OBJECTIVE
USDA NASS publishes the monthly Cold Storage report around the twenty-second of the following month, with the April reading landing around May 22. For US pork, the April entering-month storage position is the industry’s canonical inflection point between winter pork surplus and the summer grilling-season pull. Tight April storage, measured against the ten-year same-month baseline, has empirically preceded summer Lean Hogs rallies with enough signal strength that the industry sidecar literature calls it "the single most important sentiment variable" for the May-through-August window. This signal reads April storage, z-scores against the prior ten April observations, negates the sign so tight storage prints positive (bullish LH summer), bounds with tanh, and gates to May 1 through August 31 each year. In July 2020 the signal fired tight-April positive at plus 0.35 with lean hogs at $44; the market rallied 68 percent over the next sixty days through the COVID-overlap drought-liquidation cycle. In July 2016 the signal fired overhang-April negative at minus 0.33 with lean hogs at $75.68; the market crashed 45 percent over the next sixty days as the pre-built pipeline overhang released into fourth-quarter channels. The memorable twist: the signal is weak at the aggregate statistics level, with event-driven Spearman IC near zero. The payoff lives in the specific-year anchor cases, not the aggregate. Read as a seasonal narrative anchor paired with the other May-August supply reads, not as a standalone trading signal. Read on for the current QUIET state (signal is zero outside the May-August window), the 2016 and 2020 anchor cases, and how to pair with the carcass-weight short-pull read.
LIVE CHART
LH Pork Cold Storage April Anchor
Composite reads 0.000 as of October 30, 2026 — the signal is currently Quiet, outside its May 1 through August 31 propagation window. The April 2026 reading has already been priced through the 2026 summer window; the signal will remain zero until the April 2027 reading propagates on May 1, 2027. The chart shows historical propagation windows as the non-zero bands, with the blue signal line fully flat (zero) in October-April periods and firing in May-August each year. Anchor years 2020 (+0.35 tight) and 2016 (-0.33 overhang) visible as the sharpest event windows.

STATE AND HISTORY
Signal currently Quiet — fires only May 1 through August 31 each year, outside this window the composite is zero. Next propagation window opens May 1, 2027.
ANCHOR CASES, NOT AGGREGATE
Event-days Spearman IC is near zero (+0.006). The thesis plays out in specific anchor years (2020 tight-April → +68% summer rally; 2016 overhang-April → -45% summer collapse) but not reliably in aggregate. Treat as seasonal narrative anchor, not primary trading signal.
HOW TO POSITION
Pair with the carcass-weight signal (near-term short-pull confirmation) and the breeding-inventory signal (ten-month forward supply). The April anchor is a prior; the daily carcass and quarterly breeding reads are the confirming data.
WHAT THE CHART SHOWS
The composite sits at 0.000 as of October 30, 2026 — the signal is Quiet, outside its May 1 through August 31 propagation window. The blue signal line in the chart is fully flat (zero) in October through April periods and fires in May through August each year. The 2020 tight-April anchor case is visible as the sharp positive band in July 2020; the 2016 overhang-April anchor is visible as the sharp negative band in July 2016. The current window has already closed for 2026 — the signal will remain zero until the April 2027 reading propagates on May 1, 2027.
TOP INPUTS FIRING
- Primary composite 0.000 State Quiet; signal is outside May-August propagation window.
- Last active window May-Aug 2026 April 2026 reading propagated May 1 through August 31, 2026. 2026 window has closed; next window opens May 1, 2027.
- Historical anchor years 2020 tight-April → +68 percent summer rally. 2016 overhang-April → -45 percent summer collapse. 2023 tight-April → modest reward. Anchor years, not aggregate reliability.
THE TAKEAWAY
What this means for you today
THE SEASONAL CALL
Composite 0.000, Quiet. The signal is outside its May-August propagation window and will remain zero until May 1, 2027. The April 2026 reading has already been priced out; the April 2027 reading will become the next seasonal anchor.
THE EMPIRICAL CONTEXT
Historical anchor cases: 2020 tight-April → +68 percent summer LH rally (COVID-drought overlap); 2016 overhang-April → -45 percent summer LH crash (pipeline release). The signal has strong narrative power at specific anchors but weak aggregate statistics.
THE HONEST CAVEAT
Event-driven IC is near zero. The signal is educational and narrative. It is not reliable as a standalone trading signal; pair with daily and quarterly supply reads for confirmation.
THE REGIME MAP
The three states, forward returns and sample share
Computed from 8,989 trading days with observable LH fwd60d. Baseline LH fwd60d (unconditional): plus 1.59 percent mean. The signal is zero outside the May-August window; the "Quiet" row aggregates all off-window days.

What this measures
The signal pulls the USDA NASS Cold Storage monthly report (NASS_COLD_STORAGE_PORK, released around the twenty-second of the following month), reads the April pork storage total nationally, computes a z-score against the prior ten April observations (same-month-only history), and negates so tight storage prints positive (bullish-LH a-priori). The signal is tanh-bounded. Daily propagation runs May 1 through August 31 each year; outside this window the signal is zero. Current state is QUIET (October — outside the window).
Why it matters
Why April storage is the industry anchor
The US pork cold-storage cycle has a well-defined annual rhythm: winter build-up (October through March) from the fall slaughter wave, April inflection where the industry transitions from storage-filling to storage-drawdown, then the summer grilling-season pull that drains inventory through August. The entering-April storage position tells the industry how much overhang needs to clear before the summer pull can bid prices higher. Tight April = clear runway for a summer rally; overhang April = full pipeline that must bleed first.
Why the aggregate IC is near zero despite anchor-year power
The signal has strong narrative power at the specific-year anchors (2016 overhang, 2020 tight) but weak aggregate statistics (event-days Spearman IC near zero). Several mechanisms are at work: non-stationary base rate (what counts as "tight" relative to the ten-year baseline shifts as the industry grows); confounding co-cycles (drought, carcass weight, cutout each intermittently dominate); and the fact that the signal is a prior, not a complete read — the actual summer rally magnitude depends on how the entering-storage position interacts with the summer production and export environment.
How to use this signal today
Treat as a seasonal narrative anchor paired with the daily carcass-weight signal and the quarterly breeding-inventory signal. The April reading sets the prior; the daily and quarterly reads confirm or contradict. In the May-August window, size against the composite extreme (above +0.3 or below -0.3) combined with carcass-weight directional confirmation. Currently Quiet — nothing to trade on this signal until May 1, 2027.
