中金：AH溢价能有多低？

Core Viewpoint - The article discusses the recent significant decline in the AH premium, which has dropped from a peak of 144% in early April to 125% currently, marking a new low since 2020. This decline is attributed to the strong performance of the Hong Kong stock market and the continuous inflow of southbound funds, raising questions about the pricing logic of the AH premium and its future trends [2][20]. Group 1: AH Premium Dynamics - The AH premium arises from differences in investor structure and market mechanisms between the two markets, with the fundamental reason being the existence of arbitrage barriers [3][4]. - The premium is influenced by various factors, including liquidity differences, refinancing systems, trading mechanisms, dividend taxes, and currency exchange rates [4][20]. - Historical data shows that the AH premium has fluctuated significantly across different phases, with the current low being influenced by the performance of the financial sector and the overall market environment [8][9][13]. Group 2: Recent Changes in AH Premium - The recent rapid decline in the AH premium is attributed to three main factors: accelerated inflow of southbound funds, increased attractiveness of dividend-paying stocks, and a wave of quality companies listing in Hong Kong [20][25][29]. - Southbound funds have seen a significant increase, with inflows reaching 9,008 billion HKD this year, surpassing the total for the previous year [20][21]. - The structure of listed companies in Hong Kong has improved due to a surge in IPOs, with many high-quality firms transitioning from A to H shares, enhancing the market's appeal [29][32]. Group 3: Future Outlook of AH Premium - The long-term trend suggests a potential convergence of the AH premium, driven by the continuous attractiveness of dividend stocks and the increasing proportion of southbound funds [37][40]. - However, the premium is unlikely to be completely eliminated due to persistent differences in market mechanisms and investor structures [41][42]. - The current level of 125% is viewed as an "invisible bottom" for the AH premium, serving as a potential timing signal for market movements [42][47].
