currency in pricing

November 17th, 2008, 3:25 pm

Hello,I have to price a structured product, so i need to consider the correlation matrix of my stocks.But I have international stocks in my basket. Do you know how I have to introduce that in my correlation matrix. for instance, if I have usd jpn and european stocks, is it better to use EUR/USD or USD/EUR in my correlation matrix because it is not the same if the third one isJPN/EUR or EUR/JPN?sounds not that smart !!!does anybody have an idea about this question?thx a lot

I don't know if I've understood your question.I would use price quotes all converted in base currency. That will sum up the stock price movements and the FX gains/losses.Anyway, I'm just thinking loud: I am a novice.

mmmh...sounds not a bad idea..but your suggestion is for each date t to consider prices in AUR for instance with the exchange rate of date t (with EUR) and thento calculate returns and then calculate the matrix correlation used after for pricing.But often prices are taken in their money=> returns too=> and in the correlation matrix one introduce crossed exchange rates..but how, exactly?

I meant in what way does the currency come in to the payoff ? Is it quanto or composite ?

ok looks like you are pricing a hybrid to keep things simple it is easy to quote everything in "USD" terms if you have got US stocks in your mix. Recall IBM is really IBM$ (ibm stock price in $ terms). This avoids having to do a quanto/drift adjustment if you are pricing with MC. So EURUSD is the natural quotation and is fine however USDJPY you will want to invert. HTH

ok so if I have IBM, L'oreal, and Mitsubishi in my basket, do I have to put everything in EUR. And just making my pricing with the equities correlation matrix (so without crossing currencies). and the problem of currencies correlation is now ok???
