The Hang Seng Index slipped 0.9 per cent to 23,420.76 at the close of Wednesday trading, reversing an earlier gain of as much as 0.5 per cent. The Tech Index slumped 1.6 per cent, while China’s Shanghai Composite Index declined 0.4 per cent.
WuXi Biologics crashed 19.2 per cent to HK$79.10, the largest one-day drop on record, while Sino Biopharmaceutical tumbled 5 per cent and Innovent Bio lost 9.9 per cent. Tencent and Meituan lost 0.9 per cent and 1.8 per cent respectively, pacing tech losses.
Gains evaporated after the FT said the Treasury Department would sanction eight tech and cloud-computing companies, while the Commerce Department separately would be adding more than two dozen, including unnamed biotechnology companies, to its entity list.
