January soybeans settled at $12.31 1/2 on Friday, up 37 3/4 cents on the week after USDA's November report raised the US soybean yield to a record 53.3 bushels per acre and cut 2026/27 ending stocks to 300 million bushels. USDA also raised exports and announced sales of soybeans to China.
A smaller projected carryout tightens US soybean supply, supporting prices; part of the gain was fund buying from an oversold market, so the rally may be partly technical.
After 747 past bullish report events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.1%), and +0.8% over 20.
