VXX is an excess return index ETF, so as you go along you will be bleeding the rolls (i.e. paying for risk premium). The whole excess return thing makes understanding options on VXX (which are now trading) a bit more difficult too.Quote from nazzdack:
1) Instead of VIX futures, you could trade the VIX (ETF) exchange traded fund as your underlying giving you a potentially infinite time horizon and the ability to continually write call options against that position....until you get called/exercised.
Cash settled. You could have googled that.Quote from rockthecasbah12:
1. Do VIX options close to the VIX cash value, or the VIX futures value?
VXX only rose 4.54% today when the VIX rose 12.30%. [/QUOTE]
VIX is a calculated index based on front expiry, while VXX rolls VIX futures. By it's nature, the futures will be less volatile then spot and going to react to the movement in spot in root-time manner.
