Bigtech, a defense industry-related stock, surged more than 20% on the morning of the 22nd, surpassing the 3,750 won level.

With attention on the situation on the Korean Peninsula growing amid remarks by Kim Yo-jong, the sister of North Korean State Affairs Commission Chairman Kim Jong-un, the stock price movements of defense and war-related theme stocks are drawing attention. However, it has not been confirmed whether this rise directly stemmed from her remarks.

■ What Kind of Company Is Bigtech?

Bigtech is a company that produces defense-related products such as electronic warfare systems and military power supply units. It is classified as a defense industry-related stock on the domestic stock market and is regarded as one of the stocks that attracts investor attention when military tensions or security-related issues come to the fore.

■ A Surge in Theme Stocks ≠ Improved Earnings

Defense-related stocks can show sharp price fluctuations during periods of heightened geopolitical tension. This is because the market's reaction to security-related news, rather than actual changes in corporate performance, can influence short-term stock price movements. In the past, defense theme stocks, including Bigtech, have experienced sharp gains and drops in response to changes in the situation surrounding North Korea.

However, a rise in defense theme stock prices does not immediately mean increased orders or improved earnings for the companies concerned. Changes in investment sentiment driven by military tensions need to be examined separately from companies' actual business performance. In phases of growing geopolitical uncertainty, buying may concentrate in certain stocks, but there is also a possibility that stock price volatility will expand if the relevant circumstances change.

■ Key Points to Watch Going Forward

As Kim Yo-jong's remarks draw attention, how changes in the situation surrounding North Korea will affect investment sentiment in defense stocks is also being closely watched. In particular, further remarks related to North Korea and changes in inter-Korean relations, and their impact on domestic defense theme stocks, are key points of interest. However, the direction of individual stock prices may vary depending on investor supply and demand and market conditions, in addition to the geopolitical situation.
