1. Report Industry Investment Rating There is no industry investment rating provided in the report. 2. Core Viewpoints of the Report - In the first half of 2025, the A - share market showed an interval - oscillating pattern with significant structural differentiation. The market style shifted from traditional core assets to growth - type targets. - Policy support is an important factor for the market, but the economic recovery still faces internal and external challenges. The full recovery of economic endogenous momentum requires stronger policy support. - In the short term, the market will continue to oscillate. It is advisable to reduce long positions in small - and medium - cap stocks on rallies. For empty - position investors, it is recommended to be patient and focus on layout opportunities when the index pulls back to the lower edge of the interval. In the medium - and long - term, allocation should be cautious, with emphasis on tracking the progress of profit repair and policy effects [3]. 3. Summary by Relevant Catalogs 3.1股指延续区间震荡态势 - **行情回顾**: From the beginning of the year to mid - March, the A - share market oscillated upward due to the acceleration of the AI industry and policy benefits. Then it adjusted under the impact of Trump's "reciprocal tariffs". From mid - April to the end of the year, it regained its upward momentum due to domestic policy support and the easing of Sino - US trade frictions. Structurally, small - and medium - cap stock index futures were more elastic than large - cap stocks, and the CSI 1000 led the gains several times in the first half of the year [8]. - **行业表现**: In the first half of 2025, industries showed significant differentiation. Precious - metal - related non - ferrous metals and high - dividend bank sectors led the gains, while coal, food and beverage, and real estate sectors declined. Different time periods had different dominant styles [10]. - **股指基差**: The expansion of market - neutral strategies and the increase in index dividend rates led to an increase in index futures discounts. It is expected that in the second half of 2025, the seasonal discount of stock index futures will be relatively larger than in previous years, but the absolute degree of discount will gradually decrease [11][14][16]. 3.2市场估值：关注盈利带动估值消化 - **中证500和中证1000指数**: As of June 27, the price - to - book ratios of the CSI 500 and CSI 1000 indexes were at historically low - to - medium levels, at 1.91 and 2.13 respectively, in the 49.20% and 23.71% quantiles of the past 10 years [20]. - **上证50和沪深300指数**: As of June 27, the price - to - earnings ratios of the SSE 50 and CSI 300 indexes were relatively high, while the price - to - book ratios were relatively low, showing a valuation divergence. The recovery of profitability is crucial for digesting the price - to - earnings ratio and repairing the divergence [22]. - **指数拥挤度**: The market style may continue to shift towards growth - type targets. The relative valuation of small - cap growth - style assets has increased significantly, and the difference in the crowding degree between the CSI 500 and CSI 1000 indexes has narrowed [24][28]. - **股债性价比**: The stock market does not have an obvious relative advantage. After the significant rise in the market since the end of September, the stock market is running at a low level. If the Fed cuts interest rates in the second half of the year, the yield of interest - rate bonds is expected to continue to decline, and the relative valuation of the stock market is still at a relatively high level [34]. - **估值小结**: After the valuation repair since the end of September, the relative valuation advantage of the stock market over bonds has weakened. The market is internally differentiated, and the valuation repair is faster than the profit recovery. The difference in the crowding degree between the CSI 1000 and CSI 300 indexes will continue to oscillate upward [36][37]. 3.3国内预期向现实转化仍存阻力 - **金融传导效率好转，政策效果需进一步释放**: In May, the year - on - year growth rate of M1 money supply rebounded. The conversion from M2 to M1 began to appear, but the long - term investment willingness of real - economy enterprises was still weak, and the credit policy to stimulate consumption had not fully taken effect [37]. - **通缩压力未完全消退，利润水平修复仍处于筑底阶段**: The net profit of constituent stocks of each index is still at the bottoming stage, showing differentiation. The profit of large - scale industrial enterprises has not formed a continuous repair trend. The price level shows that the economy is still on the verge of deflation, and the demand - side momentum has not fully recovered [39][44]. 3.4资产配置转移预期提升，资本账户压力或将缓解 - **资产配置转移预期提升**: The central bank cut the reserve ratio and policy interest rates, and commercial banks lowered deposit rates. The "deposit relocation" expectation has increased, and funds are flowing from traditional bank deposits to bank wealth management and the capital market, which is expected to bring sufficient allocation funds to the A - share market [46][49]. - **美元主导因素转变，资本金融账户压力或将缓解**: The US dollar is changing from a typical counter - cyclical asset to a pro - cyclical asset, and its weakening expectation is increasing. The RMB's passive depreciation pressure is expected to be substantially relieved, and the capital and financial accounts may enter a repair channel [53][55]. - **关税措施修正收缩空间有限，经常账户仍存在明显压力**: Sino - US trade is still affected by tariffs. The US faces structural contradictions, and the "Big and Beautiful Act" may support the US's tough attitude towards import tariffs, so the domestic current account still faces obvious pressure [57][62][63].
