Exchange and index data put the technology sector at -3.4% for September 29th, 2026 to October 29th, 2026, with the S&P 500 at 0.4% and XLK trailing the market by -3.8%. Twelve names cleared the FS-01 sale screen in that window, covering $3.11 billion across 2397 filings from 67 filers, and the screen is built on filings rather than on performance.

The backdrop

The October 29th, 2026 Department of Labor print showed the jobless claims four-week average at 197, against 198 previously. A labour market that is still absorbing workers keeps the Federal Reserve in no hurry to ease, and technology valuations that lean on distant cash flows discount at the long end, so steady claims readings hold the discount rate higher than a software or semiconductor multiple would prefer. That mechanism explains why scheduled selling continued even as the sector lost ground against the index.

What would change the view

• The next Jobless Claims 4-Week Average release, measured against the 197 printed on October 29th, 2026 and the 198 before it, would test whether the rate backdrop behind these technology multiples is still steady.
• A fresh Form 4 from Cerebras Systems after the October 27th, 2026 filing, or from CrowdStrike after October 22nd, 2026, would show whether these plans keep executing on schedule or pause.
