In december CMC's cash WTI should actually be back at close to the real cash price
The problem is you have to hold it for the next 5 or 6 months and pay 220% in holding costs for it
I dont think you can go long on CMC Cash at present anyway...they closed it due to all what is going on with this product, you can only reduce positions not open new ones
Seeing how big a trading commodity WTI is, this must be costing them heaps, they must have had some serious issues to do this IMO
