📊 Market Core Snapshot Diagnosis

Today, the A-share market displayed significant high-volume activity, with total market turnover reaching CNY 3.24 trillion, indicating strong participation willingness among market funds. The advance-decline ratio of 3215:2133 shows significantly more rising stocks than falling stocks, but it was not an overwhelming broad-based rally, instead exhibiting prominent structural market characteristics. There were 113 Limit-up stocks and only 2 Limit-down stocks, reflecting high bullish sentiment with almost no panic. The failed limit-up rate was approximately 17.5% (24/137), a moderately low level, suggesting that the absorption capacity of limit-up boards is still decent, and while there is high-level trading among funds, most were able to maintain stability. Overall, the current market phase can be defined as: high-volume activity, prominent local hotspots, concentrated profit-making opportunities, but with increasing high-level divergence.

Profit-making opportunities were mainly concentrated in a few popular sectors and leading stocks, such as AI Tech and the Power sector. Loss-making effects, on the other hand, primarily appeared in stocks that were excessively speculated on earlier, lacked sustained logical support, or faced negative impacts, but the overall scope was extremely limited.

💰 Core Main Themes and Capital Flows

Hot Sectors

1. AI/Tech Hardcore Main Theme: From the [Top Twenty Stocks by Turnover] list, tech-related areas such as AI, semiconductors, optical modules, memory chips, and consumer electronics held an absolute dominant position. Foxconn Industrial Internet (AI servers, +10% Limit-up), Zhongji Innolight, Tianjin Fushun Communications, Eoptolink Technology (optical modules), Montage Technology, Cambricon, Biwin Storage Technology, Longsys Electronics (storage), GigaDevice Semiconductor, Luxshare Precision Industry, Han’s Laser Technology, and Pcbh were prominently listed, indicating that capital is highly focused on AI computing infrastructure and its industrial chain. This shows the market’s high recognition of the long-term growth logic of technological innovation and the digital economy, making it the core main theme that capital is currently primarily locked into.
2. Power/Power Grid Equipment: In the [Limit-up Stocks] pool, the Power and Power Grid Equipment sectors performed strikingly, with a large number of limit-up stocks emerging, including Datang Power Generation (6 consecutive Limit-ups), Huadian Liaoning Energy (11 Limit-ups in 20 trading days), Shaoneng Group, Jinkong Electric Power, Hanhe Cable, Baoguang Vacuum Electronic Devices, China Energy Conservation and Environmental Protection Windpower, GCL New Energy Holdings, Mindong Electric Power, and Sifang Automation. The activity of these stocks reflects the market’s strong reaction to policy expectations regarding power reform, new energy transition, and power grid investment, as well as attention to peak summer electricity consumption and the defensive attributes of the power sector. With its low valuation and policy catalysts, this sector has become another “crowded trade” main theme for capital.

Sectors with High Resilience

The tech giants in the top twenty by turnover, as well as large-cap leading stocks in the power and power grid equipment sectors, are currently the sectors offering greater resilience in the market. These sectors either possess a solid performance foundation and industry position or benefit from clear industrial policies, enabling them to accommodate large volumes of capital inflow and outflow.

Market Style Assessment

The current market style is characterized by the coexistence of thematic speculation and large-cap support, with thematic speculation concentrated in the technology and power sectors that possess fundamental support and policy expectations. On one hand, large-cap tech stocks like Foxconn Industrial Internet led the index with limit-up performance, providing a stabilizing effect; on the other hand, the collective activity and consecutive limit-ups in the power sector demonstrated clear thematic-driven characteristics. This “dual-core driven” pattern has provided the market with good activity and structural opportunities.

🪜 Consecutive Limit-Up Hierarchy and Market Reach Dynamics

Highest Consecutive Limit-up and Market Leading Limit-up

Today, the market’s highest consecutive limit-up streak was Datang Power Generation (6 consecutive Limit-ups), belonging to the Power sector. This clearly positions the Power sector as the leader in consecutive limit-up streaks in the current market, reflecting a very high consensus among funds regarding the future prospects of the power industry. Closely following was Huadian Liaoning Energy (11 Limit-ups in 20 trading days), also a power stock, further strengthening the consecutive limit-up intensity and sustainability of the power sector.

The overall structure of the consecutive limit-up ladder is healthy: 4 consecutive limit-ups include Shanghai Jiao Da Onlly, Monalisa Group; 3 consecutive limit-ups include Liren Technology, Yellow River Whirlwind; and a larger number of stocks achieved 2 consecutive limit-ups, such as Tongda Group, Shaoneng Group, Hanhe Cable, Online and Offline, Jinkong Electric Power, Unisplendour Technology, Hefei City Construction, Kewell Technology, Huali Group, demonstrating the breadth and depth of the market’s limit-up sentiment and active sentiment.

Interpretation of Failed Limit-up Stock Signals

Among the 24 stocks in the [Failed Limit-up Stocks] pool, some high-position stocks, such as Dalian Thermal Power (3 Boards in 6 Days) which closed up 1.98% after blowing limit-up, and Zhezong Construction Development (1 Board in 2 Days) which closed up 4.91% after blowing limit-up, indicate that funds are beginning to show divergence at high levels. Profit-taking intentions emerged, but there was no panic selling; rather, there was still capital absorption, categorizing this as benign divergence after high-level deceleration.

It is worth noting that some failed limit-up stocks, such as Boyun New Materials (+8.51%), Huasheng Tiancheng Technology (+9.23%), and DataPort Network Technology (+7.90%), still closed with considerable gains after blowing limit-up, and had higher turnover rates. This suggests that after experiencing intense intraday trading, new buying orders intervened, and the absorption capacity was strong, also indicating benign divergence. These failed limit-ups mostly occurred in previously active AI and digital economy-related concepts, indicating that market attention to these areas remains strong, with only a rhythm adjustment.

🧭 Next Day Trading Strategy Recommendations

Key Observation Points for Tomorrow

1. Can the AI/Tech main theme sustain its momentum: Focus on whether leading stocks in AI servers, optical modules, and semiconductors can maintain strong performance, and whether capital will spread to second-tier stocks. Once high-level leading stocks show high-volume but stagnant growth, it may indicate intensified short-term divergence.
2. Sustainability of the consecutive limit-up ladder in the Power sector: Can Datang Power Generation continue to surge and drive sector sentiment? Pay attention to whether there is a high-to-low rotation within the Power sector, where low-valuation quality stocks or those with catalysts may see compensatory gains.
3. Potential opportunities for high-to-low rotation: Closely monitor stocks in the tech or power industry chains that have fully corrected earlier but whose fundamental logic remains unchanged, and possess potential for rebound. For example, some digital economy and edge computing companies that previously adjusted with the AI trend.
