Shares of Star Sports Medicine Co. jumped 204% on their Hong Kong debut, marking a dramatic first‑day rally.

The medical‑device maker opened at a valuation that eclipsed early estimates, sending investors scrambling to secure a stake. The spike reflects heightened appetite for healthcare tech listings in Asia.

Analysts suggest the rally mirrors broader optimism about the region’s medical‑device sector, which has seen robust demand amid aging populations.

The stock’s explosive rise underscores the volatility investors face when new listings enter a market already pacing toward higher valuations.
