the current slight downturn on UXA is definately due to the minimum buyers that went into UXA to try and take adavantage of the SPP but now the dates have been extended.
those buyers that bought into UXA only so they would be eligible for the SPP have now pulled out because they only went into it to try and make a quick profit.
nothing wrong with that but its the gist of why the price has had a slight drop.
