We may be getting there sooner rather than later with respect to something like managed futures because it has performed well during this horrible time for just about every other kind of asset. We still do not have decent ways of investing in volatility through ETFs. But maybe somebody will figure that out in the next 10 or 20 years as well. And so eras like the one we're living through right now are going to provide a fertile ground for testing and back testing various kinds of portfolios.
