RE:RE:Short Positionnot sure you can short the rights but if you can then what, they are using the funds from short selling the rights to buy or conclude their short position on rt ...they would have been better off buying the righs and then exercising them and using them to conclude a short position on ZENA . If they were to short ZENA.RT they would be required to cover their short position on ZENA.RT options by the 27th (otherwise you are creating options) and that seems to be overly risky even for shorting. Don't think there is shorting of the options but can't say I'm 100% just saying it would be extremely stupid, think they would simply buy ZENA.RT then exercise the right hoping to cover at a net gain.
I am assuming that the actual owner(s) of the rights (as they never really change hands) are not best buds of the shorter and have said "we want no money for the rights-we are not selling them or executing them" be a pretty damn generous position so na don't think so.
