Markets closed. The New York Stock Exchange and Nasdaq observed Juneteenth National Independence Day on Friday, June 19, 2026. There were no settled closes; all book marks below are held at the June 18 settled close and carry a zero day-over-day change. The next pricing edition will cover the Monday, June 22 close.
Week in Review — A three-day AI-beta round trip
The holiday-shortened week was defined by a violent two-way rotation in the AI-beta complex, and the OEF book's behavior through it is the clearest live demonstration to date of the hedge construction working as designed. The sequence: a ceasefire-driven semiconductor selloff on Tuesday and Wednesday, then a sharp snapback Thursday, with the book net range-bound across all three sessions.
Tuesday, June 16 — The prior session's ceasefire euphoria reversed hard. Semis and AI-memory led lower (Micron "MU" −6.2%, Corning "GLW" −5.6%, Intel "INTC" −8.5%), the leveraged-inverse SOXS snapped back, and the book finished essentially flat (+$1.4K) as the structural shorts offset the legacy longs giving back. Book unrealized: +$236.5K.
Wednesday, June 17 — The unwind broadened into megacap tech (Microsoft "MSFT", Meta "META" lower). The book gave back a contained −$5.6K, with the GOES and chokepoint shorts (notably P27 PKX/MT on ArcelorMittal's decline) cushioning the move. Book unrealized: +$231.0K.
Thursday, June 18 — The mirror image: a sharp semi rebound (GLW +11% to $194.92, MU to $1,134, INTC to $134, SOXS collapsing to $3.59). The legacy AI longs led (P1 GLW/MSFT +$24.2K, P28 MU/DELL +$24.0K on the day) while the SOXS-long shorts gave back (P37 −$43.1K, P35 −$25.8K). Net +$8.1K. Book unrealized: +$239.1K.
The three-day net change in unrealized P&L was approximately +$4K on swings that exceeded $40K at the individual-pair level — the shorts carried the down-semi days, the longs carried the up-semi day, and the construction neutralized the rotation. This is the entire point of the book: not to profit from the direction of the AI-beta complex, but to stay solvent and range-bound through its volatility while the structural theses (GOES bottleneck, chokepoint, paper-versus-physical) play out on their own timeline.
Crude and the Macro Backdrop
The week's most durable development was the continued collapse of the crude war premium. With the ceasefire holding and a Strait of Hormuz reopening increasingly priced, West Texas Intermediate spent the week grinding lower toward the mid-$70s. The Paper-versus-Physical ("PvP") thesis is now substantially resolved at the front of the curve — the conflict-closure premium has been wrung out, and crude is once again trading on supply-demand fundamentals rather than geopolitical tail risk. Bonds caught a bid mid-week on the tech growth scare and the oil-driven disinflation impulse.

Book summary (held at June 18 close): Active unrealized +$239,056 across 34 pairs. Realized (frozen): −$82,538. Inception-to-date: +$156,518. Unchanged on the holiday. The book enters the week of June 22 having absorbed a full two-way AI-beta rotation with net P&L intact — the structural shorts and legacy longs continuing to offset one another through volatility while the GOES, chokepoint, and paper-versus-physical theses remain the primary sources of intended directional exposure.
