The head line Ag numbers are bearish. This is allowing POT to decline today. (This is also good for the short-term food inflation, which is good for the economy.) But the macro-trend for Ag is still very much intact, and the sector will continue to need fertilizers/potash at a demanding pace.
As per the technicals, POT has turned with support near 55, and should continue its test to the negative trend line.
I added with the AM weakness.
