PSI is trading 1.93% down at $140.17, pressured by a sharp semiconductor-sector sell-off as investors reassess AI infrastructure financing and returns and worry that CXMT’s memory-chip advances could intensify competition.
- The sector pressure is relevant because PSI is a semiconductor ETF; no clear PSI-specific announcement was identified.
- PSI previously fell 4.28% to $142.93 on October 12.
