The Hang Seng AH Premium Index has hit a five-year low, with some companies experiencing an "H-share premium" phenomenon.

Since the beginning of this year, the overall performance of the Hong Kong stock index has been strong, outperforming major global stock indices during the same period, while the Hang Seng AH premium index has been continuously declining. On June 12, the index hit a low of 126.91 points, the lowest since June 2020. As of the close on June 13, the Hang Seng AH premium index reported 128.05 points, with a overall decrease of more than 10% since the beginning of the year. It has always been a common phenomenon for A shares to have a premium over H shares, with 42 companies still having a premium rate of over 100%. At the same time, companies with H shares trading at a premium to A shares are becoming more common, such as Ningde Times, Sino Biopharmaceutical, and China Merchants Bank. Many industry insiders believe that the AH price difference may continue to narrow in the short term, and the current changes may indicate the beginning of a new long-term trend.
