The idea being there is that you want Roth IRAs to hold your riskiest assets because they have the best potential for growth. The real reason that we've included a couple of levered funds in that sample portfolio, the risk parity ultimate is both for experimentation and because it tends to offset the negative expectation of the volatility funds that are in there. So the bottom line is it's not unreasonable to do some experimentation with these sorts of things but you need to be careful out there particularly if you're getting closer to retirement.
