6月24日，IES Holdings盘中上涨8.13%，报768.295美元/股，成交额1.15亿美元。
消息面上，标普道琼斯指数公司宣布，IES Holdings将于7月1日开盘前正式纳入标普中盘400指数，替代因被Trian Fund Management及General Catalyst Group Management收购而退出的Janus Henderson Group。指数纳入通常意味着跟踪该指数的被动基金需在生效日前后完成建仓，由此带来的增量买盘对股价形成短期支撑。IES Holdings作为全国领先的电气及通信基础设施服务商，业务覆盖数据中心、商业及住宅市场，此次入选标普中盘400指数反映了公司市值与流动性已达到中型股标准。
