Steve Meyer of Ever.ag discusses how the CME Lean Hog Index moves in ways that sometimes surprise the market, despite its public formula. He attributes the variability to the relative weights of negotiated and swine/pork formula prices within USDA's Livestock Mandatory Reporting system.
Index behavior affects hog futures settlement and price discovery, but the commentary is about methodology rather than a supply or demand change.
After 61 past neutral report events, Lean Hogs moved a median -0.4% over 5 sessions (48% higher; middle half -1.3% to +1.8%), and +2.1% over 20.
