8月18日，iShares费城交易所半导体ETF(SOXX)盘中下跌5.07%，报528.97美元，成交额12.71亿美元。
消息面上，多重利空因素叠加压制半导体板块。日本第三轮半导体设备出口管制新规已正式生效，将先进封装全链条核心设备纳入严苛管控清单，采用逐案审批模式，驳回率接近70%-80%，变相对产业链形成实质性断供，加剧市场对全球芯片供应链扰动的担忧。
与此同时，期权市场机构资金对半导体核心标的普遍呈偏空态度。英特尔出现合计近900万美元CALL卖出压顶，AMD出现114万美元远期Put押注跌破490美元，美光科技亦遭远月虚值Call卖出布局，整体显示机构认为板块短期上行空间受限。此外，谷歌与AMD合作开发下一代TPU的消息引发市场对芯片竞争格局生变的忧虑。
