The WTI crude oil futures for March rose by 1.9%, while Brent crude oil futures for April increased by 1.86% [4][5]. - Domestic oil and gas capital expenditures are expected to gradually recover, supported by ongoing U.S. government policies promoting oil and gas development. The EIA predicts that U.S. natural gas generation capacity is expected to rise in the coming years, with overseas oil service expenditure demand also expected to rebound by 2026 [4]. Glass Fiber Sector - The glass fiber sector experienced another surge today, with stocks like Shandong Glass Fiber, Honghe Technology, International Composites, and China Jushi hitting the daily limit. Industry insiders expect a second round of price increases due to rising costs and supply tightness, with planned monthly price adjustments of 10% to 15%. If implemented as planned, prices could double by the end of the year, following a cumulative increase of over 50% since 2025 [6][7]. Optical Communication Sector - The optical communication sector performed well again today, with fiber-related stocks like Changfei Fiber and Tongding Interconnection hitting the daily limit. CPO stocks such as Tiantong Co. also reached their limits, with Tianfu Communication and Juguang Technology rising over 10%. The catalyst for this surge was a nearly 20% increase in the U.S. stock market for CPO leader Lumentum and an 8.8% rise for fiber leader Corning during the Spring Festival holiday [8][9]. - According to Guosheng Securities, the current price increase in fiber optic cables is driven by the demand from AI data centers and drones, indicating a structural change in demand. The demand for fiber optics has significantly increased due to the higher density required by AIDC and the emerging consumption market for military drones. On the supply side, the concentration of fiber optic production capacity and the long expansion cycle of optical preforms have become hard constraints, leading to continuous price increases [10].
