Stocks after dividend.
Almost all profit-making companies pay dividends (a percentage of profit) to their share-holders, mostly once a year. The final dividend is declared at the AGM. Normally, after declaration of the dividend, the value of the stock or share of the company, traded in various stock markets comes down. This is known as stocks going ex-dividend. Depending on the strength of the company, the value may go up within a few weeks.
