Its pretty interesting how the 460 level has been such clear support for Wheat going back to August of 2014. Notice how the Wheat ETF...WEAT...has underperformed this physical commodity. This is due to the effects of Contango. Basically this means that due to excessive demand created by the ETF, the ETF managers are forced to buy forward futures contracts at artificially high prices but when it comes time to sell them, they receive a regular price. As time goes by this dynamic eats away at the ETFs returns and you can see that here. If you invest in ETFs make sure you understand this because you can be correct in you market analysis but you could still lose money.
