- CFTC COT Positioning: Large speculative funds (managed money) net position in ZW futures is a 2–4 week leading indicator of price direction. Extreme net-short positions often precede short-covering rallies.
- USDA WASDE Report: Monthly supply/demand revision. Carryout-to-use ratio changes of more than 5% typically move prices $0.10–$0.30/bu within minutes of the noon ET release.
- Weather: Drought stress (NOAA Drought Monitor D2+) during critical growth stages is historically the largest single-day market mover. South Dakota producers should track Corn Belt drought coverage weekly May–August.
