Dividends, ex-date, and subscription rights

Thesis of this lesson: the ex-date is an adjustment, not a bonus

A dividend is not free profit from one day to the next: on the ex-date the share price is adjusted by the dividend amount. If you buy the day before the ex-date, you will receive the dividend, but you paid for it in the share price. What matters is the long-term dividend yield and earnings stability, not buying for the dividend on the last day.

The dividend calendar — and where people go wrong

Intuition says: I buy the day before the ex-date and capture the dividend. At that point intuition is right, and the settlement cycle decides it. The local exchange settles transactions in a T+2 cycle, meaning ownership transfers two business days after the transaction. To be a shareholder on the record date, you must buy the shares no later than two business days before it — which falls exactly on the eve of the ex-date. It is not free, however: the price is then adjusted by the dividend value, as the thesis of this lesson states.

last_day_with_dividend_right ≈ record_date − 2 business days
ex_date = the day after it

The practical consequence: the last day with the right to the dividend is usually the day before the ex-date, but it is set by the current settlement cycle — a market parameter, not a constant. If the cycle changes, that day shifts too, so check the company’s specific schedule.

The rules differ by market, so confirm the settlement cycle and the schedule for the exchange you actually trade on. Companies publish dates and rates in a corporate calendar and in regulatory announcements.

Dividend yield versus payout — two different numbers

Two measures are often mixed, though they answer different questions:

dividend_yield = dividend_per_share / share_price  → how much I receive relative to price
payout_ratio = dividend_per_share / earnings_per_share → what share of profit the company pays out

A high dividend yield alone is not a signal. It is often the result of a falling price rather than a company’s generosity. Before you call a company an income one, check the payout and the payment history of three years — whether the dividend grew, stayed flat, or was cut.

Why the ex-date changes the chart

Technically: if the dividend is $2, on the ex-date the price opens about $2 lower (that is an adjustment, not a loss). For technical analysis, the ex-date can create a gap that is not a real move — which is why:

• you check the corporate calendar before you plan a setup,
• you do not count the loss after the ex-date as a signal,
• with swing trading you account for the adjustment of historical prices (continuous versus adjusted data).

The last point is sometimes a source of a silent error in a backtest: if you tested on unadjusted data, every dividend looks like a sudden drop and the system learns to avoid it. A test on adjusted data gives a different result — and that is the right result.

Subscription rights and pre-issue shares — two things, not one

When new shares are issued, shareholders receive subscription rights — the ability to subscribe for new shares in proportion to their current holdings, usually below the market price. Two related instruments trade:

They are not two words for the same thing: a subscription right is a right, while a pre-issue share is an under-registered share. Nomenclature and listing rules vary between issues — confirm the details in the company’s announcement.

For a swing trader, the relevant fact is dilution: a new issue increases the number of shares, which can lower earnings per share (EPS) and affect valuation. A technical adjustment on the event date is not a signal.

Foreign dividends — a withholding tax layer

With foreign companies, a tax collected in the company’s country of residence (WHT) is added. The mechanics differ from domestic securities:

• The tax is withheld by a foreign intermediary, usually at the rate resulting from a double taxation treaty between your country of residence and that country. Treaty rates are usually lower than statutory rates, but they do not apply automatically — you often have to file a declaration or form with your broker.
• Tax withheld abroad is then settled in your country of residence within the applicable procedures, not by a simple subtraction. There is also a mechanism for refunding over-withheld tax.
• Costs related to the dividend are not deductible — neither domestic nor foreign. The base is the gross payment amount. The details of separating income sources are described in the lesson Taxes on investments.

This is an area where mistakes cost real money and where correct procedures are not obvious. Rules differ by jurisdiction, and this lesson describes the Polish context as an example. If you hold a portfolio of foreign dividend companies, this is the right moment to talk to a tax adviser — not to experiment on a tax return.

When a corporate event says do not trade

1. You do not know the schedule. Entering a company for the dividend requires buying no later than two business days before the record date, that is, on the eve of the ex-date. Without the company’s schedule you do not know whether you capture the payment at all — and even if you do, you gain nothing for free, because the price is adjusted.
2. High dividend yield, high payout, falling price. That is not an opportunity, it is a signal about the company’s condition.
3. An issue with subscription rights is in progress. Until the terms and the number of new shares are established, you do not know the real dilution.
4. A backtest on unadjusted data. Your results are distorted by dividends — fix the data first, then assess the system.

When it matters for a trader

• The corporate calendar is an element of the weekly plan: ex-dates and issues are announced in advance.
• Do not buy for the dividend without analysing yield, payout, and stability — total return matters, not a single payment.
• Watch subscription rights in thin companies — they can distort liquidity and spread.
• A dividend also matters for taxes — as income taxed on the gross amount, with rules that depend on your jurisdiction.

Measurable exercise

Choose a company that pays a dividend. Record: the record date, the ex-date, the amount per share, the dividend yield, the payout, and the payment history of three years. Then calculate the total return from two scenarios on the same data: (a) buying on the last day with the dividend right and holding for a year, (b) buying on the ex-date and holding for a year. Record the difference in per cent. This exercise ends the discussion about capturing the dividend with a number rather than an opinion.

Common questions

Is it worth buying shares before the ex-date to receive the dividend?

Usually not — you receive the dividend, but the price is adjusted by it. The purchase on the eve of the ex-date does give the right to the payment: under a T+2 cycle it settles exactly on the record date. There is no free profit, because on the ex-date the price falls by the dividend amount. Income quality is assessed through dividend yield and payment stability, not by capturing one payment.

How does dividend yield differ from payout?

Dividend yield is the dividend divided by the price — it says how much you receive relative to the price. Payout is the dividend divided by earnings per share — it says what share of profit the company pays out. A high yield with a 90% payout is sometimes a warning, not an opportunity.

What are subscription rights and how do they differ from pre-issue shares?

Subscription rights are the right to subscribe for new shares in an issue — they can be exercised or sold. Pre-issue shares are shares from the new issue before registration in the depository. They are two different instruments; confirm the details in the announcement for the specific issue.

Where do I check corporate dates?

In the exchange's corporate calendar and in the company's regulatory announcements. The dates are announced in advance — that is part of the plan, not a surprise.
