通信行业动态或提振PCB需求 中京电子股价近期震荡

Group 1 - The communication industry is experiencing significant activity, which may indirectly impact Zhongjing Electronics (002579) as a PCB supplier. Recent trends in AI hardware demand and supply shortages in the optical fiber and cable sector are expected to boost PCB demand, as PCBs are fundamental components for optical modules and communication devices [1] - The stock price of Zhongjing Electronics has shown volatility over the past week, with a maximum price of 11.90 yuan on February 10 and a minimum of 11.30 yuan on February 6, resulting in a price fluctuation of 17.97%. As of February 13, the closing price was 11.64 yuan, reflecting a 1.57% increase over five days but a 6.43% decline over twenty days, underperforming the market [2] - Brokerage firms maintain a positive outlook on related industry trends but caution about valuation risks. Reports indicate that the optical fiber and cable industry has a high short-term success rate due to AI demand affecting traditional capacity. However, PCB companies like Zhongjing Electronics need to penetrate high-end products and control costs to achieve performance elasticity [3] Group 2 - The optical fiber demand in global data centers has increased by 75.9% year-on-year, with high-end products like hollow-core fibers seeing accelerated industrialization. This surge in demand is expected to lead to a sustained increase in prices [1] - The trading volume for Zhongjing Electronics peaked at 240 million yuan on February 10, with a turnover rate of 3.49%, indicating a recent high in trading activity. However, the latest turnover rate has decreased to 1.89%, suggesting a decline in trading activity [2] - The expansion cycle for upstream optical fiber preform rods is projected to last 2-3 years, reinforcing supply rigidity and the sustainability of price increases. The PCB sector's price-to-book ratio is currently at historical highs, necessitating fundamental support for valuation [3]
