Mav,
thank you for the input, we all appreciate you insights. I hate to dwell on this but here is the issue i am having with this statement. How is risk reduced as you said? Now i am not talking about margin requirement reduction, i am talking about reducing the risk to your own capital at hand. Say you are short a DOTM veritcal, certainly you can buy gamma in any of the correlated instruments to hedge that particular position and reduce your "margin requirement" by cross-margining but new risk enters the equation now, no? That is your debit for the long gamma if using options, or whatever margin vtrader requires on futures or etfs . The way i see it, the risk to your vertical put position isnt reduced, it is transferred. That doesnt translate to a better returns for less risk as murray alluded to. Perhaps, i am misunderstanding his point.
Having a haircur margin, in and of itself cannot reduce the risk to your own capital. Sure you dont need as much cash in a prop account, but the risk is the same whether you are trading with haircuts or retail margins. Please feel free to correct me on this as i am no expert in cross-margining rules.
