Core Viewpoint - The article emphasizes the importance of understanding the interplay between industrial revolutions and financial theories, highlighting how advancements in the real economy drive the evolution of asset valuation and allocation methods [4][5]. Group 1: Historical Context of Wealth and Financial Theory - Approximately 2000 years ago, the widespread use of iron tools in agriculture marked the beginning of material surplus, representing humanity's initial wealth [6]. - The Talmud introduced a simplistic wealth allocation principle of "1/3 land, 1/3 business, 1/3 savings," which lacked optimization efforts and was based on experiential rules [6]. - About 100 years ago, the outcomes of two industrial revolutions led to exponential growth in production capacity, shifting wealth accumulation from aristocracy to the emerging bourgeoisie, who began to view wealth as a means to expand production capabilities [6]. Group 2: Evolution of Investment Theories - The introduction of value investing by Benjamin Graham represented a breakthrough in asset allocation methodology, moving from a zero-dimensional approach to a more sophisticated understanding of investment value [6]. - The third industrial revolution, which transitioned humanity from the electrical age to the information age, democratized wealth ownership and introduced complex asset classes, leading to the development of modern portfolio theory by Harry Markowitz and William Sharpe [7]. - This theory incorporated the concept of risk-adjusted returns, fundamentally changing how investors construct portfolios and view expected returns and risks [7]. Group 3: Contemporary Challenges and Opportunities - Recent global events, including the COVID-19 pandemic and geopolitical tensions, have prompted a reevaluation of expected returns and risk factors in investment strategies [8]. - The article notes that the historical reliance on financial returns as the sole measure of investment success is being challenged, as investors seek to understand and incorporate a broader range of risk factors into their decision-making processes [8].

- The report introduces five ETF quantitative strategies: macro timing strategy, momentum selection strategy, low-volatility diffusion industry rotation strategy, fund flow strategy, and quantile regression strategy[41][43][52] - **Macro Timing Strategy**: This strategy uses Gaussian distribution-based Black-Litterman (B-L) and Copula distribution-based B-L models to calculate ETF allocation weights. It incorporates economic cycle segmentation to constrain asset allocation weights across different ETF categories. Representative ETFs include stock ETFs (e.g., CSI 300 ETF), bond ETFs (e.g., government bond ETF), commodity ETFs (e.g., gold ETF), and currency ETFs (e.g., Silver Day Profit A). The strategy achieved an annualized return of 9.43%, Sharpe ratio of 0.66, Calmar ratio of 0.52, and maximum drawdown of -13.21% since 2020[43][45][46] - **Momentum Selection Strategy**: This strategy utilizes XGBoost to predict ETF upward probability as a momentum indicator and historical quantile of fund shares as a crowding indicator. It selects ETFs with high momentum and low crowding within sectors, adjusting allocation weights based on crowding levels. The strategy achieved an annualized return of 13.93%, Sharpe ratio of 1.33, Calmar ratio of 1.21, and maximum drawdown of -23.14% since 2020[53][54][55] - **Low-Volatility Diffusion Industry Rotation Strategy**: This strategy applies industry diffusion index factors combined with volatility adjustments to design a low-volatility industry rotation model. It matches ETFs to industry indices based on correlation and selects top ETFs for monthly rebalancing. The strategy achieved an annualized return of 12.22%, relative excess return of 3.21%, Sharpe ratio of 0.91, and maximum drawdown of -21.43% since 2020[61][62][63] - **Fund Flow Strategy**: This strategy uses weighted fund flow indicators and risk metrics to rank industries, selects ETFs based on turnover rate and premium/discount rate, and optimizes allocation weights using second-order stochastic dominance. The strategy achieved an annualized return of 11.24%, Sharpe ratio of 1.12, Calmar ratio of 1.03, and maximum drawdown of -19.21% since 2020[64][67][68] - **Quantile Regression Strategy**: This strategy employs quantile random forest (QRF) to predict future distribution characteristics of technology sector indices, selects ETFs based on liquidity and scale, and adjusts positions using MACD and volatility metrics. The strategy achieved an annualized return of 15.62%, Sharpe ratio of 1.21, Calmar ratio of 1.15, and maximum drawdown of -21.43% since 2020[71][72][73]

Group 1: Report Summary - The report analyzes the settings of domestic and international stock-bond constant indices and their impacts on underlying assets and the asset management product ecosystem. Since 2024, China Securities Index Co., Ltd. has released a series of stock-bond constant indices, with 9 allocation strategies, 5 stock-bond ratio gradients, and a total of 39 stock-bond constant ratio indices [1][2][112]. - Stock indices in the stock-bond constant indices focus on 2 smart beta indices (dividend and cash flow) and the A500 index representing industry-balanced mid- and large-cap stocks. Bond indices correspond to a combination of medium- to high-grade credit and treasury and policy financial bond indices [1][2][112]. - From a 3-year perspective, stock-bond constant indices are in a low-drawdown, medium-elasticity range. The stock-bond ratio determines cost-effectiveness, the bond style determines the return bottom, and the equity index determines return elasticity. Historically, the 20:80 stock-bond constant index has a better risk-return ratio than many secondary bond funds [2][100][113]. Group 2: Background of Stock-Bond Constant Indices - In 1952, Harry M. Markowitz proposed the modern portfolio theory, providing a mathematical basis for asset allocation. Diversified asset allocation has become an important direction in wealth management, and multi-asset funds are key tools for implementing this strategy [15]. - The constant ratio strategy, especially the stock-bond constant ratio, is a common strategy in multi-asset index compilation. In the US market, the correlation between stocks and bonds varies with inflation and monetary policy. In the domestic market, stocks and bonds are mainly negatively correlated, and the correlation among stock indices has been decreasing [16][17][20]. Group 3: Basic Information and Risk-Return Characteristics of Stock-Bond Constant Indices 3.1 Basic Information of Stock-Bond Constant Series Indices - As of the end of November 2025, China Securities Index Co., Ltd. has released 100 multi-asset indices, covering strategies such as constant ratio, risk parity, volatility control, target date, and target risk [28]. - The newly released stock-bond constant series indices have 9 allocation strategies and 5 stock-bond ratio gradients, with a total of 39 indices. Stock indices focus on dividend and cash flow smart beta indices and the A500 index, while bond indices are a combination of medium- to high-grade credit and treasury and policy financial bond indices [32]. 3.2 Components and Industry Characteristics of Stock-Bond Constant Indices - The report focuses on the component stocks and sample adjustment of stock indices in stock-bond constant indices. For example, the CSI Dividend Index adjusts its samples once a year, and the CSI 800 Cash Flow Index adjusts quarterly [43][50]. - There are differences in the component stocks among the CSI Dividend Index, CSI 800 Cash Flow Index, and CSI A500 Index. The A500 Index emphasizes industry balance, while the Dividend Index is more concentrated in the financial and energy sectors [58]. 3.3 Return, Volatility, and Drawdown Performance of Stock-Bond Constant Indices - In the past 3 years, the CSI 800 Cash Flow Index has a higher annualized return, followed by dividend-related indices, and the A500 Index has the lowest return among the three. Among bond indices, medium- to high-grade credit bonds have a higher return-volatility ratio [61]. - In the past year, the performance of these indices has changed. The growth style represented by innovation has outperformed the dividend style, and the A500 Index has exceeded the CSI 800 Cash Flow and dividend-related indices in terms of return [74]. Group 4: Comparison between Stock-Bond Constant Indices and Active Fixed-Income Plus Products - Stock-bond constant indices have strong defensive capabilities. Based on the long-term weak negative correlation between stocks and bonds, the 10/90 and 20/80 stock-bond constant indices can reduce volatility and enhance portfolio defense [93]. - In the past three years, the overall return of stock-bond constant indices has been better than that of the WIND Secondary Bond Fund Equal-Weighted Index, and their volatility is lower. The 20:80 stock-bond constant index performs better than most secondary bond funds in the same maximum drawdown range [96][100]. - If stock-bond constant ETFs are launched, due to their low fees and high liquidity, some funds may switch from secondary bond funds to stock-bond constant ETFs, which may cause passive selling of secondary capital bonds and local structural frictions [106][108].
