On May 26, Sunny Optical Technology (02382.HK) fell 3.96% in regular trading, trading at HK$70.35/share, with trading volume of HK$612 million.

According to media reports, a major client of Sunny Optical Technology plans to reduce its smartphone component procurement by approximately 30% and will lower its second-half smartphone shipment forecast. The news triggered broad selling pressure across the mobile phone supply chain, with peer AAC Technologies also experiencing downward pressure.

The stock had previously rallied over 8% across two consecutive sessions, driven by optimism surrounding Apple inventory restocking, AI optical interconnect expectations, and a new strategic cooperation agreement with Chengdu Guangming. However, the major client order cut abruptly reversed short-term sentiment. The company's chairman had earlier stated that overseas major client revenue would achieve over 100% growth this year, with the group targeting RMB 100 billion in sales, making the reported procurement reduction a notable headwind for near-term investor confidence.
