Desk Plan — House Delta — 2026-08-18

Briefing reference: /Users/dadbot/Desktop/ClaudeBod/projects/dadbrain/Analysis/briefings/2026-08-18-pm.md PM: DELTA

Shared Market Read

  • Event risk today: MEDIUM (briefing) — no same-day Tier-1. Import Price Index (8:30) and Home Depot Q2 (pre-market, call 9:00) are the day's scheduled items; neither is in DELTA's hard-skip set (FOMC decision/CPI/NFP/PCE only; VIX ≥ 30). Hard-skip check CLEAR, firm-wide GO — this desk CAN trade. The week's real policy risk is tomorrow's FOMC Minutes (08-19, 2:00 PM) — not a decision, not a skip, and 1 day out; the briefing explicitly warns the desk should not over-commit a one-day direction into it. The live tails are the oil/Hormuz stalemate (Brent ~$91, MOU expired, Trump-Oman threat) and the 30-yr at 2007 highs (~5.31%) pressing on long-duration tech. Import Prices and HD both land before DELTA's 09:30–09:55 measurement window and 10:00 entry — absorbed into the open, not live-position risk.
  • Session character expected: Event-driven / two-tier. Index futures gap lower tech-led — Nasdaq ~-1.1%, S&P ~-0.5%, Dow ~flat — a clean two-tier shape: AI/memory/chips weak, value/Dow defensive. The driver is a fresh AI-valuation wobble in the memory complex (reversal of Monday's Anthropic memory bid; profit-taking/high-valuation nerves, not a demand break). This is the dominant theme and DELTA's exact instrument complex. No clean trending leg is expected; expect a fading-bid or accelerated-sell dynamic in memory/chips into HD's consumer print and the FOMC-Minutes-evened tape.
  • VIX regime: 15.83 — LOW (<18), DELTA's best backtest regime (dev PF 2.59 in VIX < 20 vs. 1.30 in 20–30); the ≥ 30 hard-skip barrier is far away. Supportive; licenses trading — but regime alone does not make the direction.
  • Key levels (DELTA, prior 08-14 closes as the last verified anchor): NVDA 225.16 → +1.5% ≈ 228.5 = clean NVDA→ASML LONG trigger (the high-quality cell, 2W/0L live); −1.5% ≈ 221.8 = disabled SHORT. AMD 514.39 → +1.5% ≈ 522.1 = AMD→TSM LONG trigger (the degraded cell, sub-book n=8, WR 25%, PF 0.191); −1.5% ≈ 506.7 = disabled SHORT. Laggards: ASML ~1,844 (indicative), TSM 426.35. Runner measures actual first-hour returns — authoritative; the cash open will confirm where NVDA/AMD actually gap relative to these anchors.
  • Macro backdrop: Tech is gapping down on AI-valuation nerves against a flat Dow and a consumer-leg focus into the retail-earnings cluster (HD today, TGT/LOW Wed, WMT Thu); oil/Hormuz and the 2007-high 30-yr keep the risk tail live, and FOMC Minutes tomorrow caps any one-day directional conviction.

PRICE-VERIFICATION LIMIT (stated per dispatch): the pm briefing (Alpaca/IEX-verified) carries none of DELTA's four instruments and no consolidated pre-market prints for them. I carry forward the last verified closes (08-14: NVDA 225.16, AMD 514.39, TSM 426.35; ASML ~1,844 indicative) as indicative anchors only — today's cash open and the runner's 09:30–09:55 measurement are the only authoritative signal inputs. On a down-gap tech day, the realized gaps are what matter, and I won't have them until the open.

DELTA — NVDA→ASML, AMD→TSM (LONG-only, Phase 3)

Forecast: p_trade 0.15 | direction long | conviction low

Verdict: the direction bias is against my LONG, and my base case is a disabled-SHORT shadow-book no-trade or a no_signal — not a trade. Yesterday (08-17) semis were the active bid complex and I priced the union at 0.35. Today that complex is the active sell — the AI-valuation wobble is hitting exactly the names whose first-hour +1.5% up-move I'd need to fire a LONG. That inverts the setup I want.

  • Base case (down-semis, shadow): the tech-led gap-down carries NVDA and/or AMD to −1.5% in the first hour → disabled SHORT (structural no-trade under the LONG-only book), logged to the shadow book (AMD_TSM shadow n=8→n=9, or NVDA_ASML's second live disabled-SHORT datapoint after 07-16). This is the most likely real-session path: a tech-down two-tier tape pushes the leaders' first-hour returns negative, and the LONG-only constraint turns that into information, not exposure.
  • Second branch (no_signal): the gap-down is absorbed but the leaders' first-hour |return| stays under ±1.5% (a fading-bid, sub-threshold tape) → no trade (the 07-17/07-20/07-23 pattern). Plausible on a choppy two-tier session; Monday's own no_signal (NVDA +0.08%, AMD −0.51%) shows how often the first-hour impulse just doesn't clear the bar.
  • Third branch (a LONG actually fires — the low-probability reversal): for a LONG I need NVDA or AMD to clear +1.5% up in the first hour — i.e. the memory complex to reverse its gap-down and push a leader up on an AI-valuation-weak tape. That's a genuine contrarian dip-buy scenario (Monday's runners could draw dip-buyers), but it is not the base case today; I price it low. If it does fire, the operative cell question (NVDA→clean vs. AMD→degraded) is the same one I've been carrying: leader identity is the whole game.

Calibration math (day-conditional): P(signal) ≈ 0.45 — semis are the day's dominant theme with real first-hour volatility on a tech-down tape, so an impulse is genuinely more likely than on a dead-flat day. But P(LONG | signal) ≈ 0.35, because the first-hour direction bias is down (disabled), not up — this is the inverse of Monday's 0.55. Net tradable-signal probability ≈ 0.15. Direction long by construction (LONG-only book, and that's the only direction that counts as a real trade). Conviction low: the most probable session outcome is a shadow-book no-trade, and even the LONG branch hands me — with real probability — the chronically-degraded AMD→TSM cell. This is a genuinely low-stakes-stake day.

Sizing vs. event risk: standard 0.75%, single position — no change. No same-day Tier-1; Import Prices and HD both print before my measurement/entry window and are absorbed into the open — no live-position risk. Hard flat 15:30 removes all overnight, so tomorrow's FOMC Minutes is not open exposure (its one-day cap is a conviction caution, not a size cut). The real risk remains cell quality (degraded AMD→TSM firing and losing in a weak tape — the 08-14 loss template), handled by scrutiny and the standing TEMPER gate conversation, not a size cut.

Key levels: NVDA +1.5% ≈ 228.5 → clean NVDA→ASML LONG (2W/0L live, the cell that makes money); NVDA −1.5% ≈ 221.8 → disabled SHORT (shadow). AMD +1.5% ≈ 522.1 → degraded AMD→TSM LONG (sub-book n=8, WR 25%, PF 0.191 — the chronic loser); AMD −1.5% ≈ 506.7 → disabled SHORT (shadow). Laggard cash-open gaps are the second read: ASML (~1,844) / TSM (426.35) gapping with their leader closes the lead-lag spread (late entry); a laggard not gapping is the only genuine lead-lag shape left. But the first read is direction: today the leaders' first-hour move is most likely negative, which maps to a shadow-book no-trade, not a LONG.

Invalidation (stand down entirely):

  • AMD and/or NVDA clears −1.5% in the first hour — disabled SHORT, not a trade; the desk is closed for the day by the LONG-only constraint (the down path is structurally untradeable).
  • SPY or QQQ cash-open gap > 1.5% in either direction — impulse absorbed before measurement; a fresh mid-session >1.5% move against the LONG direction also stands me down.
  • A fresh oil/Hormuz escalation or a 30-yr yield spike that breaks the whole AI complex — the down-gap deepens, no LONG, the reversal branch dies.
  • The memory complex sells through the open and keeps bleeding (profit-taking accelerating, not fading) — confirms no up-impulse; stand down.
  • QQQ turns sharply negative in the first 30 minutes while the complex follows — down-tape confirmed, no LONG.

Information cost (documented, not acted on): a down-semis day remains this desk's structural blind spot — on the most likely real-session path today (AMD/NVDA cascading −1.5%), the disabled SHORT is logged to the shadow book (AMD_TSM n=8→n=9; NVDA_ASML n=1→n=2 if NVDA fires it) but LONG-only keeps costing information in exactly the down-tape an AI-valuation wobble creates. The shadow book is the accounting; the 30-LONG gate (n=10/30 after the 08-14 TSM stop) is the governing SHORT path. The load-bearing continuity thread is the AMD→TSM sub-book — n=8, WR 25%, PF 0.191, three straight losses, tracking at its pre-registered kill switch. Today's down-bias actually protects that book (no AMD up-impulse → no fresh degraded LONG), but if the low-probability up-reversal DOES fire on AMD and loses a fourth straight, the standing TEMPER gate conversation's evidence strengthens, not weakens. NVDA→ASML remains 2W/0L and is the cell whose leadership I most want to see — on a weak AI tape, a surprise NVDA up-clear would be the one genuinely high-quality trade available.

Plan Filed

  • Filed: 2026-08-18 07:45 ET (pre-open, morning dispatch)
  • Frontmatter forecasts complete for every active member: yes
  • Hard skip check: CLEAR (Import Prices/HD are NOT in DELTA's skip set; VIX 15.83 < 30) — firm-wide GO, desk CAN trade. FOMC Minutes tomorrow (08-19) is a conviction caution, not a skip
  • Price-verification limit stated: briefing carries no DELTA-instrument prices; prior 08-14 closes carried forward as indicative anchors (NVDA 225.16, AMD 514.39, TSM 426.35; ASML ~1,844) — the cash open and runner measurement are authoritative
  • Dominant input: the AI-valuation wobble inverts yesterday's setup — tech gaps down, so my base case is a disabled-SHORT shadow-book no-trade (p_trade 0.15); a LONG is the low-probability contrarian reversal, and the degraded AMD→TSM cell is the one I'd most want to avoid
