Ex-Date vs Record Date

The record date is the day a company reads its shareholder register to decide who receives a dividend, bonus, split or rights entitlement. The ex-date is the first trading day on which buying the share no longer earns that entitlement. In India both dates now fall on the same day, because T+1 settlement closed the gap that used to separate them — a change many older guides still miss.

The two dates exist because ownership does not transfer the moment a trade happens. When you buy a share on the NSE or BSE, it reaches your demat account one working day later. The company cannot watch the exchange to see who is buying; it can only ask the depositories — NSDL and CDSL — for a list of everyone holding the share at the end of one chosen day. That chosen day is the record date, and the ex-date is the market's way of announcing, in advance, which trades will settle in time to make that list.

Why does the ex-date exist if the record date decides everything?

Strictly, only the record date matters: whoever appears in the depository's end-of-day list receives the entitlement. But a buyer on the exchange has no way of judging, mid-session, whether a trade struck today will reach their account before that list is drawn. So the exchange publishes the ex-date alongside every corporate action. From that day onward, a purchase settles too late to qualify, and the share is said to trade ex-dividend, ex-bonus or ex-split — without the benefit attached.

This also explains why the entitlement follows the demat account, not the trading screen. Shares held jointly, pledged, or received through an off-market transfer are all judged by the same test: were they sitting in the account at the close of the record date? The split of roles between the account that holds and the account that trades is covered in our demat account vs trading account guide; for corporate actions, the demat side is the one that counts.

How T+1 settlement made both dates fall on the same day

Under the old T+2 cycle, a trade took two working days to settle, so the ex-date sat one trading day before the record date: buy on or after the ex-date and your shares would arrive a day too late. When Indian equities completed the move to T+1 settlement in January 2023, the arithmetic changed. A purchase made one trading day before the record date now settles on the record date itself, in time for the register. Only a purchase on the record date arrives late.

The exchanges responded by aligning the two, and that is how NSE and BSE corporate-action notices have shown them since: ex-date and record date on the same day. The practical consequence is that guidance written for the T+2 era — the ex-date is the day before the record date — no longer matches how Indian settlement works. And when a settlement holiday falls near the dates, the working-day arithmetic can shift in ways no rule of thumb anticipates, so the dates printed on the exchange notice are the only authority worth trusting.

The last day to buy a share and still get the dividend

To receive an announced dividend, you must buy no later than the trading day before the ex-date. On that final eligible day the share is said to trade cum-dividend — with the dividend attached. Buy on the ex-date itself and the seller keeps the entitlement, because the shares are still theirs when the register is read that evening.

The mirror image surprises people more: you can sell on the ex-date and still receive the dividend. Your sale settles the following working day, so at the close of the record date the shares remain in your demat account and your name remains on the list. The buyer on the other side of that trade knew this when they bought — the price already reflects it, which is the subject of the next section.

Put dates on it as an example: suppose a company fixes a Friday as the record date, and the exchange marks that Friday as the ex-date too. A purchase on Thursday settles on Friday and qualifies. A purchase on Friday settles on Monday and does not. A sale on Friday also settles on Monday, so the seller is still on Friday evening's register. Were Friday a settlement holiday, the notice would carry different dates altogether — which is why the notice, not weekday logic, gets the last word.

One caveat sits at the edges: delivery, not the trade, is what qualifies. In the rare case where a seller fails to deliver and the exchange settles the shortfall through its auction process, the shares can land in the buyer's account after the record date, and the entitlement adjustment then runs through the exchange's close-out mechanics rather than the normal route. It is uncommon, but it is why the register — not the contract note — has the final word.

What happens to the share price on the ex-date?

A share going ex-dividend tends to open lower by roughly the dividend amount, because the buyer is now purchasing a share that no longer carries that cash. Suppose a share trades at ₹100 cum-dividend with a ₹5 dividend announced: on the ex-date, a price near ₹95 represents the same underlying value. Nothing has been lost; the ₹5 has moved from the price into the pocket of whoever held the share through the record date. Normal market forces sit on top of this adjustment, so the actual open can be higher or lower — the point is the mechanism, not a prediction.

For a bonus or a split, the exchange itself restates the reference price on the ex-date. A 1:1 bonus halves the previous close as the share count doubles; a split adjusts the price in the ratio of the change in face value. A portfolio screen showing a 50% fall on a bonus ex-date is displaying that restatement, not a loss — the holder simply has twice the shares at half the price, pending credit of the new ones. In the derivatives segment, exchanges also adjust futures and options contracts for dividends beyond a threshold they set, so large payouts do not distort those positions.

Cum-dividend, ex-dividend and book closure on a corporate-action notice

Exchange notices use a compact vocabulary. Cum means with — a cum-dividend buyer gets the payout. Ex means without. Record date is the register-reading day discussed above. You will also meet book closure: a period, rather than a single day, during which the company's register of members is frozen. Book closure descends from the physical-share era and still appears, typically around annual general meetings, while a single record date is the norm for dividends, bonuses and splits in the demat era. A separate cut-off date governs e-voting eligibility for shareholder meetings — it serves voting, not payouts.

The authoritative places to find these dates are the corporate-action pages of the NSE and BSE, the company's own filing to the exchanges, and the registrar and transfer agent handling the action. Broker apps usually relay the same dates, but a relay can lag. For the terms beyond these, the stock market glossary collects the definitions this series uses.

One record date, many corporate actions

The dividend is only the most familiar tenant of the record date. The same mechanism fixes eligibility for every entitlement a company distributes:

• Dividends — interim dividends are declared by the board and final dividends approved at the AGM; both use a record date to fix who is paid.
• Bonus issues — new shares are credited free in a stated ratio to holders on the record date, and SEBI has tightened the timeline so the credited shares become tradeable within days of it.
• Stock splits — the face value changes and every holding on the register is restated in the same ratio; the split itself neither adds nor removes value.
• Rights issues — holders on the record date receive rights entitlements in their demat accounts, which can be exercised, renounced or allowed to lapse within the offer window.
• Buybacks through the tender route — the record date fixes who may tender shares and in what entitlement ratio.
• Demergers — shares of the resulting company are credited to whoever held the parent on the record date.

In each case the question worth asking is identical: was I on the register at the close of the record date? Everything else — ratios, payment timelines, credit dates — is detail the specific notice will state. A 1:2 bonus, to take an illustrative ratio, credits one new share for every two held on the record date; a holder of an odd lot receives the whole-share entitlement, with any fraction typically settled in cash under the scheme the company announces.

Why buying a share just for its dividend rarely works

The idea suggests itself the first time someone learns these dates: buy cum-dividend, collect the payout, sell on the ex-date. The price adjustment is the first obstacle — the share tends to open lower by about the amount collected, so the dividend is not free money but a transfer from price to cash. Brokerage and statutory charges then apply on both legs of the round trip, and a dividend yield measured against the cum-dividend price overstates what such a trade could capture.

Tax is the second obstacle. Dividends are taxable in the shareholder's hands as ordinary income, and companies deduct tax at source above a threshold. Indian tax law also contains dividend-stripping provisions aimed precisely at purchases made shortly before a record date and sales shortly after, which can disallow part of any capital loss the round trip produces. None of this says anything against holding dividend-paying shares; it says the two-day capture trade is a far narrower proposition than the dates alone suggest.

Mistakes the two dates still cause

1. Buying on the ex-date and expecting the payout — the entitlement stayed with the seller; the last eligible purchase was the previous trading day.
2. Applying the T+2 rule of thumb — articles written before 2023 place the ex-date a day before the record date, which no longer matches Indian settlement.
3. Forgetting settlement holidays — a trading day is not always a settlement day, so the safe check is the exchange notice, not mental arithmetic.
4. Reading a bonus or split adjustment as a crash — the drop on the screen that morning is the exchange's restatement of the price, not a market loss.
5. Selling before the ex-date to lock in the dividend — selling cum-dividend hands the entitlement to the buyer; holding through the ex-date is what secures it.
6. Expecting the money on the ex-date — the record date fixes who is paid, but the cash follows on the payment date the company announces, within the timeline the Companies Act prescribes.

Read together, the two dates describe one clean mechanism: the company photographs its register on the record date, and the ex-date tells the market the last moment a trade can still get into the photograph. Under T+1 the two have merged into a single day on Indian exchanges, which makes the rule simpler than it has ever been — be on the register at the close of that day and the entitlement is yours; buy on it, and it is not.
