- The "PB-ROE-50" strategy is based on the idea of identifying market expectation gaps and enhancing portfolio returns by incorporating surprise factors such as SUE and ROE year-on-year growth.

Lower standard deviation indicates higher concentration, while higher standard deviation suggests concentration is breaking down[25][28][26] - The "Institutional Research Strategy" includes public fund research stock selection and private fund research tracking strategies. It selects stocks based on the number of times a company is researched and its relative performance before the research.

1. Report Industry Investment Rating No information provided regarding the industry investment rating in the report. 2. Core Views of the Report - In the first half of 2025, over half of the convertible bond issuers saw year - on - year revenue growth. It is advisable to focus on some industry targets with in - line mid - year reports and reasonable valuations, while avoiding targets with lower - than - expected mid - year reports and high prices and premiums. Also, pay attention to the repair market of individual bonds with marginal improvements in post - mid - year - report orders/ prices in the 'anti - involution' industries and track policy catalysts from the third quarter onwards [1][2][10][16]. - Currently, A - shares still show good allocation value in terms of risk premium. In the convertible bond market, considering the impact of refinancing policies, there is some support on the demand side under the background of supply contraction. However, as the current overall valuation of convertible bonds is at a relatively high level, caution should be exercised regarding correction risks. Attention should be paid to hot themes, the repair opportunities of low - level technology growth sectors, and industries with improved domestic demand and high - dividend sectors [18]. 3.
