如何理解股票代码标识？XD哈高科标识有何含义？

Core Points - Understanding stock codes is essential for investors as they serve as an "ID" for each stock, helping to quickly identify different stocks and reflecting basic information such as the exchange and listing sector [1][2] - Stock codes are composed of numbers or letters, with different exchanges and sectors having distinct coding rules. For instance, A-shares on the Shanghai Stock Exchange start with 60, while those on the Shenzhen Stock Exchange start with 00 [1] - Special stock code identifiers, such as "XD" for Ex-Dividend, indicate specific events like dividend distribution, affecting stock price adjustments on the respective dates [1] Summary of Identifiers - "XD" indicates the stock is on the ex-dividend date, meaning the stock price will adjust based on the dividend distributed [1] - "XR" stands for Ex-Right, indicating the date after a company has distributed rights or shares [1] - "DR" means Ex-Right and Dividend, indicating both rights and dividends have been distributed [1] - "ST" signifies Special Treatment for companies with abnormal financial situations, while "*ST" indicates a warning of delisting risk [1] Investment Considerations - Investors should pay attention to these special stock code identifiers, as buying stocks on ex-dividend dates means they will not receive the dividend despite potential price drops [1] - Caution is advised when dealing with "ST" and "*ST" stocks due to associated operational risks [1]
