1. Report Industry Investment Rating No information provided in the given text. 2. Core Viewpoints of the Report - In the short - term, the investment demand for convertible bonds from insurance and annuity remains. With the shrinking of traditional high - quality underlying bonds like banks, convertible bond funds may flow to low - price, high - grade medium - large - cap convertible bonds in sectors such as utilities, transportation, environmental protection, and construction. The valuation decline of medium - low - price and balanced convertible bonds is controllable, and the valuation of high - grade convertible bonds may rise. In the long - term, if the new issuance space of convertible bonds remains unopened, it may significantly affect the market positioning of convertible bond assets, especially if new medium - high - grade convertible bonds are continuously absent, which may impact the basic demand for convertible bond allocation of low - risk - preference investors such as annuities and disrupt the logic of "tight supply - demand supporting high convertible bond valuations" [22] - The current A - share market valuation is recovering. Large - scale equipment updates and consumer goods trade - in measures are expected to boost domestic demand, while export growth may decline. A weak resonance between the domestic economic fundamentals and the capital market is expected to gradually start. For convertible bonds, considering the impact of refinancing policies, the subsequent issuance pressure is not expected to be high. As the stock market recovers, the return of incremental convertible bond funds drives the valuation to a relatively high historical level, and attention should be paid to the risk of valuation correction. In terms of clauses, attention should be paid to the game space of downward revisions, be vigilant against the forced redemption risk, and appropriately focus on the short - term game opportunities of near - maturity convertible bonds [42] 3. Summary According to the Directory 3.1. Convertible Bond Weekly Special and Outlook 3.1.1. Supply - Demand Structure and Convertible Bond Valuation - Since the fourth quarter of 2023, the new issuance of convertible bonds has significantly declined, while the amount of conversion and maturity has increased. The scale of outstanding convertible bonds has entered a downward channel, with AAA - rated convertible bonds being the main force of contraction. The scale of convertible bonds in industries such as banks, public utilities, environmental protection, and transportation has decreased significantly. As of August 8, 2025, the convertible bond scale has decreased by nearly 70 billion yuan this year [10] - Starting from 2025, the convertible bond market will enter a maturity peak. In 2025, 134 convertible bonds will mature, with an initial issuance scale of 279.3 billion yuan. As of July 31, 2025, 20 of these 134 convertible bonds remain, with a total remaining scale of 48.178 billion yuan. From 2026 to 2028, the theoretical maturity scale of convertible bonds will exceed 200 billion yuan each year. In terms of ratings, from 2025 to 2027, the maturity scale of AAA - rated convertible bonds will be 39.1 billion yuan, 31.3 billion yuan, and 81.8 billion yuan respectively, remaining the main force of future contraction.

The influence of public funds and insurance institutions has increased, while the proportion of enterprise annuities has decreased. Public funds are the main direct investors in convertible bonds, with relatively few restrictions on convertible bond ratings. Pension and insurance institutions usually have clear convertible bond rating restrictions and focus on the safety margin and return certainty of convertible bond prices [21] 3.1.2. Weekly Review and Market Outlook - This week, the market showed an oscillating upward trend, with most of the three major indices rising, but there was differentiation and a slight correction in the second half of the week. The defense, machinery, and non - ferrous metal sectors performed well, while sectors such as commerce and retail, petroleum and petrochemicals, and social services declined [41] - For the stock market outlook, the current A - share market valuation is recovering. Large - scale equipment updates and consumer goods trade - in measures are expected to boost domestic demand, while export growth may decline. A weak resonance between the domestic economic fundamentals and the capital market is expected to gradually start. For convertible bonds, considering the impact of refinancing policies, the subsequent issuance pressure is not expected to be high. As the stock market recovers, the return of incremental convertible bond funds drives the valuation to a relatively high historical level, and attention should be paid to the risk of valuation correction. In terms of clauses, attention should be paid to the game space of downward revisions, be vigilant against the forced redemption risk, and appropriately focus on the short - term game opportunities of near - maturity convertible bonds. Industries to focus on include hot topics, domestic demand - driven sectors, central state - owned enterprises represented by "China -字头", the "Belt and Road" theme, high - dividend sectors, and the military industry [42][43] 3.2.
