Saw on the CBOE's website that they are going to have a new Dow index option, "Jumbo" Dxl options. Curious, I looked into this, its essentially the DJX but with prices at 1/10th the price of the ol' Dow 30. I currently trade the DJX or Diamonds, dunno about this. I wonder if this will simply sap liquidity from the other contracts. What do you all think about these Jumbos?
