AI가 쏘아 올린 코스피 8800 시대, 엔비디아발 '슈퍼 사이클'의 실체 > K-wave Trends

KOSPI's unstoppable run was led by Samsung Electronics, which occupied the 2 trillion won mark in market capitalization for the first time in history. Samsung Electronics, which previously relied on a single product cycle called semiconductors, has now been re-evaluated as a key supplier of artificial intelligence (AI) infrastructure and has re-established itself as the center of the market. Institutional investors rushed to drive the index's rise by pouring in huge amounts of money, which made the market so hot that intraday buying sidecars were frequently activated. However, it is important to note that despite this rapid increase, foreign investors are showing a selling advantage for 17 consecutive trading days to realize profits, and fierce changes of hands are occurring simultaneously within the market.

The epicenter of this market overheating is definitely LG Group stocks, especially LG Electronics. As the rumor of a meeting with NVIDIA CEO Jensen Hwang became concrete, LG Electronics' stock price almost doubled in just a few days, setting a 'double' record and entering the top 10 in KOSPI market capitalization. The stock price, which had stayed in the low 100,000 won range in the past, has attracted explosive interest from the market by combining with future growth engines such as physical AI and robot business. This upward trend goes beyond a simple theme craze and proves that LG Group's strategic transformation from a home appliance-centered company to an AI-based platform company has begun to gain market trust.

The expansion of the global AI ecosystem led by NVIDIA has opened up new opportunities for major domestic companies. 'Computex 2026' held in Taiwan has become a stage where technology leaders from around the world gather, and the AI ​​factory and robot infrastructure strategies discussed here are leading to practical business cooperation among Korean companies. Companies such as SK Hynix and Naver also enjoyed a simultaneous increase in their stock prices as they were incorporated into this global AI value chain. The prevailing assessment is that Korean companies are now ready to play a key role in the ecosystem beyond simple parts suppliers and as partners for global big tech companies such as NVIDIA.

As the market shows signs of overheating, investors' calculations are becoming more complicated. While individual investors seek to realize intraday profits, institutions are repeatedly receiving volume and defending the index. The relatively sluggish performance of the KOSDAQ index means that the 'winner takes all' phenomenon, in which funds are concentrated mainly on large-cap stocks, is deepening. In addition, despite the continued high exchange rate trend with the won-dollar exchange rate exceeding the 1,500 won range, the fact that foreign net selling of large stocks has not subsided suggests that external variables surrounding the fundamentals of the Korean stock market are still formidable.

As seen in the case of LG Electronics, when the value of a specific company rises explosively in a short period of time, it is necessary to have the cool-headedness to check the 'reality' behind it. LG Electronics' OLED TV technology, which has been ranked first globally for 14 consecutive years, and its proprietary smart TV platform, 'WebOS', can be a powerful contact point in the AI ​​era. In other words, the stock price surge should not be interpreted simply as a result of the 'Jensen Huang effect', but as the result of the hardware manufacturing competitiveness and software capabilities that have been steadily accumulated over the years meeting the huge trend of AI and starting to create synergy. Therefore, rather than dismissing the current upward trend as a temporary craze, we should closely observe whether the position that Korean companies occupy in the AI ecosystem is fundamentally changing.
