After much research, Dooker’s team realized that there was a way to crush NAV at an even higher rate. He explained:
“Two times leverage was good, which obviously means that four times leverage is better. Prospective investors should be sure to read the prospectus to understand the effect of four times DAILY leverage and how compounded daily leverage is not the same as compounded long term leverage. We slapped this quadruple leverage on a hybrid basket of natural gas futures and VIX futures in order to accelerate the rate at which the NAV asymptotically approaches zero.”
