Core Viewpoint - The report from Guotai Junan indicates that the price increase of traditional fiberglass electronic cloth has accelerated since February, confirming the view that the shift of weaving machine capacity to AI electronic cloth has led to a supply shortage of traditional cloth [1][2]. Group 1: Price Increase and Supply Shortage - The price of traditional electronic cloth has risen significantly in February, with the first week of February seeing prices for 7628 electronic cloth ranging from 4.9 to 5.45 yuan per meter, an increase of 0.5 to 0.6 yuan per meter compared to the previous month [2]. - The announcement from Taiyao Technology on February 10 regarding reduced supply of E-glass products due to strong demand for low-dielectric materials has further fueled expectations of a shortage in traditional cloth [2]. Group 2: Inventory Levels and Profitability - Current inventory levels for leading traditional electronic cloth manufacturers are only two weeks, compared to a normal level of 1 to 1.5 months, primarily due to the impact of weaving machines shifting to produce AI specialty cloth [3]. - The expected increase in prices is likely to boost profitability for leading companies, with China Jushi's traditional electronic cloth capacity at 1 billion meters and Jiantao's at 800 million meters [3]. Group 3: AI Electronic Cloth Demand - The shortage of traditional cloth and the strong demand for AI electronic cloth are interconnected, with 2026 expected to be a year of realization for AI specialty cloth demand [4]. - The demand for CTE cloth has been driven by the packaging board needs of AI chips and consumer electronics, while low-dielectric cloth is expected to see stable demand from specific applications [4]. Group 4: Recommended Stocks - The report recommends investment in China Jushi (600176.SH), Jiantao Laminated Board (01888), and China National Materials (002080.SZ), along with related companies such as International Composites (301526.SZ) and Honghe Technology (603256.SH) [5].

Core Viewpoint - The report from Zhongtai Securities indicates that electronic fabric prices have experienced two rapid increases since early 2026, reflecting a tight supply situation in the industry, particularly in the weaving segment [1][2]. Group 1: Price Trends - Electronic fabric prices have risen significantly during the traditional off-season, with Linzhou Guangyuan's 7628 fabric price increasing by 0.55 yuan to 5.40 yuan (+11%) and International Composite's 7628 fabric price rising by 0.55 yuan to 5.20 yuan (+12%) [1]. - The price increase trend has accelerated, confirming a supply-tight situation in the market [1]. Group 2: Supply-Demand Dynamics - The core supply issue lies in the midstream weaving segment, with a projected supply-demand balance for electronic yarn in 2026 showing supply growth of 6.1% versus demand growth of 6.6%, establishing a basis for price increases [2]. - The demand for low-Dk and low-CTE specialty thin fabrics driven by AI applications is increasing, leading to a thinner product structure across the industry and a decline in weaving efficiency [3]. Group 3: Weaving Equipment Shortage - The shortage of weaving machines is expected to extend the supply gap in the industry, with Japan's Toyota being a major supplier of electronic fabric weaving machines, which have a long delivery cycle [4]. - The supply gap for weaving machines is estimated to reach 6.1% in 2026 and potentially 10.6% in 2027, indicating a persistent supply-demand imbalance [5]. Group 4: Investment Recommendations - The report suggests focusing on leading companies with production scale and cost advantages, such as China Jushi (600176), which is expected to maintain a strong performance during the price increase cycle due to its significant capacity [6]. - Other recommended companies include Zhongcai Technology (002080), International Composite (301526), and Honghe Technology (603256), which have both traditional electronic fabric performance and a presence in specialty electronic fabrics [7].
