Group 1 - The core view of the report indicates that the credit bond market typically performs better after the Spring Festival compared to before, with a historical probability of 60%-70% for yield declines in various bond types post-festival [1][21][22] - Specific bond types such as Tier 2 capital bonds (71.43%) and 10Y government bonds (70.00%) show the highest probability of yield decline if positioned before the Spring Festival [1][21] - The report highlights that the average yield decline of urban investment bonds is 2.4 times that of government bonds, suggesting a high elasticity in yield changes for credit bonds [1][21] Group 2 - The report notes that while there is a tendency for the credit bond market to follow pre-festival trends, there is still a 50% chance of trend reversals, particularly for 10Y government bonds, which have only a 28.57% probability of continuing the pre-festival trend [2][22] - The report identifies three main reasons for the seasonal effect: the rigid demand for bonds from institutions at the beginning of the year, the seasonal liquidity effects around the Spring Festival, and the data vacuum period for macroeconomic indicators [3][27][30][31] Group 3 - The report suggests a short-duration investment strategy focusing on cities with strong industrial bases and financial support, recommending bonds with maturities of 3-5 years to mitigate risks from potential interest rate fluctuations [4][36] - It emphasizes the importance of monitoring the issuance volume in the primary market, which typically decreases before the holiday, and anticipates a stable low yield spread in the coming months due to ongoing liquidity conditions [32][33]
