The Hang Seng AH Premium Index has fallen below 120, down from 157.89 in February 2024, narrowing the gap between mainland-listed and Hong Kong-listed shares.
The narrowing gap is evident among hard-technology firms such as Contemporary Amperex Technology Limited (CATL), Montage Technology Co., Ltd., and GigaDevice Semiconductor Co., Ltd.
