CA stands for Corporate Action, which refers to actions taken by a company that will occur within seven days. When a stock has a CA, you can click to see detailed information about what it is and when it will happen.

These warning symbols are divided into three main categories, each with different meanings and impacts on your investments. Understanding the basics of each category will help you make better decisions.

X Group: Rights to Lose

Abbreviations starting with X indicate “Excluding,” meaning investors will not receive certain rights. There are various types:

XD (Excluding Dividend): If you buy the stock at the XD date, you won’t receive dividends for this cycle. However, if you hold the stock until the next XD date, you will receive the next dividend.
XM (Excluding Meetings): No rights to attend shareholder meetings, where important company decisions are made.
XW (Excluding Warrant): No rights to purchase warrants (convertible securities that can be exchanged for shares).
XR (Excluding Rights): No rights to subscribe for new shares, usually issued to raise additional capital.
XS, XT, XI, XP, XA, XE, XN, XB: Each has different rights, from principal and interest to conversion rights and refunds from capital reduction.

Common Question: You can check the stock calendar on the stock exchange website to see when stocks go XD. Also, to receive dividends, buy the stock just before the XD date.

T Group: Speculation Restrictions

Stocks marked with T indicate that their prices have surged excessively with high speculation. The stock exchange implements measures divided into three levels:

T1 (Trading Alert Level 1): Must buy with a Cash Balance account only, for three weeks after announcement.
T2 (Trading Alert Level 2): Must buy with cash only, and cannot use this stock as collateral. Also for three weeks.
T3 (Trading Alert Level 3): Most restrictive: only cash account purchases, no collateral use, and no net settlement. This means after selling, the buying power is restored the next day instead of immediately.

These measures aim to prevent multiple trades within a day and reduce speculative risks. Cash Balance accounts are suitable for beginners, as they limit trading to the actual funds in your account.

Besides the above, there are other warning symbols indicating stock risks:

H (Trading Halt): Temporarily suspends trading for one session (morning and afternoon sessions). Usually due to significant news not yet announced to the market.
SP (Trading Suspension): Suspends trading for more than one session, more severe than H.
