In India, the Cotton Advisory Board recently announced that mill use is expected to increase by 8.9%, pushing total demand for cotton up nearly 26% year over year. On the supply side, the U.S. Department of Agriculture says that cotton production is expected to fail to keep up with demand for a fifth straight year. This trend has started to eat away at inventories. As of July 31, U.S. stockpiles as of July 31 were at their lowest levels in the past 14 years. Meanwhile, supplier warehouses monitored by the IntercontinentalExchange are down 98% as of Aug. 12. And worldwide stockpiles of the cotton are expected to decrease by 4.1%, to roughly 38% of demand, the lowest ratio since 1994. Moreover, crop damage is expected to take its toll. Floods and landslides in China have destroyed cotton crops, and Pakistan, the world's fourth-largest grower and importer of cotton, has had floods that have destroyed nearly 30% of its crop.

Although supply and demand imbalances indicate that positive price support is likely to occur in cotton, it is important to consider the inherent risks involved with investing in commodities. To help protect against these risks, it's important to use an exit strategy that identifies specific price points at which downward pressure is likely to occur.
