Market Overview - The A-share market continued to rebound with reduced trading volume, with the Shanghai Composite Index returning to 3900 points, and nearly 4600 stocks in the green. The Shanghai Composite Index rose by 1.20%, the Shenzhen Component Index by 1.97%, and the ChiNext Index by 2.92% at midday [1]. Market Signals - The market's continued rise on low volume indicates a structural differentiation in capital flow, characterized by "passive inflow + active outflow." Stock ETFs have seen continuous net inflows, providing a "bottoming" effect for market liquidity, while margin trading balances have decreased and northbound capital has become more cautious due to external uncertainties. This suggests a lack of systemic selling pressure, but the market's upward movement relies more on existing stock dynamics and event-driven catalysts [2]. Sector Performance - **Apple Concept Stocks**: The fruit supply and consumer electronics sectors saw a rally, with stocks like Matrix Technology rising over 10%. This surge was driven by strong sales of the iPhone 17 series, which saw a 14% increase in sales compared to the previous generation within the first ten days of launch [4]. - **Storage Chip Sector**: The semiconductor sector strengthened, led by storage chip stocks such as Shannon Semiconductor, which rose over 10%. Concerns about DRAM supply becoming more severe by 2026 were highlighted, as the demand for HBM chips is significantly higher than traditional DRAM products [5]. - **CPO Concept Stocks**: CPO stocks continued to rebound, with companies like Huylv Ecology achieving consecutive gains. Demand for 1.6T optical modules has been revised upwards significantly, indicating strong growth in AI training and inference network bandwidth needs [6]. - **Synthetic Diamond Sector**: Stocks related to synthetic diamonds were active, with Huanghe Xuanfeng achieving consecutive gains. The announcement of a successful cultivation of a 156.47-carat synthetic diamond has generated interest [8]. Institutional Insights - **CITIC Construction Investment**: The market is in a consolidation phase with a rotation of styles. The overall bull market logic remains intact, supported by structural prosperity and ample capital. Key sectors to watch include dividends, precious metals, large financials, and AI [9]. - **China Galaxy Securities**: The market is expected to experience a phase of cautious sentiment due to external trade uncertainties. Focus should be on sectors with strong policy support and earnings certainty, particularly dividend stocks and large consumption sectors [10]. - **Orient Securities**: The market is likely to remain in a range-bound state, with a balanced approach to sector allocation. Attention should be given to semiconductor equipment, AI, and coal sectors, which are expected to perform well due to price expectations and seasonal demand [11].
