Article 2     The expression "an irregularity in the cumulative percentage of increase or decrease in the closing price of a security during the most recent period" as used in Article 4, paragraph 1, subparagraph 1 of the Directions shall mean that any of the following occurs to a particular security on a given day:
  1. The cumulative percentage of increase or decrease in the closing price of that security for the most recent 6 business days (inclusive of the given day) is greater than 32 percent, while differing with the average values for both the market as a whole and for same-sector securities, as calculated in accordance with this paragraph, by 20 percent or more.
  2. The cumulative percentage of increase or decrease in the closing price of that security for the most recent 6 business days (inclusive of the given day) is greater than 25 percent, while differing with the average values for both the market as a whole and for same-sector securities, as calculated in accordance with this paragraph, by 20 percent or more, and the difference between the closing prices of that security for the initial and final days of the most recent 6 business days (inclusive of the given day) is NT$50 or more.
    Exceptions to the preceding paragraph are as follows:
  1. The percentages of increase or decrease in the closing prices of newly-listed common stocks for which there is a period of no restrictions on price fluctuations shall not be included in the calculations of numerical standards under this paragraph.
  2. When non trade-related factors (such as ex-rights or ex-dividend factors) have caused fluctuations in the price of a security or an index during the period for which standards under the preceding paragraph are calculated, those factors shall be excluded when calculating the percentage of increase or decrease in the closing price or the closing index.
  3. The standards of the preceding paragraph shall not apply when the closing price of a security (excluding call (put) warrants) is less than NT$5.
  4. The provisions of the preceding paragraph regarding same-sector securities shall not apply when there are fewer than five securities in a given sector.

  1. The cumulative total turnover rate for the most recent 6 business days (inclusive of the given day) exceeds 50 percent, while there is a difference of 40 percent or more between the cumulative total turnover rate and the average value for the market as a whole, as calculated in accordance with this subparagraph.
  2. The intraday turnover rate is 10 percent or more, while there is a difference of 5 percent or more between the turnover rate and the average value for the market as a whole, as calculated in accordance with this subparagraph.
    Exceptions to the preceding paragraph are as follows:
  1. The daily turnover rate of newly-listed common stocks for which there is a period of no restrictions on price fluctuations shall not be included in the calculations for the standards under the preceding paragraph.
