Panera Bread and Chipotle have both made names for themselves as healthier fast food chain restaurants, but lately the companies' performances and stocks have diverged. So what is Chipotle doing right and what is Panera doing wrong?
"I call it death by a thousand cuts. I think Panera Bread ... has been considerably more differentiated in years past. I think a lot of competitors have tried to steal some of the specialness of what the concept has," Bob Derrington, restaurant analyst for Wunderlich Securities, said in an interview with CNBC's "Closing Bell."
"It's dinged their business,"
Panera reported a 4 percent decline in its second-quarter profit on Tuesday. Sales at company-owned bakery cafes open at least 18 months inched up 0.1 percent. Analysts had expected a 1.6 percent rise, according to Consensus Metrix.
