Domino's Pizza (NYSE: DPZ) continues to post blowout comparable sales growth, with the metric up 8.4% in the most recent quarter as the company rides the growth in delivery. Labor costs are rising, mall traffic is falling, and food deflation had made prices lower at supermarkets; but the biggest problem for the industry appears to be oversaturation. McDonald's (NYSE: MCD) shares have surged nearly 40% this year as new CEO Steve Easterbrook revamped the Golden Arches with moves like all-day breakfast, better value deals, and refranchising company-owned locations.
