The Tape — Semis snap back, the unwind reverses
After two sessions of relentless AI-beta selling, Thursday delivered the snapback. Semiconductors and AI-memory led a sharp recovery: Corning ("GLW") exploded higher to $194.92 — an 11% single-session move — Micron ("MU") ripped to $1,133.99, Intel ("INTC") surged to $133.99, Broadcom ("AVGO") jumped to $411.35, and AMD climbed to $537.37. The leveraged-inverse SOXS collapsed to $3.59 as the semi complex roared back.
This was a mirror image of Tuesday and Wednesday. The crowded AI-infrastructure longs that had bled for two days found aggressive buyers, and the rotation that had favored defensives reversed. GE Vernova ("GEV") continued its remarkable run to $1,109.73 and the Korea proxy (EWY) jumped to $219.20. The move had the character of a violent short-cover and dip-buy after an overextended two-day washout rather than a fundamental regime change.
Crude remained the structural anchor: West Texas Intermediate held its lower range as the ceasefire and Strait of Hormuz normalization stayed priced. The Paper-versus-Physical ("PvP") thesis is now largely resolved at the front of the curve — the war premium has been wrung out, and crude is trading on supply-demand fundamentals again rather than conflict tail risk.

Book summary (June 18 close): Active unrealized +$239,056 across 34 pairs (June 17: +$230,955; day +$8,102). Realized (frozen): −$82,538. Inception-to-date: +$156,518. The mirror of the prior two sessions: on a sharp semi rebound the legacy AI-beta longs led — P1 GLW/MSFT (+$24.2K day), P28 MU/DELL (+$24.0K), P13 (+$15.0K), P6 (+$12.7K) — while the SOXS-long structural shorts gave back as the inverse cratered: P37 SOXS/AVGO (−$43.1K) and P35 SOXS/INTC (−$25.8K), with T8 Semi-short to −$65.8K. Net +$8.1K on the day. This is the book's designed symmetry on display across the full three-day round trip: the shorts carried the down-semi days (June 16–17), the longs carried the up-semi day (June 18), and the net stayed range-bound through a violent two-way rotation.
