as you all know there is silver and gold tracking stocks. So why not oil tracking? Ever wondered why USO is at $60 now? As you know this "tracking" stock followed crude much like GLD follows gold. But at one point there was a divergence. When crude oil fell last year, the fund that invests (supposedly) in crude (physical) and futures contracts had sold out it's positions and somehow never got back fully into the holding (at the price and size) where it was before the selloff. So now people who invested in USO for the long haul are screwed.
