What is an Ex-Dividend Date?
Ex-dividend describes a stock that is trading without the value of the next dividend payment. The ex-dividend date or "ex-date" is the day the stock starts trading without the value of its next dividend payment.
Typically, the ex-dividend date for a stock is one business day before the record date, meaning that an investor who buys the stock on its ex-dividend date or later will not be eligible to receive the declared dividend. Rather, the dividend payment is made to whoever owned the stock the day before the ex-dividend date.
So which Stock can you Buy now?
NMDC has declared EX_Dividend Date on 14.12.2021 and a dividend of INR 9.01 per share.
I feel you should go for it.
The last chance for you to buy is till tomorrow 13.12.2021 and do hold it. There will be a correction in Price but the Correction is supposed to survive your Dividend of 9.01 Percentage as we can see that FII has increased Holding from 4.95 to 6.83 in the Sept Quarter. So as I have shown in the Graph-Price Correction will be in that Blue zone as Institutional Buying will support the Fall.
So for every 100 Shares of value around 14790 approx, you will gain an INR 901 Dividend. But do hold for Price correction and then consolidation and selling chance.
Please take Risks on your own. No way the author is responsible for the losses you might make.
How many days after the effective date is the dividend paid?
In the case of an interim dividend, the payout to the shareholders has to happen within 30 days from the date of the announcement of the dividend. However, in the case of the final dividend, the actual payment of the dividend only has to be made within 30 days of the Annual General Meeting (AGM).
Kindly note market itself was not able to hold off but still, NMDC has held the level after price correction. It has strong resistance at 133-138. So Enjoy the dividend and wait for the right opportunity to exit.

Will update later further.
A Doji Candle was formed thus confirming both Buyer and Seller were equally active in the market.
However, we can see a slight fall again due to dividend lovers going out in between 138-133.
Wait for Price correction.
Price is correcting itself as FII and DII buyers are in the above zone.
Expect NMDC to move up in the next few days.
Trade active
NMDC has broken out of the Downward Channel and may be expected to fill up the Gap created by the Dividend.
Meanwhile, NMDC has paid the Sweet Dividend.
