1. Report Industry Investment Rating There is no information provided in the document about the industry investment rating. 2. Core Viewpoints of the Report - The recent intense compression of convertible bond valuations is a recurrence of historical patterns. The early spring rally in the stock market synchronized with changes in convertible bond capital flows, amplifying the amplitude of valuations and the convertible bond index [1][11]. - The decline in convertible bond valuations shows significant structural differences. In terms of the parity structure, the valuations of debt - biased and balanced bonds remain high, while those of equity - biased and high - price bonds have fallen back to around early January. In terms of the term structure, the valuations of newly - issued bonds have dropped significantly, and those of near - maturity bonds have also adjusted notably [2][13][16]. - Looking at historical experiences of significant valuation compressions, the end of convertible bond valuation compression is almost synchronous with the stabilization of equities. When convertible bond valuations fall from high levels, the first rebound of equities does not strongly drive up convertible bond valuations, and a stronger equity expectation is needed for valuation recovery. If the equity rebound is weak or in a volatile state, convertible bond valuations may continue to adjust slowly [3][19][27]. - In the future, the overall position should be adjusted to a neutral position, waiting for equity stabilization signals. In terms of the term structure, although the valuations of newly - issued bonds have declined, they are still at a historically high level, and more caution is needed. In terms of the parity structure, debt - biased or balanced convertible bonds may face greater downward pressure, while equity - biased convertible bonds with a parity between 110 - 130 yuan have seen their risk - return ratios improve, and more attention can be paid to elastic varieties if the equity market is expected to perform well [4][38]. 3. Summary by Relevant Catalogs I. Decomposition of the Decline in Convertible Bond Valuations and Historical References (1) Question 1: Why has the convertible bond valuation compressed so intensely recently? - The pre - Spring Festival rush to allocate convertible bonds pushed valuations to new highs, but after the festival, it entered a profit - taking window, and valuations generally compressed. In 2026, the early spring rally in the stock market synchronized with changes in convertible bond capital flows, amplifying the amplitude of this adjustment [11]. - The net subscription and redemption intensities of "fixed - income +" funds and convertible bond ETFs also confirm this view. There were significant net subscriptions before the Spring Festival, indicating an influx of allocation funds, and after a brief shock, there was a large - scale shift to net redemptions in early March, indicating that profit - taking demand dominated [11]. (2) Question 2: What are the structural characteristics of this round of valuation compression? - **Parity Structure**: Debt - biased and balanced bonds maintained high levels, while equity - biased and high - price bonds fell back to around early January. The 70 - 90 parity bonds adjusted the least, the 90 - 110 parity bonds adjusted moderately, and the 110 - 130 parity bonds adjusted most significantly. High - parity bonds (parity > 130 yuan) and high - price bonds (price > 160 yuan) also saw notable declines [13]. - **Term Structure**: The valuations of newly - issued bonds (listed for less than 1 year) dropped significantly, and those of near - maturity bonds (remaining term less than 1 year) also adjusted notably. The valuation difference between new and old bonds has converged but is still at a historical high [16]. (3) Question 3: What can be learned from historical valuation compressions? - There have been 8 historical periods with valuation adjustments lasting over 1 month and compression amplitudes greater than 5 pcts. After excluding periods with irrelevant influencing factors, the following experiences can be learned: the end of convertible bond valuation compression is almost synchronous with the stabilization of equities; when convertible bond valuations fall from high levels, the first rebound of equities does not strongly drive up convertible bond valuations; if the equity rebound is weak or in a volatile state, convertible bond valuations may continue to adjust slowly [19][27]. II. Convertible Bond Strategy: Wait and See for Position Restoration, Focus on Elasticity in Structure - Affected by factors such as inflation, tightened global liquidity, economic recession expectations, and supply chain disruptions caused by the long - term US - Iran war, the A - share market has adjusted significantly, especially the previously leading oil - alternative energy and related industrial chain concepts [31]. - In the future, as the impact of geopolitical conflicts reaches a climax, it is recommended to focus on trading thinking. Industries with "self - dominated" prosperity characteristics in the technology and growth sectors can be focused on, and short - term valuation repair opportunities in low - risk sectors can also be appropriately considered [31]. - The overall position should be adjusted to a neutral position, waiting for equity stabilization signals. In terms of the term structure, although the valuations of newly - issued bonds have declined, they are still at a historically high level, and more caution is needed. In terms of the parity structure, debt - biased or balanced convertible bonds may face greater downward pressure, while equity - biased convertible bonds with a parity between 110 - 130 yuan have seen their risk - return ratios improve, and more attention can be paid to elastic varieties if the equity market is expected to perform well [38].

Core Viewpoint - The article highlights concerns regarding the use of anesthetics in live fish transportation, particularly the use of substances like eugenol and industrial alcohol, which pose health risks to consumers [1][3][10]. Group 1: Anesthetic Use in Fish Transportation - Reports indicate that various fish markets in China, including those in Chongqing, Shandong, and Anhui, have been found using eugenol and other substances to induce a "sleeping" state in live fish [1][4]. - In the Chongqing Lebang Aquatic Market, long-distance transported fish often appear in a "sleeping" state, which is confirmed to be due to human intervention rather than natural behavior [4][6]. - Workers were observed adding eugenol-containing products, labeled as "Fish Protector," to fish transport containers, which lack production dates and licenses, raising significant safety concerns [6][10].
