8月21日，Moderna夜盘下跌3.27%，报128.96美元/股，成交额89.01万美元。此前该股因mRNA癌症疫苗三期试验成功单日暴涨177%后，已连续两个交易时段遭遇获利回吐。
消息面上，Moderna与默沙东联合宣布个性化mRNA癌症疫苗intismeran autogene联合Keytruda的III期试验达到主要终点，推动股价单日暴涨177%、市值增加440亿美元。随后市场快速降温，瑞银报告显示客户在暴涨当日即净卖出4400万美元Moderna股票。期权市场同步出现偏空信号，包括167万美元远期虚值PUT买入及熊市看涨价差，显示部分资金在压制上行空间并为回撤做准备。尽管多家投行大幅上调目标价（美银由40美元升至170美元、杰富瑞升至150美元），但短期获利了结压力仍主导股价走势。
