Merck & Co (NYSE: MRK) shares are falling today after the company reported that FDA approval its new cholesterol drug will likely be delayed until 2013. The FDA first rejected regulatory approval of the drug in April, and requested more information from company studies. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on MRK.

After hitting a one-year high of $61.62 in December, the stock hit a one-year low of $34.49 earlier last month. This morning, MRK opened at $35.40. So far today the stock has hit a low of $35.00 and a high of $35.83. As of 12:25, MRK is trading at $35.03, down 57 cents (-1.6%). The chart for MRK looks bearish and steady, while S&P gives the stock a neutral 3 Stars (out of 5) Hold rating.

For a bearish hedged play on this stock, I would consider an October bear-call credit spread above the $42.50 range. A bear-call credit spread is an options position that combines the purchase and sale of call 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 an 8.7% return in four months as long as MRK is below $42.50 at October expiration. Merck would have to rise by more than 21% before we would start to lose money.

MRK hasn't been above $42.50 since March and has shown resistance around $39 recently. This trade could be risky if the company's earnings (due out in mid-July) are a positive surprise, but even if that happens, this position could be protected by resistance MRK might find at its 50 day moving average, which is currently around $38 and falling.
