ASYS is trading 5.7% down at $18.43 after a sharp selloff tied to semiconductor-sector weakness and post-reconstitution volatility.
- Amtech was scheduled to join the Russell 3000 and Russell 2000 indices on June 29, contributing to recent choppy trading and price fluctuations.
- The decline follows a 5.42% drop on June 26; with broader market sentiment remaining positive, the move appears to be stock- and sector-specific.
