On the 17th, ChangXin (CXMT), the Chinese version of $SPCX , go all in. Let's see if there's a chance to go all-in at the opening.

Analyzed with WorkBuddy + Hy3:

1. Fundamentals: Explosive Growth + Cyclical Concerns
Financial data (key):
• 2025 full-year revenue RMB 61.8 billion, turning from loss to profit
• 2026 Q1 revenue RMB 50.8 billion (+719% YoY), net profit attributable to parent RMB 24.76 billion (+1,688% YoY)
• 2026 H1 guidance revenue RMB 110-120 billion, net profit attributable to parent RMB 50-57 billion
• Quarterly net profit already exceeded 2025 full-year → indicates the memory super cycle is still accelerating

2. Offering Structure: Scarce Free Float → Amplified Short-Term Volatility
• 6.69B shares issued, representing 10% of post-issuance total share capital
• 50% strategic placement locked up → only 5% of total share capital is freely tradable
• Fundraising of RMB 29.5 billion, the second largest in STAR Market history (after SMIC's RMB 53.2 billion in 2020)
• Estimated lower bound market cap based on issue price ≈ RMB 195 billion
This structure means: on the first day and first 5 days (no price limit), chips are extremely scarce; hot money + passive ETF allocation will scramble aggressively.

3. Valuation Benchmark: All Three Global DRAM Giants Have Exceeded $1 Trillion Market Cap
| Company | Forward PE | PS | Market Cap |
|----------|------------|------|------------|
| Micron | ~7x (peak 11x) | 4.6x | >$1 trillion |
| SK Hynix | ~6.2x | 3.6x | >$1 trillion |
| Samsung DRAM | ~26.64x | — | >$1 trillion |
ChangXin currently holds 7.67% global DRAM share (Q4 2025), SemiAnalysis predicts it may reach 17% by 2028. Technology lagging by 1.5-2 generations, HBM gap. However, A-shares have scarcity premium + domestic substitution narrative.

Institutional valuation range:
• Pessimistic: RMB 1.2-1.5 trillion (DRAM price weakens, cycle downturns)
• Neutral: RMB 2-2.5 trillion (2026 net profit RMB 120-150 billion, 15-20x PE)
• Optimistic: RMB 3-4 trillion (AI super cycle + domestic substitution sentiment fully loaded)
• Extreme rumor: RMB 5 trillion+ (unsustainable, pure sentiment)

4. First 10-Day Trend Forecast (Core Judgment)
Trading rule reminder: No price limit on STAR Market first 5 days (only ±20% circuit breaker), ±20% from D6 onward.
Reference to SMIC 2020: +202% on first day, opening was the high (RMB 95), then continued to fall ~30% over the next 10 days. SMIC raised more funds but had a slightly higher free float ratio; ChangXin has heavier lock-ups → first-day volatility may be more extreme.
2026 STAR Market new stock average first-day gain: 417%+; but ChangXin's size far exceeds ordinary new stocks, cannot simply compare to small-cap gains.

AI judgment (neutral path as base):
D1 (Listing day):
• Issue pricing likely in the RMB 28-35 range (corresponding market cap ≈ RMB 1.95-2.5 trillion)
• Opens high, gain of 40%-80% (market cap surges to RMB 2.2-2.8 trillion)
• Intraday volatility extreme, may trigger circuit breaker
• Emotional peak within 30 minutes of open, then pulls back
D2-D4 (Sentiment speculation period, no price limit):
• D2 may continue to rally, hot money relay, market cap touches RMB 2.5-3.5 trillion
• D3-D4 begins to diverge: some profit-taking, high turnover rate
• D4 or D5 likely sees a stage high
D5 (Last day without limit):
• Key turning point, chips shift from speculators to institutions
• If first-day gain too large (>60%), D5 may already have fallen 15%-25% from peak
D6-D10 (±20% limit in effect, seeking equilibrium):
• Volatility narrows, gradually regressing to RMB 2-2.5 trillion market cap center
• Daily range narrows to 5%-10%
• Around D10, market cap likely falls in the RMB 2.0-2.3 trillion range
• Unless major positive/negative catalysts (DRAM price shock, Apple adoption news, etc.)

Scenario divergence:
| Scenario | D1 Market Cap | D3 Peak | D10 Market Cap | Core Condition |
|----------|---------------|---------|----------------|----------------|
| **Optimistic** | RMB 2.8 trillion | RMB 3.5-3.8 trillion | ~RMB 3 trillion | AI narrative remains euphoric, DRAM contract prices accelerate |
| **Neutral** | RMB 2.2 trillion | RMB 2.5 trillion | ~RMB 2.1 trillion | Normal game, sentiment releases moderately then reverts to rational |
| **Pessimistic** | RMB 1.8 trillion | RMB 1.9 trillion | ~RMB 1.2 trillion | DRAM spot weakens before/after listing, U.S. memory stocks plunge |

5. 5 Key Variables Affecting the Trend
Positive catalysts:
• DDR5/server DRAM contract prices continue to rise (UBS forecasts QoQ +32% in Q3)
• Confirmation of Apple adopting ChangXin DRAM
• Long-term supply agreements with Alibaba Cloud, ByteDance, Xiaomi signed
• Domestic semiconductor policy reinforcement
Negative pressures:
• DRAM spot/contract price weakening (cycle turning point signal)
• Significant pullback in U.S. Micron/SK Hynix (A-share linkage)
• Q3 results decline QoQ (high base effect)
• Selling pressure increases as free float gradually releases

6. One Sentence Conclusion
In the first 10 days after ChangXin Memory Technologies' listing, it will likely follow the typical large-cap IPO path of "opening high → D2-D4 topping → pulling back and converging after D5." The D10 market cap center is about RMB 2.0-2.3 trillion (corresponding stock price ~RMB 28-33). If the AI super cycle narrative hasn't collapsed, RMB 3 trillion is only a sentiment ceiling, not the end; but if DRAM prices turn, RMB 1.5 trillion is not the bottom either.
This is a stock with dual pricing from "cyclical profits + domestic substitution narrative" — short-term trend 70% determined by sentiment, medium-to-long term 100% determined by DRAM prices.
