In the battle for pizza-chain dominance, it was Papa John's International (PZZA) that took the cake (or rather the crust). The Consumerist reports that the latest results from the University of Michigan's American Customer Satisfaction Index -- tracking points on customer expectations, perceived quality and value, customer complaints, and customer loyalty -- show Papa John's topped its peers in both the pizza business and the fast-food sector overall.

The chain improved its score by 6.7% from last year, hitting 80/100.

Southern Company (SO) closed at $31.88. The U.S. Department of Energy (DOE) committed to loan guarantees to SO for the construction of the first nuclear power unit in the U.S. in more than 30-years. Overall option implied volatility of 19 is near its 26-week average according to Track Data, suggesting non-directional price movement.

Papa John's (PZZA) closed at $22.66. PZZA is expected to provide EPS on February 24. Overall option implied volatility of 38 is near its 26-week average of 37 according to Track Data, suggesting non-directional price movement.

February front month equity options expire Friday February 19.

A friend of mine -- who recently came to LA -- ordered a Papa John's Int'l, Inc. (Nasdaq: PZZA) pizza. She used the Internet. All in all, it was pretty efficient.

Well, according to a recent report, Papa John's has sold about $1 billion in pizzas (over the past seven years). That's certainly a lot of dough, huh? And, as should be no surprise, the growth rate has been stunning: about 50% per year.

There is lots of competition, such as Dominos Pizza (Nasdaq: DPZ) and Pizza Hut. And interestingly enough, Pizza Hut plans to launch a web-enabled widget so you can get pizza at super-fast speeds (I'm sure this will be a big hit for Web 2.0 programmers, who tend to eat pizza at about 2 a.m.).

But, as my friend has experienced, there are some glitches. Ordering online it took two hours for her to get her pizza.
