SiTime is trading at $487.13, down 4.33%, amid semiconductor-sector pressure.
- No fresh SiTime-specific announcement surfaced for October 22; the October 21 Rosenblatt Buy rating and $750 target were positive, not an apparent explanation.
- SOXX was down 3.64% pre-market as Lam Research fell after its outlook raised concerns about supply constraints and China revenue.
- Broader risk-off sentiment added context, with the Nasdaq Composite down 1.83%; the move supports a sector-led, not company-specific, explanation.
