Core Viewpoint - The convertible bond market in 2025 is characterized by a significant "exit wave" driven by both "asset scarcity" and structural trends in the equity market, leading to a contraction in scale and localized surges in activity [1][3]. Group 1: Market Exit Trends - As of December 23, 2025, a total of 173 convertible bonds are expected to exit the market, a substantial increase from 88 in 2024, marking an increase of 85 bonds, nearly doubling the previous year's figure [3][4]. - The exit scale, calculated based on the fundraising amounts at issuance, is projected to reach 320.8 billion yuan in 2025, compared to 110.5 billion yuan in 2024, representing an increase of 210.3 billion yuan, also nearly doubling [3][4]. Group 2: Characteristics of Exits - Among the 173 convertible bonds exiting this year, 134 (77.46%) are doing so through forced redemption, a significant rise from 57.95% in 2024, indicating a trend towards more issuers exercising this option [6]. - The collective exit of bank convertible bonds, including notable ones like the浦发转债 with a 50 billion yuan issuance scale, has become a hallmark of this exit wave [5]. Group 3: Market Scale and Supply-Demand Dynamics - The total number of outstanding convertible bonds has decreased by 116 to 413, with the total market size shrinking by approximately 175.97 billion yuan to around 557.76 billion yuan [8][9]. - The issuance of new convertible bonds has not compensated for the exits, with only 48 new bonds issued in 2025, totaling 63.98 billion yuan, which is insufficient to offset the market contraction [9]. Group 4: Valuation and Investment Strategy - The convertible bond market is experiencing high valuation levels, with a median price exceeding 131 yuan and a median conversion premium over 32%, indicating a market in a "high valuation, low yield" state [12]. - Investors are advised to reduce exposure to high-priced, high-premium equity-type convertible bonds while focusing on those with higher yield-to-maturity and stable underlying stocks, which can provide some protection and opportunities for adjustment [13][14].

家电行业的"铝代铜"之争引发热议。12月22日，中国家用电器协会表示，应理性看待"铝代铜"。争议背 后，是铜价持续上涨推动空调等相关产品制造成本攀升。 当前，美国借助纽约COMEX交易所的超高溢价，对全球现货铜形成强烈虹吸效应，已"锁住"72万吨的 铜超额库存。机构预计，美国所需的超额库存储备规模或达160万—180万吨，缺口约达100万吨。 这种背景下，国内"铝代铜"的紧迫性明显提升。值得注意的是，今年在传统工业需求疲软的背景下， LME铝价已经逆势攀升至3年高位，沪铝期货主力合约亦突破近三年高位。业内人士认为，在铜铝替代 效应下，铝仍有巨大的补涨潜力。 中国家用电器协会：理性看待"铝代铜" 对于空调行业的"铝代铜"之争，有了正式回应。12月22日，中国家用电器协会发文表示，真正的行业进 步，不是在"铜"与"铝"之间做简单取舍，而是在保障品质、尊重用户与服务国家战略之间找到最优解。 从纽约COMEX和伦敦LME两大市场的跨市价差水平上看，当前美国仍在维持对全球金属铜的虹吸效 应，11月下旬以来COMEX-LME价差逐步抬升至4%—5%的位置，从曲线结构来看，COMEX铜维持远 期陡峭的升水结构。价差与结构共 ...

1. Report Industry Investment Rating - No information provided in the document. 2. Core Viewpoints of the Report - For copper, the long - term TC for copper concentrate is set at $0/ton next year, with little impact on the market. The domestic market may see a slight inventory build - up until the Spring Festival. With loose overseas liquidity, copper prices should be bought on dips, with an expected price range of $10,800 - $12,000 in December [1]. - For aluminum, although domestic demand is weak, the decreasing inventory supports the price, and it is expected to remain in a volatile range [1]. - For zinc, the domestic fundamentals are poor, but there may be a phased reduction in supply at the end of the year. It is recommended to wait and see for single - side trading, focus on reverse arbitrage opportunities between domestic and overseas markets, and positive arbitrage opportunities for 01 - 03 and 03 - 05 spreads [6]. - For nickel, the short - term fundamentals are weak, but the policy side has a motivation to support prices, leading to intensified policy - fundamentals game [10]. - For stainless steel, the fundamentals are weak, but the news of quota reduction from the Indonesian Nickel Association drives a short - term price rebound [12]. - For lead, the price is expected to oscillate between 16,700 - 17,100 yuan, and attention should be paid to the risk of low warehouse receipts [15]. - For tin, the short - term fundamentals show signs of weakening, and there is a risk of supply over - increase. In the long - term, demand determines the upside space [18]. - For industrial silicon, in the short - term, the supply and demand are balanced, and the price will fluctuate with costs. In the long - term, it will oscillate at the cycle bottom [19]. - For lithium carbonate, the current supply and demand are both strong, but demand shows signs of weakening. The price needs further inventory reduction, speculative demand, or stronger holding willingness to rise [21]. 3.
