Core Viewpoint - The computing power sector has experienced a significant surge, becoming one of the most attractive investment themes in the A-share market, driven by factors such as relaxed sales policies from Nvidia, increased capital expenditure from North American cloud providers, and a surge in global AI model releases [2][6]. Group 1: Market Performance - The computing power sector saw a notable increase in various sub-sectors, particularly on August 13, with companies like Cambricon reaching a peak stock price of 868 yuan, closing at 860 yuan, with a total market capitalization of 359.8 billion yuan [3]. - Industrial Fulian also hit a historical high, closing at 43.68 yuan per share, with a single-day trading volume exceeding 10 billion yuan, reflecting strong market interest in AI server leaders [3]. - In the optical module sector, companies such as NewEase and Zhongji Xuchuang experienced significant stock price increases, with NewEase rising by 15.55% to 236.56 yuan and Zhongji Xuchuang increasing by 11.66% to 252 yuan [3]. Group 2: Computing Power Leasing Concept - The computing power leasing concept showed strong rebounds, with companies like Hangang Co. hitting the daily limit, and other related stocks such as Yuke De and Hongbo Co. also seeing significant gains [4]. - Analysts noted that the explosive growth in AI model training and inference demand has redefined computing resources as the "new oil" of the digital age, leading to a reassessment of companies with stable computing power supply [4]. Group 3: Liquid Cooling Technology - Liquid cooling technology, a key component of computing infrastructure, has attracted significant investment, with stocks like Southern Pump Industry and Yonggui Electric rising over 12% [4]. - The strong performance of the liquid cooling sector is attributed to multiple factors, including the increasing power consumption of Nvidia's GB300 chip and a surge in orders for liquid cooling equipment from global cloud providers [4][5]. - The global liquid cooling market is projected to exceed 200 billion yuan by 2025, with China accounting for 35% of this market [5]. Group 4: Driving Factors - Four main factors are driving the rise of the computing power industry: Nvidia's relaxed sales policies towards China, explosive capital expenditure growth from North American cloud providers, the dense release of global AI models, and breakthroughs in the domestic computing power supply chain [6][7][8]. - Nvidia's potential permission to sell AI chips to China has injected confidence into the computing power supply chain, leading to a collective rise in Nvidia-related stocks [6]. - Capital expenditure from major tech companies like Google, Microsoft, and Amazon reached 159.384 billion USD in the first half of 2025, marking a 24.4% year-on-year increase, indicating strong demand for AI infrastructure [7]. - The release of advanced AI models, such as OpenAI's GPT-5, has further fueled the demand for computing power, with industry leaders pushing for rapid technological iterations [8].
