Jiangxi Biologics Surges 319% in 20 Days, From IPO Plunge to Record High

According to ZhiTong Finance, Jiangxi Biologics (06915) stock surged from a low of 3.95 HKD on July 9 to 16.55 HKD on July 28, marking a maximum gain of 318.99% within 20 days. The company listed on Hong Kong Stock Exchange on June 30 at an issue price of 11.20 HKD but fell 12.68% on its first trading day, plunging further to a low of 3.95 HKD (down 64.73% from issue price) by July 9.

The sharp rebound started July 10 and accelerated from July 15 amid broader Hong Kong pharmaceutical sector rotation and public fund increased holdings in biotech stocks. However, the stock showed signs of exhaustion on July 28 with volume declining for the second consecutive day and the RSI technical indicator reaching 95.07, signaling overbought conditions alongside net outflows of main force capital.
