大豆在我国农产品市场占据很大份额,但是我国大豆价格近年来因为各种因素影响而经常变化波动,这无疑不利于我国农产品市场的健康发展以及国计民生的稳定。出于规避大豆现货价格频繁波动导致的风险的目的,可通过大豆期货来实现套期保值,以便大豆运营商锁定成本、增加利润。下面将就大豆现货和期货的最优套期保值比率确定问题做具体分析,并运用OLS模型估计一元线性回归方程,来确定最小方程套期保值比率。
Soybean occupies a large share of the agricultural products market in our country. However, the price of soybean in our country fluctuates frequently due to various factors in recent years, which undoubtedly is not conducive to the healthy development of China’s agricultural products market and the stability of national economy and the people’s livelihood. For the purpose of avoiding the risks caused by frequent fluctuations in the spot price of soybean, soybean futures can be used for hedging, so that the soybean operators can lock in costs and increase profits. The following will be soybean stock and futures optimal hedge ratio determination to do a specific analysis, and use the OLS model to estimate a linear regression equation to determine the minimum equation hedging ratio.
