Hi Firecrest,
Thank you for your comments. I am new too, let's wait and see if anyone else would comment on this.
Actually I am worried a little bit if Z8 doesn't sell or short, like now, the US market has been bull for 8 years and we have a new unconventional administration, a serious market wide correction could happen anytime, in this case, Z8 will suffer. I am thinking that maybe we can put a "safe net" for Z8 to manage the risk like that. I recall someone mentioned this but I couldn't find it.
Hopefully can get some hint here.
Have a nice day
Jeff
