Desk Plan — House Slack — 2026-07-31

Briefing reference: /Users/dadbot/Desktop/ClaudeBod/projects/dadbrain/Analysis/briefings/2026-07-31-pm.md PM: SLACK

Shared Market Read

• Event risk today: LOW — no Tier-1 events. ECI (8:30 AM), Chicago PMI (9:45 AM), Michigan Sentiment (10:00 AM) as mid-tier releases. Firm-wide: GO.
• Session character expected: Trending — mega-cap tech earnings afterglow from the July 30 cluster (MSFT +15.5%, AMZN pre-market +12.75%). AMZN/AAPL divergence is the defining intraday structure. ECI at 8:30 AM may produce a 15-minute vol spike at the open.
• VIX regime: 16.78 (LOW regime, declining from 17.09). For SLACK: structurally irrelevant — the backtest validates profitability across all regimes (PF 1.28–3.01). The binding constraint is the 5-day return threshold, not the VIX level.
• Key levels (IWM): The 292–300 range that held IWM pinned for over a month appears to have broken to the downside. Pre-market IWM at $290.91 (+0.81%), prior close ~$288.57 — below the 292 floor. The two-tier divergence (QQQ 2.7% below SMA20, IWM now weakening) may finally be resolving via a broad risk-off move in small caps rather than the rotation narrative.
• Macro backdrop: Clean macro day with three mid-tier releases. The dominant driver is the earnings afterglow from the July 30 mega-cluster (AMZN, AAPL, MA, SYK, GDDY, DXCM, FSLR). The FOMC's hawkish hold + dovish PCE data has faded as the active narrative.

SLACK — IWM (5-day fixed hold swing)

Position state: Flat. position_ledger.json: {"open_position": null}. No open position. 15% equity sizing available ($3,750 notional on $25K account).

Firm-wide status: GO. No Tier-1 events today. The ECI/Chicago PMI/Michigan Sentiment releases are mid-tier and unlikely to materially affect SLACK's signal — the 5-day return threshold is the only gate, and mid-tier macro data has never been a binding constraint on the mechanism.

Signal setup today: Not present.

IWM's 5-day close-to-close return remains well below the ±4.97% threshold (85th percentile, calibrated 2020-2023, held fixed). The 292–300 range appears to have broken to the downside — IWM prior close ~$288.57, with pre-market at $290.91. Even if the break is real, the 5-day return magnitude is still likely in the -2.5% to -3.5% range, approximately 1.5–2.5pp below the threshold. A single session below 292 does not constitute the sustained 5-day directional extremity the mechanism requires.

TEMPER's retrospective finding (2026-07-24) confirmed — now extended to 15+ sessions: The extended no-signal stretch is expected behavior. The mechanism requires sustained 5-day directional extremity, not a one-session gap. A range-bound-to-breaking regime is still structurally incompatible with the threshold until the break produces 5 consecutive days of directional follow-through. This is not edge degradation.

The two-tier divergence and small-cap weakening: IWM at $288.57 prior close is below the 292 floor that held for over a month. This could be the start of a meaningful downside leg (small caps finally catching up to the tech correction). But for SLACK's mechanism, this is a precondition observation, not a signal — the mechanism needs 5 days of sustained directional extremity, not a one-session range break. If IWM continues lower through next week, monitor the 5-day return gap to threshold.

Sizing vs. event risk: N/A — no position to size. Standard 15% fixed-notional sizing would apply if a signal existed. No event-risk adjustment needed — the COVID-calibrated sizing already covers multi-day event risk.

What I'm watching:

1. IWM's 5-day return vs. ±4.97% — the only gate. The 292–300 range break below 292 is a necessary precondition for a future flagged run, but not sufficient alone. Need sustained follow-through.
2. IWM's close relative to 292 — if IWM closes below 292 for multiple sessions, the range break is real. A bounce back into the range would re-establish the pinning condition.
3. The small-cap rotation narrative — the two-tier divergence (tech selling, small caps resilient) has insulated IWM from developing a directional extremity. If IWM now joins the selloff, a downside signal becomes possible — but only after 5 days of sustained directional extremity. Today is day 1 of that observation at best.

Setup evaluation: Setup not present. p_trade 0.0 reflects the structural gap between IWM's current 5-day return and the ±4.97% threshold. The range break is a precondition signal, not a signal itself.
