According to CoinMeta, the Shanghai Stock Exchange and China Securities Index Co., Ltd. have decided to revise the compilation scheme of the SSE Hong Kong Stock Connect index, removing securities with a daily average trading volume of less than HK$5 million over the past year. The specific measures include: removing securities that have been listed for less than one year, unless the total market value of the securities ranks among the top 10 in the respective market; using the median monthly turnover rate calculated from the securities' trading activity on the mainland market (if the company's securities are listed there for at least one year) as the monthly turnover rate; and removing securities with an average monthly turnover rate of less than 0.1% over the past 12 or 3 months, unless the daily average trading volume of such securities has exceeded HK$50 million over the past year.
