On the news front, U.S. optical communications concept stock Marvell Technology significantly raised its revenue forecast.

Guosheng Securities noted that as we enter June, demand expectations for optical modules in 2027 are becoming clearer. The supply constraints for key upstream components that previously limited deliveries are also gradually reaching an inflection point towards improvement. Leading manufacturers' production capacity and earnings potential are expected to accelerate. The firm suggests refocusing on the major 'optical' theme at this stage, with particular emphasis on the two leaders, Zhongji Innolight and Eoptolink Technology Inc.
