In a report published Monday, Morgan Stanley analyst Vincent Andrews upgraded the rating on

(NYSE:

) from Equal-Weight to Overweight, and named a $56.00 price target. In the report, Morgan Stanley noted, "We upgrade Mosaic as we believe its: 1. Phosphate assets are undervalued on an absolute basis; 2. Relative valuation vs. key peer Potash Corp is too severe; and 3. Balance sheet has spare capacity on both an absolute and relative basis. Another large US corn crop is the key risk to our thesis." Mosaic Company closed on Friday at $49.70.
