The better burger chain finds itself in good company, though, as peers including McDonald's, Yum! Brands, and Burger King owner Restaurant Brands International are all underperforming so far in 2020.
Shake Shack initially jumped ahead of all these rivals on hopes that the company might surpass management's ambitious growth targets and more than double its store count over time. That enthusiasm waned after its fourth-quarter report showed declining traffic trends that were amplified by temporary closures related to the COVID-19 pandemic.
Shake Shack has noted improving trends as state economies reopened in May and June. However, the company's stores are located predominantly in heavily populated metro areas, especially in the northeastern part of the country. That focus may make it harder for the consumer chain to post as quick a return to growth as rivals like McDonald's, which has a much larger drive-thru service.
