“The weight of harvest is weighing on cotton prices. We are probably going to be close to 70% harvested pretty soon, so that pressure of processing all the cotton is driving the market down," said Keith Brown, principal at cotton brokers Keith Brown and Co in Moultrie, Georgia.
“The other big factor is this Friday is the delivery of the December contact, all producers and traders have to be out of the contact by Thursday to avoid their delivery."
The weekly crop progress report from US Department of Agriculture (USDA) is due later in the day.
