On August 16, Hang Seng Indexes announced the HSI review results for the first half of the year, including Yangtze Optical Fibre and Cable Joint Stock Limited Company (YOFC, 06869.HK) in the HK Equities HSI ,expected to become effective on September 4, 2017. Which reflects the performance of qualified Hong Kong-listed stocks traded through HK Equities. According to the results, there are 34 stocks including YOFC, China Overseas Grand Oceans Group and LVJING (China) Real Estate included in the HSI and 13 stocks excluded from the HSI. (See the table below)

YOFC's listing on Hong Kong's stock exchange in 2014 witnessed the listing of China's first and only company in Hong Kong that specialized in optical fibre performs, optical fibre and cables. This successful inclusion in the HSI marks another breakthrough following YOFC's inclusion in MSCI Global Small-Cap China Index in 2015 and its inclusion in small-middle-cap HSI constituent stocks in 2017 , and also reflects the high recognition of Hong Kong's capital market towards YOFC.

As analyzed by many well-known financial securities media, the inclusion in the index is a way for domestic investors to trade Hong Kong listed stocks. Once included in the Shenzhen-Hong Kong Connect, trading volume for a stock could double. Therefore, it is very important for Hong Kong stocks to obtain the qualification.
