Core Views of the Reports Natural Rubber - Short - term fundamentals change little. The rubber price rises due to the increasing preference for commodities, but there is a risk of a sharp fall after a rise [1]. Methanol - The port may face inventory accumulation pressure in December, but the supply - demand balance sheet is expected to turn to inventory reduction in the first quarter of the next year. The supply - demand pattern in the inland area is expected to be stable, and the price will fluctuate within a narrow range [4].
