What it means
When a company declares a dividend, it also announces who will be entitled to receive it. Buyers who purchase the share before the cut-off get the dividend and are said to buy "cum-dividend" (with dividend).
From the ex-dividend date onward, new buyers do not receive it, so the share trades "ex-dividend". The logic is simple.
A share is worth the value of the business, including cash that is about to be paid out. Once the dividend is no longer attached to the share, the value attached to the share drops by about the same amount.
For this reason, the share price typically opens lower on the ex-dividend date by roughly the dividend per share. The fall is not a sign of bad news, as it is simply the payout moving from the company to the existing shareholders.
Other factors, such as market moves, can push the price up or down on the same day, so the match is rarely exact. Investors who want the dividend must buy before the ex-dividend date and keep the shares through it.
Some traders try to buy just before and sell just after, a tactic known as dividend capture. It rarely works as hoped, because the price drop, trading costs and taxes can cancel out the dividend.
Finance teams care about the ex-dividend date for planning. It affects the timing of investor demand, the accounting for dividends declared, and the cash the company needs on the payment date.
Investor relations teams often highlight it in announcements to avoid confusion. The term also helps explain index and fund behaviour.
Because prices drop on the ex-dividend date, price indexes fall slightly, while total return indexes assume the dividend is reinvested. When comparing performance, it is important to know which version of the index is being used.
In practice
Real-world examples.
Example
A utility company declares a quarterly dividend of $0.60 per share. On the ex-dividend date, its share price opens about $0.60 lower, which analysts see as a routine adjustment. Long-term holders ignore the move, because they will receive the cash a few weeks later.
Example
An investor buys 500 shares on the morning of the ex-dividend date and expects a payout. She discovers that the dividend goes to the seller, because she bought too late. She learns to check the calendar on the exchange's website before placing any order that is meant to capture a payout.
Example
A fund manager reviews a portfolio of dividend-paying shares before quarter-end. He checks the ex-dividend dates to estimate how much dividend income the fund will receive in the next month. The estimate feeds into the cash plan, which decides how much will be available to pay out to investors.
Formula
Calculation
Expected ex-dividend opening price = previous closing price - dividend per share
Worked example: a share closes at $50.00 on the day before the ex-dividend date, and the company has declared a dividend of $0.80 per share. An investor owns 1,000 shares.
Step 1: Expected opening price = $50.00 - $0.80 = $49.20.
Step 2: Dividend the investor will receive = 1,000 x $0.80 = $800.
Step 3: Value of shares falls by 1,000 x $0.80 = $800 on paper, from $50,000 to $49,200.
The investor's paper loss on the ex-dividend date is offset by the $800 dividend that is due to be paid. The total wealth is therefore unchanged, before any tax or market movement.Case study
Seen in the real world.
Stonebridge Bank is a fictional listed company that announced a dividend of $1.20 per share. A group of employees who held shares through a savings plan asked whether they should sell before the dividend date to avoid the price drop.
The finance team explained that the drop reflects the cash leaving the company, so selling before the ex-dividend date would mean giving up the dividend while avoiding the drop. The net effect would be roughly neutral, apart from trading costs and tax.
In this illustrative case, the explanation prevented a wave of unnecessary sales. The company now includes a short guide on the ex-dividend date in its annual employee share plan briefing. The guide uses a simple example with 100 shares, so that staff can see the arithmetic for themselves.
Watch out
Common mistakes.
- Believing that the price fall on the ex-dividend date means a loss of value, when it mostly reflects the dividend leaving the share.
- Buying on the ex-dividend date and expecting to receive the dividend, when the purchase had to be made before that date to qualify for the payout.
- Assuming dividend capture is a sure way to profit, without allowing for price drops, costs and taxes.
Questions
People also ask.
What does ex-dividend mean in simple terms?
It means the share is trading without the right to the next dividend, so new buyers will not receive it.
Does the price always fall by exactly the dividend?
No. It tends to fall by about that amount, but other market forces can move the price in either direction on the same day. Taxes can also change how much the price drops in some markets.
Is the ex-dividend date the same as the payment date?
No. The ex-dividend date is the cut-off for buyers, while the payment date is when the money is actually sent to shareholders.
