(Yicai Global) July 30 -- Shanghai's main stock benchmark was the only one among the three major mainland indexes that gained this morning with the medical sector's continued strong performance.

The Shanghai Composite Index climbed 0.09 percent to 3,297.57. The Shenzhen Component Index was at 13,529.60, down 0.21 percent. The ChiNext Price Index, which tracks growth enterprises in Shenzhen, fell 0.01 percent to 2,767.06.

Two drugmakers that hit the daily 10-percent limit-up were Wantai Biological Pharmacy [SHA:603392] and Da An Gene [SHE:002030]. The first one rose on its upcoming duovirus vaccine cooperation with France's Sanofi Pasteur and the latter on a 10-fold profit increase in the first half due to the booming demand for Covid-19 testing kits.
