What does a negative number of shares of VXZ mean for my portfolio? Supposed to short them which is unlikely to be possible? Have you backtested the replacements for the delisted ZIV etc yet so we can look at portfolion CAGR comparisons?
It is the same strategy as before the only difference is that you need to sell the VXZ ETFs instead of buying. The performance is slightly better as VXZ has not the rebalancing losses of ZIV. I am sorry if you can not short with your broker. Then there is no way to execute this strategy
