During trading on the 30th, 11 out of 15 nuclear decommissioning and maintenance related stocks in the domestic market showed a combined upward trend. No individual disclosures or specific catalysts were identified on the day; however, this movement is analyzed as an extension of the ongoing expansion trend in the nuclear decommissioning and maintenance industry this year.

Meanwhile, the domestic stock market has been influenced by U.S. benchmark interest rate trends this year and volatility in oil prices and exchange rates caused by the U.S.-Iran war that has continued since February. In fact, following the outbreak of the war, approximately 69% of KOSPI and KOSDAQ listed stocks declined at one point, marking a period of heightened overall market volatility. However, this is merely a macroeconomic variable and not a specific catalyst targeting only the nuclear decommissioning and maintenance theme.

[Stock-by-Stock Price Movements and Trading Volume Status]

The stock with the highest gain on the day was KEPCO KPS, recording a 4.50% increase. Large-cap stocks such as Doosan Enerbility (0.82%) and Hyundai E&C (1.06%) also showed modest gains. Mid- and small-cap equipment and component stocks recorded higher gains than large-cap stocks, with Wonil T&I (4.68%), Vitzrotech (3.89%), Daechang Solution (3.66%), Hantech (1.60%), Woojin (1.49%), and Orbitech (1.37%) being representative examples.

However, no individual catalysts were identified to directly explain the rise in these stocks. In particular, some stocks such as Wonil T&I (trading volume: 5,135 shares) and BHI (trading volume: 137,009 shares) had relatively low trading volumes, so caution is necessary when investing.

On the other hand, four stocks declined: KEPCO E&C (-0.85%), Woori Technology (-2.10%), S&L (-1.26%), and WithTech (-1.90%). S&L (trading volume: 3,267 shares) and WithTech (trading volume: 7,978 shares) had very low trading volumes, meaning the actual trading scale was negligible relative to the decline. The stock with the largest drop was KNR Systems, which fell to 13,110 won, down 1,920 won (-12.77%) from the previous day.

[Three Key Variables to Watch Going Forward]

The main variables that will determine the future direction of nuclear decommissioning and maintenance related stocks can be summarized into the following three points: 1. Whether KEPCO KPS will succeed in winning the maintenance order for the Czech Dukovany project in the second half of the year 2. The timing of progress in the contract phase for Hyundai E&C, which is participating in a U.S. nuclear power project 3. The actual implementation of the decommissioning of Kori Unit 1 and the plan to remove spent nuclear fuel by 2031
