6月23日，Ciena科技盘前下跌4.76%，报434.94美元/股，成交额124.8万美元，延续近期反复震荡格局。
消息面上，公司于6月12日完成28.75亿美元零息可转换优先票据私募发行，虽然发行落地消除了部分不确定性，但大规模可转债带来的潜在股权稀释担忧仍在持续消化中。此前股价因稀释预期从约523美元回调至约426美元后进入反复博弈阶段。通信设备板块整体承压，诺基亚跌7.62%，Applied Optoelectronics跌7.08%，Lumentum跌6.69%，Arista Networks跌4.33%，行业普跌对个股构成额外压力。尽管多家投行近期密集上调目标价（Argus上调至650美元、巴克莱607美元、瑞银508美元），短期市场情绪仍受稀释效应与板块联动拖累。
