# The Reality of SK Hynix Stock Dynamics: Fact-Checking Chairman Chey Tae-won’s ‘KRW 4.8B Buy Rumor’ and the Dual Nature of the KRW 35 Trillion Share Buyback

---

## Background

Whenever capital market volatility peaks, investors intensely search for a strong "bottom signal." Particularly for mega-cap stocks like SK Hynix—a cornerstone of the South Korean benchmark KOSPI index and a leader in the global artificial intelligence (AI) semiconductor value chain—every move by top leadership is scrutinized not merely as corporate gossip, but as a potential turning point in institutional and retail trading flows.

Recently, rumors spread rapidly across retail investor communities and brokerage channels claiming that Chey Tae-won, Chairman of SK Group, had directly purchased billions of Korean won worth of SK Hynix shares on the open market. The narrative gained traction with specific claims that this transaction was captured live during a popular YouTube financial broadcast (*Syuka World*). This fueled market optimism that the controlling shareholder was demonstrating management accountability, effectively signaling a definitive price floor.

However, in financial markets clouded by uncertainty, distinguishing unverified rumors from empirical data is paramount. The medium- to long-term trajectory of an equity is driven not by unsubstantiated hearsay, but by corporate fundamentals and officially disclosed supply-and-demand metrics. It is essential to examine the verifiable facts and understand what truly drives SK Hynix's trading dynamics and potential risks today.

## The Core Issue

A rigorous verification of the rumors surrounding Chairman Chey Tae-won’s alleged "KRW 4.8 billion on-market share purchase" and the "YouTube live broadcast capture" through the Financial Supervisory Service’s electronic disclosure system (DART) and major media databases confirms that these claims are **entirely groundless**.

There is no regulatory filing on DART nor any verified news report documenting an open-market equity purchase of SK Hynix by Chairman Chey, nor is there any record of such an event occurring during a live broadcast. The narrative circulating online is simply unverified misinformation that became distorted as it spread through retail investor channels.

Currently, Chairman Chey’s publicly verified issues are confined to personal legal proceedings rather than corporate share acquisitions. These include the submission of an appeal to the Supreme Court regarding the asset division lawsuit stemming from his divorce with Roh Soh-yeong, Director of Art Center Nabi, alongside legal disputes concerning a residential property in Hannam-dong valued at approximately KRW 30 billion.

Ultimately, the anticipated "rebound signal" triggered by a controlling shareholder committing personal capital was an illusion. The psychological price floor that market participants counted on never existed.

## In-Depth Analysis

Looking past the rumors to analyze regulatory filings and equity research data, it becomes clear that the true pillars supporting SK Hynix’s valuation are not individual insider buys, but **unprecedented corporate share repurchase programs** and **structural growth in memory semiconductor fundamentals**.

### 1. Early Conclusion of the KRW 35 Trillion Share Repurchase Program and Shifting Supply-Demand Dynamics
The primary supply-and-demand buffer insulating the domestic equity market from severe downside has been the large-scale share repurchase initiatives executed by semiconductor heavyweights, notably Samsung Electronics and SK Hynix. Totalling roughly KRW 35 trillion across the sector, this massive corporate buying power has served as an institutional firewall, mitigating market volatility and curbing trading curbs (sidecars).

However, current market data suggests that this KRW 35 trillion buyback program is poised to **conclude earlier than expected, around mid-next month**. As corporate price-support measures wind down, the most dominant institutional tailwind that cushioned downside risk will phase out in the short term.

### 2. The Memory Semiconductor Supercycle and Overwhelming Fundamental Strength
Conversely, the underlying operational metrics of the semiconductor industry are exhibiting unprecedented strength. Driven by aggressive AI infrastructure investments from global hyperscalers, the worldwide semiconductor market is projected to reach $1.6 trillion by 2026 and expand toward $2 trillion by 2030.

Samsung Electronics and SK Hynix collectively hold more than half of the global memory market. Industry pricing forecasts indicate that by August 2026, DRAM contract prices could rise approximately 4.4 times year-over-year, while NAND Flash prices are projected to surge as much as ninefold. With supply deficits worsening against soaring demand for high-performance AI memory—particularly High Bandwidth Memory (HBM)—the overall market remains firmly in a "seller's market" regime.

### 3. Counterpoints and Potential Risk Assessment
Despite these robust fundamentals, notable structural risks warrant caution:

* **Liquidity and Sentiment Vacuum:** With the insider buy rumor debunked, an anticipated psychological support level has vanished. If the KRW 35 trillion corporate buyback program finishes early next month, a short-term **liquidity vacuum** could emerge in the absence of a dominant buying entity. This could leave the stock susceptible to amplified volatility in the event of broader macroeconomic shocks.
* **AI CAPEX Moderation Concerns:** Lingering debates persist among global Big Tech firms regarding the pace of AI capital expenditure (CAPEX). Should hyperscalers delay data center buildouts or moderate their investment pacing below market forecasts, the memory sector could face sudden inventory realignments and sharp, near-term price corrections.

## Market Outlook

Looking ahead, the investment environment for SK Hynix will likely be defined by a clear divergence between **near-term liquidity gaps** and **long-term fundamental expansion**.

In the short term, the impending conclusion of the large-scale share buyback program next month represents a major inflection point. As this structural safety net recedes, investors should prepare for heightened daily price volatility driven by macroeconomic data releases and sector-specific headlines. Rather than acting on unconfirmed rumors regarding insider share purchases, a disciplined approach requires closely tracking official regulatory disclosures and liquidity schedules.

Over a medium- to long-term horizon, however, the structural supercycle in memory semiconductors remains the dominant thesis. As AI infrastructure expansion translates into sustained corporate earnings, SK Hynix’s competitive moat and technological leadership in the HBM market remain intact.

Consequently, a balanced strategy involves looking past unverified rumors and viewing short-term supply-and-demand pullbacks—spurred by the conclusion of buyback programs—as potential phased entry opportunities to capitalize on the secular AI memory cycle.
