2. Vanguard Extended Duration Treasuries ( EDV). "Bond king" Bill Gross, uber-hedger Doug Kass and commodities maven Jim Rogers share one thing in common. They're all shorting U.S. Treasury debt. (Ironically enough, they each appear willing to fight the Fed; perhaps the end of quantitative easing has already been written on the "Wall.") We all know that U.S. Treasury debt is undesirable... at least at these yields and at these bogus ratings. Nevertheless, whenever the world at large gets spooked, investors still run to the perceived safety of the U.S. government. The last time that the longest maturity treasury ETF -- Vanguard Extended Duration - climbed above a 200-day moving average for a substantive period of time? Yep... April/May 2010.
