Market Overview - The A-share market experienced a collective decline on April 28, with the Shanghai Composite Index down by 0.2%, the Shenzhen Component down by 0.62%, and the ChiNext Index down by 0.65%. The total market turnover was 1,076.7 billion yuan, a decrease of 60.3 billion yuan from the previous day, with over 4,100 stocks declining [1]. Banking Sector Performance - The banking sector showed resilience, with stocks such as Industrial and Commercial Bank of China, China Construction Bank, Jiangsu Bank, and Chengdu Bank reaching historical highs. Citic Securities noted a slight decrease of 0.37 percentage points in the proportion of bank stocks among actively managed fund heavyweights compared to the previous quarter. In the short term, external disturbances are expected to impact market sentiment, but the banking sector is considered to have stable fundamentals and significant relative value, suggesting an increase in allocation [2]. PEEK Materials and Robotics Market - PEEK materials stocks performed well, with companies like Xinhan New Materials and Kent Shares rising over 10%. The global humanoid robot market is projected to grow from approximately 1 billion dollars in 2024 to 15 billion dollars by 2030, with a compound annual growth rate exceeding 56%. PEEK materials are expected to benefit from this growth due to their lightweight and strong properties, which are essential for humanoid robots [2]. Individual Stock Movements - Asia Pacific Industry experienced significant volatility, opening at the daily limit down and later surging to the limit up, achieving a turnover of 178 million yuan and a turnover rate of 19.29%. Institutional buying was noted, with one institution net purchasing 2.5742 million yuan. Conversely, Puli Pharmaceutical faced a sharp decline of over 77% due to entering the delisting period, with its stock price closing down nearly 74% at 0.65 yuan per share, resulting in a market cap reduction to 365 million yuan [3]. Market Outlook - The market is expected to maintain a volatile trend due to the upcoming "May Day" holiday, with institutions predicting a high probability of continued fluctuations unless substantial positive news emerges. Dongwu Securities suggests that without significant catalysts, the market is likely to remain in a consolidation phase. Galaxy Securities indicates that while market sentiment has shown some recovery, overall caution persists, reflected in the lack of significant volume increase. It is recommended to focus on medium to long-term strategies and be prepared for potential style shifts post-holiday [4]. Sector Focus - Short-term investment opportunities are suggested in sectors such as banking, electricity, beauty, and automotive, while mid-term focus should be on "new quality domestic growth" sectors driven by domestic demand and growth potential, including new consumption and AI [4].
