納入標普道瓊斯指數的上市公司包括147只大盤股,251只中盤股,701只小盤股,它們以25%的納入因子納入之后,預計A股在該指數中所占權重為6.2%,預計中國市場整體(含A股、港股、海外上市中概股)在該指數中所占權重為36%。此次納入名單中不含創業板股票。這也是近一段時間來各大國際指數對A股的第三次擴容或納入。

未來,隨著中國企業全球化的進程開始實現大跨度的發展,海利爾將會更加充分地利用國際市場和資源,強化其國際化屬性,建立全球競爭優勢。公司管理層會繼續扎實做好產品和市場,堅持積極穩健的經營策略,從而實現更好的業績來回報廣大投資者。而此次被納入標普道瓊斯指數本身也將增強公司的市場關注度,提高海利爾在資本市場的影響力,有望獲得國際長線投資者的青睞。
