If I buy shares today when the ex date for dividend payout is tomorrow, would i still receive the dividend payout even though it takes a few days to process the transaction?

Simply put, YES.

Yes. Think of Ex Date as the books closing date. As long as the company books recognise you as holding on to their shares, you get paid dividends on the Pay Date.

Just a question. Ex Date is normally not known until the management of a company declares it. Besides, we also don't know the dividends they plan to pay. So... are you referring to Pay Date of the dividends instead?

In which, then NO to your question. As long as you don't own stocks before the Ex Date, you are not getting paid on Pay Date.

Hope this clarifies.

Cheers
