Shake Shack's stock plummeted 8.35% in the intraday trading session on Monday, as the popular burger chain was declared the most expensive chain in the midst of soaring inflation rates worldwide, particularly in the United States.

With consumers watching their spending more closely due to high inflation, Shake Shack's premium pricing has become a concern. Being labeled as the "most expensive chain" could significantly impact its sales as budget-conscious customers may opt for more affordable options.

The sharp decline in Shake Shack's stock price reflects investors' concerns over the potential adverse impact of high inflation and the company's positioning as a premium brand. If the inflationary environment persists, the chain may need to reevaluate its pricing strategy to remain competitive and maintain customer loyalty.
