Group 1: Report Industry Investment Rating - The report does not mention the industry investment rating. Group 2: Core View of the Report - This week, all Treasury bond futures closed lower. The closing prices of the 30 - year (TL), 10 - year (T), 5 - year (TF), and 2 - year (TS) Treasury bond futures in the main contracts decreased by 1.54%, 0.32%, 0.17%, and 0.04% respectively compared to last week. The overall Treasury bond futures market showed a trend of rising first and then falling, with prices of all - term contracts declining. Due to the support of loose funding at the short - end, TF and TS performed better than TL and T. After the increase in equity risk appetite, Treasury bond futures were more likely to fall than rise. Although the weak economic data released on Friday morning supported a rebound in the morning session, the market then returned to the bearish direction [4].
