A redução da participação da SMIC foi causada pela diminuição do tamanho do ETF do índice de ações de ciência e tecnologia da China na Xangai-Hong Kong Stock Connect.

A Shanghai Stock Exchange ChiNext Board 50 ETF reduced its holdings of 2.8103 million shares of domestic stocks, according to Jinshi Data on February 22. It was announced by SMIC International on February 21. It was found that the reduction was mainly due to the reduction in the size of the Shanghai Stock Exchange ChiNext Board 50 ETF. So far this year, the Shanghai Stock Exchange ChiNext Board 50 ETF has experienced net redemptions of nearly 13 billion yuan. According to industry experts, due to the large size of some ETFs, they have had a significant impact on listed companies.
