Summary of Key Points
This week has been dubbed the "Super Storage Week": ChangXin Technology (a leading domestic DRAM manufacturer) went public on the A-share market, where its stock price experienced a rollercoaster ride on its first day; SK Hynix and Samsung Electronics released their second-quarter financial reports, providing crucial data on profits and inventory levels. The market fluctuations this week mark a significant shift in China's storage industry from being a "follower of global trends" to a "factor that cannot be ignored in global market valuations." The A-share market has priced ChangXin's scarcity higher, while the U.S. stock market has re-evaluated its potential competition due to ChangXin's entry. Global capital is now competing over the "future value of Chinese storage."
I. First-Day Stock Price Volatility: Some Realize Profits, Others Bet on the Future
On the day of ChangXin Technology's listing, the stock price dropped from 49.5 yuan to 38.11 yuan, then soared to 55 yuan, and finally settled around 49 yuan, with a high turnover rate of 66.4% (indicating that more than two-thirds of the circulating shares changed hands).
- Why the drop? Original shareholders (such as those who won the lottery to buy shares or early investors) were eager to sell. They had purchased the shares at a low cost, and their paper profits had multiplied several times after the listing, so they wanted to realize their gains quickly. In just 10 minutes, small and medium-sized orders (from individual retail investors and smaller institutions) sold a total of 37.8 billion yuan, overwhelming the buying pressure.
- Why the rebound? Large funds (institutions and major investors) stepped in to buy shares. They are optimistic about the future of Chinese DRAM, as ChangXin is the only domestic company capable of mass-producing DRAM, which is a critical component for smartphones, computers, and AI devices. When the price reached around 38 yuan, the purchasing power of these large investors exceeded the selling pressure, causing the stock price to rebound rapidly.
- The significance of this price movement: It does not reflect a valuation calculated by models but represents a clash between two attitudes: one is the desire to make quick profits and sell, while the other is the willingness to invest for the long term.
II. The 49-Yuan Valuation: Buying the "Present" or the "Future"?
ChangXin Technology's market value on its first day was approximately 3.28 trillion yuan, 2.1 trillion yuan higher than the "fundamental center" (the reasonable value based on current profits and production capacity). This excess amount is referred to as "option value"—it's like buying a lottery ticket, paying now in hopes of winning a large prize in the future.
- What is being bought at 49 yuan? It's not ChangXin's current profits (the company has not yet achieved significant profitability) nor the current boom in the DRAM market (although DRAM prices are rising). Instead, it's the potential of Chinese storage over the next decade—whether they can develop more advanced HBM (high-speed memory for AI), improve chip yield rates, and capture a larger share of the global market.
- The role of Korean companies' financial reports: Reports from Samsung and SK Hynix provide insights into how much money can be made in the AI storage sector (HBM) and whether inventory levels are starting to decrease (indicating improving demand). These data help investors determine whether ChangXin's "option value" of 2.1 trillion yuan is justified.
III. A Shift in the Global Storage Landscape: China Becomes a Fourth Player
Previously, the global DRAM market was dominated by Samsung, SK Hynix, and Micron. Now, ChangXin Technology has become the fourth major manufacturer, representing a significant change.
- For China: This is a crucial step towards domestic substitution (reducing reliance on imported memory).
- For the global market: It means increased supply. The cycle of this industry follows a pattern of "shortage today → expansion by all players → oversupply tomorrow." With AI demand driving up DRAM prices, manufacturers are looking to expand production. ChangXin's entry could complicate future supply; if expansion is too rapid, it may trigger another price drop.
- Market concerns: U.S. storage stocks (such as Micron) fell on the day of ChangXin's listing, reflecting concerns that ChangXin could steal market share or exacerbate oversupply.
IV. Disagreements Between Domestic and International Markets: A-share Market Prices Rise, while U.S. Stocks Fall
On July 27th, the A-share semiconductor index rose by 4.21%, with ChangXin Technology's stock price driven up by its scarcity. In contrast, the Philadelphia Semiconductor Index in the U.S. fell from a 1.1% increase to a 2.23% decrease, with storage stocks generally declining.
- The A-share market's perspective: ChangXin is considered the "first true world-class technology company" on the A-share market, with strong scarcity. Private equity and institutional investors are optimistic about its long-term value (Nomura has set a target price of 112 yuan, and Goldman Sachs believes its HBM development could exceed expectations).
- The U.S. market's perspective: Overseas investors are more concerned about the competitive threat: ChangXin's expansion, combined with breakthroughs in domestic lithography technology (such as immersion DUV), could lead to rapid catch-up by Chinese storage companies and impact the profits of Samsung and Micron.
- At its core: The A-share market is buying into the "growth story of Chinese storage," while the U.S. market is selling off potential risks related to future competition.
V. ChangXin's Challenges: From "Paper Valuations" to "Real Performance"
ChangXin raised 57.9 billion yuan through its listing (with a potential maximum of 66.6 billion yuan due to the green shoe option mechanism). However, how this money will be spent and whether it can translate into real profits in the future is the biggest test.
- Challenges to overcome:
1. Technical challenges: Can ChangXin improve HBM yield rates and advance its manufacturing processes?
2. Cyclical challenges: How can the company remain profitable despite fluctuations in DRAM prices?
3. Competitive challenges: Samsung and SK Hynix are already investing in advanced products like HBM4; can ChangXin keep up?
4. Profitability challenges: The current valuation represents an "advance payment for the future"; will these investments turn into actual profits in the next few years?
Zhu Yiming, the chairman of ChangXin Technology, holds a paper wealth of 78 billion yuan. Whether this value will be realized depends on whether ChangXin can overcome these challenges. After all, the market will not continue to support just "stories"; performance will ultimately speak for itself.
In Conclusion
ChangXin Technology's listing is not just about one company but a signal that China's storage industry is moving from following global trends to competing on equal terms. It forces the global market to reevaluate what Chinese storage can achieve.
