MINIMAX-W (00100) attracted a net buy of HK$2.696 billion. The Stock Connect list was adjusted, adding several targets including MiniMax, effective from August 6. A recent in-depth report by China Merchants Securities shows that MiniMax's ARR surged from approximately $100 million in December 2025 to around $430 million in April 2026. Token consumption increased by 152% from February to June, accelerating the validation of the conversion path from model capability to commercial revenue. Management is confident in achieving at least $1 billion in ARR by the end of 2026.
Kingboard Laminates (01888) saw a net buy of HK$753 million. Citigroup, citing SCI99 data, noted that in August, average prices for the three major electronic fabric series (1080, 2116, and 7628) rose 17%-18% month-on-month, reaching 13.1 yuan, 12.7 yuan, and 10.1 yuan per meter respectively, with cumulative year-to-date increases of 118%-165%. Citigroup pointed out that costs are accelerating their transmission to the CCL (Copper Clad Laminate) stage, opening a new round of price hikes.
Yangtze Optical Fibre and Cable (06869) received a net buy of HK$593 million. Kaiyuan Securities released a research report stating that capital expenditure by overseas giants is rising, with the commercial deployment of optical communications being validated simultaneously. The rapid expansion of cloud revenue indirectly confirms the acceleration of commercial deployment and the push for application-side implementation. The optical fiber leader's performance exceeded expectations, and demand certainty remains evident. The brokerage believes that the fiber demand driven by AI infrastructure construction is substantial, with clear demand certainty, and fiber leaders holding core positions in both domestic and international markets stand to benefit continuously.
Hua Hong Semiconductor (01347) and SMIC (00981) faced net sells of HK$185 million and HK$1.076 billion, respectively. BOC International ranked the sector as TSMC > Hua Hong > SMIC, citing Hua Hong's higher exposure to AI power analog, a better profit expansion trajectory, and potential value from the injection of Huali Micro's assets, leading to a higher valuation multiple. SMIC was downgraded to a "hold" rating due to a more moderate growth trend and the continued burden on the balance sheet from expansion and acquisitions.
Additionally, GigaDevice (03986) saw a net buy of HK$5.47 million. Meanwhile, Tencent (00700) and Alibaba-W (09988) experienced net sells of HK$2.199 billion and HK$1.627 billion, respectively.
