On CAPS, 96% of the 2,527 members who have rated Mosaic believe the stock will outperform the S&P 500 going forward. These bulls include Nostrademous and All-Star TMFDeej, who is ranked in the top 1% of our community.

Late last year, Nostrademous tapped Mosaic as a solid selection for the new year: "Agriculture will be huge for 2011. Should be considered as a safe and strong option in any portfolio."

As the world's largest producer of phosphate fertilizers, Mosaic remains a highly rated CAPS play on the ever-growing global demand for food. Currently, Mosaic even trades at a P/E (17.5) discount to rivals Agrium (24.9), CF Industries (41.2), and PotashCorp (31.5), as well as other ag-sensitive stocks like Dow Chemical (NYSE: DOW) (20.0) and Monsanto (NYSE: MON) (35.7).

CAPS All-Star TMFDeej elaborates on the bull case:

I am nearly 100% certain that the price of corn is headed higher in 2011. The question is, outside of purchasing corn contracts how can one play this trend?

One way is to purchase stock in Mosaic. According to Forbes, Mosaic's stock is 89% correlated with the price of corn. ...

Add to this the fact that China, which accounts for 20% of global phosphate sales, might begin to restrict exports and the fertilizer may end up being in short supply.

Mosaic's production capacity is scheduled to increase by 60% between now and 2020 so it will be in a position to provide ample supply to an otherwise tight market.
