Support was established at $94 per share back at the beginning of July. Price gapped to close at $85.50 on Wednesday, but it seems likely to turn back up. Confirming the gap below support was the largest volume spike in six months, and the relative strength index's move 10 points into oversold territory.

With these indicators in mind, look at the options that expire on Sept. 16. The 85 put can be sold at a bid of 1.55. After trading costs, you would receive a net premium of $146. If the stock price rises as expected, this option will lose time value and end up expiring worthless, or you can close it at a profit. If the stock moves down below the put's strike, the position can be closed or rolled forward to avoid exercise.
