I just noticed that friends in the investment group are often confused by the abbreviations attached to stocks, such as CA, XD, T1, so I want to share some knowledge I’ve learned to make it easier for everyone to understand.

Starting with the most common symbol, CA. CA stands for Corporate Action, which means that the stock will have some kind of movement within the next 7 days. When you see a CA, click to see what event is happening and when. Each abbreviation has a different meaning.

The letter X at the end of a stock usually indicates that investors will not receive certain rights, such as XD (Excluding Dividend). If you buy at the XD date, you will not receive this round’s dividend, but if you hold until another XD date, you will receive the next dividend. XM (Excluding Meetings) means you do not have the right to attend the shareholders’ meeting. XR (Excluding Rights) means you do not have the right to subscribe for new shares, which is often related to capital increase.

For stocks with a T at the end (T1, T2, T3), it indicates that the stock has surged significantly, and the stock exchange has implemented trading restrictions. T1 is the first level, where trading must be in cash only. T2 still requires cash and cannot be used as collateral. T3 is the strictest; in addition to requiring cash and prohibiting collateral, multiple trades in a single day are also forbidden.

Other warning symbols to watch out for include: H (Trading Halt), meaning trading is temporarily halted for one period; SP (Trading Suspension), which lasts longer than one period; NC (Non-Compliance), indicating the company may be subject to delisting; and C (Caution), warning that the company has financial problems or high risk.

Understanding these CA symbols and other indicators helps us avoid risks and make better investment decisions. Whenever you see strange abbreviations, study them so you don’t walk into unexpected situations.
