【摘要】:基于外汇汇率之间满足无套利的三角关系的基本假设,本文利用统计学中两变量之和的方差公式经过变形得出了汇率之间的隐含相关系数。本文结论表明,外汇期权隐含相关系数相比于历史相关系数有着更为优越的预测能力。对组合预测的分析也发现,不同信息的组合无法在任何情况下战胜所有的单独信息预测,但在部分情况下显著优于所有的单独信息预测。
[Abstract]:Based on the assumption that the foreign exchange rate satisfies the triangular relationship without arbitrage, the implicit correlation coefficient between the exchange rates is obtained by using the variance formula of the sum of two variables in statistics. The implicit correlation coefficient of foreign exchange options is superior to the historical correlation coefficient. The analysis of combination forecasting also shows that the combination of different information can not beat all the individual information prediction under any circumstances. In some cases, however, it is significantly better than all individual information predictions.
