Group 4: Agricultural Products Performance - In contrast to industrial commodities, certain agricultural products showed resilience, with starch and corn contracts rising over 1%, leading the commodity market [4]. - The strength in the corn market is attributed to reduced new grain supply from Northeast China and strong demand from feed enterprises, with average feed enterprise inventory increasing by 2.42% week-on-week [4][5]. - The oilseed sector exhibited mixed performance, with soybean oil and meal generally declining, while rapeseed meal saw a rebound after reaching a low point [5].
