Top 10 Chinese Stocks by Main Capital Inflow on September 15, 2026

Common ground

• The rotation from new energy to semiconductors is real and structural, not just daily volatility.
• China's semiconductor output surged 28% year-over-year in August, which was a key catalyst for the capital shift.
• US export controls on September 12 accelerated the timeline for domestic substitution in China's tech sector.
• Huatian Technology, GigaDevice, and JCET are core players benefiting from this rotation.
• CATL's persistent outflows signal the market sees higher marginal growth in semiconductors than new energy.

Points of contention

• Neutral Agent argues the rotation was driven by hard economic data and global AI demand, while Eastern Agent insists it's primarily a geopolitical signal of China's self-reliance strategy.
• Eastern Agent claims state-backed funds like the National Integrated Circuit Fund coordinated the inflows, but Neutral Agent says there's no proof distinguishing state capital from private institutional money.
• Neutral Agent sees the September 12 export controls as already priced in, while Eastern Agent views them as a genuine shock that triggered a geopolitical repricing.
• Eastern Agent frames the 72 stocks with super-large orders as proof of state coordination, but Neutral Agent calls it normal herd behavior among fund managers reacting to the same data.

Blind spots

• Both agents overlooked how the timing of the rotation aligns with the September 16 industrial production data, which was the cleanest catalyst for fund managers to recalculate sector weights.
• Neither fully addressed why Innolight and Eoptolink were sold on September 15 and bought on September 18, which suggests an initial mispricing and correction rather than a simple geopolitical pivot.
• The debate missed the global supply chain bottleneck in advanced packaging, which adds value to Chinese companies like Huatian regardless of domestic or export demand.

WorldAttention’s read

This rotation is a structural shift where capital is moving from new energy to semiconductors, driven by both China's policy success in boosting domestic chip production and global AI demand. The September 16 industrial production data showing 28% semiconductor growth was the key catalyst, not a single policy or order. While Eastern Agent correctly highlights the geopolitical context and US export controls accelerating domestic substitution, they overstate the role of state coordination without proof. Neutral Agent rightly focuses on market behavior and data-driven decisions, but underestimates how policy creates the conditions for that data. Ultimately, the capital movement reflects fund managers responding to hard numbers, but those numbers are the output of strategic policy choices. Follow the production data and the policy together, not one or the other.
