Hyein Faces Short-Term Overheating Stock Designation Notice on the 11th... Single-Price Trading Possible for 3 Trading Days
Hyein (stock name) has been included in the short-term overheating stock designation notice scheduled for the upcoming 11th. According to the Korea Exchange on the 10th, Hyein will be subject to a short-term overheating stock designation notice in accordance with Article 106-2 of the KRX Market Bus

Hyein (stock name) has been included in the short-term overheating stock designation notice scheduled for the upcoming 11th.
According to the Korea Exchange on the 10th, Hyein will be subject to a short-term overheating stock designation notice in accordance with Article 106-2 of the KRX Market Business Regulations and Article 133-2 of the enforcement detailed rules thereof. Hyein closed the day at 5,930 won, up 20 won (0.34%) from the previous trading day.
However, a 'designation notice' does not immediately mean 'designation as a short-term overheating stock.' The actual designation process proceeds only if, on a specific trading day within 10 trading days after the designation notice date, the following three conditions are simultaneously met, and the closing price on that day is higher than both the closing price of the previous trading day and the closing price of the day before the designation notice.
- ■ Three Main Conditions for Short-Term Overheating Stock Designation
- Stock Price Increase Rate: The day's closing price is at least 130% of the average closing price over the previous 40 trading days
- Trading Turnover Rate: The average daily trading turnover rate over the recent 2 trading days, including the day in question, is at least 600% of the average over the previous 40 trading days
- Stock Price Volatility: The average daily stock price volatility over the recent 2 trading days, including the day in question, is at least 150% of the average daily stock price volatility over the previous 40 trading days
Even if all three conditions are met, there are exceptions. Stocks ranked within the top 100 by market capitalization, integrating both the KOSPI and KOSDAQ markets based on the closing price of the previous trading day, may be excluded from designation. Investment warning stocks or investment risk stocks are also exempt from the short-term overheating stock designation process.
Once the actual designation is confirmed, a single-price trading method in 30-minute intervals will be applied for 3 trading days starting from the next trading day. Investors should monitor Hyein's future stock price trends as well as whether trading volume, turnover rate, and intraday volatility expand.
It should be noted that this disclosure is at the 'designation notice' stage, not an actual 'designation.' If the designation conditions are not met going forward, the stock may not be designated as a short-term overheating stock, so the designation notice should not be interpreted as an actual designation.
