AGU and also POT and MOS with it have continued to drop and at least as far as Agrium is concerned the outlook does not look good. The stock dropped below the $61 level and this is a sure fire indication that the a-b-c perfectly symmetrical correction is over. The overlap with previous high points argues that the stock will go further down, most likely to new lows. See previous comments.
Mosaic has already overlapped and was not able to retrace to the 50%+ level at all and therefore looks even more fragile. Potash (not shown) is somewhere in between but also a sell.
