SEMI is trading 1.59% lower at $39.03 in pre-market, with the cause unclear.
- The Columbia Select Technology ETF closed at $39.66 on September 24.
- No credible September 25 company-specific announcement, earnings release, or filing explains the decline. The Sanders superintelligence proposal, announced September 3, is stale and insufficient as a direct catalyst.
- The move appears isolated despite firmer broader-market futures.
