Market Sentiment and Outlook - According to Galaxy Securities, the A-share market experienced increased volatility last week, with market sentiment becoming more cautious compared to previous periods. The outlook suggests that the A-share market is likely to continue a trend of oscillating upward, but short-term volatility risks should be monitored, particularly regarding marginal changes in market volume [2]. Growth Sectors - Growth sectors demonstrated high levels of prosperity in the first half of the year. As industry trends continue to strengthen, more clues of prosperity are expected to emerge, potentially forming a rotation theme. Short-term market fluctuations may increase [2]. Investment Opportunities - Industries such as machinery and electrical equipment are identified as having rebound potential, warranting attention to their capital inflow. Additionally, low-position sectors, particularly certain consumer sub-sectors, may strengthen due to policy support [2]. Long-term Focus - From a medium to long-term perspective, attention should be given to the improvement of supply-demand dynamics and industry profit recovery, which could drive the "anti-involution" concept. Assets with valuation safety margins, undervalued service consumption sectors, and technology self-reliance benefiting from rapid domestic high-tech industry development are also highlighted as potential investment targets [2].
