[Deep Dive] Global Semiconductor Cycle Peak Debate: Profit-taking or Structural Slowdown?

Global Tech Stock Correction and the Reignited Semiconductor Peak Debate

Recently in the US stock market, the Nasdaq index has reversed its intraday course and continued a downward trend, driven by the weakness of large-cap semiconductor companies. Massive profit-taking on major AI-related tech stocks, including NVIDIA, has led to a decline in stock prices, which in turn triggered a concurrent drop in domestic heavyweights Samsung Electronics and SK Hynix. Within online communities and among market participants, a fierce debate is unfolding over whether the current corrective phase represents simple short-term profit-taking or signals a structural peak in the semiconductor industry cycle.

NVIDIA and Broadcom: The Gap Between Expectations and Reality

One of the core factors behind the semiconductor peak debate is the divergence between the earnings guidance of global semiconductor leaders and market expectations.

The Impact of Broadcom's Conservative Guidance

Despite reporting solid quarterly earnings recently, Broadcom's stock price plummeted after presenting somewhat conservative forward guidance that fell short of market forecasts. This indicates that the market's expectations for AI demand growth are extremely elevated. It serves as an example that if companies fail to consistently deliver "outperformance" that exceeds steep consensus estimates, they may face strong selling pressure, even while demonstrating growth.

Emergence of Profit-Taking in NVIDIA

NVIDIA, standing at the forefront of the AI rally, is no exception. Having sustained a record-breaking stock price surge, NVIDIA has recently seen a concentration of massive profit-taking, showing a deceleration in short-term upward momentum. Coinciding with portfolio rebalancing by institutional investors, prevailing analysis suggests this is more indicative of a temporary breather due to valuation burdens rather than an actual decline in AI semiconductor demand.

Domestic Semiconductor Leaders: The Current State of Samsung Electronics and SK Hynix

The weakness in US tech stocks induced record net selling by foreign investors, leading the decline in the KOSPI index. In particular, Samsung Electronics and SK Hynix, core components of the HBM (High Bandwidth Memory) value chain, became the primary targets for offloading.

• SK Hynix: Having established itself as a key partner in global AI infrastructure by leading HBM supply to NVIDIA, it could not avoid the aftermath of the profit-taking volume centered on US tech stocks. However, with the ongoing HBM supply shortage, evaluations indicate that damage to its fundamentals remains limited.
• Samsung Electronics: While seeking to expand market share based on next-generation HBM technology, it suffered stock price weakness as foreign selling concentrated amidst the global tech stock correction. This is also interpreted as reflecting concerns over the slowing pace of unit price increases for legacy memory semiconductors.

Limitations of Traditional Cycle Theory and the New Paradigm

Historically, the memory semiconductor industry exhibited a distinct cycle, typically alternating between two years of boom and two years of bust. However, applying only traditional cycle theory to interpret current market conditions has limitations. Major institutions, including the World Semiconductor Trade Statistics (WSTS), forecast that the structural demand for the global semiconductor market—especially high-performance memory semiconductors essential for AI data center expansion—will not falter in the short term. As long as capital expenditures (CAPEX) on AI infrastructure by Big Tech companies persist, the current stock price correction can be viewed as a healthy consolidation process digesting high valuations, rather than a decline in industry fundamentals.

Future Market Outlook and Implications

The current volatility in the semiconductor sector is the result of uncertainty in the macroeconomic environment combined with high market expectations. Rather than overreacting to short-term stock price fluctuations, investors should approach the market based on objective data such as AI chip demand trends, the continuation of infrastructure investment by major Big Tech firms, and semiconductor inventory levels. The peak debate serves to cool market overheating and provides an opportunity to identify companies with genuine structural growth value through careful selection.
