What does ex date and record date mean?
The concept of Ex-date and Record date is applicable to Dividends, Bonus issue, Splits & other corporate actions.
The record date is the cut-off date established by a company in order to determine which shareholders are eligible to receive a dividend or distribution.
The ex-date as the name suggests is the date on which the stock trades without the dividend/bonus/split value included in it. Normally the price of the stock will drop to the extent of the dividend/bonus/split declared on the ex-dividend date. It is generally 2 days prior to the record date.
