1. Report Industry Investment Rating No information about the report industry investment rating is provided in the given content. 2. Core Viewpoints of the Report - The long - end of secondary capital bonds and perpetual bonds showed significant strength last week, with the long - end yield decline more prominent than the short - end. The short - end yield of secondary and perpetual (二永) bonds has been at a historical low, making further decline difficult. Institutions started to bet on medium - and long - duration bonds, with the 7 - year bond being the most favored. The 7 - year spread quantile is still relatively high, indicating potential for further betting [2][9][10]. - The curves of general credit bonds and urban investment bonds have flattened. The general credit bond curve shows characteristics of "flattened short - end, steepened middle - section, and declined long - end", while the urban investment bond curve shows "flattened short - end, locally steepened middle - section, and differentiated long - end" [3][11][13]. - In terms of trading volume, short - end trading volume increased, while the trading volume of general credit bonds decreased slightly. High - yield urban investment bond trading was mainly concentrated in regions such as Beijing, Shandong, Hunan, and Guangdong [15][17][22]. - In primary issuance, the net financing of urban investment bonds in general credit bonds recovered significantly, while the net financing of financial bonds showed a significant outflow, and the net financing of science and technology innovation bonds was negative [23][26][29]. 3.
