|Smart Today=Kim Se-hyung Reporter| As soon as the investment warning designation for SK Hynix was lifted, the stock price is soaring.
As of 8:05 AM on the 29th, SK Hynix is trading at 626,000 won, up 4.51% from the previous trading day in the pre-market.
On the 26th, the Korea Exchange improved the investment warning designation system for long-term rising stocks and unhealthy conditions, accommodating investors' complaints, and was immediately released from the investment warning list as of the 29th.
As Samsung Electronics breaks its record high, it is soaring as the investment warning label that restricted trading has been removed. Samsung Electronics is also showing a strong performance of over 2% on this day. The indiscriminate boom in legacy semiconductors such as DRAM, as well as HBM due to AI investment, is reflected in the stock price.
On this day, Hanwha Aerospace, which was also released from the investment warning designation along with SK Hynix, is showing a slight increase of 0.11%.
The Korea Exchange announced on the 26th that it would implement an improvement plan for the investment warning designation system due to long-term stock price increases starting from the 29th.
The Korea Exchange stated, "Due to the recent overall rise in the stock market, large-cap stocks with a low likelihood of unfair trading have been designated as investment warning stocks under the long-term rising and unhealthy conditions type," and added, "We are changing the relevant designation criteria to enhance the effectiveness of the system."
The investment warning system was introduced at the end of 2023 to prevent unfair trading that evaded existing monitoring by inducing gradual stock price increases through long-term price manipulation using CFDs (Contracts for Difference). This was to prevent the recurrence of the Ra Deok-yeon incident.
The system was based on the stock price increase rate over a specific period, but since the launch of the Lee Jae-myung government, large-cap stocks have frequently been designated as investment warning stocks as the stock market has rallied. In particular, there was a surge of complaints regarding the effectiveness of the system when even SK Hynix was designated as an investment warning stock for this reason.
The Korea Exchange has changed the stock price increase criteria for this type to a stock price increase rate of individual stocks exceeding the market index increase rate by 200% or more. Therefore, while stocks that had previously risen by more than 200% could be designated, in the future, this will apply only if they rise more than 200 percentage points above the KOSPI and KOSDAQ stock price increase rates. In cases where the market index declines, the market index increase rate is considered to be zero (0).
In particular, the top 100 large-cap stocks by combined market capitalization in the KOSPI and KOSDAQ markets will be excluded from the designation of this type of investment warning stocks. As of the closing price on the 26th, the combined market capitalization of the top 100 is 6 trillion won for LG CNS. Therefore, stocks such as Alteogen, EcoPro BM, EcoPro, ABL Bio, Rigakem Bio, Kolon TissueGene, and HLB will be excluded from the designation.
As a result, SK Hynix, which is ranked second in combined market capitalization, and Hanwha Aerospace, ranked 12th, have been released from the investment warning list.
Meanwhile, the Korea Exchange has decided to change the regulations so that stocks released from the investment warning designation for this reason will not be designated again within 60 business days after the release. The previous re-designation period of 30 business days has been doubled.
