On June 17, Sunny Optical Technology rose 4.16% in regular trading, trading at 79.35 HKD/share, with turnover of 134 million HKD.

On the news front, Goertek announced a renewed partnership with Sunny Optical, committing 1 billion yuan to the XR (extended reality) segment. Concurrently, the optical communication concept sector has continued to strengthen in recent sessions. Institutions noted that prior sector pullbacks do not alter the positive fundamental trend, and the company's micro-nano optical technology penetration into AI data center optical interconnect applications represents a new business catalyst. The combination of the XR collaboration materializing and optical communication tailwinds has collectively boosted market sentiment.

The optical communication sector saw broad gains earlier this week, with peers such as Xzhi Technology-P rising over 15% and Cambridge Technology gaining nearly 8%, reflecting sustained institutional optimism toward the CPO/NPO supply chain outlook. However, overhang from a major customer reportedly cutting smartphone component procurement by approximately 30% has weighed on shares since early June, creating short-term volatility around the stock's recovery trajectory.
