1. Report Industry Investment Rating No investment rating for the industry is provided in the report. 2. Core Viewpoints of the Report - Risk preference recovery and the strengthening of the equity nature in the convertible bond market suggest that the liquidity style is expected to strengthen again. The convertible bond market has entered the "high-beta stage of a slow bull market", with the pricing logic shifting from "bond defense" to "equity elasticity". The liquidity factor is expected to strengthen once more [1]. - In the short - term, as the global market's expectation of recent liquidity tightness eases marginally, the correction space of the convertible bond market with sufficient incremental funds may be limited. Under the slow - bull expectation, the equity market's spring rally is in the making, and the convertible bond market still has structural opportunities [2][11]. - In the medium - term, the marginal improvement in liquidity and market structural characteristics highlight the allocation value of the liquidity style. The liquidity factor is expected to shift from "steady contribution" to "strong performance" [3][18]. - In the long - term, the convertible bond market shows obvious liquidity premium. The liquidity style has the best performance under a market - neutral condition [4][12]. 3.
