The CXO sector in the Hong Kong stock market collectively rose, with Wuxi Bio and Wuxi Apptec both up more than 4%, Tigermed up 3%, Asymchem Laboratories, Pharmaron, and Jinsirui up more than 2%. The U.S. House of Representatives recently passed the Biodefense Act by 306 votes to 81 votes, which will be submitted to the Senate next. Citigroup's latest report points out that while it is unclear whether the U.S. Senate will adopt the House version of the Biodefense Act or another version, or attach a larger bill to the Biodefense Act. The bank believes that the stock prices of Wuxi Apptec and Wuxi Bio are undervalued, but the uncertainty is affecting investors' confidence in the CXO sector.
