- The global AI chip market has recently seen a significant revision in expectations, as concerns about overinvestment in AI infrastructure and the potential peak in computing power demand have intensified, putting pressure on the global semiconductor sector to realize concentrated profits.
- Leading Asian semiconductor companies like Samsung Electronics, SK Hynix, and Kioxia have seen their stock prices fall by about 20% to 30% from their June highs, indicating that the valuation expansion cycle driven by the AI boom is entering a re-evaluation phase.
- The news that social media giant Meta plans to sell part of its AI computing resources has become a key trigger for the shift in market sentiment, prompting global capital to reassess the capital expenditure logic of tech giants in data centers, GPUs, and high-bandwidth memory procurement.
Capital Expenditure Logic Under Market Scrutiny
The core of the market sentiment shift lies in the re-evaluation of the core logic behind tech giants' AI capital expenditures. Meta's plan to sell part of its computing resources has sparked discussions about the sustainability of large tech companies' spending. Over the past two years, expectations for hardware procurement have been extremely high, and current signs of marginal adjustment are amplifying investors' defensive psychology, forcing global funds to withdraw from the semiconductor sector, which previously had excessive valuation premiums, and re-evaluate the actual commercial realization capability of the high-bandwidth memory supply chain.
Concerns Over Imbalance in Computing Power Supply and Demand
Investors' core concern is that the pace of global data center expansion and hardware procurement may have significantly outpaced the actual commercial realization demand downstream. Once the supply of AI computing power begins to exceed actual demand, the narrative supporting the continuous rise of chip stocks may develop cracks. Against this backdrop, any marginal signals of weakening chip demand in the global semiconductor market will elicit highly sensitive reactions, exacerbating the wait-and-see sentiment before the release of high-frequency data.
Korean Capital Market Faces Core Impact
In this round of global sector adjustments, the Korean capital market is facing sensitive and significant risks. Samsung Electronics and SK Hynix, as the largest weighted stocks in the Korea Composite Stock Price Index, are important pillars supporting its economic growth and corporate profits. Over the past six months, the Korean stock market, as a major beneficiary of the AI trend, has been highly dependent on the performance of these two semiconductor giants. As stock prices have significantly retreated from their highs, it has also exposed the Korean capital market's high dependence on a single AI trading logic.
Pressure on Real Economy and Export Stability
Since semiconductors have long been regarded as a core industry and source of fiscal revenue for Korea, if the global AI infrastructure investment boom continues to cool, its impact will deeply extend to the real economy. If the demand and prices for memory chips weaken due to a slowdown in computing power expansion, it will directly harm Korea's macroeconomic stability. In the coming months, whether the AI investment logic can continue to effectively support the global semiconductor upcycle will become the most critical observation indicator for assessing its export performance.
