Risk - sell stop when underlying stock price is above $78.65. If that is not ever filled, adding a 30 day time stop to get out. Time stops are good for straight bought options because that can turn into a pretty large theta decay loser if it doesn't go up or down.
Target- A double? Using a trail stop method in it's infancy.
Disclaimer: This is also a trade for me to get my cash portfolio delta lower. May not be your cup of tea for your situation.
