Desk Plan — House Delta — 2026-07-28

Briefing reference: /Users/dadbot/Desktop/ClaudeBod/projects/dadbrain/Analysis/briefings/2026-07-28-pm.md PM: DELTA

Shared Market Read

  • Event risk today: HIGH — FOMC tomorrow (Wed July 29, rate decision + press conference 2:00 PM ET). PCE July 30 (Thu). The 28-35% hike probability (up from 12% a week ago) creates binary risk for any position held through Wednesday's close.
  • Session character expected: Event-driven / two-sided. The AI/semi rout continuation from Monday is the morning driver. Consumer Confidence (10:00 AM ET) is the only macro data — lands at DELTA's entry window. Pre-FOMC positioning dominates the afternoon. The two-tier divergence (Dow futures +0.25%, Nasdaq futures -0.89%) is the dominant structure.
  • VIX regime: 19.02 (MID — 18-28). Just crossed into MID from yesterday's LOW (17.57). DELTA's backtest edge is present in MID regimes, but the jump from LOW to MID signals the regime transition from ceasefire relief to AI/semi rout anxiety.
  • Key levels: NVDA prior close ~$108.50 (gapped down from $113.48 prior). NVDA pre-market +0.64%. AMD prior close ~$140 (gapped down from ~$147), pre-market +1.97%. ASML prior close (Euronext) reflected -8.5% Monday — structural China lithography overhang. QQQ below SMA20 at 710.45 (price ~682).
  • Macro backdrop: AI anxiety deepens into a global tech rout. Two catalysts: WSJ NVDA-OpenAI $250B financing guarantee and China domestic immersion DUV lithography challenging ASML's monopoly. KOSPI circuit breaker — worst monthly fall on record. Oil continues to consolidate lower (WTI $81.02, -1.92%) on US-Iran ceasefire. Pre-FOMC positioning overhangs everything.

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

Setup present: Possible but unlikely (~15-20% probability). Key considerations:

What's favorable:

  1. Semi-specific catalyst dominates. The NVDA/OpenAI financing story and China lithography challenge are supply-chain-specific narratives — exactly the kind of information that propagates through the NVDA→ASML and AMD→TSM lead-lag channels. Unlike yesterday's broad ceasefire relief rally (which was macro-driven), today's catalyst is semiconductor-specific. If the leader moves, it's more likely driven by substantive supply-chain repricing.
  2. Pre-market bounce after a -4.5%/-5% day. NVDA +0.64% and AMD +1.97% pre-market after Monday's rout. AMD at +1.97% is particularly notable — if the bounce carries into the cash session, the +1.5% first-hour gate is within reach. A recovery bounce in a supply-chain-relevant catalyst context has a higher probability of persistence than a purely macro-driven bounce.
  3. VIX at 19.02 (MID regime) is tradeable. The strategy has no VIX hard skip below 30. The LOW (sub-18) to MID transition is manageable — the edge does not require VIX to be single-digit low.
  4. No hard skip today. FOMC is TOMORROW, not today. The strategy's hard skip rule (FOMC/CPI/NFP/PCE days) does not trigger for today's session. The 15:30 hard flat exit protects against overnight risk into the FOMC decision.

What's unfavorable:

  1. FOMC-eve positioning creates noise. Even though it's not a hard-skip day, the session character on the eve of a Tier-1 event (especially one with 28-35% hike probability) is fundamentally different from a normal session. Pre-positioning, reduced institutional conviction, and headline-sensitivity all reduce the signal-to-noise ratio. The lead-lag relationship is cleaner on non-FOMC-neutral sessions. The Consumer Confidence print at 10:00 AM — landing exactly at DELTA's entry window — adds further data-event noise at the exact moment the laggard entry executes.
  2. The dominant Monday direction was DOWN. NVDA -4.5%, AMD -5%, ASML -8.5%. The AI/semi rout is a SHORT-direction story. DELTA is LONG-only. If the bounce fizzles and the selling resumes (SHORT signals fire on NVDA/AMD), those signals are untradeable. The TEMPER 2026-07-24 learning (SHORT shadow-book recommendation) is directly relevant here: in a sustained semi bear market, LONG signals decline in frequency while SHORT signals become regime-aligned. Today is a live example of this structural asymmetry.
  3. AMD→TSM sub-book concern. n=4, WR 25%, PF 0.251 — near the pre-registered kill-switch boundary. If AMD fires as the leader (pre-market +1.97% makes it the more likely candidate), the resulting trade would be AMD→TSM — the structurally compromised pair. The 2026-07-27 plan explicitly stated "any AMD→TSM signal today will be logged but not traded." This concern carries forward. A NVDA→ASML signal is strongly preferred but less likely given NVDA's weaker pre-market (+0.64% vs AMD's +1.97%).
  4. ASML European session contamination. ASML's Euronext session has already repriced -8.5% on Monday. The China lithography news was absorbed in European hours. By the time the NVDA→ASML pair is evaluated at 09:55 ET, the lead-lag gap from Monday's NVDA move has already been at least partially expressed in ASML. For a NEW NVDA move today (a bounce), ASML hasn't moved yet in US hours, so the lead-lag gap for a LONG signal (NVDA up → ASML up) could still be valid. But the structural China overhang means ASML may be resistant to following NVDA higher.
  5. SPRT is near zero — LLR -0.079, CONTINUE. The SPRT gives no strong directional signal. The book is essentially flat at n=5 (2W/3L). This is not in itself a reason to stand down, but it means there is no accumulated evidence that the strategy is performing above the null. Each new trade carries full weight.

Session-character fit: LOW-MEDIUM. The AI/semi rout is the correct catalyst family for DELTA's edge, and a bounce on a semi-specific catalyst is structurally better than a macro-driven bounce. However, FOMC-eve noise, the LONG-only constraint in a down-trending sector, and the AMD→TSM sub-book concern make this a challenging day. The probability of a clean NVDA→ASML LONG signal (preferred pair) is approximately 10-15%. The probability of an AMD→TSM LONG signal (compromised pair, potentially untradeable) is approximately 15-20% given AMD's strong pre-market.

Key math:

  • NVDA: Prior close ~$108.50. Pre-market +0.64% → ~$109.20 open. Needs to reach ~$110.85 by 09:55 for +1.5% from open. A ~$1.65 move in 25 minutes on a bounce day after -4.5%. Possible but requires conviction.
  • AMD: Prior close ~$140. Pre-market +1.97% → ~$142.76 open. Needs to reach ~$144.90 by 09:55 for +1.5% from open. A ~$2.14 move in 25 minutes on a bounce day after -5%. AMD's pre-market strength makes this more plausible than NVDA.
  • ASML (laggard for NVDA): Euronext closed ~-8.5% Monday. US ADR gap open likely reflects the same. For a LONG trade, we buy ASML at 10:00 ET if NVDA fires. The structural China overhang means ASML may not follow NVDA higher — the lead-lag relationship may be asymmetric in a bearish semi environment.
  • TSM ADR (laggard for AMD): TSM was -2.3% Monday. Less damaged than ASML. The AMD→TSM supply chain is more tightly coupled (chip design → foundry) than NVDA→ASML (chipmaker → lithography equipment). But the sub-book is the constraint.

Invalidation:

  1. Neither NVDA nor AMD produces a first-hour |return| ≥ 1.5% (most likely outcome, ~75-80%).
  2. The bounce fizzles early — NVDA/AMD open, spike briefly, then reverse red within the first 30 minutes. This confirms SHORT signals (untradeable) and eliminates the LONG path.
  3. VIX ticks up toward 20+ during the first hour, confirming the fear premium is reasserting.
  4. Only AMD→TSM fires and the NVDA→ASML pair does not — tradeability depends on desk PM's judgment on whether the sub-book concern warrants a skip. Based on 2026-07-27 precedent, AMD→TSM should be logged but not traded.
  5. Consumer Confidence (10:00 AM) print is a major miss/beat that dominates the entry bar, contaminating the clean lead-lag entry.

Sizing: Standard 0.75% per trade IF:

  • The signal is NVDA→ASML (preferred pair, 1.85 combined PF)

OR

  • The signal is AMD→TSM AND the SPRT sub-book condition is re-evaluated at entry time (judgment call — sub-book at n=4, WR 25% is borderline; 2026-07-27 precedent was to log but not trade)

If an AMD→TSM trade is taken, consideration should be given to reducing size to 0.5% given the sub-book risk.

Forecast rationale: p_trade=0.15. The semi-specific catalyst family (NVDA/OpenAI, China lithography) is the right backdrop for DELTA's edge, and a bounce after -4.5%/-5% creates the most natural path to a LONG signal this month. But FOMC-eve noise, the LONG-only constraint in a bearish sector, Consumer Confidence at 10:00 AM, and the AMD→TSM sub-book concern all converge to keep the probability low. NVDA→ASML is the only clean path, and NVDA's pre-market (+0.64%) is too weak to confidently predict a +1.5% first-hour gate crossing.
