证券研究报告 | 2025年06月29日 转债市场周报 正股高波强势的平衡型品种最具性价比 核心观点 固定收益周报 上周市场焦点（6 月 23 日-6 月 27 日） 上周转债个券多数收涨，中证转债指数全周+2.08%，价格中位数+2.55%， 我们计算的算术平均平价全周+4.54%，全市场转股溢价率与上周相比 -2.67%。个券层面，三羊（汽车物流服务）、奥飞（数据中心）、海泰 （小米汽车概念）、集智（全自动平衡机）、欧通（数据中心电源）转 债涨幅靠前；联得（显示模组设备）、金陵（足球概念）、博瑞（创新 药）、晶瑞（湿电子化学品）、雪榕（食用菌）转债跌幅靠前。 观点及策略（6 月 30 日-7 月 4 日） 转债位置不适合低价类策略，正股高波强势的平衡型品种最具性价比， 若对回撤高要求应降仓而非转至低价： 6 月末上证指数突破前期阻力线再次站上 3400 点，投资者对后市分歧明 显加大。我们认为当前投资者不安感来源于两方面矛盾：1.短期快涨只 能用（已多次被叙述的）长期逻辑解释：中长债持有者因票息太低转向 高股息标的的长期逻辑在 6 月引发银行板块的快速上涨；2.股市方向与 经济现实/预期不匹配：上证指数突 ...
