A more thorough explanation:

X can have different meanings depending on the context:

1. EX DIVIDEND: A term used in finance to indicate that a stock is trading without the value of the next dividend payment. For example, if a company pays a dividend of $1 per share and the ex-dividend date is on June 1st, then investors who buy the stock on or after June 2nd will not receive the dividend payment.
2. EX RIGHTS: A term used in finance to indicate that a stock is trading without the right to participate in a new issue of shares. For example, if a company announces a new issue of shares and sets an ex-rights date, then investors who buy the stock on or after that date will not be able to participate in the new issue.
3. EX DISTRIBUTION: A term used in finance to indicate that a stock is trading without the value of a distribution, such as a bonus issue or a spin-off. For example, if a company announces a bonus issue of shares and sets an ex-distribution date, then investors who buy the stock on or after that date will not receive the bonus shares.
4. EX WARRANTS: A term used in finance to indicate that a stock is trading without the right to receive warrants. For example, if a company issues warrants to its shareholders and sets an ex-warrants date, then investors who buy the stock on or after that date will not receive the warrants.
5. X: A mark or symbol used for different purposes, such as:
• A signature mark for a person who is physically handicapped or illiterate. This mark is usually accompanied by the signer's name and requires two signing witnesses in addition to a notary public if it needs to be notarized.
• A symbol equivalent to "by" when used in giving dimensions, such as 3 x 5 inches.
• A mark placed on a document, such as an application or a ballot, to indicate a selection, such as "yes" or "no".

• EX DIVIDEND: If a stock is trading at $50 per share and pays a dividend of $1 per share, then its ex-dividend price would be $49 per share. An investor who buys the stock on or after the ex-dividend date would not receive the $1 dividend payment.
• EX RIGHTS: If a company announces a new issue of shares at a price of $10 per share and sets an ex-rights date, then its ex-rights price would be lower than $10 per share. An investor who buys the stock on or after the ex-rights date would not be able to participate in the new issue.
• EX DISTRIBUTION: If a company announces a spin-off of one of its subsidiaries and sets an ex-distribution date, then its ex-distribution price would be lower than its previous price. An investor who buys the stock on or after the ex-distribution date would not receive the shares of the subsidiary.
• EX WARRANTS: If a company issues warrants to its shareholders and sets an ex-warrants date, then its ex-warrants price would be lower than its previous price. An investor who buys the stock on or after the ex-warrants date would not receive the warrants.
• X: A person who is illiterate or physically handicapped may use an X mark as a signature on a document, such as a contract or a will. The X mark needs to be witnessed by two other people and notarized by a notary public to be valid.
• X: A carpenter may use an X mark to indicate the location of a nail or a screw on a piece of wood. The X mark helps to ensure that the nail or screw is placed in the right spot.
• X: A voter may use an X mark to indicate a vote on a ballot. The X mark helps to indicate the voter's choice and prevent confusion or errors.

The examples illustrate how X can have different meanings and uses depending on the context. In finance, X is used to indicate that a stock is trading without certain rights or values. In other contexts, X is used as a mark or symbol to indicate a signature, a location, or a selection.
