PFIX has no history so you cannot create a backtest. If your Hypothesis is that interest rates will rise this year is there a better way to allocate capital vs PFIX or Just allocate x% of your portfolio to it. Any suggestions are welcome.
Since PFIX is shorting the 20 year Bond. Using TBT or TMV would be a good approximation. The real question is are rising interests highly correlated with shorting the 20 year bond?
