In futures, why are there several varieties of a commodity? Help me, great gods
Take corn as an example, 1209 is a contract delivered in September 20 12, and 130 1 is a contract delivered in October 20 13 years/kloc-0. The main contract agricultural products are basically 0 1 0,05,09 for three months. The price problem is like this. Then the price of the distant month is basically the price of the long-short game, which is divorced from the actual spot (but it is also related to a certain extent and cannot be separated endlessly, so there will be arbitrage hedging). I hope it helps you. If you have any other questions, please keep asking.
