'Jyong: Technical rebound and short covering after lock-up expiry fueled 34.53% intraday gain'

 

The sharp rise in Jyong Biotech Ltd.'s stock price on December 30, 2025, during regular market hours stems from a technical rebound following intense selling pressure triggered by the mid-December lock-up period expiration. This event unlocked shares held by insiders and early investors, leading to a multi-day price collapse and heightened volatility in the low-float biotech stock. Traders appear to be engaging in short covering and bargain hunting as the stock stabilizes off recent lows around $2.78, amplified by the company's supportive fundamentals like recent Phase II trial enrollment completion. Trading volume spiked alongside the move, reflecting opportunistic positioning in a thinly traded name sensitive to sector flows and year-end dynamics.
