It is common stock issued by me and domestic companies for domestic institutions, organizations or individuals (excluding investors from Taiwan, Hong Kong and Macao) to subscribe and trade in RMB. After several years of rapid development, China A-share market has begun to take shape. The official name of B shares is RMB special shares. It is denominated in RMB, subscribed and traded in foreign currency, and listed and traded on domestic (Shanghai, Shenzhen) stock exchanges. Its investors are limited to: overseas natural persons, legal persons and other organizations, natural persons, legal persons and other organizations in Hongkong, Macau and Taiwan Province Province, China citizens who have settled abroad, and other investors as stipulated by the China Securities Regulatory Commission. At present, B-share investors are mainly institutional investors in the above categories. B-share companies are registered and listed in China, but investors are overseas or in Hongkong, Macau and Taiwan Province Province of China. The difference between the two is that the pricing and issuing targets of A shares and B shares are different, and domestic investors obviously do not have the conditions to speculate on B shares and H shares. In addition, it is worth mentioning that B shares listed on the Shanghai Stock Exchange are denominated in US dollars, while B shares listed on the Shenzhen Stock Exchange are denominated in Hong Kong dollars, so the share prices of the two cities are quite different. If you convert US dollars and Hong Kong dollars into RMB, you will know that the share prices of the two places are basically the same. It is not standard to classify stocks by letters. According to the requirements of China Securities Regulatory Commission, stock abbreviations must be standardized. I believe that with the further development of China stock market, the appellation of A shares and B shares will become history.
