智通财经APP获悉，日经公司周四宣布，日本芯片制造商铠侠控股株式会社及运营“唐吉诃德”折扣店的泛太平洋国际控股株式会社，将于4月1日正式被纳入日经225股票指数。
指数编制方表示，存储器制造商铠侠凭借其极高的流动性获纳入;而泛太平洋的入选则源于对各行业板块成分股进行的调整。与此同时，GS Yuasa Corp.和卡西欧计算机公司将被剔除出该指数。
由于追踪该指标的被动型基金将根据指数调整进行买卖操作，此次成分股变动可能对相关公司的股价产生影响。
受益于人工智能需求推高内存价格，铠侠今年股价已飙升95%，成为全球表现最佳的股票之一。泛太平洋国际的股价亦上涨约10%，涨幅与日经225指数基本持平。
理索纳控股策略师Hiroki Takei表示：“从供需角度看，被纳入主要指数往往对个股构成利好。”他补充称，鉴于日本股市过去几日经历了“广泛回调”，此次成分股纳入或将成为一个尤为积极的催化剂。
