1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The Chinese economy is in a marginal de - leveraging process, with the liability growth rate of the real - sector expected to decline. The government aims to stabilize the macro - leverage ratio, and the monetary policy will generally remain neutral and difficult to be continuously loose. The market is currently affected by risk preference, and the subsequent trends of risk preference, economic recovery, and the US economy need to be focused on [2][3][7] - In the context of the contraction of the national balance sheet, the allocation of financial assets should adopt a dumbbell - shaped strategy. The bond market is the large base, and the stock market is the small head. The stock allocation strategy is dividend plus growth, and the bond allocation strategy is duration plus credit - sinking [25] - In the contraction cycle, the equity - bond ratio favors equities to a limited extent, and the value style is more likely to be dominant. Red - dividend stocks with characteristics of non - expansion, good profitability, and survival are recommended [12][67] 3. Summary by Relevant Catalogs 3.1 National Balance Sheet Analysis - **Liability Side**: In July 2025, the liability growth rate of the real sector was 9.0%, with a lower - than - expected rebound. It is expected to decline to 8.9% in August and further to 8% by the end of the year. The government's liability growth rate is also expected to decline from 15.7% in July to 14.8% in August and 12.5% by the end of the year. The money market has tightened marginally, and the peak of the money market in August was likely in the first week [2][3][21] - **Monetary Policy**: The trading volume of funds decreased last week, and the price was stable. The one - year Treasury yield rose to 1.37%, and the term spread widened. The estimated lower limit of the one - year Treasury yield is 1.3%, the ten - year Treasury yield is about 1.6%, and the thirty - year Treasury yield is about 1.8% [3][22] - **Asset Side**: After a brief stabilization in June, the physical volume data declined again in July. The annual real economic growth target for 2025 is about 5%, and the nominal economic growth target is about 4.9%. Whether this will be the central target for the next 1 - 2 years needs further observation [4][23] 3.2 Stock - Bond Ratio and Stock - Bond Style - **Market Performance Last Week**: The money market tightened marginally, but risk preference increased. Stocks rose, and bonds fell. The equity growth style was dominant, and the stock - bond ratio favored stocks, breaking through the previous high on August 15th [6][26] - **Future Outlook**: The trend of risk preference is uncertain. There are three possible scenarios: range - bound fluctuations, a short - term upward trend, or a fundamental change in the subjective weighting of Chinese profitability. A portfolio of growth - type equity assets and long - term bonds is recommended, with a 70% position in the CSI 1000 Index and a 30% position in the 30 - year Treasury ETF [10][11][29] 3.3 Industry Recommendation - **Industry Performance Review**: The A - share market rose this week. The communication, electronics, non - bank finance, power equipment, and computer sectors had the largest increases, while the bank, steel, textile and apparel, coal, and public utilities sectors had the largest declines [35] - **Industry Crowding and Trading Volume**: As of August 15th, the top five crowded industries were electronics, computer, power equipment, machinery, and non - bank finance. The trading volume of the whole A - share market increased this week, with non - bank finance, real estate, and other sectors having the highest growth rates [36][38] - **Industry Valuation and Profitability**: The PE (TTM) of the comprehensive, communication, and other sectors increased the most this week, while the bank, steel, and other sectors declined. Industries with high 2024 full - year profit forecasts and relatively low current valuations include banks, coal, and oil and petrochemicals [41][42] - **Industry Prosperity**: External demand generally declined. The global manufacturing PMI decreased in July, and the CCFI index fell. Domestic indicators such as port throughput and industrial capacity utilization showed mixed trends [46] - **Public Fund Market Review**: In the second week of August, most active public equity funds outperformed the CSI 300. As of August 15th, the net asset value of active public equity funds was slightly higher than that in Q4 2024 [62] - **Industry Recommendation**: In the contraction cycle, the equity - bond ratio favors equities to a limited extent, and the value style is more likely to be dominant. An A + H red - dividend portfolio of 20 stocks and an A - share portfolio of 20 stocks, mainly concentrated in banks, telecommunications, and other industries, are recommended [12][67]

Summary of Key Points from Conference Call Industry or Company Involved - The discussion revolves around the relationship between the equity market, specifically the 中证 500 Index, and the bond market, particularly the 10-year government bond yield. Core Insights and Arguments - There exists a "seesaw effect" between the stock market and the bond market, where the 中证 500 Index and the 10-year government bond yield are positively correlated. Specifically, for every 100-point increase in the 中证 500 Index, the 10-year bond yield rises by approximately 0.9 basis points [1][2][5]. - The Bernanke three-factor model effectively decomposes the yield of the 10-year government bond, achieving an R-squared value of 0.85 when fitted to data since 2016. This model uses the 7-day reverse repo rate as a proxy for short-term rates, current CPI for inflation expectations, and the difference between social financing and M2 to represent economic conditions [1][4][7]. - The relationship between the 中证 500 Index and the 10-year bond yield shows a leading effect, indicating that an increase in the stock index can lead to a rise in bond yields in the following month [2][11]. - The bond market has already absorbed the impact of the recent rise in the equity market, with an increase of about 4-5 basis points in the bond yield since mid-June [14]. - If the equity market rises by an additional 5%, it could exert an extra pressure of about 3 basis points on the bond market, pushing yields to a range of 1.70% to 1.75%. A further 10% increase in the equity market could raise yields by approximately 6 basis points, resulting in a range of 1.75% to 1.80% [2][14]. Other Important but Possibly Overlooked Content - Different equity indices have varying degrees of influence on the 10-year bond yield. The 中证 1,000 and 中证 2000 indices show weaker correlation with the bond market compared to larger indices like the 上证综指 and 深证成指 [8][9]. - The structural integrity of the model is affected by the inclusion of large-cap indices, which can disrupt the original model's structure, particularly the impact of social financing minus M2 [9]. - The current market environment has led to a notable increase in the correlation between the 中证 500 Index and the 10-year bond yield, a phenomenon not seen in the past decade. This is attributed to stable fundamental and monetary conditions [15].

Summary of Conference Call Records Industry or Company Involved - The discussion revolves around the investment strategies and market dynamics in the context of style rotation, particularly focusing on large-cap vs small-cap and growth vs value styles in the Chinese stock market. Core Points and Arguments 1. **Style Rotation Framework**: The construction of a style rotation framework requires selecting appropriate indices to describe large-cap, small-cap, and growth vs value styles, considering macroeconomic cycles, market structure, and economic background that drive risk preference shifts [1][3][4] 2. **Historical Examples of Style Rotation**: Historical cases show a correlation between economic cycles and style rotation, such as the bull market in the ChiNext from 2013 to 2015 and the supply-side reforms in 2017, indicating that different styles perform well in different economic conditions [5] 3. **Current Index Usage**: The commonly used indices include the CSI 300 for large caps and the CSI 500 for small caps, but the CSI 1000 is increasingly viewed as a mid-cap index, suggesting a need for smaller indices like the CSI 2000 to represent small caps [7] 4. **Barbell Strategy**: Recent trends in the domestic market show a barbell strategy where small caps and value (dividend) stocks are performing well, reflecting a narrowing investment focus among investors [8] 5. **Long-term Style Judgement**: Long-term core style judgement relies on macro and meso indicators, while short-term factors include capital flow, sentiment, and institutional behavior, which can be analyzed quantitatively [9] 6. **Challenges in Style Index Construction**: The construction of style indices faces challenges such as overfitting due to excessive filtering conditions, which can compromise the purity of the style representation [10][11] 7. **Stability of Market Capitalization Distribution**: Maintaining a stable market capitalization distribution is crucial for effective backtesting over long periods, avoiding frequent adjustments to the benchmarks used for small-cap representation [13] Other Important but Possibly Overlooked Content 1. **Quantitative Analysis of Style Rotation**: Quantitative analysis can validate subjective perceptions of style rotation through multi-dimensional backtesting, utilizing factors from risk models like Barra [6] 2. **Growth Factor Selection**: Growth factors are selected based on pure metrics such as revenue growth and net profit growth, categorized into groups to better represent extreme growth styles during bullish phases [14] 3. **Value Index Characteristics**: The value index is constructed using simple metrics like P/E and P/B ratios, focusing on accurately reflecting undervalued stocks without additional factors that could distort its representation [15] 4. **Future Reporting Plans**: The company plans to provide detailed reports on specific strategies to investors and leadership in the coming days, indicating ongoing engagement and communication with stakeholders [16]

Core Viewpoint - Index rebalancing is a process that ensures the vitality of indices by removing stocks that do not meet criteria and adding new ones, which can lead to changes in stock valuations and investor strategies [3][5][6]. Group 1: Index Rebalancing Process - Index rebalancing is akin to a metabolic process, ensuring that indices remain representative and investable [4]. - There are two main types of index rebalancing: temporary adjustments due to special events and regular adjustments based on sample stability [7][9]. - Regular rebalancing occurs at different frequencies, such as quarterly, semi-annually, or annually, depending on the index [14][15]. Group 2: Impact on Valuations - The recent rebalancing on June 13 affected various indices, with changes in the number of stocks and their average price-to-earnings (P/E) and price-to-book (P/B) ratios [20][18]. - For instance, the Shanghai-Shenzhen 300 Index saw a decrease in P/E and a slight increase in P/B after adjusting 7 stocks [23]. - The CSI 500 Index experienced an increase in both P/E and P/B after replacing 50 stocks [24]. Group 3: Strategy Indices - Strategy indices, such as the CSI A500 and value strategies, often see different valuation impacts compared to market-cap weighted indices [30][32]. - The CSI A500 Index's recent rebalancing led to a decrease in P/E and a slight increase in P/B [31]. - The 300 Value Index typically sees a decrease in valuation metrics due to its focus on low P/E and P/B stocks [32]. Group 4: Market Behavior and Investor Strategies - Market-cap weighted indices can lead to a "buy high, sell low" scenario, as stocks that rise in value are included while those that fall are excluded [43]. - This phenomenon has historical precedence in markets like the U.S. during the tech bubble, where high-flying stocks were included in indices, leading to greater declines when the bubble burst [45]. - To mitigate these effects, investors may consider strategy indices that do not rely on market capitalization, thus avoiding the pitfalls of chasing high valuations [47][51].
