0928 ET - CBOT grain futures rise, ahead of the next quarterly stocks report from the USDA. The move higher is last-minute positioning before the report's release, says Matt Zeller of StoneX in a note. "No major surprises are expected but soybean stocks remain reasonably tight and dependent on a strong crop," says Zeller. Analysts surveyed by WSJ forecast corn stocks through September 1 at 1.92 billion bushels, soybean stocks at 323 million bushels, and wheat stocks are seen at 1.85 billion bushels. Corn stocks are expected to be higher than this time last year, while soybean and wheat stocks are seen lower. CBOT corn rises 0.5%, soybeans up 0.6%, and wheat climbs 0.7%.
