Hetzer Medical Indonesia is trading at IDR 81, down 5.81%, as volcanic-ash mask-demand expectations unwind.
- Shares surged 34.72% to IDR 97 on September 7; reports of Anak Krakatau ash moving away weakened mask-demand expectations.
- The company told IDX it knew of no undisclosed material information or planned corporate action explaining the spike.
- Losses extend from IDR 86 on September 11, reflecting earlier volatility rather than a newly disclosed company-specific event; confidence is medium given limited coverage.
