We believe our broker's VAR model is flawed and so we'd like to find a 3rd party company to analyze a book of options. We aren't looking for a consulting firm, we want someone who already has the software built.

These are liquid, front-month options on futures. Both the futures and options are traded on CME. We aren't looking for margin calculations, we know how to do that with PC-SPAN. We are looking for VAR & risk numbers.

Our broker is moving to Imagine but the move isn't complete yet.

RiskMetrics, perhaps? While I haven't used the actual platform directly, I was the consumer of the output it generated. I recall it being mostly harmless.

Insofar as I may be heard by anything, which may or may not care what I say, I ask, if it matters, that you be forgiven for anything you may have done or failed to do which requires forgiveness...

Riskmetrics is the industry standard but is pretty expensive if I recall correctly. If it's for liquid stuff then could you roll your own?

Have you looked at Sungard, Algo (now @ IBM) or Calypso?

Having the "software already built" is a bit of a naive dream. Do you really want to trust anyone without testing their models? There's a great example of pricing an American option with Bjerksund-Stensland and getting a (small) negative price...apparently that's OK, 'cos no-one does, like, large options deals... Head against Wall

Sadly, I know too many people that have spent years of their life checking the models in these systems...and that's without the effort of making sure that the forward curves that you are using are being imported into the models correctly.

To that point - do you expect someone else to provide your curves and data???

Risk is hard to do - that's why it's often either ignored or done badly.

A girl goes into a bar and asks for an example of double entendre, so the barman gives her one.

Big fan of imagine for a book of (vanilla / listed) options. Very good...

A side note as you brought up SPAN: SPAN is also a risk number. In my view not a bad one. Depending on strategy it's quite often better than VaR as an overall measure for option books.

I'm an options guy and I very seldom had a VaR figure that I believed in at the places I've worked. In fact I've several times in my career had a VaR anti-correlated with my real risk levels..

(I'm not saying it can't be done, I'm just saying it very seldom is done well at all.)

Can anyone comment on the tools from GlobalRisk? I'm interested in their volatility shock matrix and other Firmwide Risk tools rather than the OptionTrader tools that are used to quote spreads.
