7月21日，Tradr 2X Long SNDK Daily ETF盘前上涨13.71%，报15.84美元，成交额1871.09万美元。该ETF为闪迪两倍杠杆做多产品，闪迪盘前涨超6%直接推动杠杆效应放大涨幅。
消息面上，存储板块延续反弹走势，华尔街多家机构逆势上调闪迪目标价，高盛上调至2200美元，Evercore ISI上调至3100美元，机构普遍看好8月初即将公布的财季业绩表现。大摩指出内存正日益成为AI基础设施建设的主要瓶颈，维持对存储板块积极判断，将近期回调定性为买入窗口。瑞银认为动量股抛售接近尾声，建议投资者逐步重建AI与半导体头寸。此前闪迪7月累计跌幅超40%，短期超跌后技术性反弹需求叠加机构看多共振，带动杠杆产品涨幅持续扩大。
