The Delivery Option on Forward Contracts: A Comment
评论Livingston关于动态交易策略可消除质量选择成本的观点，指出若该策略可行则期货价格无法达到稳定均衡，否则无风险套利机会不存在。
Livingston contends that short futures/long cash traders can eliminate the potential costs of the quality option through use of a dynamic trading strategy. It is proposed here that if this is possible then futures prices will never reach a stable equilibrium. Alternatively, if Livingston's argument is flawed, then no risk-free arbitrage opportunities are likely to be available to either short cash/long futures or long cash/short futures traders. Under such conditions, futures prices will reach an equilibrium when the expected return and risk of each type position are equally attractive.
