A fundamental principle of financial theory – “diversification” or “risk spreading” – implies that interest in the new contracts will be high. People and businesses in New York, for example, are overexposed to their local real estate risks, so they should reduce this risk by selling New York home price futures.
金融理论的一个基本原则即“多样化”或“风险分散”意味着这个新的合同将有很高的权益。例如，纽约的市民和企业对他们本地房地产的风险已经不堪重负，所以他们将会通过出售纽约住房价格期货来减少风险。如果价格合理，东京的人将通过购买纽约住房价格期货来承担一部分风险。纽约人仍将安居乐业，但是现在他们将投资风险分散到全球。
