careful with some of these ETFs, you don't want to hold them long, could have some sweet gains or some brutal loss, I know got burn with UNG playing Nat gas for a seasonal trade, no winter and an over supply due to fracking success, I knew this but still went ahead and brought and brought more as it fell, still holding a little so go turn up the heat in your house 24/7.
