Over on CAPS, 380 of the 438 All-Star members who have rated PotashCorp -- or 87% -- believe the stock will outperform the S&P 500. These bulls include sandvig and rbgibbons, both of whom are ranked in the top 1% of our community.

Three weeks ago, sandvig had this to say of the stock:

We do seem to have a dependence on food. That is not likely to change anytime soon. Fertilizer will play an important role in responding to this need. [PotashCorp] is in the enviable position of having a big moat. They control about 1/4 of the world's potash supply.

In a pitch last week, rbgibbons shares that bullishness:

Grain inventories at low levels. Prices are low, but should correct eventually. New Potash mines take a long time to come online, so supply growth is limited, while demand should be high. The combination gives the company pricing power that should make today's prices seem stupidly cheap.
