Re: Greenspan' and Derivatives

["Stan Jonas" <sjonas@xxxxxxxxxxxxx>]

Actually since the work of Holbrook Working circa 1940's analytically we've
known
that arbitrage and "hedging" as you describe it are indistinguishable..

Why hedge.. if you think someting is going to go down.. sell it....get out..
Only rationale to "hedge" is that you think you can structure a defacto
positive
expected value arbitrage"...
