Why a share price drops by the dividend on the ex-date

What happens on the ex-dividend date?

The ex-dividend date is the first trading day a share trades without the right to the declared dividend. Per Upstox's learning centre, read on 9 November 2026, the stock exchange adjusts the price on that day to reflect the payout, and the exchanges set and announce the date.

Before the ex-date, a buyer gets the share and the coming dividend together. From the ex-date, a buyer gets the share alone. The share is worth less by the amount of the dividend that no longer comes with it.

Upstox gives the same shape in its own example. A share that closes at ₹500 with a ₹10 dividend may open near ₹490 on the ex-date, subject to market conditions.

Why does the price fall by about the dividend?

A company that pays a dividend hands cash out of the business. After the payment the business holds less, so each share represents a smaller claim. The exchange reflects that on the ex-date by lowering the reference price, rather than waiting for the market to work it out.

Think of a jar of coins that you own. You take ₹24 out and put it in your pocket. The jar is lighter by ₹24 and your pocket is heavier by ₹24. You are exactly as wealthy as before.

Two points keep this honest:

• The price falls by approximately the dividend, not exactly. Upstox notes that market conditions and buying and selling activity also move the price on the day.
• The adjustment is a reference point for the opening. By the close, the share may be above or below it for reasons that have nothing to do with the dividend.

A share that rises on its ex-date rose from a lower starting point.

Worked example: ₹5 lakh in one share

Take a position of 500 shares of a company at ₹1,000 a share, a ₹5 lakh holding. The company declares a dividend of ₹24 a share.

Before the ex-date:

• Share value: 500 × ₹1,000 = ₹5,00,000.
• Dividend due to you: 500 × ₹24 = ₹12,000.

After the ex-date, with the price adjusted to ₹976 and nothing else moving:

• Share value: 500 × ₹976 = ₹4,88,000.
• Dividend received later in cash: ₹12,000.
• Total: ₹4,88,000 + ₹12,000 = ₹5,00,000.

The total is the same ₹5 lakh. The dividend changed the form of the money, from share price to cash, and created nothing.

Why is the dividend still taxed as income?

The tax treatment is where the mechanism costs you something. CalcGuru's summary of the rules for assessment year 2026-27, read on 9 November 2026, says a domestic dividend is taxed in the shareholder's hands. The rate is the shareholder's slab rate, as income from other sources. The price fall, on the other hand, is a loss on paper that you realise only if you sell.

Carry the example forward for a shareholder whose slab rate is 30 percent, before cess:

• Tax on the dividend: 30 percent of ₹12,000 = ₹3,600.
• Cash left after tax: ₹12,000 − ₹3,600 = ₹8,400.
• Value after the ex-date: ₹4,88,000 + ₹8,400 = ₹4,96,400.

The holding is ₹3,600 lighter than it was before the dividend, and that is a tax cost, not a market loss.

The same source says the company deducts TDS at 10 percent for resident shareholders when the dividend in a financial year exceeds ₹10,000. Here the ₹12,000 is above that line, so the company withholds ₹1,200 and credits it against your final tax. You settle the remaining ₹2,400 when you file.

A dividend is the company's decision about where your money sits, and it comes with a tax bill that a price fall does not.

Can you buy just before the ex-date to collect the dividend?

You can, but the arithmetic shows it does not pay. Take the same ₹1,000 share bought on the last day before the ex-date.

• You pay ₹1,000 and receive ₹24 of dividend.
• The price becomes about ₹976 on the ex-date.
• Before tax, you hold ₹976 of share and ₹24 of cash, which is the ₹1,000 you paid.
• After tax at a 30 percent slab, the ₹24 becomes ₹16.80, and you hold ₹992.80 of value for ₹1,000 paid.

You started with ₹1,000 and reached ₹992.80 on the day, before any brokerage or other charges. You paid tax to get your own money back in a different form.

The trade only makes sense if you already wanted to own the share for other reasons. The dividend is a feature of owning it, never a reason that pays for itself.

Which date decides who gets the dividend?

The ex-dividend date decides it, and the record date is the day the company checks its list. Under India's T+1 cycle, a share you buy on a trading day settles into your demat account on the next trading day. Because of that gap, a buy has to be made at least one trading day before the record date to count.

Sources differ on where the ex-date sits. Upstox, read on 9 November 2026, says it is usually one trading day before the record date. Jainam, read the same day, says that since the move to T+1 the ex-date and the record date fall on the same day. Both agree on the rule that matters to you:

• Buy on a trading day before the ex-date, and you are generally entitled to the dividend.
• Buy on the ex-date or later, and you generally are not.
• Sell on the ex-date, and you still generally receive the dividend, because you owned the share before it.

Upstox adds that ex-dates count trading days, not calendar days. By its example, a Monday record date generally means a Friday ex-date when no market holiday sits in between. The exact dates for each company sit in the exchange's corporate actions notice, and the company's own announcement is the source for the amount.

The record date has its own explainer on this site: what the record date decides for a dividend.

What does this mean for a portfolio?

A dividend is cash arriving in your account that used to sit inside a share price. Treat it as a decision point, not as income on top of your holding.

Three habits follow from that:

• Read dividend cash as a small trim of the position that paid it. In the example, the ₹12,000 is 2.4 percent of ₹5 lakh moving from the share into your bank account.
• Decide where the cash goes before it lands. Left idle, it quietly lowers that holding's weight in your allocation, and portfolio rebalancing is the habit that brings the weights back.
• Compare a company's dividend with what it pays out of profit, not with the share price alone. A high dividend yield can reflect a fallen price, which this explainer on dividend yield covers.

A disciplined allocation is set by position size and horizon. A dividend moves money inside that frame and leaves the frame where it was.

Frequently asked questions

Does the share price always fall by the dividend on the ex-date?

The exchange lowers the reference price by about the dividend, so a ₹24 dividend lowers a ₹1,000 share to roughly ₹976. The traded price can end above or below that, because normal buying and selling moves it too.

Do I get the dividend if I buy on the ex-dividend date?

Generally no. A share bought on the ex-date trades without the right to the declared dividend. Buy at least one trading day before the ex-date to be entitled to it, and check the exchange's corporate actions notice for the exact date.

Do I still get the dividend if I sell on the ex-dividend date?

Generally yes. You owned the share before the ex-date, so your entitlement was already set. The share you sold carried the lower, adjusted price, and the dividend arrives as cash on the payment date.

Is a dividend free money?

No. The price falls by about the dividend, so your total value is unchanged before tax. A domestic dividend is then taxed at your slab rate, which is why a ₹12,000 dividend leaves ₹8,400 at a 30 percent slab.

Is TDS deducted on a dividend?

For resident shareholders, the company deducts TDS at 10 percent when the dividend in a financial year exceeds ₹10,000, per CalcGuru's summary read on 9 November 2026. The TDS is credited against your final tax, and you settle any balance when you file.
