This study proposes an innovative methodology for backing-out implied correlation measures from the variance of Taiwan 50 ETF and its constituent stocks. The volatility estimators are based upon the historical opening, closing, high, low prices. This implied correlation index reflects the market view of the future level of the diversification in the market portfolio represented by the index. The methodology is applied to Taiwan 50 ETF. The statistical properties and the dynamics of the proposed implied correlation measure are examined. The evidence of this study indicates that the implied correlation index fluctuates substantially over time and displays strong dynamic dependence. Moreover, there is a systematic tendency for the implied correlation index to increase when the market index returns decrease, indicating limited diversification when it is needed most. Finally, the Granger causality tests is assessed and we find that the Taiwan 50 index returns Granger causes the weekly TWCIX changes and the weekly TWCIX changes Granger causes the Taiwan 50 index returns.參考文獻 Andersen, T., Bollerslev, T., Diebold, F., & Ebens, H.
