Internal heuristic (no academic backing). Inspired by but NOT faithful to Yu, Hao, Wu, Zhao & Wang (2023), 'Eye in outer space: satellite imageries of container ports can predict world stock returns,' Humanities & Social Sciences Communications 10, Article 383 - that paper trades broad country stock INDICES on DAILY satellite container-coverage-AREA (congestion stock) with a NEGATIVE sign, none of which this generator reproduces.

Citation only, paper link pending.

In plain terms

Internal heuristic: when LA port inbound-container throughput slows vs its ~1yr trend, big importers tend to underperform; when it accelerates, rails/logistics tend to rally. Not validated against an academic paper.

How it works

Internal heuristic on monthly LA inbound-TEU throughput (port_throughput.teu_in, LA-only, monthly POLA HTML scrape). Computes ratio = 4mo MA / 12mo MA, then a 12mo rolling z-score of that ratio; publication-lagged ~12d with T+1 entry. Throughput-momentum read on the LA gateway as a real-economy proxy.

When U.S. monthly imports are surging year-over-year, import-reliant retailers tend to restock and may see firmer demand a quarter later, so the strategy leans long on the import surge and short on the pullback. This is an internal macro heuristic, not a published-paper result: the data only supports a single national-imports signal, not the per-category (apparel vs electronics vs toys) split the cohort labels suggest.
