RE: Ex-Dividend for 12.34p p/share29 Mar 2016 01:22
Au contraire ... I'm right ... and rather than post a link to a page that simply tells me the share price of SL and maybe confirms the exDiv date itself I'll give you a link to an appropriate article/definition ...
https://en.wikipedia.org/wiki/Dividend#Dividend_dates
Where you will find the following, confirmatory, definition ...
"In-dividend date — the last day, which is one trading day before the ex-dividend date, where the stock is said to be cum dividend ('with [including] dividend'). In other words, existing holders of the stock and anyone who buys it on this day will receive the dividend, whereas any holders selling the stock lose their right to the dividend. After this date the stock becomes ex dividend.
Ex-dividend date — the day on which shares bought and sold no longer come attached with the right to be paid the most recently declared dividend. In the United States, it is typically 2 trading days before the record date. This is an important date for any company that has many stockholders, including those that trade on exchanges, to enable reconciliation of who is entitled to be paid the dividend. Existing holders of the stock will receive the dividend even if they sell the stock on or after that date, whereas anyone who bought the stock will not receive the dividend. It is relatively common for a stock's price to decrease on the ex-dividend date by an amount roughly equal to the dividend paid. This reflects the decrease in the company's assets resulting from the declaration of the dividend."
As you will see the right to the dividend is dependant on a 'single point in time', the start of trade on the ExDiv day, and not a 'period of time' as you allude to in your posting ... put simply what you suggest is and would be totally unworkable.
And the final acid test ... I've sold between the ExDiv day and the record date and STILL got the dividend ...
BTW the record date is two days later to allow the company registrar to catch up with the trading that has occurred.
... and if you need any further clarification, talk to your broker ... here's what Barclays have to say ...
"For example, if the ex dividend date for a stock is on 3rd March, then to be entitled for the dividend payment you must hold the stock as of midnight of 2nd March."
