This first link from MarketFolly contains the presentation from the winner of the Value Investors Congress contest whose presentation and analysis was a bull case for Jack in the Box.
The above analysis is actually the one I voted for in the contest as I thought it was the best, and the analysis he did in his article is actually what led me to research JACK as a possible investment for myself as he laid out a very good bull case for the company.
This second link is my analysis which is a bear case for Jack in the Box.
We came to the same conclusions about future possibility which he counts on more than I like to. I generally only count in my analysis what I can see now and do not base my valuations on speculation of what could happen in the future.
Please feel free to leave comments on the two articles: Where I might have gone wrong, what I could have done better, etc. I would really appreciate your thoughts.
