Ruida Futures(SZ:002961) Rui Da Qi Huo·2025-10-29 09:32Report Investment Rating - No investment rating information provided Core Views - For corn, with the U.S. corn harvest advancing, supply pressure will gradually increase, but the expected lower U.S. corn yield and the Sino - U.S. trade agreement expectation support the market. In China, the new corn supply is increasing, leading to a slight decline in purchase prices. Corn futures prices are in a low - level consolidation [2]. - For corn starch, the increasing supply of raw corn weakens cost support, and the substitution of tapioca starch squeezes market demand. However, the lower - than - usual industry operation rate, good order fulfillment, and slightly decreased inventory are positive factors. Starch futures prices move in sync with the corn market and are recommended for short - term observation [2][3].
