Holiday edition — U.S. equity markets closed for Juneteenth National Independence Day. No settled prices; the OEF book is carried forward at the June 18 close. Week-in-review. Produced with the Tau Intelligence Engine ("Tau").

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.
