I. The Semis Split the Book

On a session in which the desk opened and closed nothing, the book still surrendered −$22,847.67. The cause was not breadth but a split inside a single sector. Nvidia settled at 219.22, up +3.43% on the day; Advanced Micro settled at 482.05, down −7.04%. The Tranche-11 dispersion pairs are built long non-AI-chip beneficiaries against short AI-server names, so that divergence cut both ways at once: it went hard against the three pairs carrying an NVDA short leg — P45 (GNRC/NVDA), P48 (MU/NVDA) and P52 (GLW/NVDA), a combined −$13,458.63 — while the AMD short in P54 (GLW/AMD) made it the day's second-best pair at +$5,175.39. One complex, two directions, and the short-NVDA concentration is what set the day's tone.

II. The Session

Thirty-seven active pairs, no trades. Active unrealized deepened from −$115,789.93 at the 8/4 close to −$138,631.16, a mark-to-market swing that is the mirror image of the day’s −$22,847.67 book P&L. The realized register is unchanged and frozen at +$547,595.36 across 17 closed pairs; inception-to-date stands at $408,964.20. Concentration is where the risk lived today: GNRC is long on six active pairs and GLW long on five, while NVDA is short on three — and it was that three-pair NVDA short, not the six-pair Generac long, that did the damage.

III. The NVDA Short Legs

Nvidia has now closed at 219.22 with a Wilder RSI-14 of 63 — firm, not yet stretched. The book is short the name on three pairs. P52 (long GLW / short NVDA) was the worst pair of the day at −$5,500.99, hit on both legs as Corning fell −2.00% to 156.70 while Nvidia rose. P45 (long GNRC / short NVDA) lost −$4,322.84 and P48 (long MU / short NVDA) −$3,634.80. These are the optical-interconnect and memory dispersion trades carried over from the 8/4 optical-transceiver thesis; the thesis is intact, but a rising Nvidia is the single largest live risk to it.

IV. AMD’s Break, and the Other Side of the Trade

The same structural bet paid on the other chip. AMD fell −7.04% to 482.05 (RSI-14 of 47), and P54 (long GLW / short AMD) returned +$5,175.39 — enough to rank second on the day despite the shared, sagging Corning long. The split is the point: the book’s AI-server shorts are not a single position but a basket, and on 8/5 the basket disagreed with itself. That is the argument for keeping the dispersion diversified across NVDA, AMD, DELL and META shorts rather than concentrating in one name.

V. Corning, Generac, and the Carried Theses

The two long anchors of the Tranche-11 book both softened. Corning (GLW), long on five pairs, settled −2.00% to 156.70; Generac (GNRC), long on six, eased −0.56% to 217.41. Neither move was violent, but with eleven combined long legs between them, small declines add up — and they compounded the NVDA-short pain on P45 and P52 specifically, where a falling long met a rising short. The optical-transceiver and data-center-backlog theses that opened these pairs on 8/4 remain in place; nothing in the 8/5 tape changed them, but the book is now carrying them at a wider unrealized loss.

VI. What Worked

The day was not one-sided. P12 (long MET / short CVS) was the single best pair at +$7,754.98, driven by a roughly 5% decline in CVS (RSI-14 of 37, the book’s weakest short-leg reading). P15 (long FCX / short APTV) added +$4,346.26 as Aptiv extended the guidance-driven weakness first flagged on 8/4 (RSI-14 of 25). P4 (long XYL / short RONB) returned +$4,132.84, and the steel/industrials dispersion in P25 (CLF/NUE) and P31 (XME/DAL) contributed a further +$2,966.16 and +$2,795.50. Tranche 2 as a whole was the day’s best cohort at +$6,830.01.

VII. Tranche-Level Summary

Tranche 11, the newest and largest cohort, was also the day’s worst at −$11,060.05 — the direct footprint of the NVDA-short concentration described above. Tranches 2 and 5 were the only cohorts in the green.

VIII. What to Watch

First, Nvidia’s momentum: at an RSI of 63 with three short legs against it, any further run widens the book’s largest live loss, while a reversal would relieve P45, P48 and P52 at once. Second, whether AMD’s 7% break extends — P54 is the clean beneficiary. Third, the Corning and Generac longs: eleven combined legs mean the book is directionally long both names whether or not any single pair says so, and today showed how small declines there compound. Finally, a coverage note rather than a market one: MURGY and ICAGY, the short legs on P11 and P33, are OTC ADRs with no reachable daily price history, so their RSI-14 cells read n/a this edition; their marks are book-confirmed, only the momentum reading is unavailable.

IX. The Book

Thirty-seven active pairs, marked to the 2026-08-05 settled close, sorted by day P&L. Long leg stacked above short in every per-leg column; Day %Δ is each ticker’s move versus the 8/4 settled close, % Entry is from the pair’s inception price, and RSI-14 is Wilder as of the 8/5 close.

X. Provenance

Marks are the 2026-08-05 settled close (Mode A), two-source confirmed to the cent across all 56 distinct tickers spanning the 74 active legs, per the 2026-08-05 canonical v14 book of record. Day changes are computed against the 2026-08-04 settled close taken from the 8/4 v4 settled-close edition. Per-pair unrealized and day P&L are the book’s figures; an independent recomputation from share counts and price moves reconciles all 37 pairs to the cent bar a $12 rounding artifact on P3. RSI-14 is Wilder’s 14-period, recomputed for this edition from ~30 sessions of daily closes per ticker pulled from stockanalysis.com, with each series validated so its 2026-08-04 close matched the book anchor and its 8/4 and 8/5 endpoints forced to the book’s confirmed marks; NVDA was independently cross-checked (63.2). MURGY and ICAGY are OTC ADRs with no reachable daily history and are shown n/a. No pairs opened or closed on 2026-08-05. This edition asserts no new external market-news claims for the session; the narrative is derived from the book’s verified price action and from theses previously sourced in the 2026-08-04 edition (the optical-transceiver / data-center complex and the Aptiv dispersion pair).
