXMT memory chips; the report pushed CXMT shares to reverse earlier losses and surge in the afternoon.
