Ex-Dividend vs Record Date: When to Buy to Get the Dividend

To receive a dividend, you must complete your purchase two business days before the record date. Korean stocks settle on a T+2 basis, so what matters is not the day you buy but the day settlement finishes and your name appears on the shareholder register. The day before the record date is the ex-dividend date; buy on that day and you miss this dividend. Conversely, if you sell on the ex-dividend date, your right to this dividend is already locked in. In dividend investing, the dividing line is not "when you bought" but "when it settles."

Record date vs ex-dividend date

The record date (baedang-gijunil) is the day that fixes who receives the dividend: whoever sits on the shareholder register that day qualifies. The ex-dividend date (baedang-rakil) is the business day before, the day the right to the dividend "falls off." As KB explains, shares bought from the ex-dividend date onward settle after the record date and are excluded from this round.

The key is T+2 settlement. Even after your buy order executes today, actual ownership registers two business days later. So buying on the record date itself is already too late; your trade must be executed by two business days prior so settlement completes within the record date. KB Capital gives the same "buy two business days ahead" rule.

A dividend goes not to whoever holds the stock on payout day, but to whoever is on the shareholder register on the record date. That is why you watch the settlement day, not the purchase day.

How late can you buy and still get paid?

Assume the record date is December 30. Working backward gives a trading calendar. Ignoring weekends and holidays, the last buy day is two business days before the record date, and the ex-dividend date is the business day immediately before it.

Real calendars contain weekends and holidays, so count "two business days before the record date" in business days. Year-end also brings the market's final closing day, which often pulls the last buy day forward to a few days after Christmas. Check the exact final trading sessions before year-end close if you are buying for the dividend.

Why the price drops on the ex-dividend date

On the ex-dividend date, the price is theoretically adjusted down by the per-share dividend, because the value of the dividend right has left the stock. For example, at a price of 50,000 won and a per-share dividend of 1,000 won, the theoretical ex-dividend base price is 49,000 won. As a yield, that is 1,000 / 50,000 = 2.0%.

The theoretical price is only a starting point; the actual open can fall more or less than the adjustment depending on flows, sector news, and the broader market. That is why buying just before the record date and selling on the ex-dividend date is not automatically profitable. Dividends are subject to a 15.4% dividend withholding tax, so real profit shows up only when after-tax dividend and ex-date loss are weighed together.

Why record dates moved to early next year

Since the Financial Services Commission's 2023 dividend-procedure reform, the dividend calendar has changed. Previously the record date was fixed at December 31 while the dividend amount was decided at the following March shareholder meeting, forcing investors to cross the record date without knowing the payout, the so-called "blind dividend." The reform flipped the order to "confirm the amount first, set the record date later," letting firms fix the dividend at the meeting before setting the date.

According to the Korea Capital Market Institute, 98 KOSPI 200 firms set their 2024 year-end record date around the first-quarter meeting of the following year rather than December 31. Under this method the record date shifts into early next year, so buying blindly at year-end no longer guarantees a dividend. Each stock's disclosed record date must be checked individually.

Before you buy for the dividend

• The target stock's record-date disclosure: fixed at year-end, or moved to early next year under the reform?
• The last buy day, two business days before the record date, counted in business days (weekends, holidays, closing day included)
• The per-share dividend and yield, and the net amount after the 15.4% dividend tax
• The theoretical ex-date adjustment and recent price action around past ex-dividend dates
• For quarterly or semiannual payers, remember the record date recurs several times a year
