The Week
Invesco Semiconductors ETF (PSI.US) closed the week at $149.32, down 7.22% from the prior Friday’s close of $160.94. The S&P 500 rose 1.15% over the same stretch, leaving the fund about 8.37 percentage points behind the benchmark. Day to day, Monday opened slightly lower and held the $160 level, Tuesday pushed to a high of $162.05 before fading, and Wednesday gapped down to $154.55. The next two sessions tested support near $148, with Friday ending near the week’s low — a pattern of early strength giving way to a lower centre of gravity. Weekly amplitude was 8.76%, and average daily volume of about 547k shares ran 81.6% above the 301k median, pointing to heavier-than-usual turnover.
Sector News
Semiconductors took broad pressure this week as AI-linked sentiment weakened. On 9 October, reports that OpenAI’s revenue was $20 billion below earlier figures hit Oracle, Nvidia and other AI names, making it the week’s clearest sector-level headwind. Insider selling also clustered across the group: Analog Devices’ chair and CEO disposed of 10,000 shares, while its CFO and chief operations/technology officer also filed sales. Semtech’s CEO and its CCO both reported disposals. Applied Materials, KLA and Texas Instruments saw active trading; Texas Instruments was flagged twice as underperforming competitors on Wednesday and Friday. Micron disclosed fiscal 2026 revenue of $133.19 billion and reports pointed to a $35 billion buyback effective December, but that did not lift the broader tape.
The Week Ahead
The front half of next week brings US CPI and core CPI on 14 October, with the core print’s move from the prior 2.4% closely watched for the rate path. NFIB small business optimism and existing home sales land on 13 October. On the earnings front, semiconductor equipment and chipmakers are entering a busy disclosure stretch; Cramer’s weekend preview flagged banks and chipmakers as facing big tests. Also worth tracking: whether AI sentiment stabilises after this week’s OpenAI revenue scare, and how Micron trades into its December buyback.
In Short
PSI.US fell while the S&P 500 rose, showing the sector’s sensitivity to AI revenue expectations once more. On one side, the fund still sits above its 20-day moving average of $147.15 and 60-day of $142.84, so the medium-term structure is intact. On the other, dense insider selling and softer AI headlines leave limited rebound momentum. The latest session’s flow showed large lots as net sellers and small lots as net buyers, with no clear single direction. The key question now is whether next week’s CPI keeps rate expectations steady, and whether chipmakers’ guidance in earnings season is strong enough to carry current valuations.
