Back in 2007 DPZ started a massive sell-off that took it from a high at $35.67 to a low at $2.61 just 18 months later. Since the bottom in late 2008 DPZ has staged an equally massive comeback and currently trades around $18 and change. The longer-term picture I look at here has to do with the large gap just above $20, and works all the way up to approximately $32.
Speaking of Pizza, check out Papa John's (PZZA), it has recently broken out of resistance around $30 and looks to have enough momentum to continue in the upward direction. Of potential concern is the diminishing volume in PZZA over the past two years.
