1. Report Industry Investment Rating No relevant information provided in the text. 2. Core View of the Report - In the current market context, increasing the allocation of convertible bonds related to popular themes may be the key action for the portfolio to achieve excess returns. Although overseas tariff factors disrupt the domestic economic recovery process and the profit side of listed companies may not recover rapidly in the short term, after the end of the intensive performance disclosure period in May, the previous negative factors have been gradually priced in. The government has released liquidity to support the economy and the securities market. It is expected that the market will likely show characteristics of increasing risk appetite, and the valuation side will be the main support for the strengthening of the market [2][6]. - To benefit from the increase in the market valuation level, it is advisable to appropriately increase the allocation of convertible bonds related to themes. Although the profit side of some theme - related convertible bonds has not yet reached an inflection point, stock pricing often leans towards future long - term growth. The negative factors on the profit side of some targets have been fully priced in by the market in the early stage, and investors tend to give a higher valuation premium to stocks related to new productive forces. Therefore, under the current background, convertible bonds related to popular themes are more cost - effective in creating excess returns [2][9]. - By analyzing the excess return performance of the CSI 2000 and the Wind AA - rated and below index from 2020 to the present, it is found that when the market trading volume exceeds 1.5 trillion yuan, the CSI 2000 shows relatively obvious excess returns compared to the Wind All - A Index in the stock dimension, and the trend is more obvious in the convertible bond dimension. Convertible bonds related to popular themes are more characteristic of small - cap stocks and low - rated convertible bonds, and are more likely to create excess returns when the trading volume recovers [2][9]. - Relevant convertible bonds can be mined by combining annual reports and public research records. The real economy has been gradually transforming towards new productive forces in recent years. Listed companies will disclose new investment and transformation directions in their annual reports and conduct communication and research activities with the capital market after the disclosure of regular reports. Therefore, the 2024 annual reports and public research records since 2025 are important for mining relevant theme - related convertible bonds [2][13]. 3.
