Potash Corp. of Saskatchewan, Inc. (NYSE: POT) shares are soaring today after competitor Mosaic Co. (NYSE: MOS) reported a third-quarter adjusted profit of 99 cents per share, beating analysts' expectations of 95 cents per share. MOS benefited from a global boom in the agricultural sector, which should certainly also be good news for POT. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on POT.

After hitting a one-year low of $54.93 last March, the stock has hit a new one-year high today. POT opened this morning at $173.01. So far today the stock has hit a low of $171.11 and a high of $175.46. As of 12:20, POT is trading at $173.90, up $6.23 (3.7%). The chart for POT bullish but deteriorating.

For a bullish hedged play on this stock, I would consider a May bull-put credit spread below the $130 range. A bull-put credit spread is an options position that combines the purchase and sale of put options to hedge risk in case the stock doesn't do what you think but still leverage nice returns. For this particular trade, we will make a 6.4% return in just six weeks as long as POT is above $130 at May expiration. POT would have to fall by more than 25% before we would start to lose money.

POT hasn't been below $130 since January and has shown support around $154 recently. This trade could be risky if the company's earnings (due out on 4/24) disappoint, but even if that happens, that position could be protected by support the stock might find around $150 from it's 50-day moving average.
