Here are the key evening market developments investors need to know.
NDRC Advances 'Six Networks' Infrastructure Plan
On August 19, the National Development and Reform Commission (NDRC) held a coordination meeting for major projects under the "Six Networks" initiative. Deputy Director Yue Xiuhu chaired the session, focusing on establishing a joint coordination mechanism for computing networks, new power grids, and next-generation communication networks. This "2+3+N" framework involves two power grid operators, three telecom carriers, and multiple computing-related enterprises, aiming to accelerate major project construction through collaborative efforts.
The "Six Networks" specifically encompass water networks, new power grids, computing networks, next-generation communication networks, urban underground pipeline networks, and logistics networks. China Galaxy Securities believes these networks, as critical infrastructure supporting technological strategy implementation, are poised for accelerated development. Computing networks, next-generation communication networks, and new power grids are particularly closely tied to the tech sector. With computing networks now entering the implementation phase, the technology industry is set to embrace three substantial opportunities in technical breakthroughs, scenario integration, and ecosystem collaboration, with leading enterprises poised to capture significant market expansion.
Moderna's Personalized Cancer Vaccine Achieves Historic Milestone
US pharmaceutical stocks surged on August 19 following a landmark development. Moderna shares skyrocketed, at one point gaining over 150%, while BioNTech SE advanced more than 17%. Merck climbed over 10%, reaching an all-time high, and Eli Lilly rose 5.3% to a record close, pushing its market capitalization to $1.21 trillion—the first pharmaceutical company in history to reach a $1.2 trillion valuation. As of 22:05 Beijing time, Moderna was still up 120%, lifting the entire sector. The Nasdaq Biotechnology Index jumped 5%, its largest intraday gain since April 2025, with Merck adding 11.3%.
The catalyst was the success of the personalized mRNA cancer vaccine co-developed by Moderna and Merck in a large Phase 3 clinical trial. This marks the first personalized cancer vaccine to demonstrate efficacy in a Phase 3 study, widely regarded as a milestone breakthrough in tumor immunotherapy.
SK Hynix Announces 40 Trillion Won Buyback
SK Hynix shares spiked as much as 5% in US trading on August 19 following the company's announcement of a plan to repurchase and cancel inventory shares worth 40 trillion won. The company also committed to returning at least 50% of free cash flow generated between 2025 and 2027 to shareholders. SK Hynix indicated it would continue pursuing additional buybacks and cancellations, with further shareholder return details expected alongside third-quarter earnings.
Analysts note that as memory chip price increases begin to moderate, the logic of relying solely on earnings growth to drive valuations faces challenges. Share buybacks and cancellations directly reduce floating share count, boosting earnings per share and net assets. Combined with substantial cash returns lowering holding costs, this strategy helps establish a price floor during the transitional period as investors digest peak growth expectations.
Northern Rare Earth's H1 Report Shows Super Investor Exit
Northern Rare Earth disclosed its semi-annual report on August 19, showing operating revenue of 25.799 billion yuan for the first half of 2026, up 36.75% year-on-year. Net profit attributable to shareholders reached 2.053 billion yuan, a surge of 120.46%, with basic earnings per share of 0.5679 yuan.
Notably, the top ten shareholders list as of June 30, 2026 no longer includes famed retail investor Zhang Jianping. According to the company's first-quarter report, Zhang held 72.2544 million shares as of March 31, 2026, ranking as the fourth-largest shareholder.
Broad-Based ETFs See Record Volume Again
Multiple broad-based ETFs saw significant volume expansion in late trading on August 19. By market close, ChinaAMC STAR 50 ETF and E Fund ChiNext ETF both exceeded 10 billion yuan in turnover, reaching 10.889 billion and 10.611 billion yuan respectively. ChinaAMC STAR Semiconductor ETF and Huatai-PineBridge CSI 300 ETF followed with 9.965 billion and 7.147 billion yuan. These four ETFs combined for 38.5 billion yuan in turnover, marking the second time in under a month that broad-based ETFs have seen such concentrated volume.
Institutional observers view the late-session volume surge in these "mega" ETFs as reflecting market confidence in the outlook. Beyond broad-based funds, sector-specific ETFs tracking semiconductor and semiconductor equipment themes also saw active trading. Seasoned market analysts suggest that while short-term volatility risks in the semiconductor sector are indeed increasing, the massive volume itself signals extremely high market attention.

China Responds to US AI Alliance Pressure
At a regular press briefing on August 19, Foreign Ministry Spokesperson Lin Jian responded to reports that the US government plans to write to signatories of the Joint Statement on AI Opportunity Partnerships, demanding they not simultaneously join US initiatives and other conflicting mechanisms.
Lin stated that artificial intelligence represents the collective wisdom and precious asset of all humanity. The international community widely anticipates extensive AI cooperation, and every country has the right to choose partners based on its own conditions and development needs. China firmly opposes forcing countries to choose sides or engage in bloc confrontation on AI issues. He urged all parties to abandon zero-sum thinking, uphold mutual benefit, respect nations' digital sovereignty, and work together to build a fair and reasonable global AI governance system that makes AI a driving force for shared prosperity and common security.

Toll and service fee standards for vessels will be set by the General Staff, with hostile, spy, or national security-threatening vessels prohibited from entering. If Iran's interests are harmed anywhere in the world, it will counter hostile countries and governments through measures including tariff increases or asset seizures at the strait.
China Determines EU Practices Constitute Improper Extraterritorial Jurisdiction

According to Articles 3 and 6 of China's Regulations on Countering Improper Extraterritorial Application of Foreign Laws, the Ministry of Justice, in conjunction with the Ministry of Commerce and other departments, investigated and determined that the EU's cross-border investigation practices against Chinese entities under its Foreign Subsidies Regulation in the investigation of JD.com constitute improper extraterritorial jurisdiction measures.
