Core Viewpoint - The article introduces the "China Securities Stock-Bond Constant Series Index," which combines stocks and bonds to provide investors with asset allocation tools with varying stock-bond ratios, emphasizing the importance of dividend, cash flow, and core broad-based categories in A-share asset allocation [3][4]. Group 1: Index Overview - The China Securities Index has released six series of stock-bond constant indices, totaling 24 individual indices, including the Shanghai Dividend Stock-Bond and the Dividend Low-Volatility Stock-Bond series [7][8]. - These indices adopt a higher bond ratio, leading to a more stable long-term performance, with expected returns close to "fixed income+" [8]. Group 2: Stock-Bond Allocation Strategy - The stock-bond allocation strategy is a common asset allocation approach, enhancing portfolio stability by balancing the high volatility of stocks with the stability of bonds [4]. - Common stock-bond ratios include Graham's recommended 50/50 strategy, a more aggressive 70/30, and a conservative 30/70 [4]. Group 3: Index Composition - The Shanghai Dividend Stock-Bond series consists of the Shanghai Dividend Index and the Shanghai 0-5 Year High-Grade Credit Bond Yield Strategy Index, with ratios of 10:90, 20:80, and 30:70 [9]. - The Dividend Stock-Bond series combines the China Securities Dividend Index with the China Securities 0-5 Year High-Grade Credit Bond Yield Strategy Index, also using the same ratios [10]. - The Dividend Low-Volatility Stock-Bond series includes the China Securities 800 Dividend Low-Volatility Index and the China Government Bond Index, maintaining the same ratios [11]. - The A500 Exchange Stock-Bond series uses the China Securities A500 Index and a combination of exchange government bonds and policy financial bonds, with five allocation levels [12]. - The Cash Flow Exchange Stock-Bond series employs the China Securities 800 Free Cash Flow Index and the same bond combination, also with five allocation levels [13]. - The Dividend Low-Volatility Exchange Stock-Bond series utilizes the China Securities 800 Dividend Low-Volatility Index and the bond combination, maintaining five allocation levels [14]. Group 4: Performance Analysis - All indices have achieved positive returns due to their higher bond ratios, indicating a favorable long-term holding experience [19]. - As the stock allocation increases, the returns of most indices tend to rise, although the increase in annualized volatility often outpaces the rise in returns [20]. - Recent performance of dividend, low-volatility, and cash flow indices has been strong, but past performance does not guarantee future results [21]. Group 5: Investment Considerations - The article suggests that for lower risk tolerance, the bond ratio can be adjusted to 70% or more, akin to a fixed income+ strategy, while those who can tolerate some volatility may increase stock allocations [23]. - It emphasizes the importance of diversifying stock selections across dividend, low-volatility, cash flow, and core broad-based indices [23]. - The construction of a government bond and policy financial bond combination is proposed as a strategy for bond asset selection, considering the level of risk-free interest rates [23].
