JPMorgan analyst Jeffrey Zekauskas points out that the dividend yield of Potash Corp. (POT) is now 7.5%, the highest in his coverage universe. The closest comparable for companies with a market capitalization over $10B is Agrium (AGU) at 3.8%, followed by LyondellBasell (LYB) at 3.4%, Zekauskas tells investors in a research note. Shares of Potash are trading as though conditions in the potash industry are likely to be "materially worse" in the future, the analyst contends. Zekauskas thinks conditions will get worse, but not materially so. He cut his price target for shares of Potash to $23 from $26 and keeps an Overweight rating on the name.
