I'll admit I have read fewer than 50 USDA reports in my lifetime. I'm sure there are people on here who have read thousands of reports and traded professionally as a result. Is anyone qualified and willing to provide commentary on these reports as they come out? Or is there a source for credible commentary following the release of these reports?
1) The CBOT/CME may host live/online press conferences with "ag people" who decipher the report. 2) The older-line brokerage firms may have their own in-house people who do the same thing. Sign up for their newsletter for info.
Its very very difficult though to take a position when market opens soon after the reports. Sometimes market goes opposite of probable direction consistent with report or if in direction it opens limit up/down etc. I find them more useful a day or two after release by gauging market reaction when everyone has sobered up.
