Some confusion on John Hull?s method to calculate Minimum Variance Hedge Ratio

Some confusion on John Hull?s method to calculate Minimum Variance Hedge Ratio

I think there is some doubt here. Does hedge ratio here means money amount ratio or unit amount ratio?

Does mixed-frequency Vector Autoregression help to improve forecasting performance?

<t>I am now using VAR to forecast asset return. I am trying to combine daily asset data with monthly or weekly macroeconomic data in order to improve the forecasting performance of my model. I indeed find some literature on mixed-frequency VAR. Typically the research work by Eric Ghysels. However, I...

How to pick up Vector Autoregression Factor? Return or Price?

<t>I am making a VAR model to forcast future price. The factors include other commodity price, interest rate, FX rate, commodity storage and so on.I find most literature uses asset return as VAR input factors, but my back test result shows that if I directly use prices as input, the result looks muc...

How to hedge exotic interest rate derivative under BGM model?

<t>In M.S. Joshi ?s book ?The concepts of mathematical finance?, it talks a lot on pricing exotic interest rate derivative under BGM model. I think it is mainly based on the Monte Carlo method by simulating the forward rate. However, I am not clear on how to hedge the exotic interest rate derivative...
