On the news front, global demand for AI computing power continues to explode, and optical communication, as the core infrastructure for data center interconnection, has recently gained significant market attention. Institutions point out that the "memory tax" effect is driving up costs across the entire AI infrastructure supply chain, while optical fibers and cables, as the "veins" of the computing network, have seen their demand elasticity amplified in this round of capacity expansion. YOFC, as the world's largest supplier of optical fiber preforms and optical fibers and cables, directly benefits from the capital expenditure growth cycle of domestic and foreign operators and cloud providers. Meanwhile, the central bank's Q1 monetary policy report removed references to "reserve requirement ratio cuts and interest rate cuts," leading to a stabilization of short-term liquidity expectations, with funds more inclined to allocate to high-growth sectors with strong performance certainty. From a technical perspective, the current stock price has significantly risen above the short-term moving average system, and the 5-day and 10-day moving averages are likely to form a bullish arrangement today
