从“股债失联”到“股债同源”

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The probability of "stocks and bonds being homologous" is increasing, and they are likely to be homologous to the nominal growth rate, which is of greater macro - significance to the country than the real growth rate [34] - When the stock index returns to EPS and the bond market level matches the current policy and fundamental aspects, the probability of stocks and bonds being homologous increases [34] - The overall long - term interest rate center's rise and fall will return to fundamental factors: growth or prices [32] 3. Summary by Relevant Catalogs "Stock - Bond Disconnection" - After "9.24" in 2024, both stocks and bonds were bullish under the stimulus of loose monetary policy. In 2025, there was a "seesaw" form where stocks were strong and bonds were weak, with the median return of a certain scale of interest - rate bond public funds around 0.2%. The stock index rose nearly 800 points while the interest rate only increased by 20 points [7][8] - The reason for "stock - bond disconnection" is that they have their own driving main lines. In 2025, the driving factors of stocks and bonds were mostly different, but there was a common linkage effect during the anti - involution market from June to August [9][11] - The main line of the bond market in 2025 was the revision and adjustment of expectations, including the revision of policy expectations and economic expectations [12][17] "Increasing Probability of Stock - Bond Homology" - The bull market of stocks requires both PE and EPS. Currently, it seems to enter a period where EPS needs to take over. PE - driven stock markets tend to weaken the stock - bond seesaw effect, while EPS - driven ones strengthen it. When the stock market focuses on EPS, the probability of stock - bond homology increases [22] - The long - term interest rate's rise and fall in the past year was mainly determined by the term premium. Currently, the term premium is at a reasonable level, and the overall long - term interest rate center's rise and fall will return to fundamental factors such as growth or prices [32] - When the stock index returns to EPS and the bond market level matches the current policy and fundamental aspects, the probability of stocks and bonds being homologous increases [34] "What is the Focus of Homology?" - In terms of the 2035 goals, the real growth has limited elasticity, while prices still have elasticity. Industry profit changes are closely related to prices, which is crucial for the stock market. Whether to get out of deflation is crucial for the bond market [38] - Since 2016, there has been significant differentiation in the internal price trends. Non - food (or core) prices are more demand - driven, while food prices are more supply - driven. Monetary policy and market interest rates pay more attention to demand - dominated prices, especially non - food prices [41][43][47] - Under neutral assumptions, there is a possibility of getting out of deflation. The risk lies in whether the month - on - month data can reach the neutral level in recent years. The trend is determined, and it is unlikely to return to the 2024 pattern [50][51] - "Anti - involution" is an important policy arrangement. In the short - term, the implementation path is under observation, with the goal of improving the profit margins of key industries. In the long - term, the path is clear, aiming to establish a unified national market through mergers, reorganizations, and reforms [60][61] - In the short - term, administrative production control may be used to improve industry profit margins. Attention should be paid to whether there will be production control policies for anti - involution key industries, which account for over 30% of China's PPI [69][70]
