was it you at Socgen ?

<t>I find this very hard to believe, the 4bn loss would have needed Jerome to have been long 30Billion notional of futures atleast and given that the last future roll was in december, he would have had to have built this position over the past few weeks.

Pricing questions - Equity Derivatives

<t>On the topic of stochvol vs local vol. If you have a reasonably good stoch vol model that allows you to fit a lot of the europeans from your vol surface then there is no reason why you would ever want to use LV.

Variance swaps on underlyings other than Equity

With the huge amount of trading in the var swap market for equities, has there any work been done on variance swaps/vol swaps for non equity underlyings i.e. interest rates, CMS rates etc. Any links to relevent papers will be much appreciated.

Option on variance swap

credit spread to price variance swaps

I think that for single stocks there is usually a cap on the variance to ensure that the payout doesnt blow up in event of default, (could be a large cap)
