I saw someone asking in the investment group about CA, so I want to share the knowledge I've gathered because these symbols are quite important if you want to trade stocks safely.

What exactly is a CA? This abbreviation stands for Corporate Action, which means the company is about to have some kind of movement within 7 days. It could be dividend payments, shareholder meetings, or other matters related to our rights as shareholders. If you want to know the details, just click to view that CA. It will show what event is going to happen and when.

What you need to know is that these symbols are grouped according to the suffix attached to the stock, such as the group starting with X, which stands for Excluding. This means investors will not receive certain rights. For example, XD (Excluding Dividend); if you buy now, you won't get the dividend this round, but if you hold until the next round, you will.

There are many more, such as XM, which means no voting rights at the shareholder meeting; XR, which means no rights to subscribe for new shares; XW, related to warrant rights; or XN, related to capital reduction. These differ depending on the rights the company is about to grant.

Additionally, there is a group T related to speculation. Stocks marked with T1, T2, T3 are stocks whose prices have risen too high. The stock exchange has implemented measures such as T1, which requires cash-only purchases; if prices keep rising, it moves to T2, which prohibits using these stocks as collateral; and if it reaches T3, the restrictions are even stricter, forbidding offsetting.

There are also several warning symbols, such as H (Trading Halt), meaning trading is temporarily paused; SP (Trading Suspension), which lasts longer than H; NP, indicating the company has reporting issues; NC, meaning the company might be delisted from the market; and C (Caution), which warns that the company has high financial risk.

In fact, understanding these symbols can help us make better investment decisions, whether it's avoiding risks or knowing what rights we will receive from holding shares. Investing with knowledge is definitely better than investing blindly.
