Chipotle (CMG) stock rose 11% on Thursday on a strong second quarter as the burrito chain's growth strategy took off, offsetting macroeconomic uncertainty and concerns about a cyclosporiasis outbreak. Higher same-store sales growth was driven by a 1.2% increase in average check and a 1.0% increase in transactions. 'Not involved' in cyclospora outbreakMomentum may have stalled in late July due to the cyclospora parasite outbreak. "Our review of Placer.ai traffic data indicates healthy positive traffic growth across all three months of 2Q26," Telsey wrote. "Note, however, traffic in early July remained strong, but it slowed in mid-July, as the cyclospora outbreak related to lettuce gained attention."
