Guanghe Tech (1989.HK) opened lower and extended losses, closing the morning session at HK$112.5, down 4.7% from the previous close of HK$118.0, mainly due to persistent weakness in the Hong Kong-listed PCB sector following recent corrections, with market sentiment weighed by digestion of prior profit-alert-driven gains and lingering concerns over industry capacity expansion and client rumors. Intraday range was narrow, with only 4,100 shares traded in the morning session and total turnover of approximately HK$701,200, reflecting thin liquidity. Fundamentally, the company reported strong Q1 2026 results: net profit surged 72.88% YoY to HK$445 million, revenue rose 81.39% YoY, net margin improved to 20.51%, and EPS of HK$1.0544 was up 80.18% YoY, yet the positive impact had been priced in. Price-wise, the stock remains 49.32% below its 52-week high of HK$222, and trades well below the 20-day MA (HK$137.21) and 60-day MA (HK$166.98), confirming a bearish technical posture, though YTD gain stands at 17.19%. While CLSA and Jefferies have recently issued positive ratings on the PCB sector, near-term consolidation may continue as the market reassesses valuation.
