RE:SPROTT and spot and $@ Dreaminthedream - The artificail imbalance you mentioned is in your head. Sprott is free to speculate in the uranium market just like the carry traders who have an incentive to "ask" down the price of spot uranium to generate margin on a flip.
The price of spot uranium isn't going to trade for less than the cost of production forever. If utilites don't want to buy for less than it costs to produce, Sprott evidently thinks it will be profitable to do so and is buying.
