Summary of Key Points
On the day of its stock market debut in the US, Hynix experienced a stark contrast in market reactions: Its ADR (American Depository Receipt) soared by 13% as overseas investors eagerly purchased shares (with orders exceeding seven times the available supply), while the company's local Korean stock price fell by 10%. There was even an abnormal premium of 15% where the overseas price was higher than the domestic one. This divergence in market sentiment reflects a split opinion regarding Hynix: While overseas markets are optimistic about its AI memory (HBM) business, domestic investors see excessive speculation in its stock price, which has risen by 25 times over the past two years and may contain a bubble. The article analyzes the driving factors behind this surge (including retail investor leverage and the hype around AI), the dual nature of HBM as both a profit generator and a source of risk (due to its reliance on NVIDIA), signs of slowing price increases for HBM, and the issue of storage manufacturers lacking true pricing power, warning that this market trend could be fraught with risks.
Detailed Analysis
The Divergent Reactions on Debut Day: Overseas Investors Buying vs. Domestic Investors Selling
Hynix raised $26.5 billion in its US IPO, one of the largest for a foreign company. Overseas investors were highly enthusiastic, with orders exceeding seven times the supply, and the ADR price was even 15% higher than the local stock price—contrary to the usual trend where domestic shares are cheaper. However, Korean investors sold their shares, causing the local stock price to plummet by 10%.
Why this divergence? Overseas investors are focused on the potential of Hynix's AI memory business, as Hynix is a key supplier of HBM for NVIDIA GPUs, and demand for AI-related products has surged. Domestic investors, on the other hand, are skeptical, noting that the stock price has risen by 25 times in just two years due to retail leverage and a patriotic sentiment of supporting a “national champion” company. This difference in perception reflects varying expectations for the company's future performance.
A 25-fold Increase in Two Years: Performance or Hype?
Hynix's stock price has increased by 25 times since the end of 2022, which is far beyond the typical performance of memory stocks (which usually experience a two-year rise followed by a three-year decline). The main drivers include:
- Retail Investor Leverage: Korean retail investors use margin trading and are driven by a desire to support their national champion company, pushing stock prices to levels that even analysts have difficulty questioning (similar to the 2015 A-share bubble).
- The AI Narrative: HBM is positioned as a crucial component for AI applications; without it, GPUs would lack the necessary data processing power. As NVIDIA's primary supplier of HBM, Hynix has transformed from a cyclical memory manufacturer into a growth star.
- Valuation Bubble: Although earnings have increased, the profit growth has not kept up with the stock price, and the gap between actual performance and expectations reflects market optimism about its future potential.
HBM: A Double-edged Sword
HBM is a high-value component that stacks multiple layers of memory closely around the GPU core to facilitate fast data transfer. While it is essential for AI training due to the massive data demands, this also creates vulnerabilities:
- Dependency on a Single Customer: Hynix's revenue is heavily reliant on NVIDIA, and any shift in NVIDIA's memory strategy could significantly impact its valuation.
- Weak Bargaining Power: NVIDIA has significant influence over HBM prices, limiting Hynix's ability to set its own terms.
Slowing HBM Price Increases: A Sign of a Bubble Bursting?
Initially, there were expectations of continuous price increases for HBM. However, recent data shows that quarterly price growth has slowed, while traditional memory prices have risen more rapidly, suggesting that the narrative of HBM scarcity may no longer hold. A Korean brokerage firm even lowered Hynix's profit forecasts by 8%. This adjustment indicates a shift in market expectations, and previous price premiums may no longer be justified.
The Illusion of AI-Driven Valuations: Storage Manufacturers Lacking True Pricing Power
The market has shifted its valuation focus from GPU performance to HBM bandwidth. While Hynix has benefited from this, it still lacks the technical advantages and pricing power of NVIDIA. Compared to NVIDIA, Hynix falls short in terms of pricing power and gross profit margins. Additionally, the rapid investment in AI technology lags behind the growth of memory revenue, creating a mismatch between spending and revenue generation.
A Final Warning
Retail investors are often the last to realize changes in market trends. Leverage can lead to substantial gains but also severe losses during downturns. Although Hynix's story is compelling, signs of weakness are evident: domestic capital withdrawal, slowing HBM price increases, and dependence on NVIDIA. The “AI memory” narrative may not be as sustainable as it seems. When the market momentum fades, the true risks will become apparent.
In conclusion, this market rally is driven more by hype than solid fundamentals. While Hynix has a promising business, underlying issues such as dependency on a single customer and weak bargaining power pose significant risks. Investors should be cautious and not treat AI-related stocks as perpetually profitable investments.
