The Week
XSD.US closed the week at $527.93, down 4.91%, while the S&P 500 gained 1.15%, leaving the ETF about 6.06 percentage points behind. The week shaped up as a failed rally. It opened near $554.55 on Monday, hit the week’s high of $562.19 on Tuesday, then broke lower. Thursday’s loss was the heaviest, with volume surging as the ETF fell toward $520.69; Friday traded in a low range and finished at $527.93. Weekly amplitude was 7.67%, and average daily volume of 117,937 shares ran about 33% above the prior median.
Sector News
Semiconductor news this week revolved around AI infrastructure and high-speed connectivity. Penguin Solutions reported Q4 revenue up 68% year-on-year and lifted its FY2027 net sales midpoint to $2.43 billion, prompting several analysts to raise estimates; Rosenblatt kept a buy rating with a $100 target. Marvell received a wave of post-investor-day upgrades. Astera Labs unveiled PCIe 7 connectivity chips at the OCP Global Summit. Optical stocks diverged: Lumentum said component capacity is sold out through 2029 and rallied over 4%, while Coherent and Credo faced pre-market pressure. On Friday, OpenAI’s lowered revenue outlook dragged AI names broadly lower, with Oracle and Nvidia retreating alongside.
The Week Ahead
The macro focus next week is inflation. US CPI and core CPI are due on Wednesday 14 October; core CPI is forecast at 2.5% versus 2.4% prior, and headline CPI at 3.7% versus 3.4% prior. Those prints will test sentiment in rate-sensitive growth segments like semiconductors. Tuesday 13 October brings NFIB small business optimism and existing home sales. After Monday’s close, Monolithic Power reports Q3 2026 results, and its guidance could serve as a reference point for the broader chip supply chain.
In Short
XSD.US spent the week caught between sector-specific strength and macro unease. Penguin Solutions’ beat, Marvell’s upgrades and Astera Labs’ new PCIe 7 chips pointed upward, but OpenAI’s revenue gap and Friday’s AI sell-off pulled the group back, even as the S&P 500 advanced. Valuation offers little comfort: the ETF trades around 3.15x book value while its earnings remain negative, so P/E has no positive read. The tension to resolve next week is whether the 14 October CPI print reinforces or relieves pressure on rate-sensitive growth stocks, and whether Monolithic Power’s results give the sector a fresh anchor.
