The Week
CIEX.US rallied 27.51% this week to close at $17.14, while the S&P 500 added 1.15%, putting the ETF about 26.36 percentage points ahead of the benchmark.

Sector News
This week’s flow was dominated by AI data-centre interconnect demand and the optical communications theme. Multiple reports highlighted surging AI data-centre interconnect demand and listed US optical communications names to watch. Coverage also zeroed in on Ciena Corp (CIEN), which moved up 11.02% on Oct 6 and 5.55% on Oct 9, mirroring the underlying swings in this ETF. On the insider side, Ciena EVP and Chief Customer Officer Jason Phipps sold 2,629 common shares worth roughly $933,000. Overall, the sector narrative came from the AI data-centre and optical theme, without heavy holdings news dragging the space lower.
The Week Ahead
Next week’s calendar leans on US inflation and real-economy data. On Wednesday, Oct 14, the market gets CPI and core CPI readings; one core CPI measure shows a prior of 2.4 and a forecast of 2.5, while a separate CPI print shows a prior of 3.4 and a forecast of 3.7. If inflation surprises in either direction, rate expectations could reprice. The week also starts with the NFIB small business optimism index and existing home sales. For a 2x daily leveraged ETF, the underlying’s swings get amplified, and volatility typically picks up around inflation releases.
In Short
CIEX.US’s jump this week coincided with heavy attention on AI data-centre interconnect and optical communications, while insider selling offered a counter-detail. On the latest trading day, retail flows were slightly net positive, but that is a single-day snapshot rather than a weekly trend. Standard PE and PB do not apply here, and the very high turnover rate reflects the fast-trading nature of a leveraged product. The key to watch next is how rate expectations shift after the inflation data and whether the underlying can hold its current range near the highs.
