中新网上海11月28日电 (高志苗)中证指数有限公司(以下简称中证指数公司)28日发布消息称,日前中证指数公司宣布将调整沪深300、中证500、中证1000、中证A50、中证A100、中证A500等指数样本,此次调整为指数样本的定期调整,将于12月12日收市后正式生效。
根据指数规则,经指数专家委员会审议,沪深300指数更换11只样本,华电新能、东山精密等调入指数;中证500指数更换50只样本,和而泰、华虹公司等调入指数;中证1000指数更换100只样本,仕佳光子、永鼎股份等调入指数;中证A50指数更换4只样本,中际旭创、华工科技等调入指数;中证A100指数更换6只样本,东方财富、中科曙光等调入指数;中证A500指数更换20只样本,国泰海通、芯原股份等调入指数。除上述指数之外,其他指数的样本也将进行相应的调整。
本次样本调整后,信息技术、通信服务与工业等行业样本数量及权重普遍上升,A系列指数较传统宽基指数行业配比更加均衡,新质生产力含量进一步提升,有助于指数发挥服务国家战略、引导资源配置的作用。
沪深300指数中信息技术、通信服务行业样本数量分别增加4只、2只,权重分别上升1.46%、0.75%。中证500指数中工业行业样本数量增加11只,权重上升2.48%。中证1000指数中,通信服务、工业行业样本数量分别增加6只、2只,权重分别上升0.44%、0.37%。调整后,上述指数中科创板及创业板样本合计数量分别增加3只、6只、9只,合计权重分别达到21.26%、28.07%、36.16%,科创、创新属性进一步增强。
A系列指数以“均衡”应对市场变化,中证A50、中证A100、中证A500指数中信息技术、通信服务行业权重增幅居前,金融行业在调整后均有不同程度的下降。中证A500指数中新兴行业样本权重约51.23%,较调整前权重上升0.79%。调整后,中证A50、中证A100和中证A500指数分别覆盖30、28、35个中证二级行业以及50、46、89个中证三级行业,实现对细分行业龙头公司的覆盖。(完)
