Despite the derating of Chinese CXO companies in 2021, we still remain positive on the sector, because of a) high technical barriers, resulting in a strong Matthew effect and making it easier for leading companies to expand their business; b) resilient global demand for CXO services; c) strong 2021 financial results, indicating strong business growth capability, d) the low valuation of China CXO companies, presenting bottom-fishing opportunities, and e) higher overseas exposure of names such as Wuxi Biologics and Wuxi Apptec, making them more immune to potential pressure from China policies.
