🚩 Market Sentiment Diagnosis

Today, the A-share market exhibited distinct structural market characteristics. The SSE Composite Index rose 0.96%, and the total market turnover reached a massive 3.205730 Trillion Yuan, indicating extremely active capital participation. However, the advancers/decliners ratio of 2181 / 3224 suggests that most individual stocks declined, with the index’s rise primarily driven by a few heavyweight sectors and stocks. 103 stocks hit their Limit-up, far exceeding the 15 stocks that hit their Limit-down, reflecting explosive localized profit-making opportunities. The blasted bids rate was approximately 24.26% (33 blasted bids / 136 attempts to hit limit-up), which is at a moderate level, indicating some profit-taking pressure in the market, but overall buying support remains decent. Overall, the current market phase can be defined as “volume-driven structural rally, index-led by core assets, with high-level divergence and strong buying support coexisting.” Profit-making effects are extremely concentrated in specific hot sectors, while loss-making effects are prevalent in non-hot sectors and previously overhyped stocks, showing significant polarization in the market.

💰 Core Themes and Capital Flows

Looking at the [Top 20 Stocks by Turnover] list, capital flows are clearly concentrated on two core themes: Semiconductors and AI Computing Power (Optical Modules).

• Hot Sectors:
  • Semiconductors: SMIC (+18.79%), GigaDevice (+10.00%), JCET Group (+10.00%), Cambricon (+9.37%), Tongfu Microelectronics (+9.99%), and several other stocks entered the top twenty by turnover with significant gains, indicating strong capital expectations for the semiconductor industry’s recovery and domestic substitution. Among them, SMIC led with a massive turnover of 37.254 Billion Yuan.
  • AI Computing Power/Optical Modules: E-SUN (+8.61%), InnoLight Technology (+5.30%), TFC Communication (+6.51%), HGTECH (+10.00%), etc., continued the strong performance of AI concepts, with optical modules, as a critical component of AI computing infrastructure, remaining highly sought after.
• High-Conviction Sectors: Leading stocks in the aforementioned semiconductor and AI computing power sectors, due to their market capitalization, industry position, and clear industrial logic, are not only market hotspots but also “high-conviction” allocation directions for institutional capital. The activity of these stocks was the core driver of today’s index gains.
• Market Style: The market style clearly leaned towards a combination of “hard tech theme speculation” and “core tech heavyweight leadership.” This was not merely index-weight support; rather, tech heavyweight stocks with strong industrial logic and growth expectations showed explosive growth driven by capital, creating a positive pull on market sentiment.

🪜 Consecutive Limit-up Ladder and Spatial Play

• Highest Consecutive Limit-up Stock (Space Leader): Sihuan Bio (000518) became today’s space leader with 4 consecutive limit-ups, belonging to the Biopharmaceuticals sector. This stock had a turnover of 1.302 Billion Yuan and a floating market cap of 4.674 Billion Yuan, indicating it is a small-cap speculative stock driven by market sentiment. Its consecutive limit-up height is more a result of emotional gambling, with limited guidance for the overall market direction.
• Consecutive Limit-up Ladder: There were many stocks with 2 or more consecutive limit-ups, including numerous tech-related targets such as TPK Holding, Fenghua Advanced Technology, Bowman Electronics, Guanghua Technology (Components/Electronic Chemicals), Yihua Co., Ltd. (Communication Equipment), etc., confirming the activity of the tech main theme.
• Interpreting Blasted Bids Signals: 33 stocks experienced blasted bids, but it is noteworthy that core tech stocks with high turnover and significant gains like SMIC (688981) and GigaDevice (603986) also appeared in the blasted bids pool. This is not a simple “high-level deceleration” signal. On the contrary, they experienced intense intra-day divergence and capital competition, but ultimately closed with strong gains (SMIC +18.79%, GigaDevice +10.00%), and some even successfully hit the limit-up. This indicates extremely strong buying support, representing sufficient turnover under “healthy divergence,” accumulating momentum for subsequent market movements. However, stocks like Longxing Technology (002442), which closed down -3.21% after a blasted bid, might signal profit-taking by capital and warrant caution.

⚡ Analysis of Key Anomalous Stocks

From the [Key Stock Watchlist], based on turnover and gain percentage, four most representative stocks are selected for analysis:

1. SMIC (sh688981): Up +18.79%, turnover of 37.254 Billion Yuan. As a leading enterprise in China’s semiconductor manufacturing, this massive surge is backed by multiple positive factors: first, the expectation of a global semiconductor cycle bottom reversal; second, increased national strategic support for domestic substitution in the semiconductor industry chain; and third, the surge in AI computing power demand driving upstream chip manufacturing. Strong re-sealing (or closing at a high level) after a high-level blasted bid demonstrates powerful collective capital force.
2. GigaDevice (sh603986): Up +10.00%, turnover of 29.388 Billion Yuan. As a leading enterprise in China’s storage chip and microcontroller (MCU) sectors, it benefits from the recovery of the semiconductor industry’s prosperity and the growing demand for storage and control chips in emerging fields such as AIoT and automotive electronics. Massive turnover and hitting the limit-up reflect high market expectations for its future earnings elasticity.
3. JCET Group (sh600584): Up +10.00%, turnover of 21.049 Billion Yuan. A leader in the semiconductor packaging and testing industry, it is a crucial link in the semiconductor industry chain, connecting chip manufacturing and terminal applications. Its limit-up with high turnover also reflects the overall strength of the semiconductor sector, indicating a potential continuous improvement in downstream packaging and testing orders.
4. HGTECH (sz000988): Up +10.00%, turnover of 17.898 Billion Yuan. The company is competitive in optical communication devices, laser equipment, and other fields, making it a significant beneficiary of AI computing infrastructure construction. With the explosion in demand for global AI large model training, the demand for high-speed optical modules has surged, and HGTECH, directly engaged in this main theme, has become a market favorite.

🧭 Next Day Trading Strategy Recommendations

Current market sentiment is active, but structural differentiation is significant; therefore, operations require clarity and precision.

• Observation Points for Tomorrow:
  • Rebound Potential: Core tech stocks that experienced blasted bids today but still closed strongly with high turnover, such as SMIC and GigaDevice, might present opportunities for a secondary surge or rebound if they open lower or consolidate in the morning session and then rapidly rally with increased volume.
  • Preventative Measures Against Catch-up Declines: Market capital is highly concentrated on the tech main theme. Non-hot sectors or stocks that lacked substantial positive catalysts previously might continue to face catch-up decline pressure given limited incremental capital. Be wary of risks in high-flying, non-main theme stocks.
  • Hotspot Diffusion and Rotation: Observe whether the two core themes of semiconductors and AI optical modules can maintain their strength, and pay attention to any signs of capital diffusion to other tech sub-sectors (e.g., consumer electronics, equipment, materials).
• Operational Tone: The overall operational tone should be “actively participate in core themes, control overall positions, avoid blindly chasing highs, and take profits in non-hot sectors at opportune moments.” In a market where most stocks are falling but the index is rising, stock selection is far more important than market timing. Avoid operating outside of the main themes.
• Key Stock Trading Recommendations:
  • SMIC, GigaDevice, JCET Group, HGTECH, and other strong tech leaders today: If they experience a pullback on reduced volume or a morning washout the next day, long-term investors who are optimistic about their underlying logic may consider establishing positions or continuing to hold. For short-term fluctuations, pay attention to the volume-price relationship: if volume continues to increase and the limit-up holds firm, consider continuing to hold for short-term; if there is volume-driven stagnation or a significant retreat after a blasted bid, consider partial profit-taking.
  • For non-core tech stocks that have seen significant recent gains and experienced blasted bids, it is advisable to observe or partially take profits to mitigate potential pullback risks.
