JIUYUAN GENE, a biotechnology company, experienced a significant plummet of 33.98% in its stock price during Thursday's intraday trading session, following a disappointing trading debut on the Hong Kong Stock Exchange.

The company's shares opened at HK$7.50, a steep decline of nearly 40% from its initial public offering (IPO) price of HK$12.42. This weak debut performance contributed to the substantial drop in JIUYUAN GENE's stock value.
