Stock is a certificate produced by a joint-stock cooperative limited liability company to prove that shareholders of the company have the right to use part of the company's assets. The shares of China enterprises are sold in Beijing Stock Exchange, Shanghai Stock Exchange and Shenzhen Stock Exchange, and investors generally register and open accounts in securities brokerage companies.

Every stock has an xd in front of it, which proves that today is the dividend day of this stock. xd is the abbreviation of (except) Exclude (interest). Investors who purchase on or after the ex-dividend date will no longer enjoy the right to dividends. These people must choose the dividend distribution before the end of the registration day. The calculation method is ex-dividend price = closing price on the registration date-discovery money per share.
