Although the convertible bond market meets the pre - conditions for continuous valuation compression, the upward trend of the equity market has not been broken, and the convertible bond premium rate has quickly returned to a relatively reasonable range of 26 - 30%. The convertible bond valuation is expected to continue to fluctuate in the medium and short term [4][28]. - In August, the convertible bond market and underlying stocks rose slightly, and the valuation increased significantly.
