COHH is trading at $3.43, down 3.79% versus the regular-session close, with Coherent’s after-hours weakness a likely direct driver.
- COHH targets 2× daily exposure to Coherent, so weakness in COHR can translate into a larger ETF move.
- Coherent was down 1.46% after hours at 6:27 p.m. EDT.
- Regular-session AI-infrastructure optimism, supported by SpaceX results and Super Micro’s stronger outlook, does not explain the later reversal; no specific new Coherent catalyst for the post-close drop was verified.
