As of Oct 30, 2026. Updated nightly.
OBJECTIVE
Pork sitting in US freezers reveals who is buying it. When freezers are drawing down fast, something is pulling the pork out — usually China (China buys roughly half of US pork exports) or a disease shock that tightens domestic supply. Lean Hogs tend to rally after these demand pulls. This signal reads the USDA monthly Cold Storage print against the same-month five-year seasonal norm, scores it on a bounded regime scale, and flips the sign so bullish-LH readings print positive. The current reading of -0.223 sits in the Normal band — a modest bearish lean, not a sized signal in either direction. The signal is a specialist used inside a Lean Hogs composite rather than on its own. B- grade reflects honest trading of the modern post-2015 regime, where the sharpest edge lives in the deep-draw and deep-build tails.
LIVE CHART
Pork cold storage against the five-year same-month baseline, 1990 to 2026
The dark line is the signal — a reading between -1 and +1 that tells you how far US pork cold storage sits from its five-year seasonal norm (sign-flipped so bullish-LH reads positive). The bronze line is Lean Hogs futures price (right axis). The signal is bullish for Lean Hogs when it rises above +0.9 (green band, deep draw below norm) and bearish when it falls below -0.9 (red band, deep build above norm). Hover any dashed vertical line for the historical story.

Reading
Composite -0.223, state Normal, 231 sessions into the Neutral phase. Pork cold storage is modestly above the five-year same-month seasonal norm — a modest bearish lean, not a sized signal in either direction.
Why it matters
When pork draws below the five-year norm, something is pulling inventory out — usually Chinese demand (~50% of US pork export flow). Four of the signal’s historical draw episodes trace back to Chinese demand or disease shocks (2014 PEDv, 2018-19 ASF, 2020 COVID, 2022 export pull).
Posture
Modern-era demand-pull specialist. The signal is quiet in the middle band; it earns its grade in the deep extremes. In a Lean Hogs composite, pair it with the YoY-framed Pork Cold Storage sibling for both-sided coverage.
WHAT THE CHART SHOWS
The composite sits at -0.223 in the moderate bearish regime. Pork cold storage is modestly above the five-year same-month seasonal norm — a modest bearish lean, but not a sized signal. The signal does not carry a sized directional edge in the Normal band. What would move it next is the 10/23/2026 USDA Cold Storage print: a materially-below-norm reading would push the composite toward deep bullish territory (above +0.9); a materially-above-norm reading would push toward deep bearish territory (below -0.9).
TOP INPUTS FIRING
- Primary composite -0.223 State Normal (moderate bearish regime); 231 sessions into current phase
- Raw z-score -0.23 120-month z-score of the five-year same-month deviation, sign-flipped so bullish-LH reads positive
- 231 sessions in Neutral phase Next NASS Cold Storage release is 10/23/2026; a material print would push toward MODERATE or EXTREME territory
THE TAKEAWAY
What this means for you today
If you already have a view on Lean Hogs
This signal isn’t firing. Pork storage is near its five-year seasonal norm, so there is no sized edge in either direction. If you’re bullish Lean Hogs for another reason (tight breeding herd, favorable hog-corn ratio), this signal is neutral on your view. The next monthly USDA Cold Storage release (10/23/2026) could change that: a storage reading well below the seasonal norm has historically preceded a Lean Hogs rally averaging about 12% over 60 days.
How to trade the signal
Position for a Lean Hogs rally when the signal pushes into the deep-draw (positive) extreme. Position for a decline when it pushes into the deep-build (negative) extreme. Everywhere else — including moderate readings in either direction — treat the signal as quiet and let other signals drive the call. The signal updates once a month after the USDA Cold Storage release; the historical edge plays out over roughly the next 30 to 90 days.
THE REGIME MAP
The three states, forward returns and sample share
Three states, measured over 36 years. The sized edge lives in the deep-bullish and deep-bearish tails (shown in the footnote). Day-to-day the signal spends about half its time in the Neutral middle, where it is quiet.
| State | Phase | Share | Fwd 60d | HAC t | Edge vs baseline | Last firings |
|---|---|---|---|---|---|---|
| Bullish regime | +1 | 32.0% (2892 d) | +1.16% | -0.44pp | Sep 2025, Jan 2025, Oct 2024 | |
| Neutral TODAY | 0 | 48.7% (4406 d) | +0.93% | -0.67pp | Dec 2025, Jun 2025, Dec 2024 | |
| Bearish regime | -1 | 19.4% (1751 d) | +9.32% | +7.73pp | Dec 2019, Mar 2015, Feb 2014 |
When the signal pushes above +0.9 (deep bullish regime, "pork drawing below the five-year seasonal norm"), Lean Hogs have averaged +11.8% over the next 60 trading days in the modern post-2015 era. When it falls below -0.9 (deep bearish regime, "pork building above norm"), Lean Hogs have averaged -13.8% — though this deep-build case has only fired once (2015), so we treat it as a one-case anchor until it fires again.

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 the deviation of each month’s print from the rolling five-year same-month average. That deviation is z-scored at monthly scale over a 120-month rolling window, then the sign is inverted so that pipeline tightness (storage drawing below the seasonal norm) reads positive. The output passes through tanh to bound between -1 and +1. Positive values = bullish-LH direction (draw below norm, demand pull); negative values = bearish-LH direction (build above norm, oversupply). State thresholds apply at plus-or-minus 0.5 (moderate) and plus-or-minus 0.9 (extreme). The signal earns its B- grade in the modern post-2015 era, where Chinese import demand is roughly half of US pork export flow. Deep draws below the five-year norm have historically preceded strong Lean Hogs rallies; deep builds above the norm have preceded Lean Hogs declines. In the mid-range (NORMAL band), the signal does not carry a sized directional edge.
Why it matters
DEMAND-PULL DETECTOR
When US pork cold storage draws materially below the five-year seasonal norm, something has pulled inventory out of freezers faster than history predicts. The dominant driver has been Chinese export demand, which accounts for roughly half of US pork export flow. Four of the signal’s historical deep-draw episodes trace back to Chinese demand or disease shocks: 2014 PEDv shortage, 2018-19 ASF import surge, April-May 2020 COVID processor shock, 2022 export-pull window. The modern post-2015 era is where the signal fires cleanest.
HOW TO TRADE IT
Position for a Lean Hogs rally when the signal pushes into the deep-draw (positive) extreme. Position for a decline when it pushes into the deep-build (negative) extreme. Everywhere else — including moderate readings in either direction — treat the signal as quiet and let other signals drive the call. The signal updates once a month after the USDA Cold Storage release; the historical edge plays out over roughly the next 30 to 90 days.
RISK OVERLAY
The signal is a specialist, not a stand-alone sizing lever. The pooled 36-year linear correlation to Lean Hogs forward returns is small (information coefficient near 0.03 at the 60-day horizon), because the pre-2015 US-China pork trade relationship behaved differently from the modern post-ASF regime. Trade this signal on the regime axis via the deep-draw and deep-build tails, not on linear-correlation sizing. B- validation grade reflects honest two-era accounting documented in the research brief.
GO DEEPER
Thirty-six years of pork cold storage against the five-year norm, as a Lean Hogs demand-pull detector
The research brief walks the mechanism (NASS monthly pork cold storage versus the five-year same-month average, sign-flipped so bullish-LH reads positive), the three historical demand-pull episodes (2014 PEDv, 2018-19 ASF, 2022 export-pull counter-example), the honest B- validation grade with the pre-/post-2015 structural-break disclosure, the modern-era deep-draw +11.8% / deep-build -13.8% fwd60d edge, and the complementary framing against the Pork Cold Storage YoY sibling. Twelve minutes, written for Lean Hogs composite builders.
Signal consumers and siblings
The Lean Hogs analytics stack this drawdown signal plugs into. The five-year-deviation lens compounds when paired with the YoY-framed Pork Cold Storage Inversion sibling, the structural supply reads (Breeding Herd Lead, Hog-Corn Ratio), the event-driven Hogs and Pigs quarterly surprise, and the contrarian CFTC positioning overlay.
