Main takeaway: SemiAnalysis drew criticism for shorting the optics sector then joining an optics ETF. The firm’s June report warned of low CPO yields and delays, triggering stock drops, then it and Tema ETFs created an optics ETF that later held firms it had previously criticized.
BlockBeats 消息,7 月 5 日,Serenity 援引 UDN Money 报道称,研究机构 SemiAnalysis 因一系列操作引发市场争议。SemiAnalysis 于今年 6 月发布研报,以 CPO(共封装光学)技术良率偏低、产品发布时间可能推迟等理由看空光通信板块,导致相关板块股价大幅下跌。随后,该机构与 Tema ETFs 合作推出一只光通信主题 ETF。值得注意的是,SemiAnalysis 此前在《Powered Down, Lights Off》报告中重点看空的 Himax Technologies 和 Lumentum Holdings 等公司,在光通信板块回调后均被纳入该 ETF 持仓,引发市场对其「先唱空、后配置」行为的讨论。
