[Edaily Reporter Kim Kyung-eun ] As the “patriotic theme stock” craze spreads across the domestic stock market, buying interest is shifting toward related stocks. However, experts caution that investors should exercise caution, as some stocks have begun to decline as investor interest wanes.

According to MP Doctor on the 20th, as of 9:18 a.m. that day, JOOYONTECH(044380)surged 312 won (30.00%) from the previous trading day to 1,352 won, hitting the daily price limit.

At the same time, SONOKONG CO., LTD.(066910)was trading at 2,970 won, up 685 won (29.98%) from the previous close. At the same time, HansungEnterprise(003680) was also trading at 16,000 won, up 1,400 won (9.64%).

These stocks have ridden the wave of the “patriotic theme stock” craze after being highlighted in online communities as domestic brands and long-standing companies. This is driven by a growing investment fervor to protect “patriotic companies” facing delisting concerns, as the market capitalization threshold for KOSPI-listed companies has been raised to 30 billion won.

However, warnings are also emerging that investors should exercise caution, as the surge in short-term buying has occurred without any improvement in the companies’ fundamentals. This is because the stocks could plummet even without any negative news if market interest shifts to other themes or if profit-taking selling pressure emerges.

In fact, some stocks that had been riding a wave of gains as “patriotic” theme stocks until recently plummeted today. As of this writing, GOOD PEOPLE CO., LTD.(033340)is trading at 448 won, down 82 won (15.47%) from the previous trading day, while Enex(011090)is trading at 2,370 won, down 385 won (13.97%) from the previous close. HYUNGJI ELITE(093240)(-22.59%), #HYUNGJI Innovation and Creative Company Limited (-19.02%), and Castelbajac Co., Ltd.(308100)(-15.55%) also plummeted.
