The Dow and S&P 500 posted a fifth consecutive session of gains, booking their longest winning streak of 2025 to date and settling well off their session lows in a muted trading to open a very busy week of corporate earnings and economic data - Dow rose +114-points or +0.28%. Boeing Co rose +2.44% to US$182.30, buoyed by an upgrade from analysts at Bernstein to ‘outperform with a target price of US$218 (from US$181 previously), and as its deal to reacquire Spirit AeroSystems Holdings (+2.61%) cleared another hurdle. International Business Machines (IBM) Corp +1.61% after pledging a US$150B investment over the next five years to aid the development of technology in the U.S. The company said it would invest more than US$30B in research and development to continue its domestic manufacturing of mainframe and quantum computers. Nvidia Corp fell -2.05% following a Wall Street Journal (WSJ) report that China's Huawei Technologies has developed a new chip called the Ascend 910D, with hopes it will become be more powerful than Nvidia’s H100. Huawei is already poised to ship more than 800,000 of its Ascend 910B and 910C chips to customers including state-owned telecommunications carriers and private AI developers, such as TikTok’s parent ByteDance, according to the WSJ. Nvidia’s H100 was released in 2022 and has since been superseded by later generations of its Hopper chips and its new Blackwell AI semiconductors. Nvidia is prohibited from selling its most powerful AI chips to Chinese companies.
