Not an options question per se, but this is probably the best place to ask. How much of a daily drop in SPY would take XIV down to 0?
I know it has a beta of 3 vs SPY so in theory, it would take a 33% daily drop in SPY (that seems unlikely, I'd like to think a 20% drop is the worst that can happen).
At the same time, XIV also has a beta of -0.5 vs ^VIX which means a 4x spike in ^VIX (say, 15 to 60) would wipe out XIV. Such a ^VIX spike doesn't seem that far out. I imagine a 10% drop in the market that comes out-of-the-blue, can easily create this kind of fear.
Is there a better way to analyze this? I just want to know how much money I am willing to keep in XIV.

haha i've always wanted to look at how well the pricing is on options on these products.. because you do realize they are third order derivatives at that point.. they are an exposure from a rolling of futures contracts in which contango and bacwardation have at most times stronger tides they the actual direction of volatility.. and options on those etfs can not possible figure exactly right that changing curve we all love so much.. there is no better example of a non-linearity..
