Report Industry Investment Rating No relevant content provided. Core Viewpoints - This week, the trading behavior of various institutions was generally subdued.

Funds' net purchase of credit bonds was 3.4 billion yuan, the third - highest since August [10]. - Looking ahead, attention should be focused on the recovery of allocation power. For banks, the easing of government bond supply pressure in the fourth quarter may boost large banks' purchasing power. For insurance companies, after the reduction of product predetermined interest rates, the slowdown of liability - side expansion may be a long - term trend, and the "rush to allocate" situation in previous years may not be repeated in the fourth quarter [10]. Summary by Directory 1. Overall Sentiment: Bond Market Vitality Index Declined Slightly - The bond market vitality index was compiled based on the historical quantile levels of bond market leverage ratio, turnover rate, bond fund duration, and implied tax rate of China Development Bank bonds since 2022 and their correlation coefficients with bond market trends.

Buying and Selling Strength and Bond Type Selection: Large Banks Continuously Buy Short - Term Bonds, Funds Focus on Credit Bonds - In the current bond market, the order of net buying strength was money market funds > funds > large banks > wealth management > securities firms > others > insurance > other product types > foreign banks, and the order of net selling strength was joint - stock banks > city commercial banks > rural financial institutions.

1. Report Industry Investment Rating No information provided in the content. 2. Core View of the Report - The pricing power of funds in the bond market has further increased, and there are still short - term long - trading opportunities. The high correlation between funds and interest rate trends has been further strengthened this year, and low interest rate fluctuations imply the enhancement of funds' pricing power in the bond market.
