Sector rotation and structural differentiation may continue

China Galaxy Securities stated that external constraints have shown marginal easing, providing fundamental support for the market's volatile recovery. However, due to capital gaming and divergence, the market's operational process will still be accompanied by fluctuations and repetition, and sector rotation and structural differentiation may continue. Three core factors persistently influence market pricing and trend rhythm. First, the trajectory of crude oil prices amidst repeated geopolitical friction. Second, marginal changes in expectations for the Federal Reserve's monetary policy. Third, domestic policy expectations and the pace of implementation.

Guotai Haitong believes that due to the significant market correction in July leading to damaged microstructure and weakened market confidence, market repair requires time to exchange expectations (turnover), and some recent fluctuations are normal. From a fundamental point of view, with falling risk-free interest rates, capital market system reform, and economic structural transformation, the market has strong support, and the historical process of a "transformational bull" will not end due to this setback. Looking ahead, the stock market will gradually usher in a "golden autumn market," and proactive deployment is recommended. The autumn market is viewed favorably. 1) Emerging technology and materials: Accelerated enterprise AI penetration, combined with improvements in domestic open-source model capabilities, will drive long-term growth in AI industries and computing power (core stocks). Recommendations include semiconductor (core stocks) equipment/domestic chips (core stocks)/communication equipment/non-ferrous metals/non-metallic new materials. 2) Advantageous manufacturing: Chinese enterprises face global demand and participate in global competition, forming new growth momentum and competitive advantages. Recommendations include power equipment/mechanical equipment/pharmaceuticals. 3) Large finance and high dividend: Stable return expectations are equally important. Recommendations include brokerages/banks and high dividend stocks.

China Merchants Securities stated that the recent rapid market rebound followed by a consolidation phase is essentially based on the Federal Reserve's TACO and non-farm employment data, trading on accommodative liquidity and expectations of interest rate cuts. For the market, the systemic recovery and risk appetite improvement driven by the resonance of macro and micro liquidity improvements since August may have entered its final stage. Coupled with the approaching window for concentrated release of semi-annual report performance, the market will focus more on structural opportunities from the earnings theme.

Huatai Securities research report points out that last week, overseas disturbances intensified. Japan's interest rate hike expectations drove a tightening of global liquidity expectations, putting pressure on Hong Kong stocks, especially the Hang Seng Tech Index. The A-share market experienced a volatile divergence, with no strong main themes. In the short term, the oversold rebound of the STAR Market and ChiNext is nearing its end, and the market is entering a phase of bottoming, consolidation, and rebalancing. In the medium term, July economic data showed external demand is strong while internal demand is temporarily weak, with effective demand awaiting catalysis. However, the scope of improving mid-cycle conditions is expanding, and the direction of upward earnings revisions aligns with the clues of improvement in the business cycle. The foundation for an upward trend remains unchanged. Attention should be paid to the policy window in the third quarter and signals of expansion in the breadth of earnings recovery. In terms of allocation, the AI chain remains the preferred choice, with communication equipment ranking first, followed by the domestic computing power chain and AI power. Other directions to watch include CXO leaders with stable earnings expectations, non-ferrous metals, and leaders in the export chain. Dividend positions should be maintained, with a focus on low-volatility banks and transportation.

China International Capital Corporation (CICC) stated that the fundamentals of technology growth are still being realized. Major technology companies are maintaining or increasing their AI capital expenditure. The demand for computing power, cloud business growth, and AI commercialization are mutually verifying each other. The recent global AI sector adjustment has digested some of the high crowding and high valuation risks, and the risk-reward ratio for technology growth has improved. The trading volume ratio of A-share TMT sectors has fallen from a historical high of 52% to 42%. With fundamentals continuing to materialize, combined with the reduction in crowdedness, the risk-reward ratio for technology growth has improved.
