Report Summary 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core Viewpoints - The proportion of long and short positions in commodities changed little this week. The factor strength of the non - ferrous sector rebounded, while that of the precious metals and agricultural products sectors declined. The non - ferrous sector was relatively strong in the cross - section, while the chemical and precious metals sectors were relatively weak [2]. - Different commodities have different trends in strategy net value and fundamental factors. For example, in the methanol market, the comprehensive signal was long this week; in the float glass market, it was neutral; in the iron ore market, it remained neutral; and in the Shanghai lead market, it remained short [4][7][9]. 3. Summary by Commodity Methanol - Strategy Net Value: Last week, the supply factor increased by 0.11%, the demand factor increased by 0.13%, the inventory factor increased by 0.02%, and the synthetic factor strengthened by 0.19%. The comprehensive signal this week is long [3][4]. - Fundamental Factors: High import volume of methanol signaled a short on the supply side; increased开工负荷 of acetic acid and MTBE plants signaled a long on the demand side; methanol inventory in East China ports signaled a long on the inventory side; the spot price of inland methanol signaled a short, and the East China basis signaled a long, with the spread side being neutral to short [4]. Float Glass - Strategy Net Value: Last week, the inventory factor decreased by 0.06%, the spread factor weakened by 0.07%, the profit factor increased by 0.06%, and the synthetic factor decreased by 0.05%. The comprehensive signal this week is neutral [7]. - Fundamental Factors: The capacity utilization rate of float glass remained flat, so the supply side remained neutral; the increase in the number of commercial housing transactions in 30 large - and medium - sized cities signaled a long on the demand side; continuous inventory accumulation of domestic float glass enterprises signaled a short on the inventory side; the continuous slight decline in the spot market and the stable recovery of the futures price made the spread side change from a strong short to neutral [7]. Iron Ore - Strategy Net Value: Last week, each factor remained flat compared with the previous week, and the comprehensive signal this week remained neutral [9]. - Fundamental Factors: Decreased shipments from FMG and Rio Tinto and reduced arrivals at northern ports strengthened the long feedback on the supply side; decreased daily port clearance volume and steel mill consumption of domestic sintered ore powder maintained the short signal on the demand side; inventory accumulation at major national ports slightly strengthened the short feedback on the inventory side; the increase in the spot price center strengthened the long feedback on the spread side, and both the inventory and spread sides maintained a neutral signal [9]. Shanghai Lead - Strategy Net Value: Last week, the supply factor decreased by 0.45%, the demand factor weakened by 0.44%, the spread factor decreased by 0.57%, and the synthetic factor weakened by 0.38%. The comprehensive signal this week remained short [9]. - Fundamental Factors: Reduced losses of SMM tax - free recycled lead and a lower ratio of waste battery prices to recycled refined lead prices maintained the short signal on the supply side; inventory reduction in LME and SHFE made the inventory side turn to a long feedback, maintaining a neutral signal; the narrowing of the near - far month discount and the expansion of the spot discount weakened the short feedback on the spread side, and the signal turned to neutral [9]. Sector - Specific Momentum and Structure - Momentum and Structure Data: The report provides momentum and structure data for different sectors, including the egg - related, non - ferrous, energy - chemical, agricultural products, equity index, and precious metals sectors. For example, the non - ferrous sector had a momentum sequence value of 0.06, a momentum cross - section value of 0.93, a term structure value of - 2.2, and a position - holding volume value of - 0.64 [5].
