近日,上证、深证、中证三大系列指数相继宣布调整成分股,跟踪三大系列指数的近3000亿元指数基金也被迫调仓换股。
调整成分股
上交所、深交所、中证指数发布的公告显示,从7月2日起,上证50、上证180、上证380调整指数样本股。其中,上证50指数(1763.631,0.00,0.00%)成分股调出特变电工(7.38,0.00,0.00%)、金地集团(6.82,0.00,0.00%)、中国国航(6.17,0.00,0.00%)、西部矿业(9.46,0.00,0.00%),调入广汇股份(14.46,0.00,0.00%)、伊利股份(20.95,0.00,0.00%)、中国水电(4.42,0.00,0.00%)、方正证券(微博)(5.26,0.00,0.00%);上证180成分股调出南京高科(11.74,0.00,0.00%)、荣华实业(8.55,0.00,0.00%)、天房发展(3.73,0.00,0.00%)、吉恩镍业(14.15,0.00,0.00%)等18只股票,调入海信(微博)电器(17.73,0.00,0.00%)、中船股份(17.23,0.00,0.00%)、金发科技(5.97,0.00,0.00%)、冠农股份(20.76,0.00,0.00%)等18只股票;上证380成分股调出华能国际(6.32,0.00,0.00%)、楚天高速、中原高速(2.66,0.00,0.00%)等38只股票,调入上海电力(5.31,0.00,0.00%)、四川路桥(4.86,0.00,0.00%)、光电股份、格力地产等38只股票;深交所方面,深证成指、深证100、深证中小板、深证创业板指数均调整了成分股,其中,深证成指成分股调出露天煤业(15.29,0.00,0.00%),调入冀东水泥(16.10,0.00,0.00%),深证100指数成分股调出许继电气(17.02,0.00,0.00%)、海虹控股(6.18,0.00,0.00%)、白云山(20.21,0.00,0.00%)A等7只股票,调入古井贡酒(46.20,0.00,0.00%)、桑德环境、登海种业(21.15,0.00,0.00%)等7只股票;中证指数公司也宣布调整沪深300(2552.164,-0.45,-0.02%) 、中证100(2439.919,-0.19,-0.00%)等指数样本股。
据深圳一家基金公司基金经理介绍,根据指数编制规则,通常情况下,指数每半年就会调整成分股,大致时间主要集中在每年的1月1日和7月1日。以深证成指的编制方案为例,深证成指成分股的定期调整定于每年1月和7月的第一个交易日实施。因此,随着指数调整成分股,被动跟踪指数的指数基金也将被动调整跟踪标的。一般情况下,指数公司会提前半个月左右公布调整方案,这样指数基金就可提前调整布局。
指数基金大挪移
近两年指数基金规模大幅扩张,统计数据显示,目前投资A股市场的指数基金接近3000亿元,其中,一些规模较大的指数基金规模更是超过300亿元,因此,一旦指数调整成分股,逾千亿元的指数基金也将调仓换股。
以沪深300指数为例,目前A股市场上规模较大的指数基金主要是跟踪沪深300指数的指数基金,其中,华泰柏瑞沪深300ETF首发募集规模329.7亿份,嘉实沪深300ETF首发募集规模193亿份,一季度嘉实沪深300(LOF)资产净值为293亿元,华夏沪深300资产净值为182.68亿元,博时裕富沪深300资产净值为93.8亿份,5只跟踪沪深300指数的指数基金规模就达到1092亿元。
根据公告,从7月2日,沪深300指数成分股将大幅调整,其中调出了深圳能源(6.85,0.00,0.00%)、滨江集团(9.46,0.00,0.00%)、汉缆股份(12.56,0.00,0.00%)、首创股份(5.09,0.00,0.00%)等18只股票,调入泛海建设(4.59,0.00,0.00%)、京东方A(1.93,0.00,0.00%)、金螳螂(38.38,0.00,0.00%)、歌尔声学(33.75,0.00,0.00%)等18只股票。这些成分股的调整,使得超过1000亿元的指数基金也将被动调整资金流向。
此外,跟踪上证50指数的指数基金规模也较大,一季度华夏上证50ETF资产净值为213.2亿元,易方达上证50指数基金资产净值为201.3亿元,因此,上证50成分股的调整也将引发400多亿元的指数基金重新调整布局。
业内资深人士表示,目前各家基金公司均比较重视指数基金的发展,现在指数基金总规模接近3000亿元,再加上现在很多ETF又是融资融券标的,因此,在每年6月份、12月份指数公司宣布调整指数成分股时,市场的波动幅度就会比较大。
