7月13日，康宁盘前下跌3.79%，报182.51美元/股，成交额19.24万美元。此前康宁于7月9日因板块超跌反弹大涨逾9%至201.6美元，但反弹未能延续，夜盘已下跌3.05%，盘前跌幅进一步扩大。
消息面上，康宁当前市盈率仍处百倍高位，所在光通信板块估值处于近五年99%分位水平，安全边际偏低；叠加此前高管减持及市场对光通信资本开支可持续性的担忧未消，资金在短期反弹后再度选择获利了结。期权市场此前亦出现约46.5万美元远月虚值看涨期权卖出大单，机构对上攻空间持保守态度。同板块个股Coherent同日亦下跌2.62%，行业整体承压。康宁下次财报预计于7月28日盘前发布，市场或在业绩验证前维持谨慎。
