Market Overview of AI Concept Stocks in Late October

In late October 2026, the AI concept stock market exhibited significant structural differentiation. With continuous breakthroughs in artificial intelligence technology and deepening commercialization, the market's valuation logic for AI concept stocks is undergoing profound changes. According to the latest data, the entire AI sector showed an upward trend with fluctuations in late October, but internal structural differentiation intensified. The two main lines of computing power and applications performed distinctly differently, market hotspot rotation accelerated, and capital flows formed a new pattern.

Overall Market Performance and Sector Differentiation

As of October 22, the overall AI concept stock index rose by approximately 3.2% compared to the end of last month, outperforming the broader market index by 1.5 percentage points. However, performance within sectors varied significantly: the computing power sector performed strongly, with related indices rising 5.8%; while the application sector was relatively weak, rising only 1.2%. This divergence trend reflects changing valuation logic for different segments of the AI industry chain.

Looking at sub-sectors, chip design, server manufacturing, and cloud services within the computing power sector performed exceptionally well, with many leading stocks reaching recent highs; while sub-sectors such as intelligent healthcare, smart education, and smart manufacturing in the application sector performed relatively flat, with some individual stocks even experiencing corrections. This differentiation indicates that the market is reassessing the commercial value and growth potential of various segments of the AI industry chain.

Intensifying Divergence in Computing Power and Application Dual Tracks

Computing Power Sector: Technological Breakthroughs and Demand Resonance

The computing power sector performed impressively in late October, driven by multiple factors. First, AI chip technology continues to break through, with significant performance improvements in new-generation GPUs, TPUs and other specialized chips, while costs continue to decline, providing hardware foundation for large-scale deployment of AI applications. Second, demand for large model training and inference has surged, showing explosive growth in demand for computing resources. Third, policy support continues to strengthen, with local governments successively introducing measures to support the construction of data centers and computing power centers, providing strong support for the development of the computing power industry.

Specifically, leading stocks in the computing power sector performed particularly prominently. Taking an AI chip design company as an example, its latest third-generation AI chip offers 3 times the performance of the previous generation with 40% lower power consumption. After its release, the stock price hit the limit-up for three consecutive trading days, with market value breaking historical highs. Another cloud service provider, leveraging its AI computing power service platform, achieved 85% year-on-year revenue growth in the third quarter, with its stock price reaching a new high for the year.

Application Sector: Commercialization Challenges and Opportunities Coexist

Compared to the strong performance of the computing power sector, the application sector performed relatively weak overall in late October. This mainly reflects the challenges faced in commercializing AI applications. Although AI technology has broad application prospects in various fields, the transformation from technology to product still faces numerous obstacles, including data quality, algorithm optimization, user experience, and business models.

However, the application sector is not entirely negative. Some sub-sectors such as AI+ healthcare, AI+ finance, and AI+ education show strong growth potential. For example, an AI medical imaging analysis company recently received bulk purchase orders from Class A tertiary hospitals, with third-quarter revenue growth exceeding 60%, and its stock performance outperforming the sector average. This indicates that within the application sector, sub-segments that can truly solve industry pain points and have clear business models still receive capital favor.

New Logic in Institutional Capital Flows

New Characteristics in Capital Allocation

Analysis of capital flows in AI concept stocks in late October reveals changing logic in institutional capital allocation. First, capital is increasingly focusing on core segments of the industry chain, such as upstream areas like chip design and computing power services, while relatively reducing attention to application layers. Second, capital prefers leading companies with technical barriers and scale effects, rather than pure concept speculation. Third, capital is beginning to focus on the actual implementation of AI technology, giving higher valuations to companies with faster commercialization processes.

Data shows that in late October, institutional net inflows in the computing power sector reached 23 billion yuan, while net inflows in the application sector were only 8.5 billion yuan, showing significant differences in capital flows. Additionally, northbound capital showed a similar trend, significantly increasing holdings of leading computing power sector stocks while reducing positions in some application concept stocks.

Logic Behind Institutional Portfolio Adjustments

The institutional capital adjustments reflect their deep understanding of AI industry development. On one hand, as AI technology continues to mature, computing power as infrastructure is becoming increasingly important, with higher certainty and growth potential. On the other hand, the commercialization process of AI applications is still in its early stages, facing many uncertainties, making institutional capital more cautious.

Notably, some institutions with long-term optimism about AI industry development are adopting a "core + satellite" investment strategy, focusing on core segments like computing power while moderately allocating to high-growth potential application areas to balance risk and return. This strategy both grasps the main development lines of the AI industry and maintains attention to emerging application opportunities.

Market Hotspot Rotation and Investment Opportunities

Characteristics of Hotspot Rotation in Late October

In late October, hotspot rotation in AI concept stocks accelerated, showing "short, flat, fast" characteristics. First, the frequency of hotspot switching increased, with each hotspot lasting an average of 3-5 trading days, 1-2 days shorter than the previous month. Second, the coverage of hotspots expanded, extending from traditional AI chips and cloud computing to AI+ vertical fields, with emerging areas like AI+ agriculture and AI+ environmental protection beginning to attract attention. Third, hotspot speculation became more rational, with capital focusing more on companies' actual performance and growth potential rather than pure concept speculation.

Specifically, in early October, AI chip concepts led the gains; in mid-October, computing power service concepts took over; in late October, application areas like AI+ healthcare and AI+ education became active. This hotspot rotation reflects the market's deepening understanding of different segments of the AI industry chain, providing diversified investment opportunities for investors.

Analysis of Investment Opportunities in Late October

Based on the market performance and capital flows of AI concept stocks in late October, we believe the following areas deserve attention: first, computing power infrastructure, especially leading companies with technological advantages and scale effects; second, AI chip design companies capable of providing high-performance, low-power chips; third, AI+ vertical fields that have achieved commercialization and have clear business models; fourth, AI technology service providers capable of offering one-stop AI solutions.

For investors with different risk preferences, we recommend differentiated investment strategies: investors with higher risk tolerance can focus on growth companies in the computing power sector; investors with average risk tolerance can focus on leading companies in the computing power sector and companies in the application sector that have achieved commercialization; conservative investors can focus on AI-related leading companies with stable cash flows and dividend policies.

Future Outlook and Investment Strategy

Future Development Trends of AI Concept Stocks

Looking ahead, AI concept stocks are expected to continue showing structural differentiation characteristics. On one hand, with continuous breakthroughs in AI technology and acceleration of commercialization, computing power as infrastructure will become even more important, with related leading companies expected to receive continuous attention and capital support. On the other hand, the AI application field will gradually differentiate, with sub-segments that can truly solve industry pain points and have clear business models standing out and gaining market recognition.

Additionally, the impact of policy factors on AI concept stocks will continue. With increasing national support for the AI industry, the introduction and implementation of related policies will provide strong support for AI concept stocks. Particularly, policy measures in areas such as computing power infrastructure construction, AI talent cultivation, and industrial application promotion will have a positive impact on related concept stocks.

Investment Strategy Recommendations

Based on the analysis of AI concept stock market performance in late October and judgment of future development trends, we propose the following investment strategy recommendations: first, adopt a "core + satellite" investment strategy, focusing on core segments like computing power while moderately allocating to application areas; second, focus on leading companies in various segments of the industry chain, grasping the main development lines of the industry; third, pay attention to the actual implementation of AI technology, selecting companies with faster commercialization processes; fourth, monitor policy trends, seizing investment opportunities brought by policy dividends.

At the same time, investors need to pay attention to risk control. AI concept stocks are highly volatile, and investors should reasonably allocate positions according to their own risk tolerance, avoiding blindly chasing highs. Additionally, the AI industry develops rapidly, and investors need to continuously follow the latest technological progress and commercialization developments, adjusting investment strategies in a timely manner.
