Major securities firms' stock prices are showing a downward trend early in the trading session on the 28th, coinciding with the ex-dividend date.

NH Investment & Securities shares are trading at 14,010 won, down 780 won (5.27%) from the previous day as of 9:33 a.m. In the same period, Mirae Asset Securities' stock price also registered a decline of 330 won (3.32%) to 9,620 won.
In addition, Yuanta Securities Korea and Yuanta Securities Korea preferred shares are also on a downward trend on the ex-dividend date.
On the ex-dividend date, major securities firms are showing weakness in their stock prices. A listed company pays dividends to shareholders who hold shares by a specific date, referred to as the 'dividend record date.'
To receive dividends, shares must be purchased two business days before the dividend record date, and the day right after that, when the right to receive dividends ceases, is called the 'ex-dividend date.'
Major securities firms set the dividend record date for this month on the 31st, making yesterday (the 27th) the dividend record date. Therefore, beginning today, anyone who purchases shares will no longer be eligible for dividends, resulting in a decline in stock prices on this ex-dividend date.
