Calculation of Base Prices
In case where there has been transactions in the previous day:
the closing price of the previous day
In case where there have not been transactions in the previous day:
  • In cases where orders existed in the way that the price was better than the base price of the previous day, the lowest of the selling orders or the highest of the buying orders (special quotation) is used.
  • In cases where orders existed in the way that the price was not better than the base price or orders did not exist, then, the base price of the previous day is used.
Base price in case of stock split and stock consolidation
  • Previous day's closing price × split (consolidation) ratio
    • Amounts less than the tick size are rounded up (same to those cases explained below)
Base prices in case of ex-rights and ex-dividends
Base price of ex-rights shares
  • 〔(cum right price x number of shares before the capital increase) + (issue price × number of shares allotted)〕 / number of shares after the capital increase
    • In case of capital increase with consideration, the issue price is the latest price calculated and disclosed before the ex-right.
    • In case of capital increase without consideration, the issue price is 0.
Base price of ex-dividend shares
  • (cum dividend price x number of shares before the dividend) / number of shares after the dividend
    • Applied only to those issues that disclosed a stock dividend plan
Base price of a mutual fund resuming trading after cash distribution
In case where the distribution amount per share is less than the last price of the second trading day before the book closure date, the base price is calculated by deducting the distribution amount per share from the last price of the second trading day. In case where the distribution amount per share is the same as, or more than, the last price of the second trading day before the book closure date, the base price is determined by receiving orders from the price range of KRW 1 as the minimum, to the last price of the second trading day, as the maximum.
