Desk Plan — House Vesper — 2026-07-29

Briefing reference: /Users/dadbot/Desktop/ClaudeBod/projects/dadbrain/Analysis/briefings/2026-07-29-pm.md PM: VESPER

Shared Market Read

• Event risk today: HIGH — FOMC rate decision at 2:00 PM ET, Powell press conference at 2:30 PM ET. Market pricing: Hold at 3.50-3.75% (65-72% implied) / 25bp hike (28-35%). VIX declining to 18.29 (MID regime, below the 30 threshold). The market has been pricing in lower anxiety heading into the decision. PCE tomorrow (July 30) adds a second consecutive Tier-1 macro day.
• Session character expected: News-driven / two-phase. Pre-2 PM: Compressed range, low directional conviction, institutional positioning. Post-2 PM: Volatility expansion on the decision, extended through the 2:30 PM press conference. The 2:30 press conference runs into the close (market closes at 4:00 PM), creating a structurally unusual close where the closing auction price incorporates active policy commentary rather than the typical end-of-day positioning.
• VIX regime: 18.29 (MID — 18–28). VESPER has no VIX filter by design — holds through all regimes. Irrelevant today because no entry will occur.
• Key levels: SPY prior close 740.79; prior-day range 736.01–742.75; SMA20 746.62 (below SMA20); ATR(14) 7.17. The only level that matters for VESPER — tonight's 16:00 close — is not actionable today.
• Macro backdrop: FOMC-dominated. Two-tier divergence (Dow/industrials holding, tech/semis weak) continued in muted form yesterday. The AI/semi rout of last week has decelerated. VIX declining to 18.29 suggests the market is comfortable with the hold scenario. A surprise hike would be a genuine shock. Tomorrow brings PCE, GDP Q2 preliminary, Initial Claims, Personal Income/Spending, and AMZN/AAPL earnings — a second consecutive Tier-1 day.

Firm-Wide Status: NO-GO — FOMC Decision Day

Firm-wide hard skip for all desks. The FOMC rate decision at 2:00 PM ET and Powell press conference at 2:30 PM ET create a Tier-1 macro event that overrides normal trading. VESPER's unconditional overnight hold mechanism is structurally incompatible with today's session for two specific reasons:

1. Press conference runs into the close. The 2:30 PM press conference extends into the 3:50–4:00 PM MOC entry window. The auction-inclusive 16:00 close price would incorporate active policy commentary, not the normal end-of-day positioning equilibrium — the entry anchor would be a "news print" rather than a structural session boundary.
2. Consecutive Tier-1 macro days. Tomorrow (July 30) brings PCE, GDP, Initial Claims, and Personal Income/Spending — a second consecutive Tier-1 session. A position entered today would exit into tomorrow's 8:30 AM macro data drop, creating a structurally unusual overnight gap that includes both the FOMC aftermath and the PCE print.

No trade today. The unconditional baseline is overridden by the firm-wide hard skip. This is a one-session exception — VESPER resumes its unconditional hold on the next regular session.

VESPER — SPY (unconditional overnight hold — SKIPPED TODAY)

Direction forecast: none — No trade today. No entry.

Position Status (Cycle Closing at 09:31 — Mechanical Exit Only)

The overnight SPY long from the prior session (2026-07-28 entry at $740.84, 30.112 shares, $22,308.26 notional) exits at 09:31 ET today as usual. This is the mechanical close of the prior cycle — not a new trade. The position was entered before the NO-GO was declared. Leaving it open indefinitely is not an option.

Exit at 09:31 ET: Marketable-limit sell at 09:30:00 ET, flat by 09:31. SPY prior close 740.79. The exit is mechanical and unaffected by the NO-GO (the NO-GO governs new entries, not the closing of existing positions).

Prior cycle P&L context: Running net P&L before this exit: −$213.04 net (9 trades, 33.3% WR). The exit from the $740.84 entry (entered on FOMC-eve, 2026-07-28) will close at today's 09:31 open. The overnight gap from yesterday's close to today's open is the 9th cycle observation. Normal single-session noise (σ = 88.6 bps/day).

Tonight's Entry: SKIPPED

No MOC buy at 16:00 ET. The unconditional baseline is overridden by the firm-wide FOMC hard skip. This is the first time VESPER has skipped a session since the start of Phase 3 paper trading (9 prior cycles, all completed).

Structural incompatibility with FOMC day:

• VESPER's MOC entry at 15:50 ET targets the 16:00 auction-inclusive close. On a normal day, the 16:00 close represents end-of-day positioning equilibrium — the price at which the market has finished processing the day's information.
• Today, the 2:30 PM press conference extends into the 16:00 close. The auction price would incorporate active policy commentary, not a settled market view. The entry anchor would be a "news print" — structurally different from the anchor the strategy was validated on.
• Additionally, the exit at 09:31 tomorrow (July 30) would coincide with a PCE + GDP + Initial Claims + Personal Income/Spending data dump at 8:30 AM — a second consecutive Tier-1 morning. The overnight gap from 16:00 ET today to 09:31 ET tomorrow would span FOMC aftermath, overnight Asia/European reaction to the decision, AND the 8:30 AM macro data. This is a different overnight risk structure than the standard session boundary the strategy prices.

Resumption: VESPER resumes unconditional hold on the next regular session (2026-07-30). The standard 16:00 MOC entry and 09:31 exit cycle restarts tomorrow. The NO-GO is a one-session exception, not a pattern change.

Mechanism Watch & Monitors

Note: because no entry occurs tonight, the mechanism watch does NOT update with a new observation today. The trailing means remain at their last cached values (+8.277 / +4.995). The next observation will be added after the 2026-07-30 cycle closes (exit on 2026-07-31).

Key Rules Check

• Unconditional hold: ⚠️ — Overridden by firm-wide NO-GO (FOMC). One-session exception. Resume tomorrow.
• No stops: ✓ — No position is held overnight (no entry)
• SPY only: ✓
• 90% notional, no leverage: ✓ — N/A (no entry)
• Anchor discipline (16:00 / 09:31): ✓ — Exit anchor respected for the prior cycle. No entry anchor needed.
• Cost budget ≤ 1.0 bps/day: ✓ — No entry cost incurred today
• Kill discipline on market data: ✓ — Mechanism watch OK

What I'm Watching

1. 09:31 exit execution quality — Mechanical close of the prior cycle ($740.84 entry). The overnight gap to today's 09:31 open will determine the P&L of the 9th cycle. FOMC-eve volatility can produce larger-than-normal overnight gaps — the exit is mechanical regardless.
2. FOMC decision and press conference — Not for trading, but for understanding the market regime going into tomorrow's resumption. The FOMC outcome (hold vs. hike, Powell's tone on AI/semi capex, balance-sheet path) will shape the overnight premium environment for the next cycle. The mechanism watch is the correct tool for tracking regime changes — not my subjective read of the press conference.
3. Mechanism watch — The trailing-250 and trailing-500 means do not update today (no entry). The cached values will be stale by one observation. Tomorrow's cycle will add the next data point. No action needed — the mechanism watch inspects market data, not my own fills.

Invalidation

VESPER does not invalidate under normal circumstances — the strategy is unconditional. Today's skip is externally imposed by the firm-wide NO-GO, not by a strategy-level invalidation. The strategy resumes tomorrow. The only standing invalidation path (Mechanism Watch trigger: trailing-250 AND trailing-500 < 0.655 bps/day) remains un-triggered.
