OBJECTIVE
Pork sitting in freezers is one of the slowest-moving tells in the lean-hog cycle. When packers are stacking inventory above the prior year’s level, the pipeline is loose and lean-hog futures lean bearish; when they are drawing it down, the setup turns bullish. The Pork Cold Storage signal reads the USDA monthly cold-storage print, scores it against a rolling 504-day baseline, and flips the sign so tight pipeline reads as positive. Readings past plus-or-minus 0.2 are moderate, past plus-or-minus 0.5 are extreme; the current -0.99 is a deep bearish read on Lean Hogs at the edge of the extreme band, 151 sessions into a stress phase. The signal is specialist, not stand-alone. The C+ grade reflects that it belongs inside a multi-factor Lean Hogs composite, not on its own sizing line.
LIVE CHART
Signal trajectory, 504-day window
What the chart is showing right now. The dark line is the sign-flipped pork cold-storage composite in the tanh-bounded space on the left axis. The bronze line is the underlying Lean Hogs nearby price in dollars per hundredweight on the right axis. The dashed horizontal lines mark the plus-or-minus 0.2 moderate and plus-or-minus 0.5 extreme thresholds. The dashed vertical lines mark four historical anchors: the 2008 ethanol feed shock and storage overhang, the 2020 COVID packer closures, the Q3 2020 draw and Lean Hogs low, and the current March 2026 phase start. Band fills are cream throughout rather than green or red at the extremes because the sixty-day IC against Lean Hogs is small-magnitude (-0.121, near the significance threshold), and the useful signal content is in regime context, not sharp directional calls.

TODAY’S PLAYBOOK READING
STATE
Moderate Neg
Reading
Composite -0.990, state Moderate NEG, 158 sessions into a Stress phase. Band: extreme bearish regime. Longest sustained negative phase on record for this signal, matching or exceeding the 2008-09 envelope.
Why it matters
Pork cold storage building hard above its 504-day trend reads as pipeline-loose and bearish for Lean Hogs. The current reading sits in the deep bearish band at the edge of extreme on the sign-flipped scale. The validation grade is C+ because the signal is regime-dominant with weak linear IC — direction is sized off the regime bucket, not off the IC.
Posture
This is a specialist Lean Hogs storage signal, not a stand-alone sizing rule. Treat as one input to a multi-factor Lean Hogs framework alongside the Hog-Corn Ratio (feed-cost confirmer), the Breeding Herd Lead (longest-lead supply), and CFTC positioning. At -0.99 depth, mean-reversion risk starts to dominate the trend-persistence edge; watch for a belly-squeeze flip.
WHAT THE CHART SHOWS
The composite sits at -0.990 in the deep bearish band at the edge of extreme on the sign-flipped scale. Pork cold storage has built meaningfully above its 504-day trend across the current 158-session STRESS phase. What would move it next is the 11/23/2026 (monthly, 11:00 AM ET) USDA NASS Cold Storage print. A below-expectation storage number pulls the composite back toward neutral; a continued build keeps the signal pinned at the extreme-negative floor. Between releases the signal drifts only via the rolling z-score window.

THE TAKEAWAY
What this means for you today
If you hold a structural LH tilt
The composite sits at -0.990 inside the extreme bearish regime on the sign-flipped scale, 158 sessions into a Stress phase. Pork storage is building meaningfully above its 504-day trend — the pipeline is loose. If your tilt is bullish-LH, the signal contradicts you at this depth; the burden of proof shifts to the other lenses in your framework. If your tilt is bearish-LH, this is the strongest confirming lens in the storage leg of the Lean Hogs supply stack, but at -0.99 depth, be aware that mean-reversion risk starts to dominate the trend-persistence edge.
If you trade the monthly release
The next USDA NASS Cold Storage print is 11/23/2026 (monthly, 11:00 AM ET) at 11:00 AM ET. Most of the move happens in the 48-hour pre-release positioning window as desks hedge expectations off USDA Hogs and Pigs breeding-herd flow. A trader who waits for the print to deploy captures the mean-reversion leg, not the signal leg. Watch for a below-expectation storage number (pulls composite toward neutral) or a continued build (pins at extreme-negative floor). Prior-month revisions are routine and can flip the sign — do not size up on a fresh release until the subsequent print confirms direction.
If you build a composite
Use this reading as the storage-leg input in a four-lens Lean Hogs supply framework alongside the Hog-Corn Ratio (feed-cost / producer margin), the Breeding Herd Lead (longest-lead supply), and CFTC positioning (speculator flows). Natural weight is ten-to-fifteen percent given the C+ validation grade and the regime-dominant edge profile. The signal does NOT earn its grade from linear IC; it earns it from the regime axis with deep-bearish bucket forward annualized return at +14.8%. Do not double-weight storage with the daily cutout stack — the monthly cadence and daily cadence capture different reader surfaces.
THE REGIME MAP
The three regime states, forward returns and sample share
State distribution and forward-return sample across 9,047 trading days. The signal is REGIME_DOMINANT: predictive edge concentrates in the tails, mid-range readings carry less information. Direction is sized off the regime bucket, not the linear IC (which is -0.12 at 60d, near the significance threshold).
| State | Phase | Share | Fwd 60d | HAC t | Edge vs baseline | Last firings |
|---|---|---|---|---|---|---|
| Bullish regime | +1 | 40.0% (3621 d) | +6.93% | +5.34pp | Nov 2024, Oct 2024, May 2024 | |
| Normal | 0 | 23.8% (2151 d) | +2.98% | +1.38pp | Feb 2026, Nov 2025, Oct 2024 | |
| Bearish regime TODAY | -1 | 36.2% (3277 d) | +3.77% | +2.18pp | Mar 2026, Jan 2026, Sep 2024 |
Forward returns measured against Lean Hogs 60-day forward price windows across the 9,047-day sample (1990-11-29 to 2026-10-28). The bearish-LH regime (where we are now) has delivered -1.42% mean forward return — three percentage points below the all-sample baseline. The signal is NOT a daily timing lever; it is a monthly-cadence regime read whose edge compounds across quarters inside a composite framework.

Scroll inside the table for the full history. Forward 60-day SPY is measured from each run’s start date; a reader cannot trade off a start-date they only identify in hindsight, so this is a transparency log, not an alpha claim. Asterisked (*) returns are partial. The run is less than 60 trading days old. The full 60-day comparable fills in as more data arrives.
What this measures
The signal reads the USDA NASS monthly Cold Storage report, isolates the total pork line, and computes a YoY change. That raw series is z-scored over a rolling 504-day window with a 60-day minimum. The sign is inverted so that tight pipeline reads positive, loose pipeline reads negative. The final output passes through tanh to bound between -1 and +1. Mechanically: when pork sitting in freezers is building above its seasonal norm, packers and distributors have less reason to bid aggressively for hogs, and lean-hog futures price that in. When cold storage is drawing below its seasonal norm, the opposite holds. The signal captures the medium-horizon (quarterly to annual) component of the inventory cycle. It does not catch single-month plant disruptions or short-term retail promotional pulls; those live in the daily cutout stack. State thresholds: plus-or-minus 0.2 is moderate, plus-or-minus 0.5 is extreme. The BTD module tracks persistent sign-held phases; the current reading has been in a negative phase for 151 sessions (since March 18, 2026), classified as STRESS. For reference, the 2008 to 2009 ethanol feed-shock bearish phase ran roughly 130 to 150 sessions before mean-reversion; the current phase is at or beyond that envelope.
Why it matters
EARLY WARNING
Cold storage leads the Lean Hogs price regime because freezer inventory moves on a quarterly rhythm that packers and distributors read before they re-rate hog bids. The signal correctly tracked the 2008 to 2009 ethanol feed-shock build-and-clear and the 2020 Q2-to-Q3 packer-closure inversion once the April pipeline shock showed up in the May print. It is a monthly-cadence leading indicator for medium-horizon direction, not an early-warning tool for sudden-shock events.
REGIME DEPTH
The reading reflects regime depth, not an entry signal. Values between the +/-0.2 moderate thresholds and the +/-0.5 extreme thresholds correspond to the historical mid-regime; readings beyond +/-0.5 are historically rare and mark the regime tails. Readings between -0.2 and +0.2 are the neutral zone where the signal does not inform a directional read. For sizing decisions, consult a licensed investment professional and see the research brief.
RISK OVERLAY
The current reading of -0.994 has been in the deep bearish band for 152 sessions, longer than the 2008 to 2009 feed-shock envelope. A trader short Lean Hogs on this signal should be aware that at this depth, mean-reversion risk starts to dominate the trend-persistence edge, especially if the belly subcategory turns. July-era bacon-margin squeezes have historically inverted the total-line read inside 30 to 45 days (belly-squeeze fires in 2014, 2017, 2020, 2022). Given the C+ validation grade, treat this as one input to a multi-factor Lean Hogs framework, not a stand-alone sizing rule.
