科技行业周报：光模块、存储、液冷等行业近况更新-20251117

Investment Rating - The report does not explicitly state an investment rating for the industry but suggests a focus on companies with strong delivery capabilities and market positioning in the light module and storage sectors [3]. Core Insights - The light module industry is transitioning from order expectations to actual deliveries, with significant implications for stock prices and future growth [3]. - The storage cycle is expected to last longer than previous cycles, potentially extending to 2-3 years due to heightened demand and supply constraints [5]. - The AI sector is driving new demand for storage solutions, as data needs to be activated and stored for model training and other applications [8]. Summary by Sections Light Modules - Demand for 800G light modules is projected at 55 million units, while 1.6T demand is estimated at 30 million units, with Nvidia and Google being major contributors [3]. - Supply chain dynamics indicate a normal decline in prices, with profit margins expected to remain strong despite supply shortages [3]. - Key players in the light chip market, such as Lumentum, are raising prices by 10-20%, benefiting upstream suppliers [3]. - Domestic companies like Source Technology and Yunling Optoelectronics are positioned to enter the global supply chain due to upstream shortages [3]. Storage - The storage cycle is anticipated to be longer than usual, with a potential duration of 2-3 years due to increased demand and supply shortages [5]. - Domestic companies like Changxin Storage and Yangtze Memory Technologies are expected to ramp up production, alleviating supply constraints [5]. - The report highlights the impact of rising prices on mid-to-low-end consumer electronics, which may face profitability challenges [5]. AI-Driven New Fields - The AI era necessitates the activation of cold data into hot data for model training, creating new storage demands [8]. - Supply-side constraints are evident as overseas manufacturers are not expanding production, leading to a mismatch in supply and demand [8]. - Recommended companies in the storage module sector include Jiangbolong, Demingli, and Bawei Storage, each with unique strengths [8]. Liquid Cooling - The liquid cooling market is expected to see growth, particularly in overseas markets, with domestic companies yet to capitalize on this trend [10]. - Companies like Vertiv and Honeywell are leading in the overseas liquid cooling space [10]. Domestic Computing Power - The progress of domestic computing power construction is slow due to unclear policies on imported computing cards and compatibility issues [13]. - Companies like H Company, Cambrian, and Alibaba's T-head are highlighted as key players in the domestic computing power landscape [13]. Energy Storage and Photovoltaics - The energy storage sector is experiencing high demand, with certain suppliers already booked through mid-2026 [13]. - The photovoltaic industry is facing general market uncertainty, with speculation around its connection to U.S. energy shortages [13].
