【摘要】:基于外匯匯率之間滿(mǎn)足無(wú)套利的三角關(guān)系的基本假設(shè),本文利用統(tǒng)計(jì)學(xué)中兩變量之和的方差公式經(jīng)過(guò)變形得出了匯率之間的隱含相關(guān)系數(shù)。本文結(jié)論表明,外匯期權(quán)隱含相關(guān)系數(shù)相比于歷史相關(guān)系數(shù)有著更為優(yōu)越的預(yù)測(cè)能力。對(duì)組合預(yù)測(cè)的分析也發(fā)現(xiàn),不同信息的組合無(wú)法在任何情況下戰(zhàn)勝所有的單獨(dú)信息預(yù)測(cè),但在部分情況下顯著優(yōu)于所有的單獨(dú)信息預(yù)測(cè)。
[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.
