SK Hynix's rise to No. 1 in market capitalization is evidence that the market no longer places high value on the dominance of a specific industry and capital efficiency rather than on the size of the company or business diversification. While Samsung Electronics has enjoyed a stable premium as a comprehensive semiconductor company encompassing mobile, home appliances, and foundry, SK Hynix has proven its overwhelming growth potential through high-bandwidth memory (HBM), an essential commodity in the AI ​​era. In particular, the phenomenon of global institutional funds flocking to SK Hynix in hopes of expanding contact with the U.S. stock market suggests that the supply and demand leadership in the market has already completely shifted to the high-profit AI memory sector. Rather than viewing this reversal as a temporary change in weight class, experts are analyzing it as the result of a shift in the market's standard of corporate value from 'stable platform' to 'core of the AI ​​value chain'.

On the other hand, market enthusiasm is taking on a speculative aspect, raising concerns. Following the 2x leveraged ETF, even 3x leveraged products have appeared in overseas stock markets, stimulating investors' 'high risk, high return' mentality. In this ultra-high-risk investment environment, a sharp drop in stock prices immediately led to forced liquidation counter-selling and became a boomerang that threatened the accounts of individual investors. As the number of people investing with debt increases, with margin transaction loan balances approaching an all-time high, even small volatility in the market is becoming a detonator that increases systemic risk in the entire stock market. As speculative sentiment, which bets on short-term stock price fluctuations rather than evaluating the value of assets based on fundamentals, is strengthening, there are growing criticisms that a sound investment culture may be damaged.

NVIDIA CEO Jensen Huang's statement during his visit to Korea that "falling stock prices are an opportunity to buy cheaply" caused a huge stir in the market. He preached long-term optimism, emphasizing that the construction of AI infrastructure has just begun in its early stages, but some are raising their voices of criticism, calling this a careless statement that will encourage overheating of the market. In particular, foreign financial experts warn that the Korean and Taiwanese stock markets have entered an overheated phase thanks to the benefits of semiconductors, and point out that a CEO with enormous influence who only emphasizes optimism without specific performance figures can send a dangerous signal to individual investors. Until expectations about AI are confirmed by actual increases in chip orders and profits, the cautious view that it is difficult to dismiss market volatility as simply an opportunity to buy at low prices is gaining ground.

The listing of very large companies such as SpaceX and the resulting valuation controversy also demonstrate the challenges currently facing the market. The market has placed an astronomical value of $2 trillion on Space There is also a high-point theory raised that SK Hynix is ​​also dependent on the super cycle of a specific industry, as was the case with HMM during the past pandemic. However, experts are wary of mechanical comparisons, saying that SK Hynix has a solid performance foundation that is different from the overhang issues at the time. In the end, the value of a company will be determined not only by a fancy blueprint for the future, but also by actual management performance that proves expectations with realistic profits.
