Tongding Interconnection said its shares experienced abnormal trading volatility after a sharp three-day decline. According to Jin10, the company issued an announcement stating that its stock’s cumulative closing-price deviation exceeded 20% over three consecutive trading days on June 29, 2026, June 30, 2026, and July 1, 2026, meeting the criteria for abnormal fluctuations under relevant Shenzhen Stock Exchange trading rules. The company said it has noticed heightened market attention on the optical fiber and cable sector. It added that the sustainability of short-term price fluctuations in optical fiber products is uncertain, and the impact on its future performance would need to be assessed based on future market conditions and the company’s business progress, which also remains uncertain. Tongding Interconnection said decisions on resuming and expanding optical fiber production require consideration of multiple factors, including optical fiber market prices, supply-demand dynamics, and the supply capacity of fiber preforms.
