On July 3, Hong Kong's biotechnology sector witnessed a general uptick, with notable gains observed across various stocks. Huahao Zhongtian Pharmaceutical led the pack with an increase of over 9%, followed by CStone Pharmaceuticals surging more than 8%, and Ascletis Pharma advancing by more than 7%. Both Kangfang Biotechnology and Top Alliance Biosciences also recorded significant gains, rising by more than 6% each.
