Can someone please explain how the futures market actually benefits say for example the corn industry. For example, say I was a farmer and I was able to round up about $10,000 worth of corn.... if I sold or purchased corn futures.... how do I actually benefit from this? Can it save me from overgrowing corn in the fall? Right now, all I can think of futures is just a gambling pit. I'm not so clear as to how does it benefit the actual industry.
