The Korea Exchange announced on the 5th that OneulENM qualifies for designation as an investment caution stock for a single day, November 6, due to trading concentration in a small number of accounts.

According to the disclosure, OneulENM's stock price fluctuation over the past three days was -29.36%. During the same period, the top 10 accounts accounted for 47.76% of sell-side trading participation, of which the largest single account accounted for 8.31%. The investor type of the account with the highest participation was confirmed to be an individual.

The stock was designated zero times for the same reason during the recent 5 and 15 trading days, excluding the day of designation.

Designation for trading concentration in a small number of accounts is applied after comprehensively reviewing price fluctuations and the trading share of certain accounts. The criteria presented in the disclosure include: ▲buy or sell participation rate of 40% or more by the top 10 accounts over the past three days ▲participation on two or more days by five or more of those top accounts ▲an average daily trading volume of 30,000 shares or more on the regular market over the past three days. Here, participation rate refers to the proportion of a relevant account's buy or sell volume out of total regular-market trading volume during the period.

This disclosure concerns a 'caution' designation under the market alert system, which is distinct from a 'warning' designation or a confirmed disclosure of trading suspension.
