Group 1: Report's Industry Investment Rating - No information provided in the report Group 2: Report's Core Viewpoints - This week (0126 - 0130), there were significant fluctuations in major asset classes. The short - term yields of US stocks, precious metals, and US bonds were significantly adjusted, and the US dollar was slightly repaired. The market believes that the Fed's interest rate cut path in 2026 may remain restrained. The report maintains the previous view that a low - interest - rate environment is necessary and effective, and safe - haven assets such as US bonds and gold will still face increased allocation after short - term fluctuations. Currently, there are no necessary conditions for the Fed's monetary policy to shift [1]. - Overseas uncertainties have led to significant fluctuations in domestic risk - based assets. The report previously suggested that the convertible bond strategy should prioritize "controlling drawdowns" and also pay attention to high - probability pro - cyclical targets. Subjectively, it is recommended to conduct high - low switching within convertible bonds to control drawdowns and adopt a "dumbbell" - type allocation for hedging. In the medium - term, it is difficult to infer a scenario of overall valuation compression for convertible bonds. The core is to control drawdowns, emphasize timing, and balance the rhythm and structure of convertible bond allocation [1]. - The top ten high - rated, medium - low - priced convertible bonds with the greatest potential for par premium rate repair next week are: Liqun Convertible Bond, Bengang Convertible Bond, Guotou Convertible Bond, Industrial Convertible Bond, Nenghua Convertible Bond, Hope Convertible Bond 2, Wentai Convertible Bond, Lutai Convertible Bond, Yingfeng Convertible Bond, and Lianchuang Convertible Bond [1] Group 3: Summary According to the Table of Contents 1.
