Over on CAPS, 4,419 of the 4,606 members who have rated PotashCorp -- some 96% -- believe the stock will outperform the S&P 500 going forward. These bulls include shaileshnita and jigar34.

In late March, shaileshnita keyed in on several of the stock's key ratios (which remain relatively unchanged):

This is a Canadian enterprise with solid fundamentals. It has an impressive P/E, Return on Equity, and Return on Assets. With little debt, this company is well-poised to withstand the recession. It deals with the bread-and-butter segment of our lives which isn't going to shrink.

In a pitch from last week, jigar34 taps the stock's recent weakness as a fertile place to dig in:

PotashCorp seems to be oversold. There is great growth potential here, and the stock appears to be very cheap. Long term prospects for agribusiness, especially fertilizer business, should be great, considering the reducing arable acreage per capita, reducing fresh water resources, and increasing demand for food that we face.
