Thank you daveangel.Most people are directly using that formula on Hull's book for a long time. It is difficult to make a correction now.

<r>Thank you daveangel. I thank your results are correct and I have no problem in calcuating h.However, after obtaining h, how to calculate the number of foward contract N one needs to hold?My result is N = h*QA*S/(QF*F)but John Hull's book suggestsN = h*QA/(QF)Where QA is Size of position being hed...

But the John Hull's book uses asset size amount.<URL url="http://financetrain.com/minimum-variance-hedge-ratio/In">http://financetrain.com/minimum-variance-hedge-ratio/In</URL> your example, I think F and S should be future and spot price.

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

<r>Suppose the spot price is S, forward price is F. S and F are the prices of two correlated asset.

<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.

<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...

<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.
