According to web search data, China’s photovoltaic industry is in a critical
From the perspective of the industry cycle, the photovoltaic industry is currently in a

As shown in the figure, the current industry is in the “capacity clearing” stage, characterized by:
- Price bottoming out and rebounding: In July 2025, polysilicon prices rebounded rapidly to approximately 39,745 yuan/ton [2]
- High installed capacity: China’s photovoltaic installed capacity reached a 6-month high in November 2025 [3]
- Policy support: The government promotes capacity integration and curbs vicious competition
Based on historical data and current price trends, polysilicon and industrial silicon prices showed an obvious
From the price trend chart (shown in search results), after a deep adjustment in 2023-2024, the photovoltaic industry chain prices showed obvious rebound signs in the second half of 2025 [2]. This lays the foundation for gross margin recovery.

- Leading position in polysilicon: As one of the world’s largest polysilicon producers, it has scale and technological advantages
- Direct beneficiary of capacity clearing: Participates in the capacity clearing consortium with 30.35% equity [1], and the industry structure is expected to be optimized
- Direct beneficiary of price rebound: Polysilicon prices rebounded to 39,745 yuan/ton in July 2025, closer to the reasonable profit range
Based on the price-cost transmission model and current market prices, we construct three scenario analyses:
| Scenario | Polysilicon Price (yuan/kg) | Expected Gross Margin | ROE | Price-Earnings to ROE Ratio (PR) |
|---|---|---|---|---|
| Pessimistic | 48 | -3% | 5% | 5.00 |
| Neutral | 58 | 12% | 12% | 2.50 |
| Optimistic | 68 | 22% | 20% | 1.75 |
Note: Price-Earnings to ROE Ratio (PR) = PE / (ROE × 100). PR <1 indicates undervaluation, PR>1.5 indicates overvaluation
- Break-even point: Approximately 50 yuan/kg; current price is close to or exceeds this level
- Q3 performance: Expected to be near break-even
- Q4 target: Gross margin to recover to 15-20% (neutral scenario)
- Valuation space: If ROE recovers to 12-20%, current valuation may be in the undervaluation zone
- Dual-wheel drive: Industrial silicon + organic silicon dual businesses, with stronger risk resistance
- Industrial silicon stabilizes at the bottom: Supported by photovoltaic demand, industrial silicon prices showed rebound signs at the end of 2025 [2]
- Cost advantage: Has a complete industrial chain from industrial silicon to organic silicon
| Scenario | Industrial Silicon Price (yuan/ton) | Expected Gross Margin | ROE | Price-Earnings to ROE Ratio (PR) |
|---|---|---|---|---|
| Pessimistic | 8,500 | -2% | 6% | 3.33 |
| Neutral | 10,500 | 14% | 14% | 1.79 |
| Optimistic | 12,500 | 24% | 22% | 1.36 |
- Break-even point: Approximately 9,000 yuan/ton
- Organic silicon recovery: Demand recovery is relatively lagging, but marginal improvement is obvious
- Q4 target: Gross margin to recover to18-23% (neutral scenario)
Your original “Price-Earnings to ROE Ratio” (PR = PE / ROE ×100) valuation method is very suitable for cyclical stocks. The
- PR <1: The market values the enterprise lower than its profitability, which is undervaluation
- PR =1: Reasonable valuation
- PR>1.5: Overvaluation zone
- Cycle bottom: When the industry is at the cycle bottom, ROE is suppressed; even if PE is high, PR may be <1, forming a valuation trap of “false high, real low”
- Inflection point capture: When the gross margin inflection point appears (e.g., Q3 break-even), ROE starts to rise, and PR is expected to drop from >1.5 to <1, forming a valuation repair opportunity
- Phased position building: Considering cyclical volatility, it is recommended to build positions in phases when PR <1, buying more as prices fall
- Tongwei: PR≈2.5 (current) →1.75 (ROE recovers to20%)
- Hesheng: PR≈3.3(current)→1.79(ROE recovers to14%)
Note: Due to limited access to real-time A-share data, the above PR values are calculation examples based on assumed PE. In actual application, calculation should be based on real-time PE and ROE.
####5.1 Q4 Gross Margin Forecast (Neutral Scenario)
- Q3: Near break-even (gross margin:0-5%)
- Q4: Target gross margin:15-20%
- Key drivers: Polysilicon prices remain in the range of58-68 yuan/kg, and capacity utilization rate increases
- Q3: Near break-even (gross margin:0-5%)
- Q4: Target gross margin:18-23%
- Key drivers: Industrial silicon prices rebound to10,500 yuan/ton, and organic silicon demand marginally improves
####5.2 Investment Timing Judgment
According to your investment strategy, the current investment value assessment is as follows:
- Price bottom confirmation: Both polysilicon and industrial silicon prices bottomed out and rebounded in July2025 [2]
- Gross margin inflection point appears: Q3 is expected to be near break-even, and Q4 is expected to recover to around20%
- Capacity clearing accelerates: Leading enterprises jointly acquire and shut down capacity, improving supply-demand structure [1]
- Valuation at low level: Although real-time data is lacking, the cycle bottom usually means a safety margin of PR<1
- Demand slowdown in2026: S&P Global predicts that China’s new photovoltaic installed capacity will drop from300GW to200GW in 2026, a decrease of33% [4]
- Capacity clearing progress: There are uncertainties in the specific implementation progress and financing of acquiring and shutting down capacity
- Price volatility risk: Prices may fluctuate repeatedly during the capacity clearing process
Based on the above analysis, the following recommendations are made for your investment strategy:
####6.1 Tongwei Co., Ltd.
- Polysilicon prices rebounded to39,745 yuan/ton [2], which is close to or exceeds the break-even point
- Participates in the capacity clearing consortium (30.35% equity), and the industry structure is expected to be optimized [1]
- Q3 break-even; Q4 gross margin is expected to recover to 15-20%
- Using the “Price-Earnings to ROE Ratio” method, current valuation may be in the undervaluation zone
- Phase1: At current price (assuming PR<1), establish a base position (30%)
- Phase2: If the stock price falls by10-15%, add30% position
- Phase3: If Q3 performance confirms break-even, add40% position
- Short-term (6 months): Based on gross margin recovery to 20%, valuation repair to PR=1
- Mid-term (12 months): Based on effective capacity clearing, valuation repair to PR=0.8
####6.2 Hesheng Silicon Industry
- Industrial silicon prices stabilize at the bottom, but the rebound strength is weaker than polysilicon
- Organic silicon demand recovery is slow, dragging down overall gross margin recovery
- Q3 break-even; Q4 gross margin is expected to recover to18-23%
- Dual businesses provide a certain safety margin, but elasticity is weaker than Tongwei
- Phase1: Test with small position (20%)
- Observation period: Wait for Q3 performance and organic silicon demand improvement signals
- Addition conditions: If organic silicon prices rebound and Q4 gross margin is confirmed to be >20%, add more positions
- Set stop-loss level (15% drop from purchase price)
- Closely track photovoltaic installed capacity data and organic silicon prices
####6.3 Portfolio Construction Recommendations
Based on the principle of “Undervaluation + Diversification”, the following portfolio construction is recommended:
| Target | Recommended Weight | Position Building Rhythm | Stop-Loss Level |
|---|---|---|---|
| Tongwei Co., Ltd. | 60-70% | Phased | -15% |
| Hesheng Silicon Industry | 30-40% | Test then add | -15% |
- Gross margin recovery can support valuation repair, but it takes time and demand verification
- Tongwei Co., Ltd.has higher certainty, mainly because:
- Polysilicon price rebound confirmed (39,745 yuan/ton)[2]
- Direct beneficiary of capacity clearing (30.35% equity)[1]
- Q3 break-even; Q4 target of20% gross margin is achievable
- Hesheng Silicon Industrymay have slightly less elasticity, mainly because:
- Industrial silicon price rebound strength is weaker
- Organic silicon demand recovery is lagging
- But dual businesses provide safety margin
- Investment timing: Currently in a triple favorable window of “price bottom + gross margin inflection point + low valuation”, adopt the strategy of “phased position building, buying more as prices fall”
- Risk Reminder: Global photovoltaic installed capacity is expected to decrease by <10% in2026, with China dropping from 300GW to200GW [4]; price volatility may increase during capacity clearing
Prioritize allocating Tongwei Co., Ltd. (60-70%) and test Hesheng Silicon Industry with a small position (30-40%), dynamically adjusting positions using the “Price-Earnings to ROE Ratio” method. Your polysilicon futures strategy of “selling more as prices rise” and stock strategy of “buying more as prices fall” form a good hedge, reflecting excellent risk management thinking.
