Aetna (NYSE: AET) shares are falling today after an analyst at Goldman Sachs downgraded the stock to "Sell" from "Neutral," saying the company will face lower profit margins over the next few years. Other companies in the health-care industry also got downgrades today. 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 AET.

After hitting a one-year high of $60.00 in December, the stock has hit a new one-year low today. This morning, AET opened at $36.98. So far today the stock has hit a low of $36.01 and a high of $37.99. As of 11:55, AET is trading at $37.29, down 2.50 (-6.3%). The chart for AET looks bearish and steady, while S&P gives the stock a positive 4 STARS (out of 5) buy rating.

For a bearish hedged play on this stock, I would consider an August bear-call credit spread above the $45 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 a 4.2% return in six weeks as long as AET is below $45 at August expiration. AET would have to rise by more than 20% before we would start to lose money.
