SiTime is trading 4.66% down at $615.00, alongside semiconductor-sector weakness.
- SOXX was down 2.52% during the regular session as concerns about AI spending and macroeconomic pressures from elevated Treasury yields and oil prices weighed on the sector.
- No clear new SiTime-specific announcement explains the decline. Third-quarter results are scheduled for November 4; a Zacks downgrade to Hold was reported as published Monday and does not establish a fresh catalyst for October 9.
